Wi-Fi access for London underground

Almost half of London's underground stations are to be outfitted with Wi-Fi access in preperation for the hosting of the 2012 Olympic Games.
Bids are being invited by Telecom companies to provide Wi-Fi for 120 stations by June 2012.
A six month test in October 2010 was deemed a success after London Mayor, Boris Johnson, promised that “every lamp post [and] every bus stop will one day very soon, and before the 2012 Olympics, be Wi-Fi enabled” as part of an effort by to position London as a world leader in technological innovation.
Users will only be able to connect to the Wi-Fi on the platforms, not the trains themselves.
