What Is DAB + Radio?
What Is DAB + Radio?
Digital Audio Broadcasting (DAB) is the third generation of broadcasting after AM and FM traditional analog broadcasting-digital signal broadcasting. It provides sound close to CD quality, with anti-noise, anti-interference, and anti-fading of radio waves. , Suitable for high-speed mobile reception and other advantages, to ensure the quality of the received signal when fixed, carried and mobile.
Despite the rise of streaming, radio is far from dead. In fact, it’s actually healthier than ever- all thanks to DAB radio. Freed from annoying static and the limited number of AM and FM stations available, digital technology has brought the humble radio well and truly into the twenty-first century.
You might think that digital radio is a fairly new phenomenon, but it’s actually been around for quite a while. Test transmissions began back in 1990, before digital radio as we know it was launched to the public in 1995. Since then, though, the technology behind digital broadcasting has improved massively. DAB+ is being launched across many parts of the world to give listeners better sound quality. Currently, it hasn’t taken off in the UK just yet. Only a handful of stations broadcast this way, with the vast majority using standard DAB. However, it’s likely that more and more broadcasters will make the switch to DAB+ in the next few years. To make sure your new purchase is futureproof, keep an eye out for DAB+ functionality when choosing a DAB radio.
How does digital radio work?
As you probably already know, FM radio is sent out as a transmission on a particular frequency. Each station is only given a very narrow frequency, so they don’t overlap and interfere with each other. If you stray outside that frequency, you'll quickly be met by a wave of static. DAB radio, though, works in a very different way. The digital transmission is made up of a string of ones and zeroes. Since there are no frequency bands to stick to, that same signal can be sent out multiple times. This means that your radio has more chances to pick up the signal- making DAB radio far more reliable than its FM counterpart.
More than that, though, the way DAB signals are sent brings some extra benefits, too. For one thing, the wider band means that stations can send out additional information along with the song. This includes things like the name of the show and song that are currently playing- especially useful if you like to pick up new music from the radio and don’t quite catch the track name at the end. DAB signals are also better able to work around obstacles between your radio and the transmitter, like large buildings, and they carry their own protection against transmission errors.
