The main theme of FIWIN5G is the expansion, in terms of both carrier frequency and bandwidth, of optically supported wireless links. As detailed below, such systems have very recently surpassed 100Gbit/s for the first time. This opens up new opportunities for short-haul wireless links to compete with core optical fibre speeds. As the core moves towards 400Gbit/s, we proposed to develop the next generation of systems and components that will support such data-rates wirelessly by using integrated photonic technologies.
