From TfL» (Transport for London - about):

Quote
4G on Jubilee line tunnel section from March 2020
19 July 2019
4G phone signal will allow customers - for the first time - to check emails, plan meeting up with friends and keep in contact while traveling through the tunnels or on Jubilee line platforms in east London
  •     Hundreds of miles of cabling now installed across the network and TfL is in discussion with mobile network operators to ensure their customers can benefit when the first section goes live
  •     Next stage of procurement for concessionaire to make 4G services available across the rest of the network will commence shortly, allowing the whole of the London Underground network to have mobile connectivity by the mid-2020s
  •     Introduction key part of mayoral ambition to improve digital connectivity at home, in our high streets, public spaces, stations and now right across the transport network

The eastern half of the Jubilee line will get full mobile connectivity within station platforms and tunnels for the first time from March 2020 - helping to remove one of the most high-profile mobile 'not-spots' in the UK (United Kingdom) - Transport for London (TfL) confirmed today.

The trial section, which will cover the platforms and tunnels between Westminster and Canning Town, will allow customers to check for the latest travel information, catch up on social media and read their emails or the latest news uninterrupted as part of their journey. It will build on the existing free WiFi service that TfL offers both within more than 260 WiFi-enabled London Underground stations and on TfL Rail services. The service will also cover ticket halls and corridors within stations along this section of the Jubilee line, with the exception of London Bridge and Waterloo stations which, subject to final approvals, will be added later during 2020.

TfL has been working to bring mobile connectivity to the below ground sections of London Underground, as part of a range of measures announced by the Mayor Sadiq Khan to boost digital connectivity across the capital and tackle London's areas of poor connectivity.

The trialling of 2G, 3G and 4G mobile services along this section of the London Underground network will allow TfL and the mobile operators to gain valuable experience of delivering mobile services on the Underground ahead of awarding a concession to deliver mobile coverage across the whole Underground network. The next stage of procurement for the concessionaire will begin shortly, with a look to award the contract by Summer 2020.

By installing cabling within tunnels and stations in advance of awarding the concession, TfL can better manage station access, reduce the amount of disruption these works may cause to customers and allow the concessionaire to then quickly utilise infrastructure once the final contract is awarded. TfL has also begun discussions with mobile network operators to ensure they can access the infrastructure for the pilot so their customers can benefit when the technology goes live.

I'm not sure quite how complete a radio system is being installed for this concessionaire to operate, and what the interface with the MNOs will be:
Quote
Jasmine Whitbread, CEO (Chief Executive Officer) of London First, said:

'This is a welcome step on the journey to delivering widespread internet connectivity on London's tube network - enabling people to stay in touch on public transport will boost the capital's productivity.

'We look forward to the transformative impact that further projects to improve digital infrastructure on the London Underground will have for the capital, including the programme to deliver better, more real-time customer information throughout the Tube network.'

Delivering mobile connectivity within the London Underground network, which is one of the world's largest underground networks and used by more than five million passengers a day, is extremely challenging. Once fully delivered, more than 2,000 kilometres of cabling are expected to have been installed within tunnels and stations, all of which will need to be fitted outside of operational hours. With the Night Tube around the clock on Fridays and Saturdays, this limits the number of hours engineers can work on the project a week. The space between the trains and the tunnel walls is also often narrow, with little room to safely install equipment, meaning that any work need to be carefully planned and carried out to avoid potential disruption.

Following the launch of the formal procurement process last summer, TfL has now shortlisted four bidders who will be invited to tender for the concession, the next stage of which will begin shortly. Over the last few months, TfL has been working with the shortlisted bidders to help them understand the complexities of working within a transport network which first opened more than 150 years ago, as well as to ensure the tender documentation correctly reflects the latest opportunities for providing better connectivity on our network.

The system will also 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 Britain. By aligning the projects, TfL has ensured that the latest requirements for the Emergency Services Network are fully incorporated, reducing the need for additional contracts or amendments in the future.

What is London First? I'm not sure; it seems to be a kind of chamber of commerce - but what is its role in this project?

Note that this is the new, larger, relatively straight Jubilee Line Extension - I gather it's very unlikely this will be expanded to the older parts of the Deep Tube as the curves and extremely limited clearances make it impractical.

I have also seen references that this is a pilot and it will be extended to the whole network.  There is specific reference to working in narrow tunnels from London First.  London First also point out that this will be a requirement for the much delayed emergency services network.

I hope but won't hold my breath that this is limited to data and that voice calls will be blocked whether they be through the network provider or apps such as WhatsApp. The tube is noisy enough as it is without some noisy ***** shouting into their phone.

Last year there was an announcement that a concession would be let for the full system after a competitive tender, and today that contract was announced. This is the TfL» (Transport for London - about) press release minus the quotes:
Quote
Mayor fulfils commitment and confirms high-speed mobile coverage across Tube network
22 June 2021

High speed mobile coverage will be delivered across London Underground alongside a new full-fibre network to provide London's homes and businesses with faster internet and better connectivity


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 today announced.

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 (United Kingdom).

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.

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.

BAI, who 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 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.

Five million passengers a day

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.

In open sections phones dropped from platforms was one of the biggest reasons for passengers jumping down on to the track to retrieve them or asking staff to do the same.

Unintended consequence.
