London mobile data speeds lag behind global cities
HNL visual fileLondon

Mobile network performance in London has fallen short of national and international benchmarks, according to research commissioned by City Hall. Tests conducted in nine inner London boroughs found that every location experienced network response times exceeding the regulator Ofcom's target of 50 milliseconds.

Eversholt Street in Somers Town, Camden, and Dalston in Hackney were identified as the areas with the slowest mobile data performance. These locations, along with Chapel Market in Islington, Brick Lane in Tower Hamlets, and the vicinity of Kings Cross Boulevard and Coal Drops Yard in Camden, failed to meet multiple performance criteria, including download speeds, upload speeds, response times, and signal strength.

Capacity Versus Demand

The research concluded that the demand for mobile data in London is currently outstripping the capacity of existing networks. This issue is compounded by the planning process, with Mobile UK reporting that London approves fewer than 40% of mast applications, a significantly lower rate compared to over 80% in cities like Greater Manchester, Leeds, and Edinburgh. The capital's dense urban environment and planning restrictions, including those related to conservation areas and listed buildings, further complicate the deployment of new infrastructure.

City Hall forecasts that demand for mobile data in London will increase fourteenfold over the next decade. Current network plans are not expected to keep pace with this projected growth, necessitating improvements in infrastructure and planning processes.

Recommendations for Improvement

To address these challenges, the report recommends that local councils appoint a dedicated mobile connectivity lead. It also advises councils to actively identify potential sites for new equipment, review previously rejected mast applications, and consider signal coverage requirements when approving new developments. City Hall has pledged to publish borough-level data, provide support to councils, and facilitate discussions between networks and local authorities.

The report noted that the difference in performance compared to leading global cities lies more in network organisation and connectivity rather than the sheer number of masts. International comparisons placed London 17th out of 19 cities for download speeds and last for upload speeds.

The proposed measures are voluntary and do not include additional funding, with all ten recommendations falling to the councils, despite mobile networks being responsible for investing in and operating their infrastructure.
