项目摘要

The continued exponential growth in mobile traffic created a need for new technologies that are able to provide communication efficiently at parts of the spectrum other than the RF spectrum currently in use. A potential disruptive solution is optical wireless (OW) communication. OW offers over three orders of magnitude more bandwidth than RF, with about 540 THz of spectrum. It is the best choice of spectrum beyond millimeter waves, where unlike the THz spectrum (the other possible choice), OW avoids complex sources and detectors and has good indoor channel conditions.A Terabit Bidirectional Multi-user Optical Wireless System (TOWS) uses new concepts in cellular optical communications to develop offer capacities at least two orders of magnitude higher than the current planned 5G optical and radio wireless systems, with a roadmap to wireless systems that can offer up to four orders of magnitude higher capacity. The high aggregate capacities to be provided by TOWS requires a comprehensive networking infrastructure to support the management and sharing of these capacities to meet future wireless applications.This project will focus on optimizing the networking infrastructure recognising the importance of a number of key optimisation metrics , including capacity, delay sensitivity, resilience, fairness, cost effectiveness and energy consumption, and key constraints such as eye safety, heat dissipation in devices and ease of installation and use.

移动通信量的持续指数增长产生了对新技术的需求，这些新技术能够在目前使用的射频频谱以外的频谱部分有效地提供通信。一个潜在的颠覆性解决方案是光无线通信（OW）。OW提供的带宽比RF多三个数量级，大约有540太赫兹的频谱。它是毫米波以外频谱的最佳选择，与太赫兹频谱（另一种可能的选择）不同，OW避免了复杂的源和探测器，并且具有良好的室内信道条件。太比特双向多用户无线光通信系统（TOWS）使用蜂窝光通信中的新概念，开发比当前规划的5G光学和无线电无线系统至少高出两个数量级的容量，并且无线系统的路线图可以提供高达四个数量级的容量。TOWS提供的高聚合容量需要一个全面的网络基础设施来支持这些容量的管理和共享，以满足未来的无线应用。该项目将重点优化网络基础设施，认识到一些关键优化指标的重要性，包括容量、延迟灵敏度、弹性、公平性、成本效益和能耗，以及眼睛安全、设备散热和安装和使用便利性等关键限制。
