The spectrum sharing challenges for enabling large bandwidth mmWave/THz spectrum access above 100 GHz for 6G and other applications
Spectrum above 100 GHz is attractive for applications needing contiguous bandwidths greater than 20 GHz such as alternatives for optical fiber in situations where time urgency or difficult terrain make the low material cost fiber alternative infeasible. But unlike in the lower spectrum, above 100 GHz there is a high density of passive bands due to the presence of many molecular resonances of critical interest to climate scientists and radio astronomers. When the ITU created most of these bands in 2000, at the request of both US and European countries, it also agreed to their requested review of whether carefully controlled sharing of such passive bands was feasible. This webinar will review the technical challenges and potential benefits for sharing such bands subject to ITU quantitative protection goals that are in place. While such sharing is probably not feasible in lower bands, the key differences here are the small wavelengths and resulting small antenna sizes as well as the high atmospheric absorption above 100 GHz and the strong elevation angle dependence that makes terrestrial use with strong control of high elevation angle antenna sidelobes a promising path. The webinar will discuss this and other options as well as the ITU-R for a look at where these discussions are focused now and how one can participate in the deliberations.
