What is DMSL?

Established in 2012, Digital Mobile Spectrum Limited (DMSL) is a joint venture of the UK mobile network operators EE, Telefónica (O2), Three and Vodafone. 

Our vision is a disruption free digital life for people across the UK. DMSL helps make this a reality by connecting people to communications and media networks and removing barriers to access.

We specialise in transparently delivering complex programmes with multiple public and private stakeholders. Utilising our expertise in radio modelling, customer experience and TV coverage planning, we support our stakeholders in achieving their shared objectives through our TV interference mitigation, spectrum clearing and rural connectivity programmes.

DMSL was set-up to run the at800 support programme and has managed this work since 4G at 800 MHz services began operating in the summer of 2013. Our work on this programme is overseen by a board representing viewers, broadcasters, Ofcom and the Department for Digital, Culture, Media, and Sport. This 4G/TV Co-existence Oversight Board monitors, advises and reports on our performance.
