Facilitating More Intensive Use of Upper Microwave Spectrum; (12 page(s), in English)

Proposed rule - In this document, the Federal Communications Commission (''FCC'' or ''Commission'') seeks comment on a variety of measures aimed at facilitating more intensive use of spectrum in the 24 GHz, 28 GHz, upper 37 GHz, 39 GHz, 47 GHz, and 50 GHz bands (together, the UMFUS bands). These bands are shared between the terrestrial Upper Microwave Flexible Use Service (UMFUS) and the Fixed-Satellite Service (FSS) pursuant to the Commission's rules. When the Commission created this framework in 2016, it assumed that UMFUS bands would be used intensively as a part of terrestrial 5G networks, that earth station deployment in the bands would be relatively light, and that the technical rules adopted were necessary to protect terrestrial UMFUS operations but not too onerous to chill FSS earth station siting. Since that time, it has become more clear how the bands are being used for terrestrial service and how growth in the space economy has increased interest in using the UMFUS bands for FSS. Given these shifts, the requirements contained in the Commission's rules have proven to be an impediment to processing earth station applications in the bands. Accordingly, the NPRM would seek input on a variety of mechanisms that might facilitate more intensive use ofthe UMFUS bands and improve licensing efficiency.
