4G interferenceIf 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.
Symptoms for those affected might include a loss of sound, blocky or pixelated images or loss of some or all channels. Only those who watch TV channels on Freeview are expected to be affected; you are unlikely to experience any interference if you watch cable or satellite TV.
Most of the disturbance will be solved by supplying free filters in advance to those affected. The filters will be easy to plug-in and will solve the problem by removing 4G signals before they reach Freeview TV sets or set-top boxes. We think most viewers will be able to fix the problem themselves in a matter of minutes with an at800 filter.
Because cable and satellite users should not be affected by 4G interference, further assistance would only be provided to households relying on Freeview as their primary TV service. Households with cable or satellite would not be eligible for this further free help.
In all instances, we will supply a maximum of one filter per household, which means that you’ll have to pay for any additional filters for secondary TV sets.
at800 will contact all households likely to be affected by before disruption could occur.
