What exactly is DAB?

DAB stands for Digital Audio Broadcasting. DAB is a digital radio system, which was developed by the Eureka 147 Project. It offers near CD-quality sound, more stations, additional radio and data services and therefore wider choice of programs, the ease of tuning and interference-free reception for the listener, plus the information potential of data, graphics and text. For the broadcaster, DAB provides a means of reaching listeners with sound quality on an equal footing with the CD player, and the ability to offer extra, potentially revenue-creating, services. Transmission will also be cheaper. For other areas of industry, there will be a new market for receivers and transmission equipment.
