The BBC planned to increase their coverage of their DAB multiplex to at least 92% of the population by adding 61 new transmitters to their existing coverage. BBC Asian Network was due to be axed in around 2011 after plans to close down the station were published and it also contained plans to close 6 Music.[2] Since then 6 Music has been saved from closure after listening figures increased and a campaign was set up on Facebook which had 180,000 supporters.[3]

With the publication of the Delivering Quality First paper, it was proposed that DAB Coverage would be increased to 97% in the near future.[4]
