What is DAB Digital Radio?
Stations broadcast on DAB via a multiplex. A multiplex is a collection of audio and data services which are bundled together into a single frequency. The average multiplex has 1.2 megabits of usable capacity which usually allows for between 8 and 14 stations, more depending upon how many kilobits (‘kbits’) are contracted to each station.
There are currently 46 operational regional and local multiplexes across the UK, and these are licensed by Ofcom (see www.ofcom.org.uk). Since early 2007, Ofcom has been advertising a new tranche of DAB digital radio multiplexes to fill in the gaps in existing coverage. 13 new local multiplexes are expected to launch over the next 18 months and there may be further new multiplexes in due course.
Each multiplex provides a range of existing commercial services, as well as new commercial services that broaden choice. In addition, the existing local BBC station is always guaranteed capacity.
