Digital Audio Broadcasting (DAB) is designed for delivery of high-quality digital audio programmes and data services for mobile, portable and fixed reception from terrestrial transmitters in the Very High Frequency (VHF) frequency bands.

The DAB system is designed to provide spectrum and power efficient techniques in terrestrial transmitter network planning, known as the Single Frequency Network (SFN) and the gap-filling technique. The DAB system meets the required sharing criteria with other radiocommunication services.

DAB is the most widespread terrestrial broadcast digital radio standard offering broadcasters the opportunity to enhance their radio offerings, meet the higher quality expectations of listeners and to reduce energy consumption.
