London Tube closes the 5G gap with streets above
Mobile signal below ground beats the citywide average, Ookla says
Mobile coverage on parts of London's Underground now rivals the streets above for 5G availability and signal strength, according to analysis by network intelligence biz Ookla.
Cellular support has been rolling out across the Tube since Mayor Sadiq Khan promised in 2021 to connect all stations and tunnels by the end of 2024.
