Help / DAB / Getting StartedWhat is DAB? Digital Audio Broadcasting or 'DAB digital radio' has been developed by a consortium of manufacturers and broadcasters. The BBC pioneered DAB digital radio and was the first broadcaster in the UK to build a transmission network and start broadcasting in 1995. DAB Digital Radio Explained How does it work?DAB radio works by using both MPEG and COFDM (Coded Orthogonal Frequency Division Multiplex) technology which converts the music or speech from analogue signal into digital (binary) code. How is this different from FM?The sort of interference which commonly disturbs FM reception (caused by radio signals bouncing off buildings and hills) is eliminated within DAB signals. DAB technology is able to filter out interference and correct signal errors.
