Mixed Signals

Some TV viewers may notice problems starting on Monday, 15 April.

As part of the rollout of the next generation of mobile telephone services (known as 4G), engineers will be running tests in South East London to see what impact the use of certain frequencies will have on Freeview TV reception.

If you live in the south east London area and notice problems with your Freeview service from Monday, 15 April, please contact the company responsible for running the tests, at800, by calling 0333 31 31 800. You will be asked for your postcode, the type of interference and the time it occurred. at800 has a team of professional aerial installers and testing units in the area that will respond to calls from viewers, visit addresses reporting problems and restore Freeview as soon as possible. It is possible that you may need an at800 filter - a small device, smaller than a pack of cards, which when installed correctly will block 4G frequencies at 800 MHz, enabling viewers to receive and watch Freeview as normal.

at800 has contacted approximately 170,000 household and business addresses in parts of Greenwich, Lewisham, Southwark and Tower Hamlets. If you’ve not been contacted directly through the post any interference to your Freeview service is unlikely to be due to the 4G test, but contact them to be sure. Freeview is the television that viewers can receive through their aerial; TVs connected to a cable or satellite service will not be affected.

The purpose of the tests is to ensure that viewers continue to receive Freeview when 4G mobile services at 800 MHz are launched later this year. Further details can be found on the at800 website.
