About DAB

About Digital Audio Broadcasting (DAB)

DAB digital radio is a new way of broadcasting radio via a network of terrestrial transmitters. It provides listeners with more choice and information delivered in crystal clear, crackle- free sound quality.

–The technology allows the receiver to lock on to the strongest signal it can ﬁnd.

–With DAB digital stations there are no frequencies to remember, and sets are tuned by station name, so there’s no returning on the move.

What is a multiplex?

Digital radio operation is made up of a single block of frequencies called a multiplex. Each multiplex works within a frequency spectrum, such as Band III for DAB broadcasts.

DAB BROADCASTERS AND DLS

Each DAB broadcaster (or multiplex operator) also provides text and audio data services. Some programmes are supported by Dynamic Label Segments (DLS).This is data which you can read as scrolling text on your DAB radio display. Some stations transmit the latest news, travel, and weather, what’s on now and next, website addresses and phone numbers.
