Exeter's Small-Scale DAB Multiplex
What is DAB
DAB stands for ‘Digital Audio Broadcasting’ – this is the future of radio here in the UK and in many other countries around the world.
At some point FM as we know it will be switched off. As well as being less prone to interference DAB opens up new opportunities for broadcasters and a dramatic increase in listener choice.
Here at ExeDAB we’re planning to broadcast a wide range of stations for a wide range of tastes, interests, communities and age groups.
How it works
FM radio is sent out as a transmission on a particular frequency. If you tune away from that frequency, you’ll quickly get static. DAB radio works differently. Many stations are sent together on one frequency and the listener chooses their favourite which is allowed through by their radio excluding the others.
The way DAB signals are sent brings some extra benefits, too. For one thing, stations can send out additional information like pictures, song names and other info. DAB signals are also better able to work around obstacles between your radio and the transmitter, like large buildings, and they carry their own protection against transmission errors.
