Directional Terahertz Communication Systems for 6G: Fact Check

Abstract

Sustaining a flexible and ubiquitously available high-data-rate (high-DR) network that is capable of supporting a massive number of end users demands the exploitation of higher-frequency bands, such as the terahertz band (0.1–10 THz). However, the utilization of terahertz wireless systems comes with a number of challenges, many of them associated with the very high propagation losses of terahertz signals, which require the utilization of high-gain directional antennas with strict beam alignment requirements as well as the low signal penetration of (sub)millimeter waves, which leads to intermittent blockage and shadow areas.
