Terahertz communications are envisioned as a key technology for 6G, which
requires 100+ Gbps data rates, 1-millisecond latency, among other performance
metrics. As a fundamental wireless infrastructure, the THz communication can
boost abundant promising applications, including next-generation WLAN systems
like Tera-WiFi, THz wireless backhaul, as well as other long-awaited novel
communication paradigms. Serving as a basis of efficient wireless communication
and networking design, this paper highlights the key THz channel features and
recent advancements in device technologies. In light of these, impact and
guidelines on 6G wireless communication and networking are elaborated. We
believe the progress of THz technologies is helping finally close the so called
THz Gap, and will realize THz communications as a pillar of 6G wireless
systems.
