Sub-terahertz propagation characteristics up to 150 GHz for 6G mobile communication systems

Abstract Extreme-high-speed communication exceeding 100 Gbps is one requirement for 6G. To satisfy extreme-high-speed-communication, solution to utilize terahertz bands above GHz. determine the new radio-interface technologies and service frequency 6G, propagation characteristics GHz need be understood. In this paper, we introduce our radio-network topology 6G then show dependency of key phenomena such as path loss in an urban environment, human blockage, scattering from a rough building surface up 150 Human blockage increases more diffused increases. path-loss characteristics, it was found that stronger than given by conventional model because effects surface.
