4G testing heads to Brighton as at800 expands probe into Freeview TV inteference

Telecoms overlord the at800 Group is expanding its 4G trials to Brighton, announcing that a new round of Freeview interference testing will commence in the vibrant south coast city from mid-May.

Some 80,000 addresses in Brighton are being informed that a 4G mast will be activated in their area, with more than 2,400 households set to receive an at800 filter ahead of the switch-on.

The group said that Brighton was the next key battleground for TV interference testing, as the city's Freeview signal is transmitted on frequencies that are "particularly close" to the 800MHz frequencies used by 4G mobile broadband services.

"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," commented Simon Beresford-Wylie, chief executive of at800.

The Brighton trial is also significant for marking the first time at800 will specifically target elderly and disabled residents with a support service.

Viewers receiving a filter will need to fit it to their television setup between the aerial cable and TV or Freeview box. Those with an existing signal booster will need to connect it between the antenna and amplifier, with vulnerable residents set to enjoy a free installation service as part of the Brighton trial.

Anyone notified of the trial who subsequently experiences a problem with their TV signal is advised to contact at800 on 0333 31 31 800.

The Brighton trial follows initial Freeview interference testing in the West Midlands and further 4G investigations in London. Fears of an impending 4G apocalypse derive from the close proximity of the 800MHz LTE frequency to the UK's Freeview signal.

The at800 Group is a joint venture set up by 4G operators Three, Vodafone, EE, and O2 to probe the impact of 4G rollout on digital TV signals and services.
