After a bit more detective work we discovered that the roadworks database listed the responsible party as Cityfibre, although Arqiva seemed to be the contractor. CityFibre and Arqiva are partnering on what they claim is the UK ’s largest pilot of wholesale , 5G - ready small - cell infrastructure . The 15 km high - density fibre network in North London 's Hammersmith and Fulham borough is BT ’s first venture in the UK market . It will be multi - operator capable and provide the bandwidth for mobile network operators . Arqiva was awarded a pilot contract by local authorities in 2014 allowing it to use lampposts and other street assets as pieces of infrastructure critical to network densification .
