"TfL carries up to four million passengers a day on the London Underground network, and renewing and preparing the communications network for the future has long been regarded as essential to maintain and improve critical infrastructure. Before it carried out its first expansion work, TfL noted that legacy systems can slowly become unreliable and disrupt services, leading to delays and an overall negative impact on passenger journeys."
"All of the three mobile network operators - VodafoneThree, EE and Virgin Media O2 - are taking part in the roll-out, as part of the Mayor of London's and TfL's stated commitment to bring mobile connectivity to the whole of London's transport network. The expanding coverage will host the new Emergency Services Network (ESN) which, when fully operational, is designed to give first responders immediate access to life-saving data, images and information in live situations and emergencies on the frontline."
More stations and tunnelled sections of the London Underground now have 4G and 5G mobile coverage, with connectivity strongest up to 30m underground. TfL carries up to four million passengers daily and is renewing communications infrastructure to avoid legacy-system failures that can disrupt services and delay journeys. VodafoneThree, EE and Virgin Media O2 are participating in the roll-out. The expanding network will host the Emergency Services Network (ESN) to give first responders immediate access to data and images during incidents. Boldyn Networks holds a 20-year concession from June 2021 to deliver full coverage by around 2026 and to install a fibre backbone. Around 400 engineers work overnight on the project.
