First things first – what is DAB radio?
DAB radio stands for digital audio broadcasting radio – so, it doesn’t rely on analogue.
Analogue is what you know as FM, AM or long wave radio.
Analogue was the original way that radios used to broadcast. This system relies on a signal transmitted by waves through the air. (There’s a lot of physics that goes into this - and there’s loads of places on the internet that will explain if you’re interested.)
And although analogue has been and always will be a fantastic invention, the digital era has brought some improvements – this is when DAB radio was born.
Why does it matter?
Eventually, everything will be going over to digital. That’s still a little way off realistically, but it always helps to jump the gun on these things.
So, if you’re looking for a new car and don’t want to deal with the headache of updating your radio when it all eventually changes over, check and see if it’s got DAB before you buy.
- You get more stations, especially in city centres. This is where the local stations usually sit, so you might be able to tune in to a great frequency without knowing it existed!
- You see the stations by names, not confusing frequencies – which means you can change stations as much as you want and explore.
- Most DAB radios come with FM too
- DAB radios tune themselves!
The only one worth mentioning might be the decline in sound quality – especially if you have a sophisticated sound system in your motor.
This is just because the bit rate is a little lower with DAB radio in order to get more stations broadcasting at the same time.
