Sub-THz frequencies

The frequency spectrum above 90 GHz offers opportunities for huge bandwidths, up to several tens of GHz, which is required to increase data rates and network capacities beyond 5G performance. The BRAVE partners are investigating frequencies in range from 90 to 200 GHz.

The radio spectrum above 90 GHz is today essentially known for being used by scientific services (e.g. astronomy observation, earth exploration and satellite services, meteorology,etc.)and has never been used effectively for radio wireless communications purposes. It should however be noted that the radio regulations already allocated several frequency bands above 90 GHz to the fixed and mobile services.

More specifically, within the range 90 – 200 GHz, the following frequency bands would provide opportunities to be considered for introducing terrestrial communication systems: 92 – 94 GHz, 94.1 – 100 GHz, 102 – 109.5 GHz, 111.8 – 114.25 GHz, 122.25 – 123 GHz, 130 – 134 GHz, 141 – 148.5 GHz, 151.5 – 164 GHz, 167 – 174.5 GHz, 174.5 – 174.8 GHz and 191.8 – 200 GHz. Up to 58.1 GHz bandwidth could be made available for new wireless communication services.

It can also be noted, that there is some ongoing work within CEPT (European Conference of Postal and Telecommunications Administrations) aiming to facilitate the deployment of fixed services links in the frequency ranges 92 – 115 GHz and 130 – 175 GHz.
