After a successful trial on the Waterloo and City line in the summer, Transport for London have confirmed they are planning to install 4G mobile coverage on the whole underground system from 2019.
London's Chief Digital Officer, Theo Blackwell, said: "This is a brilliant initiative and part of our work to improve connectivity at home, in our high streets, public spaces and across the transport network. TfL's innovation shows we can make a real difference and benefit Londoners through using city-wide public assets in a smarter way, starting with the Tube."
Whilst Graeme Craig, Director of Commercial Development at TfL, added: "The success of this trial shows that we are on track to unlock one of the UK's most high profile not-spots and deliver 4G mobile coverage throughout our tunnels and Tube stations. This is great news for our customers and will also help us generate vital commercial income to reinvest in modernising and improving transport in London."
Transport for London will now dedicate the first part of next year to tendering for a service provider.
Ker Anderson, Vodafone UK's Head of the London mobile network, shared: "We are delighted to have worked with Transport for London on this trial. Delivering 4G on the Tube will keep our customers connected while they are on the move. We have seen usage of mobile data traffic increase by around 300 per cent in London alone over two years.
"As a consequence, we continue to invest heavily in our network to offer Londoners, commuters and visitors with the strongest signal possible across the Capital, whether it's on the Waterloo & City line, the top of the Shard, Wembley Stadium, Trafalgar Square or Clapham Junction."
