Press release

Swisscom demonstrates its expertise in the Glacier Patrol

Berne, 16 April 2008

Swisscom is involved in the Glacier Patrol for the second time and will ensure seamless mobile coverage along the entire route during the alpine competition. In addition, 400 event participants, organisers and course monitors will receive a mobile phone from Swisscom.

Swisscom began planning the temporary mobile network one year ago. Six network elements were designed on a computer and then defined using on-site measurements. Swisscom was supported by the army in this process. Because setting up a temporary network in the Valais Alps is not just routine work but a major challenge. The terrain makes transport of the equipment more difficult and the low temperatures affect how efficiently the equipment functions.


Cooperation between Swisscom and the Swiss Army

Swisscom is working closely with the Glacier Patrol command to tackle this challenging task. Power supply and transport, for example, are provided by the army. A core team of eight Swisscom employees was involved in planning and supported by around 40 members of the military in the setup phase. During the competition, 34 people from the army's telecommunication division will be deployed to monitor the mobile network.


Increased safety with monitoring posts and prioritisation

The infrastructure at the command post in Arolla enables the mobile network to be monitored 24 hours a day. Capacity overloads or faults can be quickly located and suitable measures undertaken immediately. Safety is important to Swisscom. Which is why calls from the patrol mobile phones will be prioritised in the network, meaning that they will be connected first. The Swisscom mobile network replaced the old SE-125 military network in 2006.


Temporary network

Three temporary GSM base stations were implemented this year for the Glacier Patrol. On the Dent Blanche (3507m), on "Barma" (2458m) and on the Mont Fort cable car (3308m). All three base stations are connected to a military radio link. Three repeaters were also installed for the race to route the received signals on the "TĂȘte Blanche" (3724 m) , the "Bertol" (3311m) and "La Rosablanche" (3277m). The two "Unterrothorn" sites at Zermatt and Arolla are now permanently in operation. Both the local population and the tourists benefit.


On-site presence
