In the province of Tyrol, a digital radio relay network ensures the connection of the individual districts and the transmission of data relevant to alerting in the event of a disaster. This way, communication and help can still be coordinated between valleys cut off by avalanches. The disaster directional radio network forms the backbone for the digital radio warning and alerting system networks.

When planning the network, particular attention was therefore paid to stability, fail-safety and redundancy: There are currently 128 lines in operation, providing fail-safe data transmission over a distance of up to 50 km. The use of underground pipelines was deliberately avoided in order to prevent any damage from landslides.
