Viewers in south east London are being asked to report any interference to their television viewing next week as part of a trial of 4G services on frequencies in the 800MHz range.
The trial that covers approximately 170,000 household and business addresses in parts of Greenwich, Lewisham, Southwark and Tower Hamlets is being run by at800, the telco funded organization designed to alleviate the potential problems between existing TV transmissions and the so-called 4G broadband services.
It follows last month’s small-scale test in the Cradley Heath and Rowley Regis area of the West Midlands.
Viewers who believe they are suffering interference are being asked to call a freephone number established by at800, which is also alerting consumers to the test.
Simon Beresford-Wylie, chief executive of at800, said “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. We are extremely grateful to viewers in south east London for their help with these important tests.”
Filters are being made available to counter the effects of interference that in most circumstances is restricted to DTT.
