Why Digital Radio?

The big challenge is: How can we get more stations and better sound quality in the existing AM/FM radio bands? Digital radio answers this by providing much better sound quality, virtually no interference from other transmissions, and many more stations in the same bandwidth. Plus it's robust at lower transmission powers and provides datacasting services like iTunes song tagging and real-time traffic updates.
