The evolution of DAB
Abstract
DAB - already covering 500 million people in 40 countries around the world represents the fully mobile and narrowband (1.7 MHz) terrestrial branch of COFDM broadcasting technologies. Although the family of DAB standards has been growing continuously from its beginnings in the early 90s, several major milestones have been reached by the WorldDAB / WorldDMB Forum, especially within the last three years. The most prominent examples are certainly DMB and DAB+. Those two and further applications, as well as the necessary framework created, are illustrated in this article. The technical perspective is accompanied by an economic one, visualising the growth underway and the promising prospects that lie ahead, based on the substantially extended DAB toolkit.
