Digital Audio Broadcasting - FM HD Radio versus DAB

1 Some countries have implemented Eureka-147 Digital Audio Broadcasting (DAB). DAB

broadcasts a single station that is approximately 1500 kilohertz wide (~1000

kilobits per second). That station is then subdivided into multiple digital streams of

between 9 and 12 programs. In contrast FM HD Radio shares its digital broadcast with

the traditional 200 kilohertz-wide channels, with capability of 300 kbit/s per station (pure

digital mode).

Digital Audio Broadcasting - Reception quality

1 Due to sensitivity to doppler shift in combination with multipath

propagation, DAB reception range (but not audio quality) is reduced

when travelling speeds of more than 120 to 200km/h, depending on

carrier frequency.[http://tech.ebu.ch/docs/techreview/trev_265-kozamernik.pdf Digital Audio Broadcasting (EBU

L band (template) - Digital Audio Broadcasting

1 In the United States and United States territory|overseas territories, the L band is held by the Military of the United States|

military for telemetry, thereby forcing digital radio to in-band on-channel (IBOC)

solutions. Digital Audio Broadcasting (DAB) is typically done in the 1452–1492-

Megahertz|MHz range as in most of the world, but other countries also use very

high frequency|VHF and ultra high frequency|UHF bands.
