This was the Patrouille des Glaciers 2018 - Network construction under extreme conditions


Patrouille des Glaciers 2018

Swisscom material on Tête Blanche, at the highest point of the PdG

 

It's hardly surprising that the Patrouille des Glaciers is known as the world’s toughest ski tour race. The 4500 participants spend months preparing for it and need enormous stamina and discipline. This also applies to everyone else who takes part, especially the employees of Swisscom, which had to set up its own temporary 2G and 4G networks in the most unappealing high Alpine conditions at 3000 metres about sea level, networks for both its company radio and, as a complete novelty, a network for the Alpine Internet of Things. In all, more than three tonnes of equipment – base stations, antennas, repeaters and other telecom equipment – was transported up into the mountains.




The LPN (Low Power Network) is a dedicated network for the Internet of Things and combines a tremendous reach, energy-saving transmission and a comparatively easy network setup. It now covers 95% of the population. The LPN enabled patrols to be followed seamlessly using what are known as trackers, for safety reasons and for live tracking on both the Web and the app.

The tracking data was updated every two minutes during the race. The interactive map was constantly evolved to provide an overview of the patrols in the field.
