Londoners will be able to enjoy mobile coverage on the city’s Tube network by the end of 2024, but some of the city’s stations will see work begin very soon.

Customers on London Underground will be able to access full mobile connectivity and internet access within every station and tunnel, the Mayor of London has announced.

Transport for London (TfL) has awarded a 20-year concession to BAI Communications (BAI) which will enable mobile coverage on the whole Tube network, helping to remove one of the most high-profile mobile ‘not-spots’ in the UK.

The concession will see a backbone of mobile and digital connectivity established across London.  Uninterrupted 4G mobile coverage has already been introduced on the eastern half of the Jubilee line and will be expanded in phases to ticket halls, platforms and tunnels on the Tube network over the next three years, with all stations and tunnels due to have mobile coverage by the end of 2024. This will allow customers to check the latest travel information, keep on top of their emails and the latest news, catch up on social media, watch videos or make calls throughout their journeys.

London’s Tube tunnels will also be used to provide full fibre connectivity across the city, which can then be connected to buildings and street assets like street lighting and bus stops. TfL hopes this will help to further increase mobile coverage through small mobile transmitters, as well as leveraging the power of 5G to deliver city-wide improvements and future growth. 

Once fully delivered, more than 2,000 kilometres of cabling are expected to be installed within tunnels and stations, all of which will be fitted outside of operational hours. In addition to benefiting customers, providing 4G on the network will generate additional revenue for TfL across the 20-year length of the concession, as well as helping operational teams by providing better connectivity while underground.

To help reduce future disruption, TfL says it has already begun installing the necessary cabling within a number of London Underground stations and tunnels to help reduce the need for additional closures and ensure mobile connectivity can be introduced more easily. This includes cabling already installed on the Jubilee and Victoria lines, as well as within the Northern Line Extension. Work will now begin to prepare some of London’s busiest stations for mobile connectivity, including Oxford Circus, Tottenham Court Road, Bank, Euston and Camden Town, ahead of them being some of the first to be connected by the end of 2022.

“I promised Londoners that if they re-elected me for a second term as Mayor I would deliver 4G throughout the Tube network. It’s already up and running on the eastern half of the Jubilee line and I’m delighted to announced today that I am fulfilling that commitment and full internet access will be available across the Tube, with key central London stations such as Oxford Circus and Euston set to benefit before the end of next year,” said Mayor of London, Sadiq Khan.

“Protecting jobs and stimulating our city’s economy is a top priority for me as London rebuilds after this pandemic, and investing in London’s connectivity and digital infrastructure is central to this.”

“London Underground was born in the 19th century, and this concession to deliver mobile coverage to the whole Tube network ensures it continues to adapt for customers in the 21st century,” added Shashi Verma, Chief Technology Officer at TfL.

“Providing mobile connectivity to customers within the tunnels and on platforms across London will help them stay connected more easily, and will both provide a long-term revenue stream for TfL and support economic growth across the city.”
