BEST BUYING GUIDE FOR DIGITAL RADIO
Simply put, digital radio allow broadcasters to offer analogue stations simulcast in digital quality. It also has the scope to include new digital stations. It has robust modulation which means is has capability in mobile environments including vehicles and public transport.
Digital radio is now the most widely internationally accepted radio standard.
It is on air in more than 40 countries.
Let’s talk about the difference between the frequencies, AM, FM and DAB+.
AM used longer wavelengths in the medium wave bands. This allows the signal to travel further, however, this band is plagued by interference particularly in dense urban areas.
FM uses the VHF Band II (88-108MHz) a higher frequency offering better sound quality than AM however, this frequency suffers from multipath interference and is overloaded so it limits the ability for the radio to grow with technology or offer improved features or functionality.
DAB+ is a product of the technical age we are in and offers some pretty advanced transmission. It too uses higher frequency which will work well in range and this is something which needs to be established. Are you in the DAB+ range?
