The ubiquity of mobile devices provides new opportunities to warn people of emergencies and imminent threats using location-aware technologies. The Wireless Emergency Alerts (WEA) system, formerly known as the Commercial Mobile Alert Service (CMAS), is the newest addition to the Federal Emergency Management Agency (FEMA) Integrated Public Alert and Warning System (IPAWS), which allows authorities to broadcast emergency alerts to cell phone customers with WEA-enabled devices in an area affected by a disaster or a major emergency. This blog posting describes how the Software Engineering Institute's (SEI) work on architecture, integration, network security, and project management is assisting in implementing the WEA system, so it can handle a large number of alert originators and provide an effective nationwide wireless emergency warning system.
