DAB+ Radio. What is Digital Radio Broadcasting?
Krzysztof Fiedorek
Digital radio broadcasting technology, compared to traditional analog radio, provides higher sound quality, better resistance to interference, and more additional features during transmission. However, it’s not without drawbacks and raises concerns among broadcasters.

illustration: bing.com/createThe latest generation of Digital Audio Broadcasting technology, known as DAB+, uses digital audio encoding to transmit radio signals. Unlike analog radio, which uses amplitude modulation (AM) or frequency modulation (FM), DAB+ uses digital frequency modulation (DFM). DFM allows for transmitting more data using the same amount of bandwidth, providing higher sound quality and better resistance to interference.
Advantages of DAB+
Higher sound quality. DAB+ offers better sound quality than analog radio. DAB+ can transmit audio at resolutions up to 24-bit/96 kHz, delivering clarity and detail unavailable with analog radio.
Better interference resistance. DAB+ is more resistant to interference than analog radio. This means cleaner and more audible sound in areas where signal interference occurs.
More features. DAB+ allows broadcasters to offer additional services, such as:
- text accompanying audio
- subtitles
- weather information
- traffic information
- news updates
Disadvantages
Hardware requirements. To listen to DAB+ radio, you need a DAB+ receiver. DAB+ receivers are available on the market but may be more expensive than analog radio receivers.
Availability. DAB+ is still in the implementation phase in many countries, including Poland. Not all radio stations offer DAB+ yet, and DAB+ coverage may be limited. According to Poland’s National Broadcasting Council:
- 94% of new cars in Europe come with built-in DAB+ digital radio
- in Poland, this percentage is 92%
DAB+ is a technology with great potential that could change the way we listen to radio. Whether it will become a universal radio standard will impact radio’s future as a medium.
Improving DAB+ receiver availability and expanding DAB+ coverage are the main challenges facing this new technology today. If successful, DAB+ could paint the future of radio in entirely new colors.
