Wi-Fi technologies are integral to our internet-connected lives. Most of the world’s wireless data passes over one of the global Wi-Fi standards. For more than 20 years the Communication Systems & Networks (CSN) Group has contributed towards the development of these technologies, and to products that conform to them. In partnership with Cartesian, CSN has developed a de-facto Wi-Fi test standard that addresses the core market need to verify and validate the Wi-Fi performance of new products. The approach combines the Group’s work in 1) Wi-Fi antenna design, integration and verification, 2) in-home propagation modelling (ray tracing) and 3) real-world multi-antenna WLAN throughput evaluation. Using this new process, the Group has been working with several of the UK’s, Europe’s and the world’s biggest broadband internet and TV providers to optimise their Wi-Fi product designs. As an example, the Group worked closely with Virgin Media to ensure that their latest Super Hub became “the best-in-class Wi-Fi router for cost/performance and quality of service”.
