Resonant Beam Communications
The vision and requirements of the sixth generation (6G) mobile communication systems are expected to adopt free-space optical communication (FSO) and wireless power transfer (WPT). The laser-based WPT or wireless information transfer (WIT) usually faces the challenges of mobility and safety. We present here a mobile and safe resonant beam communication (RBCom) system, which can realize high-rate simultaneous wireless information and power transfer (SWIPT). We propose the analytical model to depict its SWIPT procedure. The numerical results show that RBCom can achieve 7.5 Gbit/s with 200 mW received optical power, which seems to connect the transmitter and the receiver with a mobile "wireless optical fiber".
