Tube bosses have announced plans to roll out wi-fi networks at 120 stations across the capital before the start of the 2012 Olympic games. Following a successful trial at Charing Cross station, passengers will be able to log on to the internet on laptops and mobile devices in public areas and on platforms at tube stations, although the network will not allow access on trains. London’s tube service won best metro in the world at the annual Metro Awards. It is thought that a contract will be awarded by the end of 2011 to have the system in place by the start of the games, with the cost borne by service providers.
