BT has installed 500,000 (HALF A MILLION) WiFi access points in London and the Olympic Park in Stratford to cope with the number's of users on site. When spectators are leaving one game and the next set arriving there can be up to 300,000 people on the site and that's a hard peak to cope with. Operators (Everything Everywhere, O2 and Vodafone) are offering their customers free access to around 4,000 of the WiFi access points to off-load the mobile networks which will be creaking under the loads. BT has installed around 3,000 miles of fibre and the network is carrying about 60GB/s (i.e. around 480Gb/s). BT has installed around four times the capacity that was available at the Beijing games.
