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 fi nd.
– 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.
