DAB Digital Radio

The UK has many layers of DAB Digital Radio coverage. There are three national multiplexes (one from the BBC and two from commercial radio), most areas have a local multiplex (covering a similar area to the heritage BBC local station on FM) and then there are some regional multiplexes too.

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 around 60 operational regional and local multiplexes across the UK, and these are licensed by Ofcom (see www.ofcom.org.uk).

You can find out about the services and areas covered by using the navigation bar on the right.

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.
