  • TV White Space for Internet Access in the Developing World Tawachi Nyasulu1, Dani Anderson1, David H
    TV White Space for Internet Access in the Developing World Tawachi Nyasulu1, Dani Anderson1, David H. Crawford1, Robert W. Stewart1, Malcolm Brew2 1 Centre for White Space Communications, Department of Electronic and Electrical Engineering, University of Strathclyde, Glasgow. 2 Mawingu Networks, Kenya. [email protected] Abstract In 2013, the University of Strathclyde began working with Microsoft’s 4Afrika programme to create a data communications network in Kenya, providing connectivity and Internet access to a number of rural locations, including schools and health clinics in remote villages. This project has led to the development of Mawingu Networks, a fully licensed internet service provider using “White Space” radio frequencies to enable low cost internet access via renewable powered base stations. Since going live in 2016, the network now has more than 27,000 unique users across a wide geographical area. Despite the fact that universal Internet access is part of the UN’s sustainable development goals, and has been shown to spur social and economic development, a large percentage of people in developing countries do not yet have access. This is often due to a lack of infrastructure, large distances and dispersed populations. This poster presents an overview of TV White Space technologies, with emphasis on our 4Afrika collaboration with Microsoft and Mawingu Networks. In addition, an insight into some recent developments in other African countries (Malawi, Zambia, and Ghana) is presented. What is TV White Space? TVWS Network Architecture Evolution Wireless communication is transmitted using radio spectrum. ‘White Spaces’ are TVWS standards and regulations have transformed the TVWS network architecture.

  • Optimizing City-Wide White-Fi Networks in TV White Spaces
    1 Optimizing City-Wide White-Fi Networks in TV White Spaces Sneihil Gopal∗, Sanjit K. Kaul∗ and Sumit Royy ∗Wireless Systems Lab, IIIT-Delhi, India,yUniversity of Washington, Seattle, WA fsneihilg, [email protected], [email protected] F Abstract—White-Fi refers to WiFi deployed in the TV white spaces. Unlike its ISM band counterparts, White-Fi must obey requirements (28) (27) TVTX1 that protect TV reception. As a result, optimization of citywide White- TVRX2 Fi networks faces the challenges of heterogeneous channel availability (28) TVRX1 and link quality, over location. The former is because, at any location, (27) White-Fi Network TV channels in use by TV networks are not available for use by White-Fi. TX2 The latter is because the link quality achievable at a White-Fi receiver is determined by not only its link gain to its transmitter but also by its link gains to TV transmitters and its transmitter’s link gains to TV receivers. In this work, we model the medium access control (MAC) throughput of a White-Fi network. We propose heuristic algorithms to optimize the throughput, given the described heterogeneity. The algorithms assign (27) TVRX power, access probability, and channels to nodes in the network, under 1 the constraint that reception at TV receivers is not compromised. We (27) TVTX evaluate the efficacy of our approach over example city-wide White-Fi 1 networks deployed over Denver and Columbus (respectively, low and high channel availability) in the USA, and compare with assignments cognizant of heterogeneity to a lesser degree, for example, akin to FCC Fig.

    Cambridge White Spaces Consortium Recommendations for Implementing the Use of White Spaces: Conclusions from the Cambridge TV White Spaces Trial Contents Executive Summary: Key Findings and Recommendations 2 What are TV White Spaces? 6 Geolocation Databases: the Key to Securing Flexible, 8 Dynamic and Cost-effective Spectrum Access Economic and Policy Benefits from Use of White Spaces 9 The EU Digital Agenda 10 About the Cambridge Trial 11 Trial Test and Measurement Programme 14 2 Executive Summary: Key Findings and Recommendations There is a growing view that the traditional method of allocating spectrum can create scarcity. Emerging techniques potentially allow a more flexible use of spectrum than the traditional approach where spectrum is allocated across a region for a particular use, but not necessarily used intensively throughout that region. Traditional spectrum allocations pre-date the recent growth in demand for wireless broadband connectivity and a more flexible approach could help address this demand. The fixed nature of radio spectrum as a physical asset, coupled with the increasing demand for it, suggests that it is now appropriate to consider smart technology to facilitate sharing of the radio spectrum between different users and applications. A primary purpose of the Trial was to assist Ofcom, the UK regulator for media and telecommunications, in developing the In June 2011, 11 leading companies and regulatory framework which will facilitate Similar trials are also under way in Germany, organisations1 in the telecommunications, the use of TV white spaces and help to Finland, the USA and Singapore: thus, media and technology sectors worldwide achieve certain policy objectives, i.e., governments and regulatory authorities came together in a consortium to test improving spectrum efficiency and providing both internationally and throughout the the technical feasibility of using television universal broadband access.

At the same time, there is substantial innovation worldwide in applications, services and devices that use wireless data. As a result, demand for wireless data has grown rapidly, and continues to do so. 1.2 Wireless data communications require access to radio waves, known as spectrum. Spectrum is divided into different frequency bands and allocated for particular types of use. The majority of spectrum is allocated using licences, for instance licences to operate mobile phone services. Other spectrum use is made licence exempt, such as that for Wi-Fi. 1.3 However in some areas, allocated spectrum is not used in all locations and/or at all times. This is referred to as “white spaces” and it can be used by other devices and services. A new way to access spectrum, known as dynamic spectrum access, provides a means to use this spectrum.

  • Authorisation of the Use of TV White Spaces
    Authorisation of the Use of TV White Spaces as part of a Dynamic Spectrum Access Framework February 2020 Overview The Communications Authority of Kenya is the regulatory authority for the ICT sector in Kenya with responsibilities in telecommunications, e-commerce, broadcasting, postal/courier services and cybersecurity. The Authority is responsible for managing the numbering and frequency spectrum resources for the country as well as safeguarding consumers of ICT services. The Authority is committed to discharging its mandate to ensure that the ICT sector contributes to the socio-economic growth of Kenya, in line with its vision of a digitally transformed nation. The Authority is considering methods beyond the traditional model of dedicated spectrum licensing to individual operators in order to meet the rapidly increasing demand. In order to achieve this, one of the objectives of the Authority’s Strategic Plan (2018-2023) is to develop a framework for Dynamic Spectrum Access (DSA). Implementation of spectrum sharing is a key regulatory intervention that the Authority intends to adopt in order to accommodate varying levels of spectrum demand and over time, this approach may be a key strategy of spectrum management. Effective implementation of a spectrum sharing approach will enable efficient utilisation of the spectrum while protecting existing primary users from harmful interference. Spectrum sharing has the ability to increase capacity as it makes the fallow spectrum available without displacing incumbent users. The Authority envisions that this will be an important way to unlock maximum value from radiocommunication services and serve as a flexible way to reduce artificial spectrum scarcity. The Authority plans to authorise the commercial deployments for TV white spaces (TVWS), mainly for fixed broadband services, in the 470-694 MHz UHF Spectrum band, currently allocated to the broadcasting service on a primary basis as provided in the National Table of Frequency Allocations.

  • A Critique of Fcc's Tv White Space Regulations
    [STANDARDS] Ramachandran Ramjee Microsoft Research India Sumit Roy University of Washington USA Krishna Chintalapudi Microsoft Research USA Editor: Michelle Gong A CRITIQUE OF FCC’S TV WHITE SPACE REGULATIONS roadband access constitutes the “oxygen” for the Internet Era, to which end, the issue of spectrum management is foundational. In this position paper, we present an overview Bof FCC’s pioneering work framing TV white space rules that allows unlicensed access by secondary users while protecting licensed primary users. The core contribution of this paper is an in-depth analysis of FCC’s TV white space regulations (often treated as a global template). We argue that FCC’s current white space regulations does not achieve the desired balance between effectively promoting unlicensed secondary access and providing adequate protection of the primary. As more countries around the world look at framing white space regulations, we argue for incorporating a more flexible design that can catalyze a white space device ecosystem to flourish, similar to Wi-Fi.
