Space Bureau Extends Comment and Reply Comment Deadlines for Notice of Proposed Rulemaking Regarding Facilitating More Intensive Use of Upper Microwave Spectrum
In the document, the Space Bureau extends the comment and reply comment deadlines for the Facilitating More Intensive Use of Upper Microwave Spectrum Notice of Proposed Rulemaking in SB Docket No. 25-305, FCC 25-70, that was released on 29 October 2025 and published in the Federal Register on 3 December 2025. 90 Federal Register (FR) 59784, 22 December 2025; Title 47 Code of Federal Regulations (CFR) Part 10: This extension of the comment period to the proposed rule is identified by SB Docket No. 25-305, FCC 25-70. The full text of the proposed rule is available from the Commission's website at Documents are also accessible from the FCC's Electronic Document Management System (EDOCS) by searching the Docket Number. Comments are due on or before 20 January 2026; reply comments are due on or before 4pm Eastern Time 18 February 2026. WTO Members and their stakeholders are asked to submit comments to the USA TBT Enquiry Point by or before 4pm Eastern Time on 18 February 2026.

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 of the UMFUS bands and improve licensing efficiency.
