Iot Whitepaper
IoT Solution Whitepaper WHITEPAPER, MARCH 2019 THE GAME CHANGER FOR THE INTERNET OF THINGS 1 IoT Solution Whitepaper INTRODUCTION The Internet of Things (IoT) is rapidly creating new ecosystems, revealing new insights and efficiencies, and enabling a vast array of new services and business models. While headline- grabbing IoT applications such as augmented reality or self-driving cars capture the imagination, many IoT use cases do not need to rely on high-performance wireless modules and low-latency, high-bandwidth connectivity. For Low Power Wide Area (LPWA) applications—such as smart metering, tracking of assets, and monitoring equipment—the key requirement is the ability to periodically exchange small amounts of data easily, reliably, and cost-effectively. Unlike most other existing mobile communications technologies, Narrowband IoT (NB-IoT) is optimized for these types of applications—making NB-IoT an ideal network technology for a broad array of IoT solutions. Billions of devices Low data volume Low energy consumption Deep indoor penetration Up to 100x more devices per cell Bidirectional, infrequent transmission Up to 10 years of battery-powered +20 dB link budget (compared (compared to GSM) of low data volumes.

Reduced Complexity Detection of Narrowband Secondary Synchronization Signal for NB-Iot Communication Systems
S S symmetry Article Reduced Complexity Detection of Narrowband Secondary Synchronization Signal for NB-IoT Communication Systems Young-Hwan You Department of Computer Engineering, Sejong University, Gwangjin-gu, Gunja-dong 98, Seoul 05006, Korea; [email protected] Received: 1 July 2020; Accepted: 6 August 2020; Published: 11 August 2020 Abstract: Narrowband Internet of Things is one of the most promising technologies to support low cost, massive connection, deep coverage, and low power consumption. In this paper, a computationally efﬁcient narrowband secondary synchronization signal detection method is proposed in the narrowband Internet of Things system. By decoupling the detection of complementary sequence and Zadoff–Chu sequence that make up the synchronization signal sequence, the search space of narrowband secondary synchronization signal hypotheses is reduced. Such a design strategy along with the use of the symmetric property of synchronization signals allows reduced-complexity synchronization signal detection in the narrowband Internet of Things system. Both theoretical and simulation results are provided to verify the usefulness of the proposed detector. It is shown via simulation results that the complexity of the proposed detection method is signiﬁcantly reduced while producing some performance degradation, compared to the conventional detection method. Keywords: narrowband Internet of Things; narrowband secondary synchronization signal 1. Introduction With the rapid growth of the Internet of Things (IoT) industry, Low-Power Wide-Area (LPWA) technologies become more and more popular [1]. Recently, cellular LPWA solutions, such as enhanced Long Term Evolution for Machine-Type Communication (LTE-MTC), Extended Coverage-Global System for Mobile communications for the IoT (EC GSM-IoT), and Narrowband IoT (NB-IoT), have been envisaged as a promising technology for existing and future cellular networks [2–5].

It shall be noticed that this is actually a In this context, Internet of Things (IoT) services will be even new technology and, thus, not fully backward compatible with more impactful with respect to 5G systems. In order to cope with the huge amount of IoT devices, and the potentially large legacy 3GPP devices. Based on the lessons learnt from the capacity requirements for the most advanced of them (e.g., live initial 5G deployments and on the global societal and network camera feeds from first responders in emergency scenarios), trends, the translation from human-centric towards machine- non-terrestrial systems will be pivotal to assist and complement centric communications will be even more pronounced in the terrestrial networks. In this paper, we propose a multi- 6G. In fact, it is expected that the number of Machine-To- layer non-terrestrial architecture for NarrowBand-IoT (NB-IoT) services based on Geosynchronous Orbit (GSO) and Non GSO Machine (M2M) connections will increase from 8.9 billions (NGSO) nodes. To cope with both the number of devices and the in 2020 to 14.7 billions in 2023, representing one third of potentially large capacities, we propose to implement Minimum the global devices, [15].

Communications in the 6G Era
Communications in the 6G Era White paper The focus of wireless research is increasingly shifting toward 6G as 5G deployments get underway. At this juncture, it is essential to establish a vision of future communications to provide guidance for that research. In this paper, we attempt to paint a broad picture of communication needs and technologies in the timeframe of 6G. The future of connectivity is in the creation of digital twin worlds that are a true representation of the physical and biological worlds at every spatial and time instant, unifying our experience across these physical, biological and digital worlds. New themes are likely to emerge that will shape 6G system requirements and technologies, such as: (i) new man–machine interfaces created by a collection of multiple local devices acting in unison; (ii) ubiquitous universal computing distributed among multiple local devices and the cloud; (iii) multi-sensory data fusion to create multi-verse maps and new mixed-reality experiences; and (iv) precision sensing and actuation to control the physical world. With rapid advances in artificial intelligence, it has the potential to become the foundation for the 6G air interface and network, making data, compute and energy the new resources to be exploited for achieving superior performance. In addition, in this paper we discuss the other major technology transformations that are likely to define 6G: (i) cognitive spectrum sharing methods and new spectrum bands; (ii) the integration of localization and sensing capabilities into the system definition, (iii) the achievement of extreme performance requirements on latency and reliability; (iv) new network architecture paradigms involving sub-networks and RAN– Core convergence; and (v) new security and privacy schemes.

Prof. Sergey Andreev Examiners: Dr. Dmitri Moltchanov, Asst. Prof. Sergey Andreev Keywords: NB-IoT performance, LTE narrow band, cargo ships, smart transportation Narrow Band Internet of Things (NB-IoT) is the most advanced technology standard for short message services, such as sensor data, developed by 3GPP Release 13 and beyond. The NB- IoT is deployed over Long Term Evolution (LTE) Advanced Pro infrastructure and theoretically, it offers extended coverage up to 40 km from the base station. The objective of this thesis is to analyze the performance of NB-IoT technology in cargo shipment tracking using LTE cellular networks across the coastal line. Currently, about fifty thousand cargo ships use onboard Satellite communication system for all sorts of information exchange with the onshore data centers. The Satellite communication will continue to exist, even after deployment of NB-IoT. Apart from the machine critical data of the cargo ships, the non-emergency periodic short messages for polling meteorological and container metadata such as temperature, humidity, gaseous detection, etc. will be crucial for the quality of the shipment and the traceability.
