Summary:

People traveling through the tunnel from the UK to France will from March be able to get 2G and 3G coverage. The carriers say they will offer 4G services down there, too.

The British carriers EE and Vodafone have signed a 10-year agreement with the operators of the Channel Tunnel, the 50-kilometer (31-mile) underwater tunnel that links the UK with France, to provide mobile services there.

The deal with Eurotunnel covers the North Running Tunnel, going from the UK to France. French carriers Bouygues Telecom, Orange and SFR struck a similar arrangement covering the South Running Tunnel in 2012, just before the London Olympics.

Echoing that deal, EE and Vodafone said that from March this year they will offer 2G and 3G services to passengers of both high-speed Eurostar passenger trains and Le Shuttle, the rail-bound shuttle service for cars. Both companies said they also intended to offer 4G services in future.

The carriers said they had managed to install the necessary equipment without any disruption to rail traffic, and the quality of calls 100 meters (328 feet) underwater would be as good as above ground. According to an EE spokesman, data speeds will reach 3-5Mbps on 3G and around 12-15Mbps on 4G.

The technology provider is Axell Wireless, with its distributed antenna system (DAS). Similar to the South Running Tunnel deployment, the key here is “leaky feeder” technology, i.e. a long cable acting as an antenna with the assistance of repeaters, hooked up via radio-over-fiber to the carriers’ base stations.

  1. The north-running tunnel would go from France to the UK, not the other way around. The UK is north of France.

    1. You are correct about the UK being north of France, but the UK-France stretch of track is still called the North-Running Tunnel. I’m not quite sure why that is.

      1. Thanks – but what I meant to point out is the misplaced dash. It’s the “north running tunnel”, not the “north-running tunnel”. The tunnel doesn’t run north, of the two running tunnels (as opposed to maintenance tunnels) it’s the north one.

        1. Ah right – fixing that now. Thanks.

  2. Reblogged this on The LTE World Series Blog and commented:
    This is good news and I especially like that it uses, ““leaky feeder” technology – because that sounds amusing.

    I would like to know if using EE in the tunnel will count as roaming when coming from the UK? Last summer I purchased a 50Mb data roaming bundle and though it took some effort and some careful monitoring if lasted me for my four day trip. 4G speeds would certainly have been appreciated at time. Note: 3G at Disneyland Paris is slow…
