AGENCY:

Federal Communications Commission.

ACTION:

Proposed rule.

SUMMARY:

In this document, the Federal Communications Commission (Commission) seeks comment to refresh the record in the rulemaking on Modernizing and Expanding Access to the 70/80/90 GHz Bands (85 FR 40168, July 6, 2020; 86 FR 60436, Nov. 2, 2021) to address the potential for use of the 71-76 GHz, 81-86 GHz, 92-94 GHz, and the 94.1-95 GHz (70/80/90 GHz) bands to provide broadband internet access to consumers and communities that may otherwise lack robust, consistent connectivity. Specifically, the Commission previously proposed new and updated rules to further enable non-Federal uses of the 70/80/90 GHz bands, which are currently allocated on a co-primary basis for Federal and non-Federal use. This document seeks to refresh the overall record in the docket and seeks comment, in particular, on the proposals made in a filing by the National Telecommunications and Information Administration (NTIA) on October 17, 2023 (NTIA October 17 Filing). In that filing, NTIA proposed technical rules and interference mitigation measures, including operating parameters for links to endpoints in motion in 71-76 GHz and 81-86 GHz, to protect current or ( printed page 74098) planned Federal operations in these frequencies and in adjacent bands.

DATES:

Comments are due on or before November 8, 2023.

Synopsis. With this document, the Wireless Telecommunications Bureau (Bureau) seeks to refresh the overall record in WT Docket No. 20-133 and seeks comment, in particular, on the proposals in the NTIA October 17 Filing. In its 70/80/90 GHz NPRM, the Commission proposed new and updated rules to further enable non-Federal uses of the 71-76 GHz, 81-86 GHz, 92-94 GHz, and 94.1-95 GHz bands (collectively, the 70/80/90 GHz bands), which are currently allocated on a co-primary basis for Federal and non-Federal use.[1] The Commission specifically committed to “coordinate any proposed rule changes with the affected agencies and the National Telecommunications and Information Administration,” noting the need to “work with NTIA to evaluate potential impacts associated with any new or expanded non-Federal use of shared allocations.” [2]

The 70/80/90 GHz NPRM sought comment on a range of issues, including proposals by Aeronet Global Communications, Inc. (Aeronet) to use the bands to provide broadband service to aircraft and ships in motion.[3] The Commission also made proposals and solicited comment in part relating to applicable antenna standards, the extant link registration process, and possible band channelization.[4] Among other developments in this proceeding, on October 17, 2023, NTIA submitted a filing to supplement the record—comprised of a cover letter and three attachments—proposing technical rules and interference mitigation measures, including operating parameters for links to endpoints in motion in 71-76 GHz and 81-86 GHz, to protect current or planned Federal operations in these frequencies and in adjacent bands.[5] The NTIA October 17 Filing is based on the work of a technical interchange group (TIG) comprised of representatives from affected Federal agencies.[6]
