Issue 18: Trends and capabilities of the DAB family of standards

UntitledToday and into the future

Since its launch, digital radio has seen an evolution in the manner in which it is understood, applied and utilised by all sectors of the radio industry.Successive governments who have adopted the DAB family of standards have understood its capacity to free up much valued spectrum, fulfill their responsibilities to provide diverse citizens with relevant, accessible cultural services and to provide the fundamentally important service of warning citizens in times of disaster.

Manufacturers of DAB chips and receivers have also seen an evolution in the manner in which devices and their capabilities have evolved. Technological limitations in early silicon chips and DAB receivers limited their perceived benefits over analogue radios. This perception has seen a dramatic shift in the last few years. Silicon chip manufacturers have invested heavily in the creation of cheaper, smaller and more energy efficient chips. This has had a positive knock on effect on receiver types, size, design and capabilities, which in turn greatly increases the variety of ways in which broadcasters are able to provide additional services to listeners.
