BBC National DAB is a digital audio broadcasting multiplex in the UK, for a number of radio stations which have UK wide coverage. The multiplex is owned and operated by the BBC and is transmitted from a number of transmitter sites across the country; it only carries BBC radio stations.
As of the end of 2017, more than 97% of the UK's population are within reach of the multiplex following the completion of the switching on of a fourth set of new transmitters over the previous two years which had seen the reach increase from 93%.[2] Any further expansion of DAB radio is awaiting a decision by Government on any possible digital radio switchover.

"Pop-up" services[edit]
The BBC has experimented with short-term "Pop-up" digital radio stations, each broadcasting for approximately four days at a time, covering music festivals and other special events. The first to broadcast was BBC Radio 5 Live Olympics Extra in 2012, then BBC Radio 2 Eurovision launched for the first time in 2014, and was joined by BBC Radio 2 Country, BBC Music Jazz in 2015 and BBC Radio 2 50s in April 2016. When these temporary stations are on air, there is normally a reduction in bit rate of their parent station.

Station closures[edit]
BBC Asian Network was due to be axed in around 2011 after plans to close down the station were published. The BBC also planned to close 6 Music.[3] Since then both stations have been saved from closure – 6 Music was retained after listening figures increased and a campaign was set up on Facebook which had 180,000 supporters.[4]
