UK Train Passengers Endure Unreliable Mobile Signal, Ofcom Report Reveals
Train passengers across Great Britain routinely experience unreliable mobile phone signal, rendering activities like social media use or video streaming unfeasible for most journeys. This finding comes from a recent report by Ofcom, the media regulator.
Network Performance Falls Short
The report details significant shortcomings across major mobile networks. Vodafone achieved Ofcom's 'good performance' benchmark—defined as a minimum download speed of five megabits per second, an upload speed of 1.5 megabits per second, and a 50-millisecond response time—in only 17% of tests. EE, despite being the strongest performer, managed to meet these standards just 42% of the time. Three and O2 fared even worse, with compliance rates of 21% and 20% respectively. Ofcom noted that these thresholds are considerably lower than average 4G speeds, yet networks still largely failed to attain them.
Beyond mobile signal, onboard Wi-Fi services performed poorly, meeting good performance standards in only 1% of instances. This was attributed to outdated technology and excessive throttling of internet speeds by train operators.
Infrastructure and Investment Demands
Mobile UK, representing major providers including EE, Virgin Media O2, and Vodafone, pointed to 'unique structural and capacity challenges' inherent in maintaining robust train signal. The organisation urged government intervention, calling for immediate planning reform and investment. It also suggested that taxpayers should contribute to funding the necessary infrastructure to eliminate 'black spots' on the rail network, asserting that 'commercial rollout alone cannot bridge the gap'.
Ofcom corroborated these challenges, identifying weak signals from phone masts near train lines and issues with signal penetration through certain carriage types as primary culprits. The regulator also criticised local authorities, noting that some had rejected over 90% of applications for new or upgraded mobile infrastructure within the last five years. Ofcom has called on both mobile networks and local authorities to 'step up' efforts to provide more reliable services. The Department for Transport has plans to invest £57 million in boosting train Wi-Fi, intending to enable connections to low-earth satellites, a departure from reliance solely on 4G and 5G networks. Transport Secretary Heidi Alexander is expected to formally announce these plans this summer.
