GPS navigators with DAB receiver

 

— the presence of a DAB receiver in the design of the navigator.

The abbreviation DAB stands for Digital Broadcasting. This is the key difference between this standard and other popular formats (including FM known to many): the radio signal during such broadcasting is transmitted in digital form, using the MP2 codec.

Digital broadcasting has a number of advantages over analogue broadcasting. So, in a similar way, you can achieve a greater range with a lower power of transmitters, and without loss in quality. Actually, the sound quality in DAB does not depend on the strength of the received signal; to be more precise, weak interference does not affect its quality, and if the power drops to a critical level, the sound is not distorted, but disappears completely. The disadvantage of this standard is its relatively low prevalence; therefore, before buying a navigator with DAB, it is worth checking whether there is a digital broadcast in your area and what are the technical requirements for receivers for such broadcasting.
