4G/TV Co-existence Oversight Board

The 4G/TV Co-existence Oversight Board oversees the help being offered to consumers affected by television interference caused by the rollout of 4G (superfast mobile internet) in the 800 MHz spectrum band.

The Board reports to the Department for Culture, Media and Sport (DCMS) and Ofcom, the independent regulator and competition authority for the UK communications industries.

The help scheme is delivered by a private company, Digital Mobile Spectrum Limited (DMSL), which is owned by the 800 MHz licensees. DMSL uses the name ‘at800’ in its communications with the public.

The original help scheme was revised in February 2014 to provide an even higher standard of service to viewers affected by 4G interference.

  • Roger Darlington, non-executive member with expertise in consumer matters
  • William Webb, non-executive member with expertise in technical and economic matters

4 representatives of the 800 MHz licensees:

  • Inge Hansen, Head of Spectrum Strategy, Everything Everywhere
  • Robin Vernon, Regulatory Manager, Telefónica (O2)
  • Greg Thompson, Radio Strategy & Architecture Manager, Three
