Following tests conducted across the country, at800, the organisation responsible for protecting Freeview when 4G at 800 MHz is rolled out across the UK, has provided a new estimate of the likely scale of the impact.  If national rollout reflects the results seen during its tests, at800 expects no more than 90,000 households, with Freeview as their primary TV service, to experience disruption caused by 4G at 800 MHz. This is a small fraction of early estimates.

at800 has now sent postcards to households in London and the surrounding areas in preparation for the activation of 4G at 800 MHz masts over the coming weeks and months. at800 is also sending postcards to other areas of the UK ahead of masts switching on.

In London, in particular, Freeview received from the Crystal Palace transmitter is unlikely to be affected by mast activation because of the strong terrestrial television signal and its relatively large frequency separation from 4G at 800 MHz. However, at800 is running a publicity campaign to ensure anyone who does experience new disruption to their Freeview service knows how to get in touch.
