Brighton is the next location to be tested for potential 4G interference on digital TV services by the at800 organisation as part of its ongoing pilots.
Around 80,000 locations will be involved in the tests, with all residents being sent information on the work being carried out and 2,424 premises being sent filters pre-emptively. At800 said it had seleted some households to receive filters first to see whether it's better to send out filters at first or wait for people to request them.
Brighton's TV signals are sent within a portion of the 700MHz range that sits very close to the 800MHz band while the geographic nature of Brighton makes it a good location to test issues, the organisation explained.
Simon Beresford-Wylie chief executive of at800 said: “The hilly terrain in Brighton – which can affect TV signals – coupled with Freeview being transmitted on frequencies very close to 4G at 800 MHz will make this a very useful trial. We urge viewers in Brighton to call us should they see any new problems with their Freeview reception.”
The tests will begin in mid-May and will be the latest in a series of pilots to examine the impact of 4G spectrum with similar tests taking place in London. These have seen 28,000 homes in the west of the city sent filters to mitigate against the potential effects of 4G signals. Similar tests are also taking place in Greenwich, south east London.
At present no 800MHz 4G services are live in the UK but they will be switched on later this summer when O2 and Vodafone both bring their services online in this spectrum range.
