Wireless Emergency Alerts

Comtech’s fully integrated end-to-end Wireless Emergency Alert (WEA) solution is trusted by the world’s leading alert originators, authorities, and mobile network operators. 

WEA is a system that enables authorized officials to inform the public about life-threatening events by connecting emergency mobile alert systems to the government alert gateway.

Comtech Trusted Alerting System

The Comtech Trusted Alerting System (CTAS) provides a CMSP gateway
and Cell Broadcast Center (CBC) for WEA service.

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 wireless network coverage and facilitates alert delivery via cellular networks (2G, 3G, 4G, and 5G).

Operation Graphical User Interface (GUI): Comprehensive element management system to facilitate operations, administration, and maintenance for both the CMSP Gateway and the CBC. 


Standard Interface Compliance: CTAS is fully compliant with ATIS and 3GPP specifications, enabling standard connectivity between the IPAWS’s Federal Alert Gateway, and mobile network operators’ radio access networks.
