Abstract

The Wireless Emergency Alerts (WEA), formerly known as the Commercial Mobile Alert Service (CMAS), is a national capability for delivering geographically targeted alerts to the public on mobile devices. The WEA service transmits three types of alerts: presidential alerts, imminent threat alerts, and America’s Missing: Broadcast Emergency Response (AMBER) alerts.  

WEA is part of the Federal Emergency Management Agency’s Integrated Public Alert and Warning System (IPAWS). IPAWS will modernize the nation’s alert infrastructure and add new ways to warn people of imminent threats. WEA integrates mobile phones and the internet with traditional Emergency Alert System radio and television broadcasts.

The Department of Homeland Security  Directorate for Science and Technology worked with several industry and academic partners to develop, test, and evaluate WEA. The SEI researched the challenges of guiding alert originators in how to integrate into WEA. This effort produced nine reports.
