"User demand has moved on. Expectations of technology are higher than at previous Olympics. Now 50 per cent of mobile phones sold are smartphones. As a result and that carries the expectation that all the information from the Olympics will be in the palms of users' hands in real time."

In expectation that this Smartphone demand will be extremely high at the actual Olympic Park in Newham, London Locog has created a very large wi-fi zone around the park.

"I won't guarantee it will be perfect, but it will be just fine," Pennell says with studied conservatism.

A quarter of the Locog budget has been attributed to technology. Pennell's team has put technology into over 100 competition venues, not only in London but also in football stadiums in cities such as Coventry, sailing venues in Weymouth and cycling venues in Surrey and Essex.

The technology landscape includes a broadcast centre, the Olympic village, a central control centre, transport depots serving the park, Heathrow Airport, temporary venues like the All England Club Wimbledon, Earls Court Exhibition Centre and some of the training venues.
