London Underground to get network-wide mobile coverage

The Mayor of London is honouring his election manifesto by introducing Wi-Fi across the Underground network by 2024.

Honouring a manifesto commitment, Mayor of London Sadiq Khan has announced that passengers on London Underground will soon have full mobile connectivity and internet access within every station and tunnel.

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

Uninterrupted 4G mobile coverage has already been introduced on the eastern half of the Jubilee line. Now the new concession will see a backbone of mobile and digital connectivity 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. 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.  The new high-capacity fibre network will bring fibre directly into London’s neighbourhoods, creating new opportunities to serve homes and businesses with gigabit-capable speeds and supporting digital inclusion.

Digital connectivity will extend to all Underground stations, trains and tunnels.

BAI, which was awarded the concession after a competitive tender process, is a leading global provider of 4G and 5G connected infrastructure. The agreement will build on BAI’s significant experience of deploying communications networks in highly dense urban environments across the world, including New York, Toronto and Hong Kong.

The neutral-host network being delivered to London as part of this concession will be the most advanced network of its kind in the world and available for use by all mobile operators. The infrastructure will also be 5G ready, allowing for a seamless upgrade for mobile operators in the future.

The London Underground network is one of the world’s largest underground networks and, prior to the pandemic, was used by more than five million passengers a day. 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 has already begun installing the necessary cabling within a number of 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.

Sadiq Khan. Mayor of London.

Sadiq Khan said: “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.

“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.”

Shashi Verma, TfL.

Shashi Verma, Chief Technology Officer at TfL, said: “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.

“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.”

Since March 2020, TfL has been running a pilot of mobile connectivity on the eastern half of the Jubilee line covering station platforms and tunnels between Westminster and Canning Town. The pilot section will now be adopted by BAI, which will work to upgrade any assets to its proposed network-wide design.

The network will also help to create a smarter, safer London. It will host the Home Office’s new Emergency Services Network, which will replace the existing Airwave system currently used by the Police, Fire Services and emergency response teams across Great Britain. TfL has ensured that the latest requirements for the Emergency Services Network are fully incorporated and addressed within the network design.
