DAB+ emergency broadcasting and warnings
- DAB+ radio broadcasting can play a critical role in times of emergency
- DAB+ emergency warning feature enables real time messaging to alert communities of emergency and recovery situations
- Deployment of the DAB+ emergency warning feature requires the establishment of implementation protocols developed with relevant authorities
The DAB+ emergency warning feature – Alarm Announcement Switching (AAS) - provides the ability to redirect DAB+ receivers to play out a predefined radio service which delivers emergency information, advice and directions.
An EU Directive (EECC ) effective from December 2020 requires that all domestic and in-vehicle DAB+ receivers in Europe must include DAB+. The DAB+ Minimum Requirements technical standard requires that all receivers include the DAB+ emergency warning feature - Alarm Announcement Switching (AAS). As Europe drives the receiver market and most receivers delivered to other parts of the world are derived from those products, the AAS feature will effectively be included in receivers worldwide from 2020.
