Siqens: Province of Tyrol: Security of supply of critical radio networks
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.
For the mostly alpine locations, a combination of photovoltaics and battery for independent power supply is suitable. Thus, a full battery charge ensures operation for at least 48 hours. However, additional measures are often required to ensure a weather-independent, year-round energy supply to critical sites.
For this reason, the SIQENS Ecoport 800 is used at the deflection point on the Messelingkogel at an altitude of just under 2,700 meters. The energy from the fuel cell is sufficient to power a small electric heater in addition to the connected directional antennas. This is used when de-icing the plant in winter. The connected tank with 200 litres of methanol provides enough energy to run the site self-sufficiently for several months.
