Currently, no spectrum is assigned to 6G. However, researchers and industry experts worldwide are convinced that additional frequency layers for the next generation of wireless communication will be essential. Sub-terahertz frequencies from 100 to 300 GHz are of interest to enhance performance as wider signal bandwidths beyond 10 GHz are available, enabling new applications such as short-range sensing of the environment. This video explains the background of candidate frequency bands in the D-Band (110 to 170 GHz) and G-Band (140 to 220 GHz).
