PATH LOSS MODEL IN INTELLIGENT RADIO ENVIRONMENT
Keywords:Reconfigurable intelligent surface, Intelligent reflecting surfaces, Beyond 5G, Pathloss model, Smart radio environment.
Smart reflective surface is a new technology that is being researched and deployed to develop wireless communication systems, as well as 5G, post-5G (B5G) and future 6G mobile networks. The surface contains reconfigurable electromagnetic metamaterial to direct the beam from the source to the desired receivers with maximum signal strength. The paper provides a pathloss and channel model in a smart surface-assisted communication system built based on physical-optical techniques and Snell's light reflection theorem. With mathematical expressions, it will provide researchers with a way to calculate, simulate, analyze, evaluate and calibrate communication channels to achieve optimal efficiency before deploying experimental fabrication. or for comparison with other information transfer enhancement technologies such as AF relay and amplifier, MIMO beamforming, and BackCom backscatter communication.
