Terahertz networks could make wireless as fast as fibreoptic cables

Scientists from Hiroshima University and Panasonic have announced the development of a terahertz (THz) transmitter capable of transmitting digital data at a rate exceeding 100 gigabits (= 0.1 terabit) per second over a single channel using the 300-GHz band.

This technology allows achieving speeds 10 times or more faster than those offered by the fifth-generation mobile networks (5G), expected to appear around 2020.

The THz band is expected to be used for future ultrahigh-speed wireless communications. This range of frequencies are currently unallocated but fall within the frequency range from 275 GHz to 450 GHz, whose usage is to be discussed at the World Radiocommunication Conference (WRC) 2019 under the International Telecommunication Union Radiocommunication Section (ITU-R).

The technology will be presented at the International Solid-State Circuits Conference (ISSCC), to be held Feb. 5 — 9 in San Francisco.
