However, BT, the main telecommunications firm for the Games, have tried to ease the fears of event organizers, saying plans are in place to cope with an unprecedented number of people using mobile devices. To achieve this, BT has had to create the UK's largest single Wi-Fi installation.
Speaking to the BBC, BT's Stuart Newstead explained: "At peak time when one set of spectators leaves and another arrives you will have between 200,000 to 300,000 people on site.
"It's as well prepared as it can be. The key to the planning has been co-operation between the operators to maximise the laws of physics, allowing a far denser configuration of masts and antennas than normal to ensure as much capacity as possible."
Consequently, London 2012 organisers remain confident that everyone will be able to perform everyday tasks using their handheld devices, such as making calls and sending text messages, throughout the Games. In preparation for the event, BT has installed around 1,000 Wi-Fi hotspots.
