The Federal Communications Commission (the FCC or Commission) is correcting a final rule that appeared in the Federal Register on January 14, 2026. The document issued a final rule regarding "Implementation of the Final Acts of the World Radiocommunication Conference (Geneva, 2015) (WRC-15), Other Allocation Issues, and Related Rule Updates".
This document amends the Table of FM Allotments, of the Federal Communications Commission's (Commission) rules, by substituting Channel 277A for vacant Channel 221A at Hamilton, Alabama; Channel 261B1 for vacant Channel 261B at Coalinga, California; Channel 289A for vacant Channel 291A at Rocksprings, Texas; Channel 261A for vacant Channel 221A at Silverton, Texas; and Channel 281C2 for vacant Channel 260C2 at Spur, Texas. The existing vacant FM channels are not in compliance with the minimum distance separation requirements of the Federal Communications Commission (Commission) rules, and vacant Channel 261B at Coalinga is also not in compliance with the city-grade coverage requirements of the Commission's rules. The window period for filing applications for these vacant FM allotments will not be opened at this time. Instead, the issue of opening these allotments for filing will be addressed by the Commission in subsequent order. See Supplementary Information.
This document amends the Table of FM Allotments, of the Federal Communications Commission's (Commission) rules, by removing certain vacant FM allotment channels that were auctioned through our FM competitive bidding process and are no longer considered vacant FM allotments. The FM allotments are currently authorized licensed stations. FM assignments for authorized stations and reserved facilities will be reflected solely in Media Bureau's Licensing Management System (LMS). These FM allotment channels have previously undergone notice and comment rule making. This action constitutes an editorial change in the Table of FM Allotments. Therefore, we find for good cause that further notice and comment are unnecessary.
In this document, the Federal Communications Commission (Commission or FCC) proposes to modify the Commission's rules to implement certain spectrum allocation decisions from the International Telecommunication Union's World Radiocommunication Conference's 2019 Final Acts concerning portions of the radio spectrum between 495 kHz and 50.9 GHz, make other allocation changes, and make related updates to our service rules in this frequency range. These proposals are designed to harmonize our spectrum allocations with and conform our rules to the World Radiocommunication's 2019 Final Acts to the extent that doing so would better meet domestic requirements.
In this document, the Federal Communications Commission (Commission or FCC) modifies the United States Table of Frequency Allocations (U.S. Table) in the Commission's rules to implement certain spectrum allocation decisions from the International Telecommunication Union's World Radiocommunication Conference's 2015 Final Acts, including those for amateur radio, satellite services, and for aural broadcast auxiliary and television broadcast auxiliary stations by revising the Commission's rules. These changes provide for increased domestic utilization of a range of spectrum in both satellite and terrestrial contexts.
In July 2025, President Trump signed the One Big Beautiful Bill Act. Section 40002 of that law re-institutes the Federal Communications Commission's general auction authority and specifically directs the Commission to complete a system of competitive bidding for not less than 100 megahertz in the 3.98-4.2 gigahertz band (Upper C- band). To ensure safe, efficient, and reliable aviation operations in the presence of wireless signals in the Upper C-band, the Federal Aviation Administration is proposing new regulations that would require all radio altimeters to meet specific minimum performance requirements. These new radio altimeters must withstand interference from wireless signals in neighboring spectrum bands and continue to provide accurate altitude readings to both pilots and integrated aircraft safety systems. The minimum interference tolerance requirements proposed in this rule reflect the best achievable interference rejection using current technology without compromising radio altimeter system performance. These regulations would require all aircraft equipped with radio altimeters operating under part 121 and those aircraft with radio altimeters operating under part 129 with 30 or more passenger seats or a payload capacity of more than 7,500 pounds to comply with the minimum performance requirements by the date the Federal Communications Commission authorizes wireless services in the Upper C-band. All other aircraft equipped with radio altimeters would be required to comply with the same minimum performance requirements two years later. This proposed rule is a companion to the Federal Communications Commission's NPRM to expand the ecosystem for next-generation wireless services in the 3.7-4.2 gigahertz band by making as much as 180, and at least 100, megahertz of the Upper C-band available for terrestrial wireless flexible use via a system of competitive bidding.
This document amends the Table of FM Allotments, of the Federal Communications Commission's (Commission) rules, by reinstating certain channels as a vacant FM allotment in various communities. The FM allotments were previously removed from the FM Table because a construction permit and/or license was granted. These FM allotments are now considered vacant because of the cancellation of the associated FM authorizations or the dismissal of long-form auction FM applications. A staff engineering analysis confirms that all of the vacant FM allotments complies with the minimum distance separation requirements and principle community coverage requirements of the Commission's rules. The window period for filing applications for these vacant FM allotments will not be opened at this time. Instead, the issue of opening these allotments for filing will be addressed by the Commission in subsequent order.

The existing vacant FM channels are not in compliance with the minimum distance separation requirements of the Federal Communications Commission (Commission) rules, and vacant Channel 261B at Coalinga is also not in compliance with the city-grade coverage requirements of the Commission's rules. See Supplementary Information.
This document amends the Table of FM Allotments, of the Federal Communications Commission's (Commission) rules, by removing Channel 285A at Adamsville, Texas and by adding Channel 285A at Richland Springs, Texas. The staff engineering analysis determines that Channel 285A can be allotted to Richland Springs consistent with the minimum distance separation requirements of the Commission's rules, with a site restriction of 12 kilometers (7.5 miles) southeast of the community. The reference coordinates are 31-10-24 NL and 98-53-25 WL.
The Food and Drug Administration (FDA) is making technical amendments to its radiological health regulations to correct an error. On January 20, 2023, FDA published a final rule entitled "Radiological Health Regulations; Amendments to Records and Reports for Radiation Emitting Electronic Products; Amendments to Performance Standards for Diagnostic X-ray, Laser, and Ultrasonic Products" that inadvertently deleted certain existing regulatory text from the Code of Federal Regulations. This action corrects the error by restoring the inadvertently deleted regulatory text. This action is editorial in nature and is intended to ensure accuracy and clarity in FDA's regulations by restoring inadvertently deleted regulatory text.

In this document, the Federal Communications Commission (Commission or FCC) adopted a Notice of Proposed Rulemaking (NPRM), in which it seeks comment on or proposes updates to set clear expectations about the Commission's review in both common carrier and broadcast licensees and on other updates that apply only to broadcast licensees. With regard to common carrier licensees, the NPRM seeks comment on or proposes to amend the rules to codify existing policy regarding which entity is the controlling U.S. parent; codify the Commission's advance approval policy regarding certain deemed voting interests; require identification of trusts and trustees; extend the remedial procedures and methodology to privately held companies; add requirements regarding the contents of remedial petitions; require the filing of amendments as a complete restatement to petitions for declaratory ruling; and clarify U.S. residency requirements. For broadcast licensees only, the NPRM seeks comment on how the Commission should process applications filed by a broadcast licensee during the pendency of a remedial petition for declaratory ruling; and other foreign ownership considerations related to processing applications for NCE and LPFM stations. The NPRM proposes to make it easier for entities to understand and navigate the FCC's foreign ownership rules. The FCC believes that this proceeding will avoid inconsistent outcomes; reduce costs; and facilitate the Commission's public interest analysis.

In this document, the Federal Communications Commission (Commission) makes available 600 megahertz of high-frequency spectrum for flexible fixed and mobile use by establishing a mechanism for access to the 37-37.6 GHz band (Lower 37 GHz band). This spectrum, which is shared between non-Federal and Federal operators, can be used for fixed wireless broadband, Internet of Things (IoT), or other innovative services. Crafted in collaboration with the National Telecommunications and Information Administration (NTIA) and with input from the Department of Defense (DoD), this new regime provides access to a block of millimeter wave spectrum with low barriers to entry.
In this document, the Federal Communications Commission (Commission) seeks comment on three issues: adopting a more stringent emissions limit for Upper Microwave Flexible Use Service (UMFUS) operations above 37 GHz; whether the first phase of the coordination mechanism adopted in the companion final rule, published elsewhere in this issue of the Federal Register, can be enhanced by consideration of additional factors; and whether it might be possible to replace the same coordination mechanism with a dynamic spectrum management system (DSMS). The Commission also proposes to correct an error in a power flux density (PFD) figure in one of its technical rules for UMFUS.
The Food and Drug Administration (FDA, the Agency, or we) is classifying the radiological acquisition and/or optimization guidance system into class II (special controls).
