Wireless Emergency Alerts (WEA) from Comtech Location Technologies

We offer a fully integrated end-to-end WEA/CMAS solution trusted by alert originators, authorities, and Mobile Network Operators.

Wireless Emergency Alerts, or WEA (also known as Commercial Mobile Alerts System (CMAS) in the US), is a government-mandated system that enables authorized officials to inform the public about life-threatening events by automatically delivering emergency alerts to mobile devices (including roaming users) via the government alert gateway.

Our patented technology facilitates the origination and accurate delivery of geo-targeted emergency alerts, empowering emergency services providers to better serve the public. Mobile Network Operators are able to quickly broadcast emergency alerts to all devices in a specific geographical area. Our solution uses standardized infrastructure, ensuring compliance with government regulations in Europe, the Middle East, Asia, and globally.

Components of Our WEA Solution

Commercial Mobile Service Provider (CMSP) Gateway

A secure, concentrated point of access to the Federal Alert Gateway and potentially to other future external entities, third parties, or value-added service providers.

Cell Broadcast Center (CBC)

Component that maps alert areas into appropriate network coverage and facilitates alert delivery via cellular networks (2G, 3G, 4G, and 5G).


Comprehensive element management system to facilitate operations, administration, and maintenance for both the CMSP Gateway and the Cell Broadcast Center.
