What is Digital Radio?

Digital radio is the transmission and reception of sound processed into patterns of numbers, or “digits” – hence the term “digital radio.” Digital radio reception is more resistant to interference and eliminates many imperfections of analog radio transmission and reception. Digital radio receivers also exist, that decode analog radio signals using digital electronics. Digital radio is free and broadcast over the airwaves like AM & FM.

Internet radio services are streamed via a one-to-one connection from your internet service provider. Depending on your internet service plan, they will incur a download cost. Free-to-air broadcast radio stations also generally stream their services – including new digital radio services – so you can listen online or on-air via digital.

In addition to audio broadcasts, digital radio offers simultaneous data services to listeners.

You could program your digital radio receiver to display weather updates, traffic reports, and other news.
