Some 170,000 homes in South East London are to be tested for 4G interference on their digital TV sets as part of the ongoing work to ensure services are not affected by new mobile signals.
The tests will be run around the Greenwich, Lewisham, Southwark and Tower Hamlet areas of London, starting on 15 April.
The tests are designed to discover and help rectify any issues caused by 4G services on the 800MHz band, which sits next to digital TV services in the 700MHz band.
Some £180m has been put aside by the operators to cover the cost of this work, which includes the provision of filters to affected home to stop the interference causing a loss of TV service.
Those in the area that experience any problems with their Freeview service are asked contact at800 by calling 0333 31 31 800 with postcode information and time the interference occurred.
Simon Beresford-Wylie, chief executive of at800, said carrying out such large scale tests will help ensure the issues is tackled before it causes any widespread problems.
“These larger tests are essential to help improve our forecast model and the way we’ll tackle potential issues caused by 4G at 800 MHz,” he said.
“We are extremely grateful to viewers in south east London for their help with these important tests.”
The tests are the second major trials by testing body at800 after its first tests in the Midlands in March. Those trials generated just 15 issues from 22,000 homes tested, far lower than the 120 expected by the organisation.
