WEA - System Enhancement Recommendations

This document describes several recommended enhancements for the operation, performance, and maintenance of the Wireless Emergency Alerts (WEA), formerly known as the Commercial Mobile Alert Service (CMAS). The recommendations are partially based on the results of a previous Computer Model and Simulation Results study undertaken as part of the WEA Program at The Johns Hopkins University Applied Physics Laboratory for the U.S. Department of Homeland Security (DHS) Science and Technology Directorate (S&T). In addition to this study, potential use cases of WEA and engineering best practices for secure and highly reliable systems were considered for inclusion in this document.

The following system enhancements are recommended for the WEA system. The rationale for each of these recommendations is described in the main body of this document, along with an overview of the recommended solutions and potential benefits. Implementation details of the recommended solutions are not described in depth in this document, but are deferred for future consideration.
