from the FCC Communications Security, Reliability and Interoperability Council (CSRIC) and investigated enhancing cell broadcast geo-targeting for WEA alerts; providing supplemental information for a WEA alert; and increasing the WEA alert message length. The first study looked into methods for the delivery of geo-targeted WEA messages to a given geocode, circle or polygon, and concluded that the current wireless infrastructure-based geotargeting continues to be the recommended solution for WEA geotargeting. ATIS also studied the practicality, limitations and effects of providing supplemental information for a WEA alert to a mobile device and enabling a mobile device to display supplemental information. The study said multimedia content can't be supported in today's cell broadcast-based WEA system. The study of WEA message length confirmed that an increase in the maximum displayable characters is technically feasible for an LTE WEA message.
