About at800

at800 is an independent organisation created to ensure that all UK viewers continue to receive Freeview, or are offered a suitable alternative, when 4G at 800 MHz is activated in their area.

We are funded by and represent the UK mobile operators who are launching 4G mobile services at 800 MHz: EE, Telefónica UK (O2), Three and Vodafone. Each operator contributes to our funding to enable us to provide corrective support for households whose Freeview services could be affected by the deployment of 4G at 800 MHz, and that use Freeview as their primary TV service.
