Connected London is the Greater London Authority's initiative to accelerate digital connectivity across the capital, encompassing the rollout of 5G networks, the expansion of full-fibre broadband, and the deployment of public Wi-Fi in high-traffic areas. The programme recognises that world-class digital infrastructure is the essential foundation upon which all other smart city applications — from IoT sensor networks and autonomous vehicle testing to remote healthcare and real-time transport management — depend.
A central innovation of the programme is its creative use of London's existing physical infrastructure for small cell deployment. Street furniture, traffic signals, bus shelters, and public buildings are being equipped with compact 5G antennas, avoiding the need for unsightly new mast installations and accelerating rollout across the city's dense urban fabric. This approach also reduces costs and planning obstacles, enabling faster coverage of areas where connectivity demand is highest.
The programme works closely with telecommunications operators, technology companies, and London's 33 borough councils to coordinate infrastructure investment and ensure that connectivity improvements reach all parts of the capital, including traditionally underserved areas. Digital inclusion is a core principle, with targeted efforts to extend broadband access to social housing estates, community centres, and public libraries.
Connected London's infrastructure supports a thriving technology sector employing over 600,000 people and underpins innovations ranging from real-time traffic management and environmental monitoring to telemedicine and remote education. Dedicated testbeds for autonomous vehicles, drones, and advanced IoT applications provide a controlled environment for companies to validate new technologies before wider deployment.
By treating digital connectivity as essential public infrastructure — on a par with roads, water, and electricity — Connected London ensures that the capital has the communications backbone needed to remain competitive, innovative, and inclusive in an increasingly digital urban economy.
