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)”. Potential applications of interest include wireless data centers, wireless intra-device communication and wireless backhauling. Although, the focus of the IG THz has been the frequency range beyond 275 GHz, in the SG 100 G the frequency range will be kept open to other bands such as the consideration of 60 GHz and FSO. The wave length of interest for the PHY will be millimeter-wave or shorter.
In March 2014 the Task group 3d has been established, which will work on an amendment of 802.15.3 targeting 100 Gbit/s for switched point-to-point links. Applications of interest will be wireless data centers, wireless backhauling/fronthauling, kiosk downloading and intra-device communication.
