Train passengers can now use 4g in the approximately 50 km long channel Tunnel. This is made possible by the upgrade of the 3g network, with 4g equipment. Tunnelexploitant Eurotunnel is working jointly with four providers.
Eurotunnel has the 4g equipment made compatible with the 4g networks from EE, O2, Vodafone and Bouygues Telecom. Therefore, the parties have a ten-year agreement. According to the tunnelexploitant can passengers between France and the United Kingdom, with speeds of up to 140km/h through the tunnel, now with a, on average, ten times higher speed internet compared to the old 3g network that the tunnel was built. Annual travel approximately 21 million passengers by the undersea tunnel.
According to Eurotunnel, the creation of the necessary hardware in the channel Tunnel for almost three years to learn. One of the challenges that Alcatel-Lucent met with the installation of 4g equipment was the separation of gsm-p-movement, which is intended for normal telephone calls, and specifically for the railways developed gsm-r standard.
