The FCC's NPRM, proposes a broad review of the rules governing the coexistence of Fixed-Satellite Service (FSS) and Upper Microwave Flexible Use Service (UMFUS) in high millimeter wave bands such as 24, 28, upper 37, 39, 47, and 50 GHz.

The FCC begins with an assessment that the framework adopted in 2016 in "Spectrum Frontiers" was designed with the expectation of a very intensive and widespread terrestrial 5G deployment and a relatively low demand for satellite ground stations.

The NPRM seeks a more scalable, automated regime that adapts to market evolution, enabling substantial growth in satellite ground stations without jeopardizing terrestrial investments, and requests detailed comments on technical impacts, cost-benefits, and implications for small entities.

WHOM DOES IT IMPACT?

The direct impact is felt by FSS satellite operators and licensees, UMFUS terrestrial licensees, infrastructure manufacturers and integrators, operators, backhaul providers, and supply chain ecosystems.

CONCLUSION:

The FCC is acknowledging that the actual market for millimeter wave spectrum has become more satellite-oriented than anticipated and is proposing to modernize the scheme to enable that growth without negating terrestrial potential. If adopted, the reform will likely substantially accelerate FSS deployments and redefine regulatory coexistence in the UMFUS bands.
