DA 25-1099 Released: December 22, 2025 OFFICE OF ENGINEERING AND TECHNOLOGY SEEKS COMMENT ON ULTRA-WIDEBAND DEVICE PETITION FOR RULEMAKING RM No. 12014 Comments Due: January 30, 2026 Reply Comments Due: February 27, 2026 By this Public Notice, the Office of Engineering and Technology seeks comment on a petition for rulemaking by the Alliance for Automotive Innovation, Car Connectivity Consortium, FiRa Consortium, Profibus & Profinet International / omlox, and the UWB Alliance (together, the UWB Petitioners) requesting the Commission initiate an expedited proceeding to amend certain portions of the FCC’s part 15 rules to allow for more flexible ultra-wideband (UWB) device operations. UWB Petitioners Petition for Rulemaking, filed on December 18, 2025, available at https://www.fcc.gov/ecfs/search/search-filings/filing/1218228512214 (UWB Petition). In its petition, the UWB Petitioners ask the Commission to: · Delete “at any point in time” from the definition of UWB to allow for devices that operate with modulations other than pulsed based without posing significant interference risk and to eliminate the requirement to develop a special test mode that does not represent normal UWB operations; · Adopt a definition of “fixed outdoor infrastructure” to clarify when UWB devices may not be affixed to objects; · Eliminate use of the term “hand held” in Section 15.519 of the Commission’s rules to ensure the UWB rules account for the wide array of non-fixed, affixed, and vehicle-mounted UWB-enabled devices that can provide short-range services consistent with the intent of the Commission’s rules; · Allow a duty cycle requirement as an alternative to the 10-second rule to support more efficient deployment of UWB technology; and · Allow UWB to be used in toys and aboard vessels within inland waters given the lack of interference risk and increasingly ubiquitous deployment of UWB technology in consumer devices. Id. at 7-8 and Appendix B (proposed rule changes). Additional Issues: The Office of Engineering and Technology seeks comment on any other portions of the FCC’s part 15 rules that could be amended to update the Commission’s UWB regulatory framework.

Ex Parte Rules. The proceeding this Public Notice initiates shall be treated as a “permit-but-disclose” proceeding in accordance with the Commission’s ex parte rules. 47 CFR § 1.1200 et seq. Persons making ex parte presentations must file a copy of any written presentation or a memorandum summarizing any oral presentation within two business days after the presentation (unless a different deadline applicable to the Sunshine period applies). Persons making oral ex parte presentations are reminded that memoranda summarizing the presentation must (1) list all persons attending or otherwise participating in the meeting at which the ex parte presentation was made, and (2) summarize all data presented and arguments made during the presentation. If the presentation consisted in whole or in part of the presentation of data or arguments already reflected in the presenter’s written comments, memoranda or other filings in the proceeding, the presenter may provide citations to such data or arguments in his or her prior comments, memoranda, or other filings (specifying the relevant page and/or paragraph numbers where such data or arguments can be found) in lieu of summarizing them in the memorandum. Documents shown or given to Commission staff during ex parte meetings are deemed to be written ex parte presentations and must be filed consistent with section 1.1206(b). In proceedings governed by section 1.49(f) or for which the Commission has made available a method of electronic filing, written ex parte presentations and memoranda summarizing oral ex parte presentations, and all attachments thereto, must be filed through the electronic comment filing system available for that proceeding, and must be filed in their native format (e.g., .doc, .xml, .ppt, searchable .pdf). Participants in this proceeding should familiarize themselves with the Commission’s ex parte rules. People with Disabilities.
