Terahertz Propagation Characteristics for 6G Mobile Communication Systems

摘要

The 6th generation (6G) mobile communication system is being actively pursued worldwide. To satisfy extreme-high-speed-communication, one solution is to utilize terahertz bands above 100 GHz because a remarkably wider frequency bandwidth can be utilized than in 5G. To determine the service frequency bands on the basis of system performance for 6G, frequency dependency of path loss and channel properties needs to be understood. In this paper, we introduce our concept of a new network topology for 6G and then show the frequency dependency of human blockage, building shadowing, and scattering effects from a rough building surface up to 150 GHz.
