This document discusses using digital broadcast technologies like FM/RDS and mobile DTV for public alerting on smartphones. It summarizes CRC's work developing an FM radio application called FM TwoO for Android phones that demonstrates receiving emergency alerts over FM/RDS. While FM/RDS has good penetration, smartphone integration is inconsistent. Mobile DTV has potential for multimedia alerts but has no penetration currently in Canada. CRC could contribute to standardizing alert formats, coverage planning, testing, and field trials using these broadcast technologies for public alerts on mobile devices.
