TOWS project is a multimillion 6G projected funded by the research council and the EPSRC in the United Kingdom. Our vision is to develop and experimentally demonstrate multiuser Terabit/s optical wireless systems that 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 targeted audience can span organisations in the academia and industrial sectors.
