The R&S®

AB+ is now well-established in 35
countries and regions. In some
places, it is used alongside classic
FM services; in others, it is already
the sole medium for terrestrial radio
broadcasting.

When an FM transmitter fails, only
a single radio program within the
coverage area of the transmitter
is
affected. With DAB+, however,
multiple programs are broadcast
by the same
transmitter using
interference, expanded
to
broadcast accompanying images and
text. DAB+ receivers are also capable
of receiving FM radio signals so that
an either/or decision is not required.
An EU directive has mandated
support for DAB+ in all radios that
are installed in new cars. In some
countries
including Germany, this
also applies to higher end radios for
use at home or on the go. Of course,
radio receivers are useless without
broadcast programs to receive. Radio
network operators in some countries
are thus required to maintain DAB+
infrastructure alongside their FM
networks.
