{"abstract":"In this document, the Federal Communications Commission (Commission) revises the Wireless Emergency Alerts (WEA) rules to allow alert originators the option to send \"silent alerts\" that do not trigger WEA's common audio attention signal or vibration cadence. This action grants alert originators greater flexibility in tailoring how WEA messages are presented. Further, to make as clear as possible to the public that any device marketed as a \"WEA-capable mobile device\" adheres to the full suite of WEA capabilities, the Commission also adopts its proposals to define a \"WEA-capable mobile device,\" for the purpose of compliance with the Commission's WEA requirements.","action":"Final rule.","agencies":[{"raw_name":"FEDERAL COMMUNICATIONS COMMISSION","name":"Federal Communications Commission","id":161,"url":"https://www.federalregister.gov/agencies/federal-communications-commission","json_url":"https://www.federalregister.gov/api/v1/agencies/161","parent_id":null,"slug":"federal-communications-commission"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2025/03/18/2025-04126.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"10","title":47}],"citation":"90 FR 12462","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"The definitions of a WEA-capable mobile device and a mobile device for the purpose of WEA (section 10.10(j) through (m)), along with conforming edits (to the introductory text of section 10.500, section 10.500(i) through (j), the introductory text of section 10.520, and the introductory text of section 10.530), will become effective September 15, 2025.
