Digital radio makes spherics and crackling interference in radio broadcast a thing of the past. New technologies from Fraunhofer IIS make it possible for digital radio to replace analogue short and medium wave broadcasting around the world. Even local FM transmissions are being converted to digital. As a result, Digital radio listeners benefit from clear reception, a wider range of programming, and additional information via data services without having to pay for a costly Internet connection.
Alexander Zink, researcher at the Fraunhofer Institute for Integrated Circuits IIS based in Erlangen, Germany, would like to provide clarification around a common misunderstanding: »Digital radio works the same way as terrestrial FM radio via air waves, but with better quality, more variety and innovative extra features. Digital Radio is independent of the Internet and available to the listener free of charge.« Together with Martin Speitel, Max Neuendorf and an extensive team, Zink developed several necessary basic technologies, as well as transmission and receiving solutions for digital radio applications. Today, these technologies are utilized around the world in nearly all digital radio systems.
Digital Radio Already Established Worldwide
Digital radio is already implemented throughout the majority of Europe. Many developing countries are in the planning stage to convert from analog to digital for short and medium wave, and the digitalization of local FM broadcasts is in development as well. For instance, India is among the front-runners for digitalization, and on its way to becoming the world‘s largest digital radio market.
