The rollout is currently under bid by Chinese telecoms manufacturer Huawei, which would allow hundreds of thousands of Londoners and tourists each day to work while commuting to work.
Mobile access has been difficult, if not impossible on the vast majority of the network in central London. Only certain mainline railway stations and Underground stations are equipped with Wi-Fi and cell repeaters, such as Charing Cross and St. Pancras.
But mobile network access on the Tube has gone without controversy.
After the Kings Cross fire in 1987, an inquiry headed by Desmond Fennel QC led to recommendations in radio communications on the Underground. Though nearly twenty years after the disaster, now police and emergency service radios now work underground.
Conversely, some are concerned that the ability to communicate through cell networks on the Underground could assist bombers who could remotely detonate explosives on trains, as seen in 2005.
As a frequent commuter on the Underground, along with hundreds of thousands of students who study at over a hundred universities in London, the benefits would outweigh the perceived negatives.
Similarly during the time I spent in New York City last year, I recall looking at my BlackBerry, clear as day as I sat next to Mary Jo Foley on the subway traveling south towards towards Wall Street. I turned to her and said, "Ooh, I can get mobile signal" in a moment of delight.
Perhaps we weren't that deep underground after all. Nevertheless, I saw this as New York taking care of its telecommuters. How wrong I was.
Considering what the Tube is like first thing in the morning, it should probably come as no surprise that the most popular reason for wanting mobile signal on the Underground was to "let people know when I'm running late", according to recent research.
