This is an extension of the Fellowship: 'Tackling the looming spectrum crisis in Wireless Communication'. Future economic success is inevitably tied to advancements in digital technologies. An essential component in the mix of digital technologies is digital communications, as also reflected in the EPSRC delivery plan under the heading of 'Connected Nation'. Wireless networking is fundamental to the achievement of 'connectivity'. According to a Cisco White Paper ("Cisco Visual Networking Index: Global Mobile Data Traffic Forecast Update, 2016-2021, White Paper", February 09, 2017), mobile data traffic has increased 18 times in the last 5 years alone. This corresponds to a compound annual growth rate (CAGR) of 78% with a further sevenfold increase expected between 2016 and 2021, reaching 49.0 exabytes per month by 2021. This growth is fueled by new wireless services on smartphones such as augmented and virtual reality and mobile TV. In addition, new networking paradigms such as the Internet of Things or more generally machine type communication will become increasingly important, especially to support operation of autonomous systems. This means that by assuming an average CAGR of 60% of global mobile data traffic, in 20 years from now a 500 MHz radio frequency (RF) channel allocated to a current RF system would need a bandwidth of 6 THz in 2037. The entire RF spectrum, which is currently used for wireless communications, only amounts to 0.3 THz. LiFi adds to the RF spectrum the nm-wave infrared and visible light spectrum with a combined bandwidth of 780 THz. This unregulated spectrum has the potential to make wireless communications future-proof. While the current Fellowship enabled ground-breaking research on achievable data rates using light emitting diodes (LEDs) - as the recently demonstrated 15 Gbps data rates from a single device - further substantial research efforts are required to unlock the full potential of the entire infrared and visible light spectrum, and to make LiFi an integral part of the fabric of wireless communications. Furthermore, research to date has primarily focused on advancing link level performance in static transmitter and receiver arrangements. In order to realise the vision of a world fully connected by light where car headlights, street lights, lights in offices, factories and homes including computer screens and indicator lights of home appliances, form the wireless networks of the future fundamental research is required to ensure that a terminal remains connected when it moves, and that interference generated when a large number of simultaneous transmissions are ongoing is mitigated effectively, or that random blockage does not cause link failure. Lastly, there are a number of challenges that come with the large increase in LiFi access points. Specifically, the many access points must be connected to the network backbone via suitable backhaul connections. LiFi systems that are composed of laser transmitters and solar cells as data receivers are envisaged to be a key for the backhaul challenge. It is these latter considerations which will also facilitate the eradication of the rural divide which currently prevents 60% of the world population from accessing digital communications.There are presently no viable solutions to these fundamental problems, and this is where this Fellowship extension comes in by taking the current internationally leading achievements to the next level. LiFi is now at the stage at which WiFi was 20 years ago, and the work undertaken in the next few years will be crucial in making this technology a success.

这是研究金的延伸：“解决无线通信中迫在眉睫的光谱危机”。未来的经济成功不可避免地与数字技术的进步有关。数字技术组合中的一个重要组成部分是数字通信，也反映在“连接国家”标题下的EPSRC交付计划中。无线网络是实现“连接”的基础。根据思科白皮书（“思科视觉网络指数：2016 - 2021年全球移动数据流量预测更新，白皮书”，2017年2月9日），仅在过去的5年中，移动数据流量就会增加18倍。这对应于78％的复合年增长率（CAGR），2016年至2021年之间的预计又增加了7倍，到2021年每月达到49.0个exabytes。这种增长源于增强和虚拟现实和虚拟现实和移动电视等智能手机上的新无线服务。此外，诸如物联网或更一般的机器类型通信等新的网络范式将变得越来越重要，尤其是为了支持自主系统的操作。这意味着，通过假设全球移动数据流量的平均CAGR的平均复合年增长率在20年内，分配给当前RF系统的500 MHz射频（RF）频道将需要2037年的带宽6 THZ。整个RF Spectrum，目前用于无线通信，仅用于无线通信，仅为0.3 thz。 LIFI增加了RF频谱，NM波红外和可见的光谱，结合带宽为780 THz。这种不受监管的频谱有可能使无线通信未来。尽管目前的研究金实现了对可实现的数据速率的开创性研究（LED） - 最近证明了来自单个设备的15 Gbps数据速率，但需要进一步的大量研究工作才能释放整个红外和可见光光谱的全部潜力，并使LIFI成为无线通信的整体组成部分。此外，迄今为止的研究主要集中在静态发射器和接收器安排中的链接水平性能。为了实现一个完全连接的世界的视野，在该光明中，汽车前灯，路灯，办公室和房屋的灯光在内，包括计算机屏幕和家用电器的指示灯，形成未来基础研究的无线网络，以确保终端在移动时保持连接，并在较大的互动范围内造成互联网的互动范围内，或者在互联网上进行了互动。最后，随着LIFI访问点的大幅度增加，面临许多挑战。具体而言，许多访问点必须通过合适的回程连接连接到网络主干。设想由激光发射器和太阳能电池组成的LIFI系统设想是回程挑战的关键。正是这些后一种考虑也将促进消除农村鸿沟，目前阻止了60％的世界人口访问数字通信。目前，对于这些基本问题，目前尚无可行的解决方案，这是该奖学金延伸的地方，通过将当前的国际领先成就带入下一个级别。 Lifi现在正处于WiFi 20年前的阶段，未来几年所做的工作对于使这项技术成功至关重要。
