Overview

In 2008 IEEE 802.15 created the THz Interest Group (IG THz). The focus was primarily concerned with THz communications and related network applications operating in the THz frequency bands between 275 – 3000GHz. Such THz communications applications would include; component to component, board to board, machine to machine, human to machine and human to human, (indoor and outdoor) wireless communications. THz communication applications cover multiple categories with varying requirements. As envisioned, THz communications would overall employ wireless modulation methods of limited complexity, omni and/or directional antenna systems, and would typically offer very high data transfer rates in multiples of 10 Gbps, and up to possibly 1 Tbps, for parity with future fiber optic capacities. THz wireless systems could support transmission distances ranging from the very short (few centimeters or less) to relatively long distances of several kilometers.

In July 2013 the IG THz has been upgraded to a study group with the scope of determining the validity of a standard on 100G (100 Gbit/s over Beam switchable wireless point-to-point 40/100 Gbps links).

In March 2014 the task group 3d (TG3d) has been established, which works on an amendment of 802.15.3 targeting 100 Gbit/s for switched point-to-point links. Applications of interest is wireless data centers, wireless backhauling/fronthauling, point-to-point close-proximity communication including kiosk downloading and intra-device communication. Potential applications of interest include wireless data centers, wireless intra-device communication and wireless backhauling.  Operation is considered in bands from 252 GHz to 325 GHz at ranges as short as a few centimeters and up to several 100m.
