New high-speed 4G LTE broadband is ready for testing, with Everything Everywhere and BT looking for volunteers in Cornwall to give it a workout.Why Cornwall? Essentially, it's an attempt to utilise the technology to provide mobile broadband in 'expensive-to-reach' rural areas. With that in mind, the trial will run from September to December in South Newquay. Don't get too excited though. The rest of us will have to wait until 2014 before we can use the dongles and 4G-friendly mobile devices that will follow.Everything Everywhere and BT will share their fixed telecommunications and mobile technology to provide high-speed wireless broadband in the area, with up to 100 mobile and 100 fixed line customers trying it out, in the hope it will solve the problem of a lack of fixed broadband coverage. Or indeed, very slow speeds from traditional broadband. Everything Everywhere will also look to test 4G-enabled mobile handsets and broadband dongles as part of the trial.Tom Alexander, CEO of Everything Everywhere said: 'Our ambition is to have the best 4G network and be pioneers in enabling Britain’s superfast wireless future. We strongly believe that, by sharing our network and mobile assets in this way, we can make a valuable contribution to the economics of rural broadband services. Our work with BT is providing a test bed for new technologies such as 4G LTE which, with the correct allocation of sub 1GHz spectrum from the Government, has the potential to make a real impact on the way in which we communicate in the future. The Government has previously stated its desire for the UK to have the best in class superfast broadband network in Europe by 2015, and we hope to help this vision become a reality.'Residents who wish to participate in the trial can register their interest here. The trial will be free of charge to all triallists, which is a very tasty bonus.
