About Wireless Emergency Alerts

Comtech’s Wireless Emergency Alerts (WEA) solution is an Industry Standards based solution using our patented technology which facilitates the origination and accurate delivery of geo-targeted emergency alerts. Comtech Telecommunications Corp. provides a fully integrated end-to-end WEA solution that alert originators, authorities and carriers trust. Building on the company’s standing as a premier provider of public safety solutions, we’ve been operating our emergency alert and wireless public safety platform for nearly a decade.

Also known as Commercial Mobile Alerts System (CMAS) in the US, the system enables authorized government officials to deliver emergency mobile alerts to keep the public informed about life-threatening events.

Comtech Telecommunications has been actively involved in WEA-related standards working sessions since January 2008 and our WEA technology provides carriers an easy-to-implement, fully-compliant and FEMA-certified solution.

Our solution consists primarily of the following components:

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 (i.e., broadcast zones, list of cell sites or the area freely defined by the operator) and facilitates alert delivery via the cellular networks (CDMA, GSM, UMTS and LTE) to the intended handsets / subscribers


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

Features Benefits
Carrier interface compliance
  • Fully compliant with “C” interface message scenarios and protocol per JCMAS standards (ATIS/TIA Joint J-STD-101)
  • Assured interoperability with centralized federal/alert gateway such as FEMA Gateway for the US and Pelmorex NAADS for Canada
Unique Capabilities
  • Alert delivery via geo-targeted SMS and Email (beyond cell broadcast)
  • Test tool to issue targeted alerts
  • Cell site data import tool
  • Multi-channel alert delivery
  • Reduced operational expenditure to test WEA in live network post events like network migration, software upgrades, handset launch etc.
  • Automated processing of cell site data changes
Interoperability with network equipment providers
  • Proven interoperability with BSCs, RNCs and MMEs from Ericsson, Huawei, Alcatel Lucent, and Nokia
  • Reduced risk and implementation costs
  • Rapid implementation of WEA on your network
Accurate Geo-Targeting
  • County, Sub-county and polygon schemes
  • Unique ability to utilize RF coverage data for enhanced geo-targeting – best approximation of alert polygon issued by the Alert Originator (Output of US DHS Research Project)
  • Our thought leadership with geo-targeting makes the solution future proof
  • More accurate geo-targeting is part of the US FCC’s requirements for next gen WEA
Support for all radio technologies
