As with any enterprise, the Organizing Committee and everyone involved with it relied heavily on technology in order to deliver a successful event. ATHOC maintained two separate data networks, one for the preparation of the Games (known as the Administrative network) and one for the Games themselves (Games Network). The technical infrastructure involved more than 11,000 computers, over 600 servers, 2,000 printers, 23,000 fixed-line telephone devices, 9,000 mobile phones, 12,000 TETRA devices, 16,000 TV and video devices and 17 Video Walls interconnected by more than 6,000 kilometers of cabling (both optical fiber and twisted pair).
