The long-awaited 4G network rollout on the Elizabeth Line’s underground sections is now complete, signalling a step forward in connectivity for Londoners.
- Transport for London (TfL) has lagged behind other European capitals in providing underground mobile coverage.
- Despite advancements, much of London’s underground remains disconnected from mobile networks, contrasted with Paris and Lisbon’s early adoption.
- The project aims to enhance staff communication and emergency response capabilities with the new Emergency Services Network (ESN).
- Efforts continue to expand this coverage across more of London’s transport network, improving passenger experience.
The 4G network has been successfully implemented across the underground sections of the Elizabeth Line, marking a significant milestone for Transport for London (TfL). This achievement represents a crucial development in enhancing mobile coverage in the capital’s transport network. However, London still falls short compared to other European cities, where comprehensive mobile connectivity has been a standard for years. Notably, Paris and Lisbon completed their metro 4G coverage in 2020 and 2018, respectively.
While London initially led with technologies such as contactless payments, its progress in mobile network implementation remains slow. TfL’s initiative is expected to offer improved communication channels for its staff, contributing to safer and more reliable operations. The establishment of the Emergency Services Network (ESN) promises real-time data access for first responders, which is vital for handling emergencies effectively.
Coverage extension efforts are ongoing, with work in progress along the Northern Line towards Morden and between King’s Cross St Pancras and Moorgate. Plans are also underway to extend coverage on the Bakerloo Line between Piccadilly Circus and Embankment, along with the Piccadilly and Victoria Lines in the coming months.
TfL awarded Boldyn Networks a 20-year concession in June 2021 to deliver comprehensive high-speed mobile connectivity across the London Underground network. Boldyn is tasked with installing 2,000 kilometres of cabling and thousands of radios throughout tunnels and stations, a complex engineering feat that takes place outside operational hours to mitigate service disruption.
London’s journey to full underground mobile coverage continues, promising improved connectivity across its transport system.
