FCC Seeks Beefier Wireless Doomsday Alerts System
Published Date: 7/31/2026
Proposed Rule
Summary
In this document, the Federal Communications Commission ("FCC" or "Commission") adopted a Further Notice of Proposed Rulemaking that seeks comment on proposed rules intended to make the Emergency Alert System (EAS) and Wireless Emergency Alerts (WEA) more resilient, flexible, and useful.
Analyzed Economic Effects
8 provisions identified: 5 benefits, 0 costs, 3 mixed.
Require CAP Alerts to Be Signed
The FCC proposes requiring EAS Participants to reject Common Alerting Protocol (CAP) Emergency Alert System messages that do not include a valid digital signature. The NPRM notes that more than 2,000 federal, state, local, tribal, and territorial alerting authorities use FEMA's IPAWS, which digitally signs alerts, and asks for comment on impacts to non-IPAWS systems.
Authenticate Legacy EAS Alerts
The FCC seeks comment on requiring digital signatures or other authentication for legacy EAS alerts sent using the EAS Protocol. The NPRM cites CSRIC VI analysis that adding a 2048-bit digital signature could add about 8.6 seconds to validation and processing and asks how that delay, multiplied in daisy-chain rebroadcasts, would affect timely delivery.
Universal Alert Message ID to Stop Duplicates
The FCC proposes that Participating Commercial Mobile Service (CMS) Providers use a common "universal alert message ID" assigned to each Wireless Emergency Alert (WEA) message so mobile devices can identify and suppress duplicate alerts. The proposal references IPAWS-assigned unique IDs and seeks comment on shortening or hashing them for use in WEA metadata.
WEA Rebroadcast Every 60 Seconds
The FCC seeks comment on requiring Participating CMS Providers to rebroadcast each WEA message at least once every 60 seconds throughout an alert's active period. The NPRM notes that at least one major provider already rebroadcasts every 60 seconds and that some commenters supported one-minute intervals.
Eliminate Legacy Geotargeting Exceptions
The FCC proposes eliminating existing WEA geotargeting exceptions that allow more than 0.1 mile of overshoot for legacy networks/devices and other circumstances, and would require delivery to "100 percent of opted-in WEA-capable mobile devices that are connected to its network and located in the Alert Message's target area." The NPRM notes many providers are retiring 2G/3G networks.
Turn On Location Services for WEA (With Safeguards)
The FCC proposes eliminating the geotargeting exception for devices with location services disabled and seeks comment on requiring devices to turn on location services when a WEA is received (similar to 911), while prohibiting use of that location information for non-WEA purposes, prohibiting transmission of the location over networks, and deleting the location data immediately after geofencing.
FIPS‑Code Alerts Must Match Polygon Accuracy
The FCC proposes requiring WEA messages that geotarget using FIPS county codes (geocodes) to achieve the same accuracy limit as messages using polygons or circles (no more than 0.1 mile overshoot). The NPRM notes the U.S. Census Bureau now publishes county-to-polygon mappings that may enable conversion.
Stop WEA Retransmission Near 24‑Hour End
The FCC seeks comment on requiring Participating CMS Providers to cease retransmission of WEA messages with a 24-hour active period five minutes before that period ends, to mitigate duplicate-display issues caused by devices purging old alerts.

2026-18535, Protecting Against National Security Threats to the Communications Supply Chain Through the Equipment Authorization Program
In this document, the Federal Communications Commission (Commission or FCC) takes further steps to strengthen its equipment authorization program against national security risks to the communications supply chain. The Commission closes a component-part loophole by prohibiting authorization of devices that incorporate logic-bearing hardware components produced by an entity identified on the Commission's Covered List, where the device would itself be prohibited from authorization had the Covered List entity produced the entire device. The Commission also requires that any modification or permissive change to equipment by an entity identified on the Covered List undergo full certification, clarifies that its marketing rules reach any entity (including online marketplaces) that markets unauthorized equipment, and requires online marketplaces, subject to limited exceptions, to display a device's FCC ID at the online point of sale. Finally, the Commission amends its definition of "critical infrastructure," as used on the Covered List, and corrects two administrative errors in its rules.
2026-18411, Information Collection Being Reviewed by the Federal Communications Commission Under Delegated Authority
As part of its continuing effort to reduce paperwork burdens, and as required by the Paperwork Reduction Act of 1995 (PRA), the Federal Communications Commission (FCC or Commission) invites the general public and other Federal agencies to take this opportunity to comment on the following information collections. Comments are requested concerning: whether the proposed collection of information is necessary for the proper performance of the functions of the Commission, including whether the information shall have practical utility; the accuracy of the Commission's burden estimate; ways to enhance the quality, utility, and clarity of the information collected; ways to minimize the burden of the collection of information on the respondents, including the use of automated collection techniques or other forms of information technology; and ways to further reduce the information collection burden on small business concerns with fewer than 25 employees.

The FAA wants to update safety checks on CFM56-7B airplane engines by improving how fan blades are inspected for cracks. This means airlines must do better and more thorough inspections and replace any cracked parts to keep flights safe. Comments on this plan are open until August 31, 2026, and these changes could affect maintenance schedules and costs.

This action proposes to amend Jet Route J-24 and Very High Frequency Omnidirectional Range Federal (VOR) Airways V-244 and V-508 and revoke VOR Federal Airway V-255 in the vicinity of Hays, Kansas. The FAA is proposing this action due to the planned decommissioning of the VOR portion of the Hays, KS, VOR/Tactical Air Navigation (VORTAC) navigational aid (NAVAID). The VOR portion of this NAVAID is being decommissioned as part of the FAA's VOR Minimum Operational Network (MON) program. The TACAN portion of this NAVAID will be retained.
