"Our temporary event network is for the wrestling federations and for all partners," explains Lochbrunner. In addition to the various sponsors, these also include the catering businesses and Swiss television. Nowadays, without an internet connection, neither a cash register system nor the transmission of video signals, audio and lighting technology or the logistics supply for fan articles and drinks can run. The SRF, the various LED walls on the site, the public viewing on Barfüsserplatz in Basel or the surveillance cameras were all also dependent on interference-free transmission. "In Swisscom's central control room, we collect all the video signals and then distribute them. If the fibre optic network is the spinal cord, then our central control room is the brain of this system."
