at800 is an organisation set up under Government direction to resolve Freeview TV interference when new 4G mobile phone signals are switched on.
Could this affect you?
Digital TV and 4G mobile services both use parts of the radio spectrum – that is bands of frequencies – to send signals. The 800 MHz frequencies used by some 4G services are next to frequencies used for Freeview. This may cause disruption to your Freeview service. We identify homes at risk of experiencing interference and send a postcard letting them know we can help.
