You could be checking your email on the Underground by the London 2012 Games as Wi-Fi is rolled out to more stations.
Following the success of a Wi-Fi trial at Charing Cross station, London Underground (LU) has decided to make wireless internet access available at more stations across the network.
The first phase of the roll-out would see staff Wi-Fi connections made available to the public at 16 Tube stations, with up to 120 stations offering internet access by June 2012.
Boris Johnson, Mayor of London, said: "The roll out of Wi-Fi technology across the platforms and public areas of our Tube stations will finally allow Londoners to use mobile devices to pick up their emails, access social media sites and stay in touch with the world above while they traverse our subterranean transport network."
More than half of commuters would welcome wireless access at stations, according to research by Transport for London (TfL) following the Charing Cross trial, which was carried out with BT Openzone.
However, the LU Wi-Fi network would not extend to trains, explained TfL, meaning that users would only be able to go online at stations and not in tunnels.
TfL added that any hotspots would need to be funded by mobile operators like BT, O2 or T-Mobile for example, with no need to increase fares or create additional costs for tax payers.
