DAB means Digital Audio Broadcasting

What's it? DAB or DIGITAL AUDIO BROADCASTING is one of the biggest innovations in the radio field,which allows transmission of transmissions in a cleaner way using the digital signal. Advantages: Better audio quality, more user-friendly, additional content (text, images) that support the audio and potentially even new channels, as happened for the TV Disadvantages: coverage is not guaranteed everywhere

It is also useful because better management of the radio spectrum ex: 1 frequency 1 FM channel 6 DAB channels /18 DAB+ channels

When & where is born The first digital radio stations appeared in Norway and in England in 1995

DAB e DAB+:what's the difference?

DAB+ DAB+ appeared in 2006 DAB+ made it possible to transmit more networks at better sound quality than DAB

DAB coverage in Italy poor coverage above all in southern Italy
