The FCC has recognized that the rapid growth of the commercial space economy has led to a demand for spectrum that exceeds previous expectations under the Upper Microwave Flexible Use Spectrum (UMFUS) framework. The lack of millimeter wave band adoption by terrestrial services has rendered UMFUS a barrier to efficient spectrum use and next-gen satellite deployment.

In response, the FCC adopted a Notice of Proposed Rulemaking (NPRM) to review sharing rules for the 24 GHz, 28 GHz, upper 37 GHz, 39 GHz, 47 GHz, and 50 GHz bands. The NPRM seeks comments on proposals to enhance spectrum use and manage increasing license demand, including streamlining application processes. Proposed changes aim to reduce delays associated with the current requirements, potentially implementing certifications, limiting technical showings, and adopting de minimis exceptions.
