Fettweis, 1St TERAFLAG Workshop Cassis 2018 6G research should look at the problem of transmitting up to 1 Tbps per user. This is possible through the efficient utilization of the spectrum in the THz regime. Extended spectrum towards THz will enable merging communications and new applications such as 3D imaging and sensing.
