Wireless Emergency Alerts on Your Mobile Device

The Commercial Mobile Alert System (CMAS) is the system interface to the Wireless Emergency Alerts (WEA) service that wireless carriers are rolling out across the nation in 2012. CMAS is a partnership between FEMA, the Federal Communications Commission (FCC), and wireless carriers, to enhance public safety.

CMAS allows public safety authorities to send geographically targeted, text-like Wireless Emergency Alerts to the public. WEAs will relay Presidential, AMBER, and Imminent Threat alerts to mobile phones using cell broadcast technology that will not get backlogged during times of emergency when wireless voice and data services are highly congested.

CMAS/WEA complements the existing Emergency Alert System (EAS) which sends warnings to television and radio via broadcast, cable, satellite, and wireline communications pathways. IPAWS CMAS is operational now and all major cell carriers, as well as hundreds of smaller carriers, are participating in CMAS on a voluntary basis.
