High data throughput wireless communication systems are central to our lives, livelihoods, and national security, with recent increases in remote working particularly emphasising the importance of high performance and resilient data communication systems. Data traffic is increasing exponentially, with the fastest-growing part of this increase being on wireless channels, as mobile users increasingly make use of online services. This is unsustainable using state-of-the-art radio frequency and microwave systems, and further compounded by the shortage of allocable electromagnetic spectrum into which current radio frequency and microwave wireless communications can grow. Although recent development of commercial products at millimetre wave frequencies (60-95 GHz) offer a potential solution, they still remain limited by an available bandwidth of <7 GHz per band, and are not viable to meet the increasing demand. In this programme, we will develop the first integrated high throughput wireless communication systems operating at terahertz carrier frequencies, between 2-5 THz. The advantage of using a terahertz carrier relative to microwave frequency carriers is the much greater available bandwidth, and hence higher data rate, that can be supported. We will demonstrate a two orders-of-magnitude increase in data rates over state-of-the-art radio frequency and microwave systems, beyond 100 Gbit/s and towards 1 Tbit/s.We will achieve these ambitious goals through the concurrent development of new and specialized terahertz frequency sources, detectors, modulators, and signal control techniques, with specifications not only defined and evaluated in the context of the overall system requirements, but also individually refined throughout the programme in response to the performance and technical specification obtained for each component. This programme is timely and important, and will position the UK at the international forefront of new, secure and reliable wireless communications infrastructures and networks. Our programme will support the UK requirement for national capability in advanced communication systems, and safeguard the UK against vulnerability to overseas technology and export controls in a changing international landscape. It will support the UK's major space communications industry, and the creation of a resilient global internet, with satellite-to-satellite interconnectivity, and contribute to the UK's 2050 net-zero targets by facilitating immersive virtual working. Finally, we will attract, train and inspire a diverse cohort of future UK academic and industrial leaders and innovators in a holistic, collaborative, and vibrant cross-disciplinary environment, promoting outreach and advocacy, and build capability in an area of national shortage.

高数据吞吐量无线通信系统对我们的生活，生计和国家安全是核心，最近的远程工作增加特别强调了高性能和弹性数据通信系统的重要性。数据流量呈指数增长，随着移动用户越来越多地利用在线服务，这一增加的增长最快的部分是无线渠道。这是使用最先进的射频和微波系统的不可持续的，并且由于可分配的电磁频谱的短缺而进一步加剧了当前射频和微波无线通信的不足。尽管最近在毫米波频率（60-95 GHz）的商业产品开发提供了潜在的解决方案，但它们仍然受到每个频段<7 GHz的可用带宽的限制，并且不可行，无法满足增长的需求。在此程序中，我们将开发在2-5 THz之间在Terahertz Carrier频率下运行的第一个集成的高吞吐量无线通信系统。使用Terahertz载体相对于微波频率载体的优点是可以支持的更大的带宽，因此可以支持更高的数据速率。我们将证明，与最先进的射频和微波系统相比，数据速率增加了两个级别的命令，超过100 Gbit/s，朝1 tbit/S.我们将通过并发开发实现这些雄心勃勃的目标新的和专业的Terahertz频率来源，探测器，调节器和信号控制技术，规格不仅在整体系统要求的背景下定义和评估，而且在整个程序中都可以单独完善整个程序，以响应于获得的性能和技术规范。每个组件。该计划是及时且重要的，它将将英国定位在新的，安全和可靠的无线通信基础架构和网络的国际前沿。我们的计划将支持英国对高级通信系统中国家能力的要求，并保护英国不受海外技术的脆弱性和在不断变化的国际景观中出口控制的脆弱性。它将支持英国的主要太空通信行业，并通过卫星到卫星的互连性创建具有弹性的全球互联网，并通过促进沉浸式虚拟工作来为英国的2050年净零目标做出贡献。最后，我们将在整体，合作和充满活力的跨学科环境中吸引，培训和激发多种未来的英国学术和工业领导者和创新者，促进外展和倡导，并在国家短缺地区建立能力。
