DAB digital radio can be broadcast on a wide number of frequencies. There are both terrestrial and satellite allocations for Digital Audio Broadcasting (DAB). Currently the main frequencies where it is being deployed are within the Band III (Band 3) frequencies. Here a number of channels have been allocated. A complete table of the channels is given below, although in many countries the full number of channels is not available. Within the UK, the DAB multiplexes are being broadcast on channels 11B through to 12D inclusive.
Although it may appear that comparatively few channels are available, each multiplex is able to carry many stations. If high quality audio is required then fewer stations can be accommodated. However it is often possible to accommodate around four or five high quality broadcasts along with several lower quality ones. In addition to this data can also be carried.
