Who is at800?

at800 is a programme run by Digital Mobile Spectrum Limited. It was set up to ensure that viewers who rely on Freeview for TV can continue to receive it, or are offered a suitable alternative, when 4G mobile services at 800 MHz are activated in their area.

For households that do not have satellite or cable television, where 4G at 800 MHz is diagnosed as causing interference to Freeview, we will restore your television service to its previous quality within ten working days of you contacting us.

at800 has a total budget of £180 million paid for by mobile operators that won 4G licences at the 800 MHz frequency band (EE, Three, Telefónica UK (O2) and Vodafone). The operators’ contributions to at800 are separate from, and on top of, the sums they paid to win their operating licences.

To ensure we deliver a high quality service, we report to the 4G/TV Co-existence Oversight Board representing consumers, broadcasters, mobile operators and Ofcom. It monitors, advises and reports on our performance to the Department for Digital, Culture, Media and Sport (DCMS).
