A supplier for Wi-Fi across the London Underground network will be announced this spring, promises
Transport for London.
TfL says the Wi-Fi implementation across 120 underground stations will be completed in time for the 2012 Olympics.
The announcement of the chosen bidder had originally been scheduled for the end of 2011, but is now expected in early spring.
Gareth Powell, director of strategy and service development, said: "London Underground is continuing with preparations to install the necessary infrastructure and is on schedule to complete the project as planned."
Other data services and links to external sites may be subject to a subscription fee, and the supplier will manage all aspects of this service, including billing users. The contract is expected to last for five years, but could be extended.
Road warrios take note - although the Wi-Fi service will allow commuters to access the Internet underground in stations, Wi-Fi access will not be available on Tube trains themselves.
