Reconfigurable Intelligent Surfaces (RIS) are rapidly emerging as one of the most transformative technologies within the future smart mobility ecosystem, offering a paradigm shift in how wireless communication environments are designed, optimised, and experienced. Unlike the traditional model in which mobile networks must adapt to a fixed physical environment filled with signal reflections, blockages, and unpredictable interference, RIS enables the environment itself to become programmable, intelligent, and dynamically responsive. Through the deployment of ultra-thin, low-power, metasurface panels composed of a dense array of passive or semi-passive elements, RIS can control electromagnetic wave propagation in real time, shaping signals to enhance coverage, boost data rates, reduce latency, and improve the overall reliability of wireless connectivity. This innovation is particularly significant for next-generation mobility applications—autonomous vehicles, connected public transport.
