Every other year, the legendary Patrouille des Glaciers takes place between Zermatt and Verbier. This event is organized by the Swiss Armed Forces. It is probably the most demanding mountain race in the world: more than 3'500 participants compete on foot and skis in a race in which they cover more than 8'000 meters in altitude. Besides Swiss military personnel and foreign troops, many civil teams compete in this athletic competition in the midst of the Valais Alps.
The PDG, however, is not only a major athletic challenge. For many years, the CS bde 41 has been building and operating a digital communications network in hard-to-reach terrain under extreme weather conditions at an altitude of 3'000 meters and above. We thereby connect temporary Swisscom mobile antennas using state-of-the-art line of sight technology. The athletes therefore are in contact with the race organization at all times during the race. The enciphered and highly redundant line of sight network simultaneously also provides telephone and computer connections for the military command.
In 2010, the PDG took place during the month of April. Representing the Command Support Brigade, parts of Line of Sight Battalion 16 were on duty.
