Based on the IDAS system, Tunnelkom GmbH was awarded a contract for the renaturation of several tunnels.

There were several challenges that had to be mastered.

Of the 3 tunnels, 2 were each 1km long and 1 tunnel 7km long. Each of the workers had to be able to take their radio from one tunnel to the other and communicate smoothly. 

Regardless of the infrastructure, there should also be a redundant level on which the workers should be able to communicate with each other. 


For this purpose, a special RF link was developed by Icom (Europe) GmbH for the 7km long tunnel.

As there was no power supply in the tunnels, fuel cells were used to ensure uninterrupted operation of the communication infrastructure.

In total, 12 repeaters and over 120 handheld radios were used for the job.
