A report from the UK communications regulator, Ofcom, has highlighted severe deficiencies in mobile network coverage for train passengers across England, Scotland, and Wales. The findings indicate that up to 83% of performance tests fell short of the ‘good performance’ threshold, prompting calls for a nationwide improvement initiative.
Disappointing Test Results
The Ofcom study assessed mobile signal strength across 24 rail segments, revealing that even the top-performing network, EE, achieved the ‘Good Performance’ standard less than half the time. Other networks, including Three, O2, and Vodafone, managed to meet this benchmark in only 17% to 21% of journeys. ‘Good Performance’ is defined as a download speed of at least 5 Mbit/s, an upload speed of at least 1.5 Mbit/s, and a latency of 50 milliseconds or better.
Wi-Fi Connectivity Lags Behind
On-board Wi-Fi services were also scrutinized, with Ofcom reporting that connectivity performed adequately just 1% of the time. The study noted that throttling by train operators, with caps around 1 Mbit/s, severely limited the quality of service. The technology used for Wi-Fi often relied on older standards, such as Wi-Fi 4 or 5, which do not meet modern passenger expectations.
Challenges in Connectivity
The report attributes the poor mobile performance to weak signal strength along rail corridors, exacerbated by certain train carriage types. Passengers in rural and intercity areas experience worse service compared to those in urban locations, where cell base stations are more prevalent. Latency issues were identified as a primary reason for failing to meet performance standards, even when speed metrics were adequate.
Call for Collaborative Solutions
Ofcom emphasizes the need for a coordinated effort among mobile operators, train companies, and regulatory bodies to enhance connectivity on trains. Kester Mann, director at CCS Insight, remarked on the complexities of providing reliable mobile connectivity at high speeds and through challenging environments like tunnels. Ofcom is currently seeking feedback on these issues until July 29, underscoring the urgency for improvements in train connectivity.
