Transport for London (TfL) is to roll out wireless broadband technology across the majority of the Underground network by June 2012, it has been reported.
Some 120 Tube stations will be equipped with Wi-Fi technology prior to the London Olympic Games next summer, enabling commuters to access the web on mobile devices such as tablet computers.
TfL said the decision to undertake the project came after last year's trial of Wi-Fi access at Charing Cross was "met with enthusiasm by passengers".
A tender process for the necessary infrastructure work has been opened and the successful bidder will be announced by the end of the year.
Mayor of London Boris Johnson said the delivery of Wi-Fi to station platforms and public areas "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 travelling.
"We are inviting companies to bid to do this before next June, which would mean that even Londoners going underground will be able to keep up to date with the British medal tally at the 2012 Olympic Games," he stated.
