Differentiate between Wireless Emergency Alerts (WEA) and the Emergency Alert System (EAS).

• A. WEA sends geo-targeted alerts to mobile devices; EAS delivers alerts through broadcast channels (radio/TV) to wide audiences.
• B. WEA sends alerts through radio/TV; EAS uses mobile devices.
• C. WEA is for weather data; EAS is for all emergencies.
• D. WEA and EAS are interchangeable.

Answer: (A)

Wireless Emergency Alerts target people where they are by pushing short messages to mobile devices over the cellular network in a defined geographic area. This system is built for speed and specificity, so someone in a specific neighborhood or region receives the alert even if they aren’t watching TV or listening to the radio. The messages are concise and designed to wake mobile screens quickly, covering events like severe weather, missing persons (AMBER alerts), or other imminent threats.

Emergency Alert System, on the other hand, uses traditional broadcast channels—radio, television, and related platforms—to reach a broad audience. It’s built for wide dissemination, often at a national or regional scale, and doesn’t rely on mobile networks. The EAS is typically used for official alerts issued by authorized authorities that need to be heard by large numbers of people across many communities.

So, the best distinction is that Wireless Emergency Alerts push geo-targeted notices to mobile devices, while the Emergency Alert System delivers alerts through broadcast channels to broad audiences.
