4G mobile broadband services have been made available in the Channel Tunnel for the first time.
Passengers travelling from the UK to France - and vice-versa - will now be able to access super-fast mobile services on their laptops, tablets and smartphones.
This is after Eurotunnel worked with EE, O2, Vodafone UK and Bouygues Telecom to create a comprehensive 4G network 100 metres below the sea.
Download speeds will be around ten times as fast as those previously available via 3G connections.
Eurotunnel Chief Operating Officer Michel Boudoussier said the new service means passengers will have access to "incredible connectivity" and "astonishing access to mobile services".
He claimed they will be able to access better information, allowing them to "remain operational" during their train trip.
Other customers will have the opportunity to relax in the Channel Tunnel courtesy of 4G internet access, Mr Boudoussier added.
EE became the first broadband operator to launch 4G services under the English Channel on September 24th.
Between mid-September and mid-November, 25,000 EE customers used the network to access super-fast mobile broadband.
EE revealed that peak 4G download speeds of 57 Mb were delivered during the first two months of the service, with the average speed being 13.5Mb.
Fotis Karonis, EE's Chief Technology Officer, claimed that his company's 4G rollout "has changed the mobile landscape in the UK".
"We’re very proud to have been the first UK operator to put superfast data underground in the Channel Tunnel," he stated.
Mr Karonis added that EE has delivered a "great experience" to many thousands of customers, and made a real difference to people commuting and going on holiday.
