This week, Metis Secure Solutions announced the completion of a project funded by FEMA to illustrate the effectiveness of sending emergency alerts through the FM Radio Broadcast Data System (RBDS) method. RBDS is a U.S. radio industry standard for transmitting digital information to radio receivers. It's the technology that drives your ability to see song/artist information on a car radio, and can be used to deliver other types of data such as emergency alert messages.
There were four tests--one of them originating with the common alerting protocol (CAP) format. Each alert activated voice, text, lights and sirens (these devices are capable of receiving and interpreting the radio signal). Alert text was sent in English and Spanish, and the alert voice was activated in English, Spanish, and Korean.
Typically, mass notification systems rely on Internet protocols or mobile phone networks. It will be interesting to see what future applications emerge as this radio-oriented concept continues to gain traction.
Best regards,
