The term 4G refers to the fourth generation of mobile communications standards. 4G provides faster mobile internet access to laptops, smartphones and other mobile devices .
We are making it easier for the communications and telecoms industries to grow, while protecting the interests of citizens by supporting the introduction of 4G mobile communication to the UK.
Ofcom is currently auctioning radio spectrum licences for 4G mobile communications in the 800 MHz and 2.6 GHz bands.
4G transmissions in the 800 MHz band could cause interference to terrestrial television services. Nine in 10 households will not experience any interference. But Ofcom estimates that up to 2.3 million households might be affected and that approximately 900,000 of these households use terrestrial television as their primary means of watching TV .
Working with Ofcom, we want to resolve the effects of interference so that television viewers do not lose access to television services.
The existing Mobile Network Operators have set up a company, Digital Mobile Spectrum Limited (DMSL), to help households affected by interference once the spectrum auction has concluded. The ownership of DMSL will change after the auction to reflect those who successfully win 800 MHz licences.
For the majority of households, the interference will be resolved by fitting a filter. Find out more about the 4G interference assistance scheme.
An independent group, the TV/4G Coexistence Oversight Board has been set up to give support and guidance to DMSL.
The Board is made of an independent Chair, two independent members, representatives of the successful 800 MHz licensees (currently the existing Mobile Network Operators) and an equal number of representatives of the terrestrial television broadcasters. DCMS, Ofcom and DMSL have non-voting members of the Board. The Board’s Chair reports to Ed Vaizey and to Ofcom.
