Abstract 7 5G promises increased connectivity, high data rates, and ultimately new services. The first 5G release standard in 3GPP will be available by June 2018 with pre-commercial deployment in Korea soon after. Whilst 5G will meet current demand, the exponential rise in demand for wireless connectivity will ultimately require Tbps connectivity in indoor spaces. The future network will use an all optical fibre core, and an ultra-high data rate wireless ‘bridge’ to the User. WORTECS focuses on the goal of ultra-high data rate wireless. High-frequency mm-wave (in the band above 90 GHz) radio communications will be combined with optical wireless communications in the infrared and visible regions of the optical spectrum, using novel heterogeneous networking concepts. A compelling virtual reality application will be used to showcase the capability of the WORTECS network. The project will deliver two Proof-of- Concept demonstrations. An ultra-high density LiFi/Radio network providing multi-Gbps to virtual reality terminals will be developed, and an ultra-high data rate Proof-of-Concept capable of Tbps networking will also be targeted. WORTECS brings together innovative, world leading LiFi SMEs Oledcomm (France) and PureLiFi (UK), Global telecommunications operator Orange (France) and research institutes BCOM (France) and IHP (Germany). These are joined by university research leaders in optical wireless communications from the University of Oxford (UK) and the University of Las Palmas (Spain). The consortium has the dual ambition of proposing new scientific solutions beyond 5G while transferring these technologies from research labs to industrial world. A successful project will both showcase technologies required to alleviate the radio spectrum crunch, and provide substantial benefits to EU citizens through the exploitation of results by WORTECS commercial partners.

Objectives
The main objective of this work package is to define the use cases and related requirements that will drive the theoretical studies and implementation work of WORTECS. In order to be as efficient as possible for simulations and implementation work, three main steps are identified: 1. Overview of already identified use cases in the higher part of the spectrum (State of The Art analysis) 2. Sub-selection of three to five use cases more relevant for bands above 90 GHz and in terms of expected business for the members of the consortium; requirements (key performance indicators + values) will be associated to these use cases in order to drive theoretical studies 3. A single use case (and requirements) will be prioritized for implementation (with a virtual reality application as an initial selection). Prior to this core activity of WP2, a survey of the spectrum above 90 GHz in Europe will be undertaken, in order to prioritize, within WORTECS, the bands that will be used for simulation and implementation purposes.
Description of work and role of partners
WP2 - Use cases, requirements and business perspectives [Months: 1-31] Orange, Oledcomm, B-COM, DLIGHT Task T2.1 : Spectrum: THz band overview (M1 to M3 + M31) Lead partner: ORA Participants: PLF A survey of the spectrum above 90 GHz in Europe will be undertaken based on World Radio Conference 2015 outcomes and individual countries regulation. The World Radio Conference 2019 will take place from Oct. 28th to Nov. 22nd (2019); the WORTECS deliverable on spectrum will then be updated accordingly, if required. This task (and WP2) will be put in sleep mode between M4 and M30. ORA will contribute to the status of spectrum above 90GHz in Europe. PLF will contribute to the status of spectrum between 10,000 nm and 200 nm in Europe. This will include basic eye-safety considerations and potential emission health risks. Task T2.2: Use cases, requirements and business perspective (M1 – M3) Lead partner: ORA Participants: OLD, PLF Many existing collaborative projects, e.g. mmMAGIC , MiWEBA MiWAVES , or standardization initiatives, e.g. inside 3GPP , have identified potential use cases in higher bands spectrum (up to 100 GHz) targeting 5G. In parallel, THz spectrum potential has been investigated as well in collaborative projects (iBROW , TERAPAN ) while generating interest on standardisation side (IEEE 802.15 IG THz , IEEE 802.15.7 ). These multiple sources will be analysed by the WORTECS consortium in order to establish a landscape of use cases relevant for THz spectrum. A sub-selection of 3 to 5 use cases will then be undertaken to define guidelines for theoretical studies, covering diverse environments, including indoor and outdoor situations. Once use cases have been identified, related requirements, e.g. in terms of capacity, throughputs, coverage, latency … , will be agreed between the partners based on inputs from e.g. 3GPP, IEEE, NGMN or ITU (IMT-2020 requirements as defined by ITU will be published mid-2017). Thanks to its involvement in 5G PPP projects, in standardization (3GPP), inside operators’ alliances (NGMN) and in international initiatives (ITU), ORA, as a mobile operator, will contribute on the definition and prioritization of use cases, and to the definition of their related requirements. OLD contribution relates to the selection of use cases based on its impact in society, and public promotion. PLF will contribute specific use cases and a more detailed illustration of how these use cases could be beneficial from a business perspective. In addition, PLF will provide specific system performance requirements which stem from and enable the presented use cases. Task T2.3: Focus on Virtual Reality (M1 – M31) Lead partner: BCM Page 10 of 27 Participants: OLD, PLF For the sake of implementation work, a single use case, likely to be linked to augmented reality (AR) or virtual reality (VR), will be proposed to WP4, at the beginning of the project. To drive the implementation, this task will focus on providing WP3 and WP4 with specifications dedicated to a multi-user VR or AR platform based on business, technical and acceptability studies to justify the soundness of such a choice. Indeed, the commercialization of the first mass market VR headsets (Oculus, Vive, PSVR, etc.) and the development of augmented reality devices (Tango, Hololens, etc.) suggest the democratization not only of consumer market use cases, but also and mostly of professional use cases (learning, design, telepresence, etc.); such use cases will involve a large number of collaborative users requiring high quality contents that will be displayed on devices, with a very low latency (motion-to-photon latency), whether these contents will be rendered distantly or on the device itself. This task will deliver a study evaluating, for a set of relevant VR applications, the optimal trade-off between quality of experience (physiological and psychological acceptability), technical feasibility, and deployment as well as operating costs to ensure the economic viability of the system.

Objectives
The main objective of this work package focuses on the definition of new communication systems based on high frequency radio (> 90 GHz) and optical wireless communications (based on VLC, laser, Infra-Red …) for multi-Gigabits transmission. The cooperation/aggregation between different Radio and optical Wireless Access Technologies (WAT), leading to the design of a specific Hybrid Networks architecture, will allow these to achieve Terabit transmission rates. The main issues to be addressed in order to achieve these objectives are the following: • Technological specifications of Multi-Gigabits radio and wireless optics for virtual reality use-case; • Mutualisation of common Gbps radio and optics analog and baseband processing for transmitter complexity decrease; • Hybrid Network architecture design for wireless terabit transmission; • System modelling and performance evaluation in terms of throughput, latency, positioning, capacity, coverage. Firstly the system definition will be addressed for a virtual reality use-case but diverse set of services, including mixtures of services will also be considered. The WP3 has strong links with the WP2 since the system definition should take into account the requirements issued from the different use-cases and also WP3 will serve WP4 as inputs for specifications to the Hardware (HW) design and implementation.
Description of work and role of partners
WP3 - Terabits system specifications and studies [Months: 1-38] B-COM, Orange, Oledcomm, DLIGHT, UOXF, ULPGC, IHP GMBH This work package is divided into two tasks. Each task containing several sub-tasks, described in the sub-sequent text paragraphs. The different sub-tasks naturally have some dependencies as listed under the same work package. Task 3.1: Gbps radio and Gbps Optical Wireless Communications (OWC) for Virtual Reality transmission (M1-M15) Lead partner: ORA Participants: OLD, BCM, PLF, UOXF, ULP, IHP. Task 3.1 will focus especially on virtual reality use-case transmission on the following items: • Specifications and performance evaluation of a Gbps radio system (radio analog/digital and baseband processing) • Specifications and performance evaluation of a Gbps OWC system (optical/digital and baseband processing) • Common Gbps radio and OWC architecture modem definition with control selection. WP3 will design the wireless radio and OWC Physical Layer system based on the input from WP2. This will include all elements of the transmission chain, including all the digital baseband processing (coding, modulation, link adaptation, framing, detection, estimation …) and the radio and optical front-end parts (antenna design, impairments, ADC/DAC, amplifier, filters,). Positioning and tracking is very challenging especially in Virtual Reality use-case. For the radio PoC WORTECS will enhance the performance of positioning/localization methods using standard radios (2.4 GHz, 5 GHz, 60 GHz, UWB) whereas for the OWC PoC localisation can be provided using the tracking systems required for the line of sight Optical links. Downlink and uplink will be considered, especially considering the asymmetry in data rates. First P2P system performance evaluations will be carried out to make sure the virtual reality requirement is achieved. For system performance modelling, WP3 will adapt propagation channel models already used by partners, including for radio at high (and very high) frequencies (typically up-to 240 GHz) and OWC transmission. Close collaboration between T3.1 and T3.2 will allow models and results to be shared between tasks if relevant. A decision matrix listing all the potential components will be carried out in order to select the main elements that will be implemented in WP4. Of course, radio and optics system component selection and specifications provided to WP4 will take into account complexity evaluation and HW implementation feasibility (taking into account the platforms capabilities and the amount of resources dedicated to the HW implementation). Iterations between WP3 and WP4 will lead to a final specification. After defining each radio and optical system, collaborative work will be to converge as much as possible towards a flexible Radio Frequency (RF) and baseband architecture leading to transmitter complexity decrease. This radio and Page 13 of 27 baseband architecture will take into account Hybrid Network studies concerning the control that has to be applied for selecting/aggregating different radio/optic interfaces leading to high system flexibility. The controller location is one of the key aspects to be studied. This middleware can be defined in several ways, even in the application layer. It has to be studied for answering to specific criteria (latency, throughput, power consumption …). A similar analysis will be also performed to understand how the optical and radio front-ends might be combined. The outputs of the T3.1 will be technical reports and also link level simulators. Task 3.2: Terabits system definition (M1 – M36) Lead partner: UOXF Participants: ORA, OLD, BCM, PLF, ULP, IHP. To achieve Tbps transmission, task 3.2 will focus on the following items: • Advanced radio and OWC system studies (PHY and MAC layers) and performance evaluation • Advanced Hybrid Network system architecture studies allowing to achieve Tbps communication • Integrated Tbps wireless network architecture evaluation Advanced research studies about PHY and MAC layers and Hybrid Network architecture will be carried out in parallel during this task. Results will lead to definition of the Tbps system architecture. Different use-cases will be considered in the evaluation. All these studies will be simulated for performance evaluation by using either radio or optics simulators. Channel modelling based on ray-tracing for radio and optics will be implemented and Front-end impairments will be considered for performance evaluation. Performance will be defined following different metrics such as: QoS (EVM or BLER), capacity, link budget or coverage. This task aims at providing inputs to the WP4 for Terabits system implementation. At M24, a selection of the enablers/ components that will be potentially implemented in WP4 for the V2 HW demonstrator will be undertaken. WP4 will implement a suitable subset of these enablers, which show the key features of Tbps transmission. Partners will contribute to each aspect of these studies as follows: PHY Layer • High throughput and low latency coding schemes such as LDPC codes or block codes with soft decoding (BCM); • Digital or analog (or hybrid digital/analog) MIMO/beamforming/beamsteering technique either for radio or OWC. Transmission with multi-radiated elements allows to increase the data throughput, to increase the coverage or to decrease the radiated power. By applying specific processing to the antenna/LED/laser array, the signal is focused in a specific direction optimizing the link budget of the transmission while minimizing the interference between users. However, MIMO studies have to be done about: o Integrated radio and optics front-end design (IHP, BCM, OLD, PLF); o Modelling of impairments between antenna/LED/laser array elements (UOXF, IHP); o Novel optical concentrator, optimizing the bandwidth (BW) and the Field Of View (UOXF); o Radio and optics baseband processing methods (MIMO precoding methods (BCM) , channel estimation (ULP), synchronization (IHP, OLD, PLF) ); o Multi-User (MU) MIMO transmission (BCM). • Multi-Carrier modulation such as OFDM or new prototype filters such as FBMC for better frequency localization optimizing the spectral efficiency for resource allocation in multiple access scheme such as OFDMA or Wavelength Division Multiplex (WDM) (UOXF, BCM, PLF); • Advanced radio and optical receivers using equalization technique for ISI compensation (IHP); • Very accurate geolocation process for tracking (IHP, UOXF, OLD). MAC layer • Establishing the requirements according to the IEEE 802 (802.2, 802.11 and 802.15) to obtain radio-optics connectivity (OLD, IHP and PLF); • Setting MAC layer requirements that permits to work under multiple IEEE 802 (.7, .11,.15 etc) protocols. These requirements take into account roaming, handover, and multi-access for multi-user/services resource allocation (OLD, IHP and PLF); • Defining required MAC signalling issued from PHY layer that permits to work with multiple IEEE 802 ( .7, .11 or .15) protocols. (IHP) Hybrid Networks • New architecture definition. Indeed, to reach the Terabit/s transmission, aggregation of several wireless access technologies is proposed (multi-connectivity from low frequency band to very high frequency bands). This aggregation needs that the technologies cooperate and are controlled by a “centralized” master (IHP); • Multiple radio and optical wireless interface management in multi-user transmissions (IHP, ORA);
Page 14 of 27 • Definition on metrics selection to manage the different technologies (based on current link quality, current traffic, traffic requirements etc.); (ULP, BCM, IHP) • Interaction with the MAC layer for handover, multi-services and multi-user management (IHP, PLF) ; • Evaluation of the controller at Layer 2.5, just above the MAC layer as in the standard IEEE 1905.1. that needs to consider hardware accelerators located directly in the PHY layer of radio or optics hardware (PLF, IHP); • Study of error recovery schemes realized in Layer 2.5, tailored for wireless links; (IHP) • Definition of new protocols (or usage of common Ethernet); (IHP) • Compatibility with PON for backbone interface connection (UOXF); • All optical communication architecture ; (UOXF) • Study of fast packet forwarding between several heterogeneous wireless technologies, mainly wireless radio and optics (IHP). The outputs of the T3.2 will be technical reports, system model and simulations

The resulting prototype will be capable of establishing cooperation/aggregation between different Radio and Optical Wireless Access Technologies (WAT). Advanced hybrid network architecture, will allow achieving high data rate Terabit transmission. Close collaboration between WP3 and WP4 will define the hardware design, the integration methodology that will lead to the final prototype integration: Optics, Radio and advanced hybrid network. Two demonstrators or PoCs will be created. A first demonstrator will provide a multi-gigabits virtual reality transmission by implementing a wireless optic and a mm-wave radio system. The second demonstrator will target Terabits communication, addressing different use-cases, and will be provided by aggregating several optical wireless and radio systems via a high speed hybrid network controller. WP4 will evaluate the performance of both these demonstrators.
Description of work and role of partners
WP4 - Prototype [Months: 1-38] Oledcomm, Orange, B-COM, DLIGHT, UOXF, ULPGC, IHP GMBH This practical realisation work package is divided into the following tasks. The first one will focus on the multi- gigabits downlink/uplink virtual reality transmission; a PureLifi and Oledcomm prototype providing Optical Wireless Communications (OWC), and a prototype by IHP providing radio communications will be implemented. The second task targets the terabits communication, addressing different use-cases. The University of Oxford (UOXF) will deliver OWC using wireless fibre techniques IHP/BCM will provide a radio prototype. Task 4.1: Gbps radio and Gbps optical wireless communications for virtual reality transmission (M1-M24) Lead partner: PLF Participants: ORA, OLD, BCM, ULP, IHP. This task addresses the virtual reality use-case, which requires several Gbps transmission in downlink, whereas only few kbps are required for the uplink. B-COM will provide an existing virtual reality platform (environment, video content, equipment like high speed PCs, caves, helmets) that uses a wired connection. WORTECs will replace this wired connection with wireless. Two demonstrators will be developed in parallel in tasks 4.1 and 4.2 to achieve these high throughput wireless links. This first demonstrator will combine both wireless optic and radio modems that will be interconnected for switching. Then this first demonstrator represents a multi-Gbps transmission capacity and coverage inside the envisaged environment suitable for the virtual reality use case (prototype Oledcomm/PureLifi and prototype IHP). The wireless optical system consists of a diversity configuration comprising up and down transceivers with seven transmission points for instance, each delivering a 1Gbps rate, while the radio system will use 2 radio streams (at maximum) with very high speed DAC/ ADC and high bandwidth (at least 5 GHz). As VR depends on high accuracy geo positioning, Oledcomm and IHP will contribute to tracking by proposing and developing accurate methods to achieve this. In the Task 4.1, the OWC system will be developed by Oledcomm and pureLiFi. The optical wireless demonstrators designed by Oledcomm and PureLiFi will allow communication between a ceiling transceiver and a mobile transceiver linked to a smartphone or HMD. The most suitable implementation will be investigated and delivered as part of this task. The Access Point (AP or ceiling) module is an array of individual transceivers in a diversity configuration, it is constituted by: 1. A newly designed optical front end element capable to amplify the incoming radiant flux into a photodetector (PD) to take the PD to its response time. 2. Analog signal amplification, equalisation and digital to analogue/analogue to digital converting of the signal in both cases: uplink and downlink at gigabit per second rates. 3. Modulation/demodulation, QAM mapping, multiplexing, framing, error detection and correction. 4. Integration and internal tests of the optical wireless demonstrator.
Page 17 of 27 The final prototype will include geolocation capabilities managed locally or in the internet cloud. For instance, Oledcomm will equip each Tx to enable the tracking a mobile device with a resolution of better than 20 cm. Oledcomm and PureLiFi will collaborate on the delivery of this prototype. Oledcomm will work on the design of Tx/Rx front end optics and PureLiFi will provide the OWC PHY/MAC management in multiuser scheme. The radio prototype will use existing hardware, either from IHP or BCOM. The choice will be made according to the virtual reality requirements and the performance of the platforms, and may include a combination of the two. The digital baseband processing part will be developed in VHDL and implemented in an FPGA component. For the first version of the radio prototype, a data rate up to 20Gbps will be targeted in a point-to-point transmission (with one single data stream). The platform and the system should be capable of integrating a mm-waves radio front-end with one or more antennas including high speed DAC/ADC, accurate local oscillators, analogue filtering, power amplification and one (or more) powerful FPGA for the integration of the baseband processing, including the modulation, the mapping, the framing, the channel coding and advanced detection techniques for the reception part. The objective is to update the current IHP baseband part to increase the data throughput by parallelizing the baseband treatments. A particular attention will be also carried out about the implementation of tracking methods because virtual reality use-case needs very accurate user’ location position. So, bidirectional transmission is mandatory and will be also implemented in the radio system. Efforts and knowledge of different variants of Time of Flight (ToF) measurements will be applied for radio wireless communications or positioning/localization. To aggregate the wireless optical and radio systems, Hybrid Network controller will be implemented either at the MAC or RLC layers. Updates of some existing systems (IEEE 1905 or others) will be considered for implementation as well as of-the-shelf approaches such as fast optical switching using an Ethernet protocol. Integrators and partners involved in the prototypes implementation will work closely with WP3 to ensure that system complexity and choice of components can be made carefully, and that the PoC systems are implemented with minimal complexity, given the challenging targets. In parallel with the design of the wireless optical and radio systems, collaborative work will ensure that common functionalities can be used for both wireless optical and radio transmission (ULP, BCM, ORA, OLD, IHP and PLF). This will enable a common and flexible radio and baseband architecture leading to a transmission complexity decrease. Then, the flexibility will allow a fast reconfiguration of the system that could be able to switch between wireless optical and radio transmission. The reconfiguration will be managed by middleware that will select the appropriate system according to specific criteria, as latency, throughput, and power consumption. The output of the T4.1 is a VR use-case with a common multi-gigabit millimetre waves radio and OWC architecture with control selection (Proof of concept deliverables D4.1 to D4.4, listed here below).
Task 4.2: Terabit system (M1 – M36) Lead partner: UOXF Participants: ORA, BCM, IHP. To achieve Tbps transmission for a whole system, and following task 3.2 goals, T4.2 concerns prototyping. - A first Optical wireless fibre communication network to provide terabit aggregate capacities in indoor environments. - The University of Oxford will implement a Tbps capable system that uses beamsteering to direct light from a fibre through free space to another optical fibre then on to a terminal. Bidirectional communications and operation at 400 Gbps has been demonstrated with such an architecture, and the focus here is the creation of a point-to-multipoint system that is compatible with next generation PONs. The system also provides high precision (several cm) positioning information for terminals within the coverage area using a beacon based tracking system, and the use of this for virtual reality applications will be investigated. - An advanced radio platform. IHP will develop a 240 GHz radio frontend with beamforming capability. For this purpose the IHP SiGe BiCMOS technology will be used. The target baseband signal bandwidth is 25 GHz. The integration of on-chip antennae is planned. For increasing the gain and improving the link-budget, hybrid beamforming is targeted. The front-end chips with antennae will be integrated on a frontend module. To further increase the gain, dielectric lenses may be used. The target data of 500 Gbps, will be reached with several spatial streams. This is equivalent to a spectral efficiency of 10 bps/Hz over all four streams or 2.5 bps/Hz per stream. For the demonstration of the performance, standard high-performance lab equipment will be connected to the RF-frontend module. The demonstration will be performed using a hardware-in-the-loop approach. At IHP very high bandwidth Arbitrary Waveform generators (AWG) and vector signal analyzers (VSA) are available for this purpose. Specialized modulation and coding schemes as well as MIMO processing algorithms will be developed in MATLAB. The transmit/receive data will be generated/processed on a high performance PC connected to AWG/VSA, using MATLAB. Experiments in realistic environments linked with the targeted use-cases will show the performance of the developed algorithms and RF-module. Using a time-stamp Page 18 of 27 approach for the transmitted and received packets, the data can be used for ranging and further on for positioning of mobile terminals. Simultaneously, this hardware-in-the-loop setup, can be used for channel measurements at 240 GHz under various environmental conditions. - A Hybrid Network management controller. IHP will implement the complete Layer 2.5 as software solution (in Linux kernel- and user space). First version of Layer 2.5 will be used in the V1 demonstrator (Task 4.1). However, IHP will work further on Layer 2.5 software version to have the complete solution by the end of the project. To achieve high forwarding speeds, parallel data processing and some protocol-based solutions, such as frame aggregation have to be used. The achieving of a few Gbps data forwarding speed with this software version is expected and will be integrated in the V1 demonstrator. To support higher data rates, dozens of Gbps and more, the data plane must be realized in hardware, or using dedicated network processors. In this project IHP will examine the data plane implemented on FPGA platform. However, the FPGA implementation of data plane will include only basic functionality needed to examine and evaluate frame processing using hardware. Nevertheless, this FPGA-based implementation will not be part of the integrated demonstrator (V2, with ultra-high data forwarding) due to additional requirement on resources, high extra costs, and manpower.

WORTECS 4 1. Excellence Background and challenge The information networks of the future will consist of an all-optical core, with wireless access technologies wherever possible, and evolution to this model is already underway.
Figure 1.1. Throughput capacity trend for PON [EFF16]. The ‘reach’ of the fibre network is already reaching many homes, and will further extend to individual spaces within homes and office buildings. Figure 1.1 shows the development of Passive Optical Network (PON) architectures, demonstrating that capacities of 100Gigabits per second (Gbps) will be available by 2019. Increasing this data rate is already ongoing by Wavelength Division Multiplexing (WDM) solution. This will ensure that ultra-high data rate services will be available to citizens whenever they are indoors.
Figure 1.2. Global mobile traffic (montly Exabytes) [ERC16].
WORTECS 5 The traffic and demand for wireless services are also growing exponentially. Figure 1.2 shows the current growth in mobile data traffic, and a prediction for its future increase. Much of this traffic will be for data services indoors. The nature of these services is also evolving with the rapid increase in the number of devices and new image based services. A new generation of 3D displays, with the ability to create Virtual Reality (VR) environments, is being launched. Virtual Reality places significant demands on bandwidth, latency, positioning and mobility, and this will become more challenging as systems evolve and consumers demand of Quality of Experience (QoE) increase.
Figure 1.3.Radio and wireless optic standard and product panorama. The wireless infrastructure provides the bridge between the fixed fibre network and the devices that deliver the services to end-users. Figure 1.3 shows the rich set of wireless technologies that are evolving as parts of the future wireless infrastructure. The key goals of this evolution are: (1) Identification and exploitation of new spectrum in order to provide additional capacity. This has led to the use of higher carrier frequencies, with almost Line-Of-Sight (LOS) propagation and the resulting need to manage propagation paths. (2) Efficient use of multiple radio/wireless optic technologies available in most devices and indoor areas. (3) Define solutions to address multiple use cases. The goals set for 5G are already stringent, but may not be able to address the future unknown needs that may arise in a beyond 2020 horizon. Beyond 5G mobile network will require:
Extremely high data rate with low latency for point to point and point to multipoint communications (Tbps/space).
Hybrid networks able to manage the available capacity. WORTECS consortium will address these challenging requirements thanks to the experience of its partners. WORTECS brings together several European industrial players (Orange, B-COM and OledComm - France, IHP - Germany, PureLifi – UK) as well as academics (University of Oxford - UK and University of Las Palmas – Spain). Figure 1.4 shows how WORTECS will meet these capacity demands. The WORTECs concept will emphasize:
WORTECS 6 High density LiFi (Visible Light Communications - VLC) expertise provided by industry leaders Oledcomm (OLD) and PureLiFi (PLF). Ultra-high data rate infra-red expertise links provided by University of Oxford (UOXF). Ultra-high data rate radio links expertise provided by IHP (IHP) and B-COM (BCM). A compelling Virtual Reality application expertise provided by BCM. Multi-technologies management led by IHP, Orange (ORA), University of Las Palmas (ULP) and BCM. The primary challenge addressed in the project is the development of a system able to deliver ultra-high throughput (up to Tbps). It will also meet stringent low latency and positioning requirements to address not only the anticipated end-users traffic demands after the 2020 time frame, but also the potential new and currently unknown demands that may arise as a consequence of new ways of using wireless communication networks in the future. Key conceptual elements to be investigated, enabling such low latency and positioning requirements, include innovative network protocol, signal processing algorithms and access schemes. Demonstrators built on novel and advanced high performance computing techniques will be developed and used to check link- and system-level performance in representative environments.

1.2 Relation to the work programme The WORTECS project, addresses the “Networking research beyond 5G” research topic outlined in the call of the Horizon 2020 (H2020) Work Programme 2016-2017. The scope of the project includes “Scientific and technology advances for novel use of the spectrum potential”.
WORTECS 8 WORTECS will investigate high frequency bands (above 90 GHz), Visible Light and Infrared (IR) regions of the spectrum, addressing all the potential wireless technologies described in the call (radio/optical), as well as digital communications, in a single proposal. This will allow a critical comparison of these technologies, with high innovation potential in all of them. Advanced signal processing will be developed in high-frequency radio bands and combined together with novel wireless optic prototypes, leading to novel and exploitable results. WORTECS will also address novel Demand-attentive and cooperation networking alternative to 5G in order to combine the wireless approaches to achieve the ultra-high data rates we are targeting. This will be illustrated on an example use case in the field of Virtual Reality (VR). Table 1.2 shows the specific challenges addressed within this scope.

This work will help operational analysis.
1.3 Concept and methodology (a) Concept WORTECS will provide the indoor wireless networking capabilities required for emerging ultra-high data rate services such as Virtual Reality, using a combination of: 1) Ultra-high speed radio and optical links. 2) Multi user management radio and Light Fidelity (LiFi). 3) Hybrid networks design. These enhanced network capabilities will be used to link new ultra-high capacity Passive Optical Network (PONs) to wireless appliances, providing an enabling technology for future services. Figure 1.5 and 1.6 show schematics of the two WORTECS prototypes. Figure 1.5 shows LiFi and radio network that provides multi Gbps per user with positioning and low latency to a VR headset, with the focus of Tbps capacity within the space. Figure 1.6 illustrates the focus on ultra-high data rate links, with the aim of beyond 100 Gbps per user, working towards 1Tbps. To validate the technical choices, link budget estimations, link and system simulations and proof of concept experiments will be done. WORTECS will also reuse results from European and National Projects (Omega, mmMAGIC, METIS, Acemind) to select relevant use cases and define related requirements, section 1.4 will present into details how WORTECS plans to reuse the results of these researches
WORTECS 10
WORTECS aims at taking these concepts to Technology Readiness Level - TRL 4-5 (lab validation/validation in a relevant environment) using a test-space in BCM premises, and a highly demanding wireless VR use case.
(b) Methodology The project focus is to create two proofs of concept experiments, which provide ultra-high data rate connectivity to enable an extremely challenging virtual reality use case.
Demonstrator 1 (T0+24 months): This focuses on a high density network (see Figure 1.5) that can provide > 1 Gbps per user (full duplex) with multi user, but has the potential to provide Tbps per room, or coverage ‘space’. This will be achieved using radio (IHP), and Optical Wireless Communications (PureLiFi – PLF and Oledcomm - OLD). The radio PoC (IHP) will be based on one stream able to transmit up to 20 Gbps in a point-to-point configuration (representing a substantial increase in the state of the art). The LiFi systems (PLF and OLD) will provide bandwidth density and user data rates beyond what is available in commercial systems today (~40Mbps), again showing substantial increases up to several Gbps on point to multipoint configuration. Virtual Reality is targeted as a demanding application, and these systems will be linked to a BCOM (BCM) server in order to provide the Virtual Reality content to head mounted display terminals.
Figure 1.5 Demonstrator V1 example (T0+24 months).
Demonstrator 2 (T0+38 months): This focuses on ultra-high data rate links (see Figure 1.6). University of Oxford (UOXF) will use a novel fibre-optical wireless-fibre approach to create Tbps capable links. Additionally, this will lead to cm precision positioning data for terminals. IHP/BCM will focus on ultra-high data rate Radio links and IHP will present new Hybrid Networks design based on layer 2.5. The capability to create both types of link in the
WORTECS 11 same environment presents a unique opportunity to compare the use of these different regions of the electromagnetic spectrum.
Figure 1.6 Demonstrator V2 example (T0+38 months).
WORTECS will also define a flexible, common architecture that will allow best use of these high data rate resources. Figure 1.7 shows a possible architecture for a common Radio/Optical transceiver, where processing resources are shared across optics and radio. Such approaches will be evaluated, using metrics including latency, availability, and the ability to provide ultra-high data rate connectivity.
Figure 1.7.Prototype block diagram example.
This will be enabled with work in 6 closely coupled workpackages: WP1 - Management, WP2 - Scenarios, use cases, requirements, WP3 - System Studies, WP4 - Proof of concept development, WP5 - Dissemination and standardisation.

1.4 Ambition The following sections present WORTECS ambitions against state-of-the-art in four fields of research. WORTECS builds upon most advanced research in these fields to enhance already available products and technologies. WORTECS is a highly ambitious programme, with success leading to new and groundbreaking results, including
Multi-Gbps Visible Light Communications systems delivering data to Virtual Reality Headsets. (There are currently no VLC systems delivering Gbps)
Tbps capable systems incorporating ultra-high data rate optical wireless and radio wireless (There are no such demonstrations where both these techniques have been used together).
Multi user ultra-high data rate wireless transmission prototype demonstrating the low latency and mobility necessary for virtual reality, as well as localisation and tracking to cm accuracy. All these are extremely challenging objectives and WORTECS has high innovation potential as a result. Advances beyond the state of the art in each of the key areas are summarised below.
1.4.1 Virtual Reality (VR) State-of-the-art Virtual reality has followed several steps from the 1960’s to the present day. From its foundation in 60’s and 70’s with the “Sensorama” from Morton Heilig as well as the “Sword of Damocles” from Ivan Sutherland, to its technological development in the 80’s, followed by its experimentations in the 90’s, and its industrial roll-out during the 2000’s, it has taken more than 45 years to reach, thanks to displays and sensor improvements driven by the mobile phone market, the general application of the technique, beginning with the first Oculus Rift Dev Kit 1 in 2012. Year 2016 marks a turning point with the first commercial versions of Head-Mounted Displays (HMD) addressing the consumer market (Samsung Gear VR, HTC/Valve Vive, Oculus Rift CV1 and Sony Playstation VR). All the VR community is impatiently waiting for the end-user feedback that will drive the future of the Virtual Reality, and first answers to many important questions are expected in 2017. Nevertheless, industry has invested billions of dollars in VR technology, essentially for games and entertainment purposes targeting different platforms such as consoles, PC and mobiles (see Figure 1.8).
Figure 1.8. On left, Sector activities targeting virtual reality technology, on right, worldwide virtual reality market forecast by platform [VIR16].
WORTECS 13
These different platforms provide developers with different capabilities, and end-users with different quality of experience. Thus head-mounted displays offer various degrees of freedom and range for navigation (rotation only, desktop-scale, room-scale, …), different display resolutions and frequencies, fields of view, as well as extra capabilities such as eye tracking (see Figure 1.9).
It is important to understand that the user experience is directly related to HMD capabilities. Indeed, HMD are facing a usability issue that remains a main challenge for VR adoption: the cybersickness or motion sickness. This unpleasant feeling is due to an inconsistency between virtual and real feedbacks. The most known inconsistency comes from an antagonistic user motion estimation based on visual feedback of the virtual world on one side and on proprioceptive feedback analyzed by the internal ear of a static user on the other side. In this way, a first-person view experience where the user embodies an avatar walking in a virtual world could generate nausea if the movement of the user in the real space does not perfectly map the movements of its avatar in the virtual world. In the same way, if the latency between the user motion and the visual feedback of this motion in the HMD is too long (> 20ms), so called motion to photon latency, the user can feel nauseous. As the user brain is able to detect any artifact that does not seem natural, the virtual simulation should be as real as possible, and many technology limitations can generate cybersickness and reduce user experience, including low display resolution, frequency and field of view.
Figure 1.9. Classification of HMD according to their capabilities (navigation range, display resolution, frame rate, and other characteristics).
Beyond state-of-the-art Thus, to offer an optimal quality of experience to virtual reality users, a VR system should provide users with large range navigation, high resolution (and higher for very wide field of view) as well as high frequency displays. Unfortunately, these requirements are in conflict with one another. For example, a large area navigation space requires a wireless VR system. Such examples based on smartphones, embed rendering capabilities and offers free-navigation, but these are not powerful enough for a high resolution and frequency rendering. In the same way, solutions based on
WORTECS 14 a backpack embedding rendering resources can be considered as wireless, but the user needs to carry a supplementary load that reduces user experience. Currently, the optimal solution uses a remote rendering capacity with a high bandwidth and low latency wireless link to the HMD. This solution is close to being commercialized using a video streaming solution based on WiGig wireless communications. Although WiGig can support current HMD capabilities (4K at 90fps), this technology will quickly reach its bandwidth limits. Compression of the video introduces latency, so increasing the bandwidth of the wireless link is the only viable solution. In order to anticipate the next generation of HMD, we estimate that the wireless solution should support at least a bandwidth of 100 Gbps/user (ideally > 200 Gbps/user) in order to respect the maximum of 3ms latency due to low latency video encoding, which is a WORTECS objective. Moreover, as VR experience will become multi-user, the WORTECS system has to support multi-channel to stream a dedicated rendering to each user navigating within the VR system. The last WORTECS objective is dedicated to a precise positioning.
1.4.2 Radio communication State-of-the-art There is little previous work on the design and implementation of PHY / MAC radio technologies in spectrum bands above 90GHz due to the focus in bands up to 90GHz as part of 5G efforts (see for instance ICT-FP7 EU/JP MiWEBA [MIW16], ICT-FP7 MiWAVES [MIW16] and the 5G-PPP mm-MAGIC [MMM16] projects). These offer solutionst that might be adapted to higher bands. There is some work as well on the components required for such systems. This is one of the objectives of M3TERA project [M3T16]; Ericsson, a partner of this project, has previously developed (with Chalmers University [CHA16] a wireless transmit and receive circuit that operates at 140GHz (transmission rate of 40 Gbps in labs), that will be enhanced during the M3TERA project.
The iBROW project (http://ibrow-project.eu/) aims to achieve 10 Gbps as a means to pave the way for future 100 Gbps wireless communications by exploiting the wide available bandwidth in the mm-wave and THz frequency spectrum.The TWEETHER project [TWE16] focuses on 92- 95GHz band with a capacity target up to 10 Gbps. The TERAPAN project [TER16] focused on terahertz communication systems for indoor environments. The latest progress in ASIC fabrication technologies allows a cost efficient implementation of systems for high frequency operation. In particular highly scaled CMOS technologies, as well as SiG-BiCMOS technologies, provide maximum frequencies of active devices in the range of 200 to 500 GHz [DOT16]. Some of the latest technologies are capable of reaching even 700 GHz [DOT16b]. Advances in the design of compound semiconductors allow moving to even higher frequency bands for wireless communications.
Beyond state-of-the-art In WORTECS we target the development of a novel 240 GHz phased array system. To enable ultra-high speed data rate communication, 240 GHz broadband transmitters and receivers will be developed. The relatively low output power available at such extremely high frequencies will be overcome by the use of phased array architectures. The possibility of using either on-chip or in-package antennas will be explored, taking into account required system specifications and overall cost. In [SJL15] there is a two-level hierarchical LOS-MIMO system that achieves spatial multiplexing gain on top of high beamforming gain. It consists of antenna subarrays with high WORTECS 15 beamforming gain that are arranged at optimal spacing. The evaluation of the transmit power per bit showed great potential in obtaining high system efficiency. The link budget is promising for achieving a throughput in excess of 100 Gbps with reasonable array sizes. Theoretically, for transceiver arrays of size of 25 cm x 25 cm, a data-rate of 500 Gbps is achievable. Hybrid beamforming techniques, that combine analog and digital processing, provide greater implementation flexibility in comparison to fixed analog solutions and lower hardware cost in comparison to digital solutions. With hybrid processing systems a transmit power efficiency of better than 10 pJ/bit is feasible [CHL16]. On-chip antenna implementations allow a robust module design without high losses on transmission lines. Channel estimation and synchronization are fundamental tasks that need to be solved for every communications system. The channel characteristics at 240 GHz will be investigated in this context. The inherent structure of LoS (Line of Sight) MIMO channels offers some capabilities to reduce complexity of the estimation algorithms, which was partly investigated in the context of project maximum MIMO [HAE16]. In this project, a 2D LoS MIMO channel model was built for the concept presented in [SJL15] to provide means for the algorithm development and simulation in the MATLAB/Simulink environment. Various channel imperfections such as antenna array translation and rotation, wind effect and pole vibration are included to emulate realistic channel conditions. While other works on 2D LoS MIMO channels consider only isotropic antenna models, the proposed model uses microstrip element radiation patterns for a more precise link budget calculation. The developed models will be updated with 240 GHz channel parameters and used for the system simulation model. Achieving high throughput in spatial multiplexing MIMO systems with the simultaneous transmission of multiple data streams requires highly parallel baseband processing. The concept of lane-based baseband architectures is investigated for the independent processing of data streams with adaptive coding and modulation. This lanes concept is also advantageous for achieving low processing latency. For real-time-critical computationally intensive matrix operations performed in the joint MIMO processing sections, a systolic array implementation in programmable logic is considered. Developing a practical MIMO communication system with the envisioned performance parameters is a non-trivial task due to the lack of availability of hardware modules that are capable of operating at the enormous system bandwidths at carrier frequencies above 90 GHz. An initial hardware-in-the-loop test with the developed RF-Frontend modules will be used to verify the PHY functionality and performance. For this purpose high-performance arbitrary waveform generators (AWG) and Vector Signal Analysers (VSA) will be used. Since positioning functionality becomes more and more important, both for end-user applications as well as for the operational purposes of large networks, we will consider the integration of positioning in the PHY and MAC layer at the very start of the system design. This network based positioning approach will work independently of GPS and will be based on Time-of-Flight (ToF) measurements of the radio packets. The target accuracy is few centimetres. This allows applications such as geo-fencing and indoor navigation.
1.4.3 Optical Wireless Communication (OWC) State-of-the-art in visible light communications State-of-the-art Visible Light Communications (VLC) or Light Fidelity (LiFi) systems targeting the market are being produced by two members of WORTECS consortium: OLD and PLF. OLD has developed three main operating systems for either Geolocation or internet applications. Geolocation services are divided in two kinds of technologies; the first involves low cost transmitters acting as beacons and requires that the receivers have integrated photodetectors, WORTECS 16 nevertheless, attending smartphone photodetector integration, external sensors are easily connected to Rx devices. The second system consists on low-rate transceivers using Ethernet: a) Transmitter network for indoor geolocation. The system includes all the layers, from PHY to applications and cloud services. This geolocation system is in the market. b) Geolocation system based in low-rate transceivers. Data rates do not exceed 1Mbps. The system has been designed to cope with autonomous machine operations in indoor environments. The system design includes all the layers, from PHY to applications. The system is in the market. The third system in the market concerns internet by VLC. This VLC internet has an operational rate of 10 Mbps symmetrical, and is currently sold mainly in hospital market where RF wavelength must be avoided to prevent interference with medical equipment.
PLF offers a fully-networked LiFi solution (marketed as the LiFi-X), using visible light for the dual purpose of illumination and downlink communication, as well as infrared (IR) light for uplink communication. The system is capable of delivering 40 Mbps on the downlink as well 40 Mbps on the uplink. Furthermore, it supports up to 8 users being served by a single access point, where multiple access is handled seamlessly. In addition, the LiFi-X provides seamless handover enabling a user to freely roam within a well-lit environment serviced by multiple LiFi-X access points. For networking purposes, the LiFi-X provides 802.1X interface to higher layers. The system has further been designed to accommodate an arbitrary off-the-shelf luminaire in a “plug-and-play” fashion. The LiFi-X can be both mains powered as well as powered using Power over Ethernet (PoE).
UOXF and collaborators have demonstrated data transmission using OFDM and custom high-bandwidth LEDs with rates of 5Gbps for single channels [FER16]and 10Gbps for WDM, all using off-line processing [CHU16] Also, white light generated using a blue laser and yellow phosphor colour converter was used to transmit data at 10 Gbps, using typical room illumination levels. These represent the state-of-the-art for VLC data rates. UOXF have also developed novel antennas based on fluorescent materials, which overcome the limit of étendue (the trade-off between FOV and optical gain) [MAN16]. Measured results now exceed the theoretical maximum performance of alternatives, representing the state-of-the-art in this aspect of receiver performance. UOXF and collaborators have also demonstrated the first integrated MIMO receivers, again the state-of-the-art [RAJ15].
Beyond state-of-the-art in visible light communications Work in the consortium will focus on going beyond the state of the art in system performance, by substantially reducing the performance gap between lab-based off-line demonstrations and market oriented real-time devices capable of integration into complete systems. In the consortium, researchers and specialists in universities (UOXF, ULP) and industry (OLD, PLF) will closely work together from the modelling and designing phases to implement the high- speed system providing indoor users with high transmission rates beyond several Gbps in multiuser applications.
Novel antennas will be studied and modelled, which can significantly contribute to miniaturising the user equipment. A MAC layer capable of switching to different transmission rates (for instance IEEE 802.15.7 standard and its newer version) as well as the IP layers will be studied. Also, integration of optical wireless systems with radio technologies will be applied, which maximises the advantages of the two technologies. This will lead to multi-Gbps capable systems, an increase in almost two orders of magnitude in data rate compared with state-of-the-art VLC systems offering 10s of Mbps user rates.
WORTECS 17
State-of-the-art in infrared (IR) communications Tbps data rates can now be achieved in optical fibre systems, and infrared OWC links based on these technologies is a growing research area. Typically, light from an optical fibre is collimated, propagates as a narrow beam through free space (the wireless link), and is then coupled back down a fibre. The wireless link is transparent, potentially bidirectional, and does not need an optoelectronics interfaces. The challenge is aligning the link and using beamsteering to allow beam pointing and tracking over a broad coverage area. Figure 1.10 shows the data rates achieved vs. coverage area. Many links have no coverage area, as they are fixed point to point examples. Ultrafast indoor OWC demonstrations have been reported over Fibre-Wireless-Fibre (FWF) link geometries [SHA14], [GHA13]. FWF laboratory experiments have achieved Tbps data rates using orbital angular momentum (OAM) multiplexing techniques and coherent transmission [WAN12], [HUA14]. Single-mode fibre (SMF) transceivers have typically been used, although multi-mode fibre (MMF) realizations have also been successful [CHE12].
Figure 1.10. Demonstrations of ultrafast infrared FWF links. The data rate is plotted as a function of the coverage area. The experiments in red used intensity-modulation direct-detection and those in black coherent detection. P is the transmitted power and OAM is orbital angular momentum.
Some research efforts have focused on enhancing the coverage area (Figure 1.10, points outlined in red). Wang et al. [WAN11] achieved a 4 x 12.5 Gbps link with a relatively large coverage are of >3m2 ; but the demonstration was not bi-directional and the receiver needed to be normally oriented to the incoming beam direction. Koonen et al. [KOO14] also designed a FWF link with a high data rate of ~37 Gbps.
However, the coverage area was below 1m2 and, again, the receiver had to be aligned normally to the incoming beam. Recently, UOXF in collaboration with University College London achieved both ultrahigh data rates (400 Gbps) and wide coverage [GOM15] and [GOM16] (see Figure 1.9, shaded region of interest). These demonstrations incorporated beamsteering units at both ends of the link with adaptive optics compensation were designed and implemented [GOM16b]. These are the fastest wireless links (RF or optical) demonstrated thus far, with practical indoor coverage.
WORTECS 18
Beyond the state-of-the-art The state of the art in this area are therefore point-to-point (P2P) links transmitting test data with some tracking and automated connection capabilities. Figure 1.11 shows the desired system, and to reach this research beyond the state of the art will focus on: - Design and demonstration of point-to-multipoint (P2M) architectures FWF with Tbps aggregate capacities. A base station in the ceiling communicates with several nomadic terminals lying near the floor of an indoor environment. - Seamless integration of FWF links to FTTH (Fibre To The Home) networks to achieve all- optical routing architectures. Further study on FTTH passive optical networks needs to be carried out to design a base station compatible with the FTTH protocols and wavelength of operation.

- New beamsteering techniques to improve the link coverage by achieving longer distances link to the Height (H) and wider Fields-Of-View (FOV). - Design and demonstration of an automated alignment system for P2M links with low latency, in order to satisfy mobile application requirements.
1.4.4 Hybrid networks State-of-the-art Figure 1.12 shows the evolution of Hybrid networks. An EC funded project, OMEGA, focused on Ethernet, WiFi and PLC (Power Line Communications) interoperability. The IEEE 1905.1 standard inherited the OMEGA concept and extended it to MoCA and other WiFi technologies in addition to other features including AP (Access Point) autoconfiguration, topology discovery and links metrics.
The aim of the ACEMIND [ACE16] project was to provide new functionalities such as path selection and traffic monitoring. The WORTECS project will focus on radio and optical wireless technologies offering higher throughput and lower latency.

Figure 1.12. Omega, IEEE and Acemind
The IEEE P1905.1 [P1913] working group aims to facilitate the usage of new services everywhere in the home and can be extended on mobile situation, by defining a unified framework for multi-interface devices as shown in Figure 1.13 below. During EconHome [KOR13] and OMEGA projects, the implementation of the convergence layer was performed using Linux. During Acemind project, the implementation of IEEE 1905.1 was performed on dLan hybrid plugs [KOR16] from the manufacturer Devolo.
Figure 1.13. IEEE P1905.1 interface with legacy technologies
Beyond state-of-the-art Current implementations of Layer 2.5 consider home technologies, such as Ethernet, WiFi, or PLC [P1913]. Therefore, these implementations do not need to support higher data rates that those of home networks. Among these, Gigabit Ethernet is the fastest technology, and it provides data rates up to 1 Gbps. In this case, the Layer 2.5 can work as software and still be fast enough to support all home networking technologies. For instance, the I-MAC implementation of Layer 2.5 based on Linux kernel needs about 7.5 microseconds to forward a single frame, and can support 1.5 Gbps data forwarding of 1400-byte long frames [KRA11].
WORTECS 20
In WORTECS project, we consider technologies eventually capable of Tbps transmission, and therefore the Layer2.5 must process frames transmitted so quickly. We will go beyond state of the art and investigate techniques to speed up the frame processing of Layer2.5 by 1000x, to support data transmission of 1 Tbps.
The major techniques we will investigate to improve the Layer2.5 beyond state of the art include parallel data processing, hardware/software codesign, and major improvements in the operation of networking protocols.
Since state of the art implementations of Layer2.5 are tailored for home networks, with data transmission only up to 1 Gbps, they can support such speeds with a simple serial frame processing. However, in future hybrid networks a single frame must be handled within a few nanoseconds, or less, and current hardware cannot support it. The major way to provide faster frame processing requires parallel processing, as depicted in Figure 1.14. In WORTECS we will examine the limits of parallel processing in software and hardware implementations of Layer2.5. Then, we will be able to answer the question if state-of-the-art hardware can support future hybrid networks, or where is the bottleneck that must be eliminated in future hardware design.
Figure 1.14. To support high-speed data processing the Layer2.5 must process frames in parallel.
The design of network protocols has also a great impact on the performance on frame processing in Layer2.5. For example, the use of long frames leads to a better performance than of short ones, as the Layer2.5 use almost the same time for processing long and short frames. However, longer frames are more prone to transmission errors, especially in wireless communication, and can degrade the performance. In WORTECS we will examine various how various protocol parameters impact high-speed data processing of future hybrid networks. We will select optimal setup of protocols and their parameters to integrate future terabit wireless technologies into a single network.
Finally, such high speeds of future wireless technologies require their tight integration to provide data transmission of 1 Tbps. Therefore, the part of Layer2.5 can be implemented in the Radio or Wireless Optics Transmitted Hardware, for example, in the baseband processor. All these integration aspects will be investigate during the WORTECS project.

2. Impact 2.1 Expected impacts 2.1.1 The expected impacts set-out in the work programme The WORTECS project is strongly contributing towards meeting the Work Programme 2016-2017 for Europe’s target “to maintaining and developing the technology leading edge in key areas such as electronics, photonics…or network technologies and systems”. The WORTECS project has the bold ambition of proposing “Innovation capacity …directed toward SMEs”. WORTECS project addresses H2020-ICT-09-2017 under the topic “Networking research beyond 5G”. The overall goal of the project is to design and develop key enablers for future beyond 5G systems, targeting the provision of ultra-fast internet services and applications to mobile users, including Virtual Reality and immersive experience as well as achieving ultra-low delay with locally based applications. Careful design of system and overall architectures aim at ensuring that the solutions, developed for mm- and optical wireless networks, that are robust, easy to deploy, low cost and energy efficient while offering to users an incomparable quality of experience. These specific foreseen impacts of WORTECS, as quoted in the Expected Impacts section of the Work Program, are summarized below.
Impact 1: Validation of disruptive communication concepts, technologies and architectures. WORTECS will propose new communication concepts by using mm-wave and nm-wave (optical) Proof of Concept systems combining radio and optical wireless technologies. These PoC will implement new technologies (Wireless Fibre) and architectures (Hybrid Network) capable of providing terabit per second capacities.
Impact 2: Proof of applicability of challenging spectrum regions towards innovative and cost efficient applications. WORTECS will address the issue of using mm-wave and optical links that require pointing and tracking and other measures to create reliable communications. The consortium will explore frequency bands above 90 GHz by developing hardware real-time prototypes able to operate (typically at 240 GHz for the radio part and in nm-wave band (Optical band) for optical part; highly bidirectional communication links will be designed in order to allow for a huge improvement in spectrum spatial re-use. Advanced schemes for cooperation between optical and radio systems will enable higher user data rate and QoS regardless of user mobility, cost efficient and location.
Impact 3: Advances in signal processing and information theory and scientific publication in world class journals. WORTECS will design novel radio and optical wireless, including for example new RF front-end and new antenna design and potentially new MAC structures (including link adaptation and framing) following a “clean-slate” approach, with, for instance, the objective to minimize the latency (target : <1 ms) by appropriate frame structure design and reducing overheads. Tracking capability will be improved with optic power level analyse for optic prototype and Time-Of-Flight (TOF) measurements for radio prototype.
Impact 4: Industry competitiveness with exploitation of academic research through transfer and innovation towards industry, in particular SMEs or start-ups.
WORTECS 24
The EC has acknowledged leadership in VLC, with world leading results from UOXF and collaborators and world leading SMEs (Oledcomm and PureLiFi). VLC (LiFi) is estimated to be a $75Bn market in 20231. WORTECS will give OLD and PLF access to the PoC demonstrations, as well as operator ORA, and allow them to develop the first Gbps capable products available worldwide, whilst understanding the needs of the operators of such systems. Further ORA has links to device manufacturers, allowing their needs to be understood. The EC also has sustained leadership in high-frequency radio and WORTECS will allow partner IHP and BCM to strengthen its expertise in this area. Virtual reality (estimated to be a $40Bn market worldwide in 20202) will be a key application area in the future and the inclusion of BCM allows partners to understand the needs of this application and gain a leading position.
WORTECS will therefore directly improve the competitive position of SMEs OLD, BCM and PLF, Operator ORA and VR expert BCM. Indirectly it will reinforce EC leadership in VLC and high-frequency radio and wider 5G technology. The availability of high speed infrastructure will also impact SMEs especially in the field of games (estimated to be a $23.5Bn market across Europe and $100Bn worldwide in 20163) and indoor simulators.
2.1.2 Impacts on standards WORTECS partners ORA and PLF are directly involved in standards processes and have the necessary contacts and expertise to ensure that the new concepts developed directly influence this process. PLF are actively involved in the revision of the major LiFi standard IEEE 802.15.7r1, and ORA are involved in both IEEE 802 and 3GPP efforts. WORTECS will thus have direct influence on current standards, and through tutorial presentations will influence future Beyond 5G standards and the directions these will take.
2.1.3 Impacts on innovation capacity and competiveness of partners The innovation capacity of WORTECS partners is guaranteed by the university/research centers in the consortium, while result exploitation and competiveness is guaranteed by SMEs in the consortium. WORTECS will also provide operator ORA with realistic and quantified assessments of the maturity of the different technological subsystems in radio and optical wireless. Such ‘future looking’ knowledge is extremely valuable to the long term competitiveness of ORA, as it will be able to plan future product evolution from an expert point of view. Section 2.2.4 (Exploitation) presents the results and solutions expected to be implemented in future products and services. WORTECS aims at a substantial two-orders of magnitude increase in data transmission rates for VLC. This will enable OLD and PLF to offer world-leading products, significantly enhancing their competitiveness.
2.2 Measures to maximise impact a) Dissemination and exploitation of results The WORTECS consortium will develop well-scheduled and clearly targeted dissemination activities to obtain high impact. For instance, during the first 12 months following the start of the project, B-COM will present a WORTECS project paper presentation to ICCSP 2018 (http://waset.org/conference/2018/06/toronto/ICCSP ) and VRST 2018
1 https://www.gminsights.com/pressrelease/LiFi-market 2 Virtual Reality Industry Report 2016, SuperData 3 https://newzoo.com/insights/articles/global-games-market-reaches-99-6-billion-2016-mobile-generating-37/
WORTECS 25
(http://conference.researchbib.com/view/event/62367 ). Orange will present a WORTECS project paper to WWRF (http://www.wwrf.ch/), IFIP and SPIE Optics and Photonics (https://spie.org/conferences-and-exhibitions/optics-and-photonics ). The University of Las Palmas schedules presentations at ICAWOC, ICC 2018 and CSNDSP 2018. This is scheduled by a tailored dissemination plan for each year of the project. Year 1: priority is to promote visibility of the project and the objectives. The focus is on conferences mentioned above and the web site indicated here after. Year 2: increase visibility into standardization bodies, for instance IEEE 802.11, with a presentation of WORTECS first results. An open event, focusing on PoCs presentation will be held by B-COM in France. For this, WORTECS will invite industry with interests in the area of Virtual Reality, including device manufacturers (such as HTC, Samsung, Nokia…), and representative of applications sectors (for instance Aerospace, Healthcare, Automotive, Communications). Year 3: WORTECS results will be presented to globally significant conferences, for instance, SPIE, ECOC, GIIS, ICC, Globecom. We will also target end users in the Virtual Reality industry including for example Laval Virtual, as well as presentations at the Paris Games Week. We will hold a second open event, showcasing the Tbps demonstrations. For this final Open Event, WORTECS partners intend to invite representatives from all aspects of communications, from chipset manufacturers to SMEs to end users from a broad range of applications sectors. We will also target key academics, in order to influence future academic research and create the foundations for further research proposals.
2.2.1 Dissemination to standards bodies Contributions will be submitted to standardization bodies by consortium partners who are already long-term and active members of these organizations, such as Orange and PureLiFi. For instance, Orange currently contribute to IEEE 802 (including IEEE 802.11ax and ay groups) and will follow activities in IEEE 802.15.7r1” and IEEE 802.11 NWG (Wireless Next Generation) groups. PureLiFi will build upon the results from the project to participate in the definition of the related standardization specifications such as 3GPP-Rev. 15, IEEE 802.15.7r1, IEEE 802.11 and others standard such as ITU-T G.hn. Contributions will be elaborated in WORTECS by the respective technical work package and task, and will be coordinated by WP5. Currently we envisage the following standards to be relevant: IEEE 802.11 o ax: successor to 802.11ac. The Task Group (TG) goal is to increase the throughput efficiency (4X), o ay: new physical layer in 60 GHz millimeter wave spectrum, o WNG Study Group (SG) is focused on Wireless Next Generation activities. This SG could include radio and optic band PHY/MAC Layers. IEEE 802.15.7r1: This recent Task Group (TG) works on short range optical wireless communication with additional spectral band (visible, infrared and ultraviolet wavelengths) and new features (Optical camera Communication on smartphone, LED Identification and Light Fidelity). ITU-T G.hn: International Telecommunication Union Standardization sector focused on home networking specification with data rates up to 1 Gbps. 3GPP: 3rd Generation Partnership Project is collaboration between groups of telecommunications associations to propose a global mobile solution, for instance 5G standard.
WORTECS 26
2.2.2 Dissemination to research community In terms of dissemination of research results WORTECS targets the conventional channels including high quality journal papers, conference papers, networking and the internet. The beneficiaries are confident that the quality of the proposed work includes a substantial potential for publication in international journals with peer review. The consortium intends to achieve 10 peer- reviewed publications during the lifetime of WORTECS. All the publications will include an acknowledgement of the funding scheme. WORTECS partners have already defined some conference linked to the WORTECS objectives: ICCSP: International Conference on Communications and Signal Processing, VRST: ACM Symposium on Virtual Reality Software and Technology, ICAWOC: International Conference on Applications of Wireless and Optical Communications, ICC: IEEE International Conference on Communications, CSNDSP: International Symposium on Communication Systems, Networks and Digital Signal Processing, WWRF: Wireless World Research Forum, IFIP: International Conference on Performance Evaluation and Modeling in Wired and Wireless Networks, SPIE: the International Society for Optics and Photonics, Globecom: IEEE Global Communications Conference
2.2.3 Management of knowledge, IPR and other related activities The general rules and regulations concerning the management of knowledge will be set forward in the Consortium Agreement to be signed between WORTECS participants. They will follow the general guidelines of the Model Contract for Framework Programme 7 projects. The strong interaction between WORTECS partners requires that appropriate arrangements on Intellectual Property Rights (IPR) be in place. This means that best practices in IPR management have to be established based on factual aspects of the WORTECS project. IPR will be generated within the Work Packages (WPs) and the ownership will be as set out in the consortium agreement. IPR development will be reported by the Work Package (WP) leader to the Project Management Team (PMT) and General Assembly (see section 3.2.1) will ensure that the overall approach is coordinated across the project. This will ensure a strong framework, which allows both protection of IP and widespread dissemination to external bodies, as set out above.
b) Communication activities WORTECS consortium partners are committed to pursuing effective communication of the project results and spending effort on raising awareness about the initiative among scientific and technical stakeholders, industry, policy makers and the general public. The consortium will: Organize two workshops at WORTECS events. Publish at least 10 papers in high-impact conferences and/or journals (when possible journals with an open access publication policy will be prioritized). Showcase and demonstrate project results at least at one international meeting, e.g., annual European Conference meeting or address the community of Video Game platforms, for instance Laval Virtual (http://www.laval-virtual.org/en/ ) or Paris Games Week (https://www.parisgamesweek.com/ ).
WORTECS 27
Create public website at the very beginning of the project (available in the first quarter), in order to make visible the project and its achievements. Create promotion movie on Youtube, targeting online social media communication platforms for the public, and will also target LinkedIn and Research Gates to communicate with professional groups. Contribute to the networking and coordination events organized by the European Commission. Create an overview flyer of WORTECS as soon as the project starts. This document will be made public on WORTECS website and will be distributed during events and exhibitions to which WORTECS will participate.
Publication of WORTECS results in at least 10 papers in peer-reviewed conferences and/or journals. A representative example that will be targeted by WORTECS for dissemination is provided below: Orange will disseminate results from WORTECS project in publications in international journals (such as IEEE Optic and Photonics or Transactions on Communications), magazines and conferences (SPIE, Globecom, etc.). Orange will also disseminate the outcomes from WORTECS internally through internal publications and internal annual research exhibitions event (beginning of December each year). Oledcomm will use different dissemination media to promote this technology, it take advantage of being part of Smart Lighting Alliance. This and other dissemination channels such as television and internet will permit Oledcomm to consolidate in the market. For B-COM, exploitation results will be presented in conferences and during workshops. B- COM is involved in standardization activities in ETSI and in open source communities like Open Air Interface, and will use these links to disseminate WORTECS results.
2.2.4 Exploitation of the results Orange Exploitation Plans Orange is currently rolling out 4G networks and will continue to invest in this technology. Orange is also involved in 5G research (including 5G PPP projects), standardization (3GPP) and trials activities (including a partnership with Ericsson: “Technology building blocks, proof of concepts, and pilots across Europe allowing Orange to experience 5G services and capabilities from 2017 onwards” - https://www.ericsson.com/news/2047172).
In parallel it is also important for Orange to be prepared for Beyond 5G technologies. WORTECS will provide Orange with key information on: - Spectrum bands above 90 GHz for which a real potential can be identified in terms of availability and performance; these outcomes will give information to promote or prioritize bands in upcoming World Radio Conferences; - Requirements: those agreed within WORTECS will constitute initial figures that can be further refined and discussed within organizations like NGMN (Next Generation Mobile Networks), ITU (International Telecommunication Union) or 3GPP when future wireless generations will be defined; - Key building blocks suitable for those bands: when and where relevant, these identified technologies can be proposed and promoted by Orange within future standards covering >90 GHz spectrum; - Prototypes: the proofs of concepts developed by partners within WORTECS will demonstrate the feasibility of the technological choices; the platforms can then been used by Orange to demonstrate to its usual RAN vendors the relevance of the solutions
WORTECS 28
developed in the spectrum bands chosen, in order to convince an enlarged audience and develop an ecosystem around WORTECS solutions. Olecomm Exploitation Plans Currently, Oledcomm is succeeding in the wireless optical communications market by offering geolocation products. Oledcomm has also started the development of high rate transceivers for internet applications and supplied them to hospitals. Nevertheless the necessity of a very-high data rate platform is clear; the market is expecting optical wireless solutions and approaches to achieve much higher data rates. The expected results will enable Oledcomm to provide clients with high-rate data transmission, for smart cities and indoor applications. Even more, the WORTECS technological benefits will permit Oledcomm to envisage new products because several blocks, from front-end optics to PHY and MAC layers will be ready to use and/or experience in designing them will permit Oledcomm’s engineers to redesign new products. Through internships, Oledcomm will participate in the preparation of PhD and engineering students that, once their diploma obtained, can join Oledcomm as highly qualified personnel.
B-COM Exploitation Plans B-COM is actively researching and developing technology software blocks/ingredients with the objective to increase the data throughput (5G and B5G). In WORTECS, B-COM aims to value advanced research topics on wireless radio transmission with the goal of proving their feasibility by HW developments and implementation (flexible RF front-end and fast reconfigurable radio/optics digital IPs modules for instance) as well as SW developments (software simulation platforms). As an SME, the main objective is to propose new products and services to customers. B-COM aims also to gain commercial value from its own experimentation testbeds and platforms, especially in virtual reality use-case by promoting wireless video transmission at very high data (4K or 8K) allowing B-COM to promote its expertise in new video formats.
WORTECS will also enable B-COM to enrich and broaden its contributions, especially in the area of M-MIMO. B-COM has also a role to play in helping the education of future engineering students and will use WORTECs technologies as a case study.
Pure LiFi Exploitation Plans PureLiFi is currently rolling out the first LiFi enabled fully-networked mobile dongle. In parallel, the company is involved in 802.15.7r1 standardisation activities. The WORTECS project is the place to benchmark and select technologies and architectures for future standards and high- speed connectivity enabler devices to achieve multi-Gbps performance. This selection is key for PureLiFi to ensure that future optical wireless communication devices can be realized using cost- effective technology capable of delivering the necessary performance and will enable LiFi to become an integral part of beyond 5G network connectivity. The WORTECS project will allow the company to take part in hybrid system development; deployment and testing that would otherwise be unreachable to PureLiFi due to the required critical mass for its realization.
The WORTECS project is seen as a unique opportunity to share and evaluate with the main actors in the industry and academia the most promising concepts and techniques for future optical wireless communications. PureLiFi will use the results from the WORTECS project to benchmark and better characterize the performance of existing high-speed wireless connectivity technologies, providing a clearer view on their merits, limitations and potential for performance improvement through hybrid networking.
WORTECS would be a key de-risking process for key developments in optical wireless communications that PureLiFi may eventually use as part of its commercial activities. Specifically,
WORTECS 29 the use of precise indoor location focused high data rate solutions and fast handover between lights are areas that have seen significant interest from PureLiFi customers.
University of Oxford Exploitation Plans UOXF has a strong track-record in exploitation of results from research. Oxford University Innovation (OUI) is the technology transfer organization of the University, which has spun out more than 20 companies from the Department of Engineering Science, where the work in WORTECS will be undertaken. Prof O’Brien holds 8 patents and applications, one being commercialized at the moment. Results from WORTECS will be assessed, and patented, if of commercial value, using the Universities existing mechanisms. Wide academic dissemination will also open up other opportunities for exploitation in areas such as wireless data centers, wireless aircraft cabins, and other areas where high bandwidth data is required, and we will pursue research programs in these areas.
University of Las Palmas Exploitation Plans As a public academic institution, his main exploiting results are obtained through supporting scholarship PhD and MS programs, in which WORTECS will provide a valuable experience not only in research and implementation of wireless systems, but also in the active collaboration with other academic institutions and companies. It will also support research activities in an ultra- periphery region of the UE as the Canary Islands. ULPGC can provide to the partners their research facilities and instrumentation, and also his previous works on channel estimation and location systems.
IHP Exploitation Plans IHP is a publicly funded Research Institute with a focus on exploiting research results both academically and economically. IHP will exploit the WORTECS results academically through the annual summer school, lectures given at Universities in Berlin and the graduate school supporting PhD students at IHP. Furthermore, IHP will make the developed chips available to project partners and market the developed Intellectual Property (IP). In addition to this, a spin-off company focusing on the development of high-speed wireless transceivers at 240 GHz will be considered. The developed techniques for hybrid networks are applicable to other applications and can be marketed as independent IP.

3. Implementation 3.1 Work plan — Work packages, deliverables To address the project objectives, WORTECS will be organized using a flat project structure with parallel activities taking place in different work packages. The work packages will be further divided into task, wherein specific research will be performed on selected topics.
The WORTECS work plan is structured into five work packages, as shown in Figure 3.1; three of technical nature, one for project management and one for dissemination/standardisation activities. The spectrum studies and scenarios and uses cases will be defined in WP2. These elements will give the baseline for system studies, including definition and selection of building blocks, via simulation and modelling, undertaken in WP3. Specifications coming from WP3 will drive the PoC developments, development of building blocks, integration, tests and validation for two prototypes on radio side and two prototypes on optical wireless (four prototypes via two demonstrators or PoCs). All the results of the works will be disseminated to the community and potentially shared in standardisation bodies; this will be undertaken in WP5.
The WORTECS work relies on close collaboration between the work packages and their tasks. In particular, the work of WP3–4 needs and will of necessity have to be carried out with tight synchronization and collaboration. The timing of the different work packages and their components are illustrated in Figure 3.2.

Objectives The main objective of this work package is to define the use cases and related requirements that will drive the theoretical studies and implementation work of WORTECS. In order to be as efficient as possible for simulations and implementation work, three main steps are identified: 1. Overview of already identified use cases in the higher part of the spectrum (State of The Art analysis) 2. Sub-selection of three to five use cases more relevant for bands above 90 GHz and in terms of expected business for the members of the consortium; requirements (key performance indicators + values) will be associated to these use cases in order to drive theoretical studies 3. A single use case (and requirements) will be prioritized for implementation (with a virtual reality application as an initial selection). Prior to this core activity of WP2, a survey of the spectrum above 90 GHz in Europe will be undertaken, in order to prioritize, within WORTECS, the bands that will be used for simulation and implementation purposes. Figure 2.1 below presents the way WP2 will interact with other work packages of WORTECs.

Description of work WORTECS 38
Task T2.1 : Spectrum: THz band overview (M1 to M3 + M31) Lead partner: ORA Participants: PLF A survey of the spectrum above 90 GHz in Europe will be undertaken based on World Radio Conference 2015 outcomes and individual countries regulation. The World Radio Conference 2019 will take place from Oct. 28th to Nov. 22nd (2019); the WORTECS deliverable on spectrum will then be updated accordingly, if required. This task (and WP2) will be put in sleep mode between M4 and M30.
ORA will contribute to the status of spectrum above 90GHz in Europe. PLF will contribute to the status of spectrum between 10,000 nm and 200 nm in Europe. This will include basic eye-safety considerations and potential emission health risks.
Task T2.2: Use cases, requirements and business perspective (M1 – M3) Lead partner: ORA Participants: OLD, PLF Many existing collaborative projects, e.g. mmMAGIC4, MiWEBA5 MiWAVES6, or standardization initiatives, e.g. inside 3GPP7, have identified potential use cases in higher bands spectrum (up to 100 GHz) targeting 5G. In parallel, THz spectrum potential has been investigated as well in collaborative projects (iBROW8, TERAPAN9) while generating interest on standardisation side (IEEE 802.15 IG THz10, IEEE 802.15.711). These multiple sources will be analysed by the WORTECS consortium in order to establish a landscape of use cases relevant for THz spectrum. A sub-selection of 3 to 5 use cases will then be undertaken to define guidelines for theoretical studies, covering diverse environments, including indoor and outdoor situations. Once use cases have been identified, related requirements, e.g. in terms of capacity, throughputs, coverage, latency … , will be agreed between the partners based on inputs from e.g. 3GPP, IEEE, NGMN12 or ITU (IMT-2020 requirements as defined by ITU will be published mid-2017).
Thanks to its involvement in 5G PPP projects, in standardization (3GPP), inside operators’ alliances (NGMN) and in international initiatives (ITU), ORA, as a mobile operator, will contribute on the definition and prioritization of use cases, and to the definition of their related requirements. OLD contribution relates to the selection of use cases based on its impact in society, and public promotion. PLF will contribute specific use cases and a more detailed illustration of how these use cases could be beneficial from a business perspective. In addition, PLF will provide specific system performance requirements which stem from and enable the presented use cases.

Lead partner: BCM Participants: OLD, PLF For the sake of implementation work, a single use case, likely to be linked to augmented reality (AR) or virtual reality (VR), will be proposed to WP4, at the beginning of the project. To drive the implementation, this task will focus on providing WP3 and WP4 with specifications dedicated to a multi-user VR or AR platform based on business, technical and acceptability studies to justify the soundness of such a choice. Indeed, the commercialization of the first mass market VR headsets (Oculus, Vive, PSVR, etc.) and the development of augmented reality devices (Tango, Hololens, etc.) suggest the democratization not only of consumer market use cases, but also and mostly of professional use cases (learning, design, telepresence, etc.); such use cases will involve a large number of collaborative users requiring high quality contents that will be displayed on devices, with a very low latency (motion-to-photon13 latency), whether these contents will be rendered distantly or on the device itself. This task will deliver a study evaluating, for a set of relevant VR applications, the optimal trade-off between quality of experience (physiological and psychological acceptability), technical feasibility, and deployment as well as operating costs to ensure the economic viability of the system.
Figure WP2.2 – Example of a multi-user virtual reality system requiring very high bandwidth wireless solution with a very low latency.
Once the proof of concept will be available, “user acceptance” tests will be undertaken in order to check if the impact of the technologies implemented is acceptable. Results of these user tests will drive the implementation of the final platform.
BCM will look at relevant VR applications and will contribute to the study aiming at ensuring the economic viability of the system. Moreover, BCM will experiment the first version of the VR platform. OLD will assess the optics and Hybrid Network use-case business model. PLF will look at the application of the VR technology to various environments and the potential to develop viable business models.

Objectives: The main objective of this work package focuses on the definition of new communication systems based on high frequency radio (> 90 GHz) and optical wireless communications (based on VLC, laser, Infra-Red …) for multi-Gigabits transmission. The cooperation/aggregation between different Radio and optical Wireless Access Technologies (WAT), leading to the design of a specific Hybrid Networks architecture, will allow these to achieve Terabit transmission rates. The main issues to be addressed in order to achieve these objectives are the following:
Technological specifications of Multi-Gigabits radio and wireless optics for virtual reality use-case; Mutualisation of common Gbps radio and optics analog and baseband processing for transmitter complexity decrease; Hybrid Network architecture design for wireless terabit transmission; System modelling and performance evaluation in terms of throughput, latency, positioning, capacity, coverage.
Firstly the system definition will be addressed for a virtual reality use-case but diverse set of services, including mixtures of services will also be considered. The WP3 has strong links with the WP2 since the system definition should take into account the requirements issued from the different use-cases and also WP3 will serve WP4 as inputs for specifications to the Hardware (HW) design and implementation.
Description of work: This work package is divided into two tasks. Each task containing several sub-tasks, described in the sub-sequent text paragraphs. The different sub-tasks naturally have some dependencies as listed under the same work package.
Task 3.1: Gbps radio and Gbps Optical Wireless Communications (OWC) for Virtual Reality transmission (M1-M15) Lead partner: ORA Participants: OLD, BCM, PLF, UOXF, ULP, IHP. Task 3.1 will focus especially on virtual reality use-case transmission on the following items: WORTECS 42
Specifications and performance evaluation of a Gbps radio system (radio analog/digital and baseband processing) Specifications and performance evaluation of a Gbps OWC system (optical/digital and baseband processing) Common Gbps radio and OWC architecture modem definition with control selection.
WP3 will design the wireless radio and OWC Physical Layer system based on the input from WP2. This will include all elements of the transmission chain, including all the digital baseband processing (coding, modulation, link adaptation, framing, detection, estimation …) and the radio and optical front-end parts (antenna design, impairments, ADC/DAC, amplifier, filters,). Positioning and tracking is very challenging especially in Virtual Reality use-case. For the radio PoC WORTECS will enhance the performance of positioning/localization methods using standard radios (2.4 GHz, 5 GHz, 60 GHz, UWB) whereas for the OWC PoC localisation can be provided using the tracking systems required for the line of sight Optical links.
Downlink and uplink will be considered, especially considering the asymmetry in data rates. First P2P system performance evaluations will be carried out to make sure the virtual reality requirement is achieved. For system performance modelling, WP3 will adapt propagation channel models already used by partners, including for radio at high (and very high) frequencies (typically up-to 240 GHz) and OWC transmission. Close collaboration between T3.1 and T3.2 will allow models and results to be shared between tasks if relevant.
A decision matrix listing all the potential components will be carried out in order to select the main elements that will be implemented in WP4. Of course, radio and optics system component selection and specifications provided to WP4 will take into account complexity evaluation and HW implementation feasibility (taking into account the platforms capabilities and the amount of resources dedicated to the HW implementation). Iterations between WP3 and WP4 will lead to a final specification.
After defining each radio and optical system, collaborative work will be to converge as much as possible towards a flexible Radio Frequency (RF) and baseband architecture leading to transmitter complexity decrease. This radio and baseband architecture will take into account Hybrid Network studies concerning the control that has to be applied for selecting/aggregating different radio/optic interfaces leading to high system flexibility. The controller location is one of the key aspects to be studied. This middleware can be defined in several ways, even in the application layer. It has to be studied for answering to specific criteria (latency, throughput, power consumption …). A similar analysis will be also performed to understand how the optical and radio front-ends might be combined. The outputs of the T3.1 will be technical reports and also link level simulators.
Task 3.2: Terabits system definition (M1 – M37) Lead partner: UOXF Participants: ORA, OLD, BCM, PLF, ULP, IHP. To achieve Tbps transmission, task 3.2 will focus on the following items: Advanced radio and OWC system studies (PHY and MAC layers) and performance evaluation Advanced Hybrid Network system architecture studies allowing to achieve Tbps communication Integrated Tbps wireless network architecture evaluation WORTECS 43
Advanced research studies about PHY and MAC layers and Hybrid Network architecture will be carried out in parallel during this task. Results will lead to definition of the Tbps system architecture. Different use-cases will be considered in the evaluation. All these studies will be simulated for performance evaluation by using either radio or optics simulators. Channel modelling based on ray-tracing for radio and optics will be implemented and Front-end impairments will be considered for performance evaluation. Performance will be defined following different metrics such as: QoS (EVM or BLER), capacity, link budget or coverage.
This task aims at providing inputs to the WP4 for Terabits system implementation. At M24, a selection of the enablers/components that will be potentially implemented in WP4 for the V2 HW demonstrator will be undertaken. WP4 will implement a suitable subset of these enablers, which show the key features of Tbps transmission.
Partners will contribute to each aspect of these studies as follows: PHY Layer High throughput and low latency coding schemes such as LDPC codes or block codes with soft decoding (BCM); Digital or analog (or hybrid digital/analog) MIMO/beamforming/beamsteering technique either for radio or OWC. Transmission with multi-radiated elements allows to increase the data throughput, to increase the coverage or to decrease the radiated power. By applying specific processing to the antenna/LED/laser array, the signal is focused in a specific direction optimizing the link budget of the transmission while minimizing the interference between users. However, MIMO studies have to be done about: o Integrated radio and optics front-end design (IHP, BCM, OLD, PLF); o Modelling of impairments between antenna/LED/laser array elements (UOXF, IHP); o Novel optical concentrator, optimizing the bandwidth (BW) and the Field Of View (UOXF); o Radio and optics baseband processing methods (MIMO precoding methods (BCM) , channel estimation (ULP), synchronization (IHP, OLD, PLF) ); o Multi-User (MU) MIMO transmission (BCM). Multi-Carrier modulation such as OFDM or new prototype filters such as FBMC for better frequency localization optimizing the spectral efficiency for resource allocation in multiple access scheme such as OFDMA or Wavelength Division Multiplex (WDM) (UOXF, BCM, PLF); Advanced radio and optical receivers using equalization technique for ISI compensation (IHP); Very accurate geolocation process for tracking (IHP, UOXF, OLD).
MAC layer Establishing the requirements according to the IEEE 802 (802.2, 802.11 and 802.15) to obtain radio-optics connectivity (OLD, IHP and PLF); Setting MAC layer requirements that permits to work under multiple IEEE 802 (.7, .11,.15 etc) protocols. These requirements take into account roaming, handover, and multi-access for multi-user/services resource allocation (OLD, IHP and PLF); Defining required MAC signalling issued from PHY layer that permits to work with multiple IEEE 802 ( .7, .11 or .15) protocols. (IHP)
Hybrid Networks New architecture definition. Indeed, to reach the Terabit/s transmission, aggregation of
WORTECS 44
several wireless access technologies is proposed (multi-connectivity from low frequency band to very high frequency bands). This aggregation needs that the technologies cooperate and are controlled by a “centralized” master (IHP); Multiple radio and optical wireless interface management in multi-user transmissions (IHP, ORA); Definition on metrics selection to manage the different technologies (based on current link quality, current traffic, traffic requirements etc.); (ULP, BCM, IHP) Interaction with the MAC layer for handover, multi-services and multi-user management (IHP, PLF) ; Evaluation of the controller at Layer 2.5, just above the MAC layer as in the standard IEEE 1905.1. that needs to consider hardware accelerators located directly in the PHY layer of radio or optics hardware (PLF, IHP); Study of error recovery schemes realized in Layer 2.5, tailored for wireless links; (IHP) Definition of new protocols (or usage of common Ethernet); (IHP) Compatibility with PON for backbone interface connection (UOXF); All optical communication architecture ; (UOXF) Study of fast packet forwarding between several heterogeneous wireless technologies, mainly wireless radio and optics (IHP).
The outputs of the T3.2 will be technical reports, system model and simulations.

Objectives: The main objective of this work package focuses on the final integration of a new communication system based on high frequency (HF) radio and Optical Wireless Communications (OWC). The resulting prototype will be capable of establishing cooperation/aggregation between different Radio and Optical Wireless Access Technologies (WAT). Advanced hybrid network architecture, will allow achieving high data rate Terabit transmission. Close collaboration between WP3 and WP4 will define the hardware design, the integration methodology that will lead to the final prototype integration: Optics, Radio and advanced hybrid network.
Two demonstrators or PoCs will be created. A first demonstrator will provide a multi-gigabits virtual reality transmission by implementing a wireless optic and a mm-wave radio system. The second demonstrator will target Terabits communication, addressing different use-cases, and will be provided by aggregating several optical wireless and radio systems via a high speed hybrid network controller. WP4 will evaluate the performance of both these demonstrators.
Description of work: This practical realisation work package is divided into the following tasks. The first one will focus on the multi-gigabits downlink/uplink virtual reality transmission; a PureLifi and Oledcomm prototype providing Optical Wireless Communications (OWC), and a prototype by IHP providing radio communications will be implemented. The second task targets the terabits communication, addressing different use-cases. The University of Oxford (UOXF) will deliver OWC using wireless fibre techniques IHP/BCM will provide a radio prototype.
Task 4.1: Gbps radio and Gbps optical wireless communications for virtual reality transmission (M1-M24) Lead partner: PLF Participants: ORA, OLD, BCM, ULP, IHP. This task addresses the virtual reality use-case, which requires several Gbps transmission in downlink, whereas only few kbps are required for the uplink. B-COM will provide an existing virtual reality platform (environment, video content, equipment like high speed PCs, caves, helmets) that uses a wired connection. WORTECs will replace this wired connection with wireless.
WORTECS 46
Two demonstrators will be developed in parallel in tasks 4.1 and 4.2 to achieve these high throughput wireless links. This first demonstrator will combine both wireless optic and radio modems that will be interconnected for switching. Then this first demonstrator represents a multi- Gbps transmission capacity and coverage inside the envisaged environment suitable for the virtual reality use case (prototype Oledcomm/PureLifi and prototype IHP). The wireless optical system consists of a diversity configuration comprising up and down transceivers with seven transmission points for instance, each delivering a 1Gbps rate, while the radio system will use 2 radio streams (at maximum) with very high speed DAC/ADC and high bandwidth (at least 5 GHz). As VR depends on high accuracy geo positioning, Oledcomm and IHP will contribute to tracking by proposing and developing accurate methods to achieve this.
In the Task 4.1, the OWC system will be developed by Oledcomm and pureLiFi. The optical wireless demonstrators designed by Oledcomm and PureLiFi will allow communication between a ceiling transceiver and a mobile transceiver linked to a smartphone or HMD. The most suitable implementation will be investigated and delivered as part of this task. The Access Point (AP or ceiling) module is an array of individual transceivers in a diversity configuration, it is constituted by: 1. A newly designed optical front end element capable to amplify the incoming radiant flux into a photodetector (PD) to take the PD to its response time. 2. Analog signal amplification, equalisation and digital to analogue/analogue to digital converting of the signal in both cases: uplink and downlink at gigabit per second rates. 3. Modulation/demodulation, QAM mapping, multiplexing, framing, error detection and correction. 4. Integration and internal tests of the optical wireless demonstrator.
The final prototype will include geolocation capabilities managed locally or in the internet cloud. For instance, Oledcomm will equip each Tx to enable the tracking a mobile device with a resolution of better than 20 cm. Oledcomm and PureLiFi will collaborate on the delivery of this prototype. Oledcomm will work on the design of Tx/Rx front end optics and PureLiFi will provide the OWC PHY/MAC management in multiuser scheme.
The radio prototype will use existing hardware, either from IHP or BCOM. The choice will be made according to the virtual reality requirements and the performance of the platforms, and may include a combination of the two. The digital baseband processing part will be developed in VHDL and implemented in an FPGA component. For the first version of the radio prototype, a data rate up to 20Gbps will be targeted in a point-to-point transmission (with one single data stream). The platform and the system should be capable of integrating a mm-waves radio front-end with one or more antennas including high speed DAC/ADC, accurate local oscillators, analogue filtering, power amplification and one (or more) powerful FPGA for the integration of the baseband processing, including the modulation, the mapping, the framing, the channel coding and advanced detection techniques for the reception part. The objective is to update the current IHP baseband part to increase the data throughput by parallelizing the baseband treatments. A particular attention will be also carried out about the implementation of tracking methods because virtual reality use-case needs very accurate user’ location position. So, bidirectional transmission is mandatory and will be also implemented in the radio system. Efforts and knowledge of different variants of Time of Flight (ToF) measurements will be applied for radio wireless communications or positioning/localization.
To aggregate the wireless optical and radio systems, Hybrid Network controller will be implemented either at the MAC or RLC layers. Updates of some existing systems (IEEE 1905 or others) will be considered for implementation as well as of-the-shelf approaches such as fast optical WORTECS 47 switching using an Ethernet protocol.
Integrators and partners involved in the prototypes implementation will work closely with WP3 to ensure that system complexity and choice of components can be made carefully, and that the PoC systems are implemented with minimal complexity, given the challenging targets.
In parallel with the design of the wireless optical and radio systems, collaborative work will ensure that common functionalities can be used for both wireless optical and radio transmission (ULP, BCM, ORA, OLD, IHP and PLF). This will enable a common and flexible radio and baseband architecture leading to a transmission complexity decrease. Then, the flexibility will allow a fast reconfiguration of the system that could be able to switch between wireless optical and radio transmission. The reconfiguration will be managed by middleware that will select the appropriate system according to specific criteria, as latency, throughput, and power consumption.
The output of the T4.1 is a VR use-case with a common multi-gigabit millimetre waves radio and OWC architecture with control selection (Proof of concept deliverables D4.1 to D4.4, listed here below).
Task 4.2: Terabit system (M1 – M38) Lead partner: UOXF Participants: ORA, BCM, IHP. To achieve Tbps transmission for a whole system, and following task 3.2 goals, T4.2 concerns prototyping. - A first Optical wireless fibre communication network to provide terabit aggregate capacities in indoor environments.
- The University of Oxford will implement a Tbps capable system that uses beamsteering to direct light from a fibre through free space to another optical fibre then on to a terminal. Bidirectional communications and operation at 400 Gbps has been demonstrated with such an architecture, and the focus here is the creation of a point-to-multipoint system that is compatible with next generation PONs. The system also provides high precision (several cm) positioning information for terminals within the coverage area using a beacon based tracking system, and the use of this for virtual reality applications will be investigated.
- An advanced radio platform. IHP will develop a 240 GHz radio frontend with beamforming capability. For this purpose the IHP SiGe BiCMOS technology will be used. The target baseband signal bandwidth is 25 GHz. The integration of on-chip antennae is planned. For increasing the gain and improving the link-budget, hybrid beamforming is targeted. The front-end chips with antennae will be integrated on a frontend module. To further increase the gain, dielectric lenses may be used. The target data of 500 Gbps, will be reached with several spatial streams. This is equivalent to a spectral efficiency of 10 bps/Hz over all four streams or 2.5 bps/Hz per stream. For the demonstration of the performance, standard high-performance lab equipment will be connected to the RF- frontend module. The demonstration will be performed using a hardware-in-the-loop approach. At IHP very high bandwidth Arbitrary Waveform generators (AWG) and vector signal analyzers (VSA) are available for this purpose. Specialized modulation and coding schemes as well as MIMO processing algorithms will be developed in MATLAB. The transmit/receive data will be generated/processed on a high performance PC connected to AWG/VSA, using MATLAB. Experiments in realistic environments linked with the
WORTECS 48
targeted use-cases will show the performance of the developed algorithms and RF-module. Using a time-stamp approach for the transmitted and received packets, the data can be used for ranging and further on for positioning of mobile terminals. Simultaneously, this hardware-in-the-loop setup, can be used for channel measurements at 240 GHz under various environmental conditions.
- A Hybrid Network management controller. IHP will implement the complete Layer 2.5 as software solution (in Linux kernel- and user space). First version of Layer 2.5 will be used in the V1 demonstrator (Task 4.1). However, IHP will work further on Layer 2.5 software version to have the complete solution by the end of the project. To achieve high forwarding speeds, parallel data processing and some protocol-based solutions, such as frame aggregation have to be used. The achieving of a few Gbps data forwarding speed with this software version is expected and will be integrated in the V1 demonstrator. To support higher data rates, dozens of Gbps and more, the data plane must be realized in hardware, or using dedicated network processors. In this project IHP will examine the data plane implemented on FPGA platform. However, the FPGA implementation of data plane will include only basic functionality needed to examine and evaluate frame processing using hardware. Nevertheless, this FPGA-based implementation will not be part of the integrated demonstrator (V2, with ultra-high data forwarding) due to additional requirement on resources, high extra costs, and manpower.

3.2 Management structure, milestones and procedures WORTECS will use a light and flexible project management structure which will guarantee the objectives are met, but allow experts to generate creative solutions to extremely challenging problems. WORTECs partners are experienced in such projects and consider this to be the optimal approach. Orange, as the project coordinator, has appointed a project leader, with previous experience in the lead of European projects. The project leader will be responsible of both administrative/financial/legal/contractual issues and more technical areas (the project has a reasonable size so it is not required to split the Project/Technical Management tasks).
The project is split in 5 work packages, the work package leaders being a mix between industrial partners (networks operator, SMEs) and research partners (academics, research centres). This will, stimulate technological transfer between research and industry. Work package leaders also support the project coordinator in the day-to-day management of WORTECS.
In order to ensure the technical relevance of the proposed solutions and the end-to-end coherence through the different work packages, three technical leaders have been nominated in relationship with the three main topics addressed by WORTECS (i.e. radio solution-ORA, optical solution-UOXF and radio/optical management-IHP). The overall project structure is shown in Figure 3.3. More detail on implementation is given in the following sections.
Figure 3.3. Wortecs management structure.
3.2.1 Management structure The management organisation comprises the two main following parts: General Assembly (GA) – consisting of one representative from each partner of WORTECS consortium. Project Management Team (PMT) – consisting of the project coordinator, work package leaders and the technical leaders.
WORTECS 53
3.2.1.1 General Assembly (GA) The General Assembly (GA), chaired by the project leader, is the highest body of the consortium that takes the final decisions. One representative per partner is chosen to constitute the GA (total of 7 members). The General Assembly considers aspects including consortium agreement, allocation of budget and responsibilities to partners, modifications of the project’s contract if needed (e.g. new partner in the consortium, modification of parts of the work initially planned…), resolution of conflicts when not solved at lower levels of the organizational structure. The General Assembly meets at least once a year (meetings can be co-located in time and location with WORTECS plenary meetings) but can take decisions between meetings if required. Terms of reference of the GA (including voting rules) will be set out in the consortium agreement.
3.2.1.2 Project Management Team The Project Management Team (PMT) consists of: - the project leader, who chairs the PMT (1 – WP1) - the work package leaders (4 – WP2 to WP5) - the technical leaders (3).
The PMT leads day to day running of the project, based on the directions agreed within the GA. PMT will ensure: - the technical and scientific relevance of the work achieved by WORTECS consortium, - the initially agreed time plan is met, - the initially agreed budget is met. PMT is the entity that will: - formally approve the content of the deliverables, - formally approve the dissemination actions .
The first PMT meeting will be held at the project kick-off meeting; the following technical meetings will also be co-located with plenary meetings in order to minimise travel costs. Regular audio conferences will be planned in-between the physical meetings in order to ensure the projects evolves in the right direction with the right timing. In each PMT meetings WP leaders will share the status of their WP’s activities and progress.
Focus on key roles - Project leader The WORTECS project will be coordinated by Orange, which has nominated M. Olivier BOUCHET as the project leader. The Coordinator is the interface between the European Commission and the members of WORTECS consortium: he will inform EC about the project outcomes and share with the GA EC directives as well. He will coordinate the activities of all partners, and will ensure that the overall scope, objectives and direction of the project are in line with the initial project plan. The project leader also controls that each partner respect their own initial commitments. As already mentioned, the project coordinator, represented by the project leader, chairs both GA and PMT (and so is responsible of their related scope of actions, quickly mentioned above).
- Work package leaders Each work package will be coordinated by a Work Package Leader (WPL). WPLs are responsible of the everyday progress of their related WP (planning and organization of the work, organization of dedicated calls on a regular basis, ensure availability and completion of deliverables
WORTECS 54 to be produced by their due date, ensure global objectives of the WP are reached, report to project leader, interact with technical leaders…). The consortium has already allocated WP responsibilities to specific organizations (as can be seen in Work Package descriptions). The initially nominated WP leaders are: WP1: M. Olivier Bouchet (Orange) WP2: M. Christian Gallard (Orange) WP3: M. Michel Corriou (B-Com) WP4: M. Jorge Garcia (Oledcomm) WP5: Professor Dominic O’Brien (University of Oxford)
- Technical leaders The Technical Leaders of the project are: M. Guillaume Vercasson (BCM) on radio. Professor Dominic O’Brien (University of Oxford) on optical wireless communications. M. Marcin Brzozowski (IHP) for hybrid networks expertise. Technical Leaders are responsible of the scientific relevance of the solutions proposed and studied within the project, and ensure and end-to-end coherence of the technological choices from uses cases and requirements definition to implementation work. They have a role across work packages but work together with work package leaders, and can be seen as the WORTECS technical references or advisers.
3.2.2 Milestones The following milestones are imposed as control points for the overall progress of the project.
Table 3.2a: List of milestones Milestone Milestone name Related Due date Means of number work (in month) verification package(s) M2.1 WORTECS Use cases and WP2 M3 D2.2 delivered requirements agreed M3.1 WP3 radio and wireless optical WP3 M15 D3.2 delivered communication systems specifications for virtual reality WP4 implementation M3.2 Terabit system specifications WP3 M24 D3.3 delivered (PHY, MAC, Hybrid Network) for WP4 implementation M4.1 VR PoC WP4 M23 D4.1, D4.2 and D4.3 delivered M4.2 Terabit system PoC WP4 M37 D4.5 and D4.6 delivered
3.2.3 Procedures to ensure project execution and quality of work Decision-making and conflict resolution mechanisms The overall philosophy that should be applied is that decisions must be taken on the lowest possible level (e.g. inside the concerned work package), on a consensus basis; decision, between e.g. competing solutions, must be justified by clear technical elements (e.g. performance WORTECS 55 comparisons with similar simulation assumptions, complexity figures, required amount of human resources to be involved). When an agreement cannot be achieved, the WP leader reports to project coordinator, and a decision is taken within PMT based on a proposal to solve the issue brought by the project coordinator; if no consensus can be found, the decision is taken at GA level (with a vote if required). The final process for decision-making will be described within the consortium agreement. Such a philosophy and such a process will also be followed in order to resolve potential conflicts between partners.
Internal project communication and information flow Work progress within the work packages (including reports and meeting minutes, dissemination actions, patent applications…) will be reported by WPLs to the PMT, and then from the PMT to the GA, where all partners are represented. The feedback to these reports and every kind of decisions or recommendations will be shared with all the partners by PMT as well. GA is the room where all the partners are represented and then is the perfect place for general discussions. Exchange of information between partners will be supported by tools such as project mailing lists, workspace in order to share documents, and audio-and-video conferencing facilities (with which applications can be shared or documents displayed by and to all the participants).
Progress monitoring, reporting and deliverables The documentation of the project will consist mainly of: - Internal project reports and Deliverables, provided to European Commission according to the agreed time plan; - Partner reports, WP reports, management reports every 4 months basis o Management reports will be delivered to European Commission and will give an overview of the project outcomes in terms of achievements, project status, human and financial resources consumed in the past period. The deliverables of WORTECS project will be made available in the project workspace. There will be made available to PMT 30 days before the official submission to the Project Officer for review, in order to raise any issues or concerns.
Management of risks The following table summarizes the risks identified, before the project starts, by WORTECS partners and gives some solutions that could be applied in order to mitigate them.

A partner withdraws from the All WPs Risk: Low. Other partners in the Consortium. Consortium (with similar level of expertise) committed to partially cover the missing contribution. In case of insufficient expertise of the other partners, a new partner will be invited to join in. Underestimation of the effort All WPs Risk: Low. The consortium has needed to study and to develop analysed the required effort carefully. necessary tools and technology. The activities versus effort required will be monitored closely during the project’s lifetime, and in case of problems the work focus will be re- aligned and resources will be relocated accordingly. Change/delay in standards or WP3,WP4 Risk: Medium. The project plans, regulatory timelines. specifically WP4, will very closely track and reviews standards and regulatory timelines, e.g., IEEE 802.15.7, IEEE 802.11, EN 60825, 5GPP releases. If there are changes that may affect planned input to standards, the dissemination will be adjusted accordingly and work plan may be re- adjusted to support the updated plan. Radio/Optic interfaces design or WP3 Risk: Medium. WP3 will propose new module design not delivered by WP interface and transceiver architecture 3 or delivered too close to the end designs. The schedule will be looking of the project to achieved PoC or carefully to give time for WP4 partner perform system level evaluations to achieve the PoC. In case of late with it. delivery, it should be possible to use a sub-module from prior projects (e.g., OMEGA, ACEMIND, mmMagic, UP- VLC). Radio/Optic component, sub- WP4 Risk: High. WORTECS will specify module or key technologies are not demonstrators independent of each available at the expected time other to avoid any domino effect. An alternative key technology solution with less features will be used to finalize the PoC. Not able to reach the Tbps in a WP4 Risk: Medium. WORTECS partners room have demonstrated significant data rates (100s of Gbps) before the project start, showing the strong foundation of the
WORTECS 57
work. Project focuses on scalability, so project will define clear route to achieving 1Tbps and solutions to the resulting challenges, even if 1Tbps is not reached within timescale of WORTECs.
Consortium agreement Once WORTECS is selected by the European Commission, the Project Coordinator, together with all partners, will draft a Consortium Agreement (CA). This will be reviewed and signed by all the partners before the signing of the Grant Agreement with the European Commission. The Consortium Agreement will include details on governance and management, financial provisions, project results (ownership, dissemination…), access rights, confidentiality and liability. The WORTECS Consortium Agreement will be based on the MCARD-2020 model as for Horizon 2020.
3.3 Consortium as a whole WORTECS gathers together innovative, world leading LiFi SMEs Oledcomm (France) and PureLiFi (UK), Global telecommunications operator Orange (France) and research institutes namely BCOM (France) and IHP (Germany). These are joined by academic partners, leaders in optical wireless communications from the University of Oxford (UK) and the University of Las Palmas (Spain). All the partners have already participated to European projects (OMEGA, METIS, MiWEBA, mmMAGIC, ACEMIND). The Table 3.3a indicate the competence/skill for each partner. Orange is one of the world’s leading telecommunication operators, and one of the main European operators for mobile, wireless and broadband internet services. Orange will also play a key role in disseminating and promoting the outcome of the project to relevant fora and standard bodies such as IEEE or 3GPP. Oledcomm and PureLiFi are world leading SMEs in the area of Optical Wireless Communications and Light Fidelity (LiFi) products and research. These companies are very successful university spin-offs from Versailles and Edinburgh respectively, with a strong research-base. This is particularly relevant to WORTECS, as they bring to the consortium the experience and know-how of taking results from research to product level. Both see clear opportunities in exploiting WORTECS results to expanding their products and commercial services. The University of Oxford and University of Las Palmas are world leading groups in the area of Optical Wireless Communications and Light Fidelity (LiFi). IHP and B-COM are leading research institutes in the area of physical and digital radio product and research. They bring very strong and highly relevant research competencies and expertise in wireless communication systems, and more specifically very deep knowledge of fundamental concepts, innovative methodologies and models, measurements, and simulation expertise in the field of mm-wave communications. B-COM is one of the leading research institutes in Virtual Reality research.
