On August 14, 2026, the FCC's Wireless Telecommunications Bureau (WTB) and Office of Engineering and Technology (OET) released Public Notice DA-26-853 opening a public comment window on petitions for reconsideration or clarification filed by CTIA in GN Docket No. 26-74. The petitions target earlier C-UAS (counter-unmanned aircraft systems) actions taken by the two bureaus, which set the conditions under which counter-drone detection and mitigation equipment can operate in radio spectrum. Comments are due September 14, 2026, with reply comments due September 29, 2026.
The notice does not launch a fresh rulemaking. It asks stakeholders to weigh in on whether the bureaus should revise or clarify how C-UAS systems are authorized to detect, locate, and mitigate hostile drones, and specifically how those operations interact with licensed wireless spectrum. Because CTIA, the trade group for the largest US wireless carriers, is the petitioner, the proceeding turns directly on whether counter-drone equipment may cause harmful interference to licensed mobile operations. The official Public Notice (DA-26-853) and its attachments are available on the FCC document page.
What did the prior C-UAS actions do, and what is CTIA challenging?
The WTB and OET had previously taken actions in GN Docket 26-74 to enable C-UAS detection and mitigation systems, recognizing that critical-infrastructure operators, airports, prisons, and security agencies need technical means to detect and defeat hostile drones. Those actions addressed how counter-drone equipment can transmit and receive radio signals to find, track, and disrupt unmanned aircraft.
CTIA's petitions for reconsideration or clarification argue that the prior actions need correction or sharper definition, chiefly around the interference exposure of licensed spectrum. Carriers hold exclusive use rights in their licensed bands, and any C-UAS system that radiates in or near those bands, whether to sense drones or to jam them, can degrade mobile service. The petitions ask the bureaus to reconsider the conditions they imposed and to clarify what C-UAS operators must do to protect licensed operations.
Who must engage, and by what deadline?
Three groups have a direct stake and should file, not just watch. US wireless carriers (AT&T, Verizon, and T-Mobile, all CTIA members) face the interference risk and are effectively the beneficiaries of the petitions. C-UAS technology vendors that build detection, tracking, and mitigation hardware face potential new operating constraints or authorization conditions on their products. Critical-infrastructure security operators, including airports, energy utilities, stadiums, and military-adjacent sites, depend on C-UAS authority to defend their facilities and may lose operational flexibility if the rules tighten.
The deadline ladder is short:
| Milestone | Date | What is due |
|---|---|---|
| Public Notice released | August 14, 2026 | Comment window opens |
| Comments due | September 14, 2026 | Initial positions and evidence |
| Reply comments due | September 29, 2026 | Responses to other parties |
What spectrum and product-authority stakes are on the table?
The proceeding touches two distinct compliance risks. First, spectrum interference: if the bureaus clarify that C-UAS systems may radiate only under narrower conditions, or impose stronger protection duties for licensed bands, vendors must redesign detection and mitigation RF front ends and operators must re-certify their deployments. Second, product authority: C-UAS equipment is authorized through the FCC equipment authorization framework (47 CFR Part 2 and Part 15), so a change in the operating conditions these products were certified against can reset their market-access basis and force new certifications.
For carriers, the stakes run the other way: weaker interference protections could let counter-drone transmissions degrade licensed mobile service, triggering quality and reliability obligations. Both sides therefore have concrete reasons to file before September 14.
Continuous, per-jurisdiction monitoring of FCC dockets surfaces a consultation like this the moment it publishes, rather than after a commenter has already framed the record.

What to do next
- Verify applicability: confirm whether your organization operates, deploys, or supplies C-UAS detection or mitigation equipment, or holds licensed spectrum exposed to counter-drone transmissions.
- Calendar the deadlines: file comments by September 14, 2026 and reply comments by September 29, 2026 in GN Docket 26-74 via the FCC Electronic Comment Filing System (ECFS).
- Scope the technical record: review the prior WTB and OET C-UAS actions and identify the specific operating conditions or certification bases the CTIA petitions would change.
- Brief the right team: pull in spectrum engineering, equipment authorization, and physical-security stakeholders so the filing reflects both the RF and the operational perspective.
Obsidian tracks this docket alongside the wider US equipment-authorization and drone-regulation landscape, so compliance teams can act on the next shift, whether a clarification, a revised authorization condition, or a new rule, without losing the thread.
