Mobile broadband could become a reality on the London Underground, with Chinese telecoms giant Huawei standing by to carry out infrastructure work.
According to the Sunday Times, the company has offered to install mobile transmitters on the Tube for free, as a gift ahead of the London 2012 Olympic Games.
Creating a mobile phone network underground - which could support voice and broadband services - could cost £50 million, the news provider stated.
Internet service providers O2 and Vodafone are said to be willing to fund installation work, while Huawei would generate an income through maintenance.
A Transport for London (TfL) spokesperson stated: "Transport for London and the Mayor of London are currently in discussion with mobile phone operators and other suppliers about the potential provision of mobile phone services on the deep Tube network.
"Given the financial pressures on TfL's budgets, any solution would need to be funded through mobile operators with no cost to fare or taxpayers. Discussions are ongoing."
China staged the most recent Olympic Games in Beijing in 2008.
