Progress in Opening Access to Spectrum above 100 GHz

While the International Telecommunication Union (ITU) Table of International Allocations and most national allocations tables have listed spectrum allocations up to 275 GHz, in reality specific policies for technologies above 100 GHz have been very rare until recently. Both Conference of European Postal & Telecommunications (CEPT)/ERC, the group of European spectrum regulators, and the Japanese regulator MIC have had some specific provisions for this spectrum region. On March 15, 2019 the U.S. spectrum regulator FCC made a decision for this spectrum that opens a variety of new opportunities for use of this spectrum.
