Three and EE throw weight behind London Underground 4G project

UK Operators Three and EE have teamed up with infrastructure firm BAI Communications to pipe in 4G and later 5G to commuters on the tube.
The deal is for 4G and ‘5G ready’ connectivity, and the two operators will work with BAI, which was awarded a 20 year concession by Transport for London to deliver mobile connectivity to the tube earlier this year.
Apparently all mobile operators will be able to access the London Underground wifi, as well as BAI’s neutral host mobile network
