DAB+ stations whose programme feed is interrupted due to interference receive the programme terrestrially from another DAB+ station, convert it to a different frequency (channel) and broadcast it again with a short time delay. The programme that has been distributed in this way can now be received by other DAB+ stations and broadcast on a different frequency. In this way, comprehensive broadcasting coverage can be achieved even in the event of a disaster. Manufacturers of receivers and receiver chips, as well as the automotive industry, are invited to test their receivers with regard to re-broadcasting.

The EWF Emergency Warning Functionality is a combination of different services such as Alarm Announcement, Service Linking, Program Associated Data and Non-PAD, and can distribute multimedia and multilingual information. The EWB procedure is also compatible with all old DAB receivers. Modern receivers are also switched on automatically with EWB and can display information via other data services.

A warning system developed by Fraunhofer IIS called EWF (Emergency Warning Functionality) for DAB+ digital radio devices could have warned people of disasters, even if the radio was switched off. If mobile internet fails, warning messages can no longer be received via smartphones.

If a disaster occurs, the mobile phone networks are quickly overloaded or no longer available. The public must therefore be informed via an independent infrastructure. DAB offers a robust and well-established transmission network and simple (battery-powered) DAB receivers are sufficient for reception. In addition, DAB broadcasts are unencrypted and freely available and can reach the entire population. DAB is therefore very well suited for transmitting emergency warning information.

Thanks to DAB + digital radio, the Emergency Warning Functionality (EWF) can be used to send corresponding warnings directly to DAB + radio devices. EWF is a new form of barrier-free alerting within a few seconds, which the digital terrestrial broadcasting standard DAB + offers and, in exceptional cases, can switch on radios that are in standby. In addition to the voice announcement, multilingual text information is also transmitted with EWF via DAB+.
