Approximately 170,000 households and business addresses in parts of Greenwich, Lewisham, Southwark and Tower Hamlets have been contacted and alerted to the test by at800, the consumer arm of the organisation set up by the mobile phone operators to mitigate disruption to Freeview reception when new 4G services go live later this year.
The test follows a smaller, first test in the Black Country last month, which indicated that viewers using amplifiers would be more likely to be hit by TV interference from 4G. In the Black Country, less households than expected were affected and at800 will be hoping for a similar result from the latest test.
Only 4G mobile services using the 800 MHz frequency band previously used for TV services pose a threat to Freeview reception due to their proximity to remaining Freeview services. Existing 4G services operated by EE use different frequencies.
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." Viewers in South East London who think their Freeview reception has been affected by 4G interference from Monday 15th April can call 0333 31 31 800.
