c2c Maps Mobile Coverage Along the Essex-Thameside Railway

  • c2c have collaborated with mobile analysts Streetwave to map mobile coverage experience across the Essex Thameside Railway
  • Coverage experience was mapped across the route during both Peak and Off-Peak travel times
  • EE had the highest levels of coverage along the line during both Peak and Off-Peak Hours

Newport, 19 March 2024: Streetwave have published the latest findings from a pioneering mobile coverage survey performed along the Essex Thameside railway line for c2c to analyse passenger experience of the mobile networks as part of plans to improve the Wi-Fi provision for customers.

Understanding mobile coverage is important for train companies as it allows them to identify which mobile networks can deliver the most dependable train Wi-Fi solutions.

Coverage  was analysed for the four main mobile networks in the UK: EE, O2, Three and Vodafone.

3 surveys were carried out to compare a passenger’s experience of the mobile networks between Peak and Off-Peak times. The surveys took place between 30th January 2024 and the 2nd February 2024.

This was done to benchmark the extent to which mobile coverage experience worsened during commuting hours when larger passenger numbers increase mobile network congestion.
