Comtech Trusted Alert System from Comtech Trusted Location

CTAS is Comtech's fully integrated end-to-end WEA solution trusted by alert originators, authorities, and mobile network operators.

Wireless Emergency Alerts, or WEA (formally 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 can quickly broadcast emergency alerts to all devices in a specific geographical area. Our solution fully complies with ATIS and 3GPP standards, ensuring compliance with government regulations.

Comtech offers a complete end-to-end solution to the WEA system.



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. This component is also known as Cell Broadcast Entity (CBE).

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. This system also includes WEA elements testing tool, cell coverage viewing, and alert area viewing tool.
