In a press release, Transport for London (TfL) said the capital's Oxford Circus, Tottenham Court Road and Bank stations would be among the first fully connected stations by the end of the year, followed by Tottenham Court Road, Euston, and Camden Town by the end of 2022.
Mobile reception was introduced on the eastern half of the Jubilee line in March last year. TfL says the additional infrastructure will support 5G as well as 4G, but that it will be the responsibility of mobile operators to offer support for the fastest network speeds.
TfL is partnering with BAI Communications (BAI), a global provider of 4G and 5G connected infrastructure, to plug so-called coverage "not-spots" in the underground network. The over 1,242 miles of fibre cabling installed in London Underground tunnels will also benefit above-ground coverage for buildings and other infrastructure by allowing more mobile transmitters to be installed.
