In 2021, Boldyn Networks Limited was awarded a 20-year contract by Transport for London (TfL) to deploy a 5G-ready mobile network across the entire London Underground system. The project involves Boldyn investing approximately £1 billion ($1.35 billion) to install fiber optic cables, leaky feeders, and high-power radios in 121 underground stations. The UK's three major mobile networks—EE, Virgin Media O2, and VodafoneThree—will share the infrastructure to provide customer connectivity.
