The Federal Communications Commission (FCC) in the USA adopted a Report and Sixth Report and Order on April 29, 2025, establishing a framework for sharing the Lower 37 GHz frequency band (37–37.6 GHz) between federal and non-federal users. The FCC also issued a Further Notice of Proposed Rulemaking (FNPRM) to revise emissions limits for Upper Microwave Flexible Use Service (UMFUS) operations above 37 GHz.
