Should we really switch from analog FM radio to digital terrestrial radio?
Switching from FM radio to DAB+ offers benefits such as improved sound quality, a wider choice of stations and increased spectrum efficiency, but it is not a necessary or universally desirable step for all listeners or regions. While broadcasters may save costs and gain new services, the switch requires public investment in new equipment, can lead to poorer coverage in some areas, and may not be viable for limited regional services.
Reasons for moving to digital radio
Improved audio quality: DAB+ delivers crystal-clear digital sound, eliminating the static and interference common with analogue FM signals.
Wider station selection: Digital signals allow multiple radio programs to be broadcast on a single channel, significantly increasing the number of stations available.
Additional features: DAB+ radios can display additional information such as song titles, artists and album art, with some capable of broadcasting slideshows and videos.
Spectrum efficiency: DAB technology uses the radio spectrum more efficiently, allowing more services in the same amount of bandwidth compared to FM, which is a major advantage for broadcasters.
Cost savings for broadcasters: Switching off FM can save broadcasters significant costs in terms of transmission and equipment.
Energy efficiency: Digital broadcasting can be more environmentally friendly, offering energy savings compared to FM broadcasting.
Disadvantages and considerations:
Consumer costs: A full switchover requires the public to purchase new DAB+ radios, which can be expensive and inconvenient.
Coverage limitations: While digital broadcasts are resistant to interference, their signal quality degrades rapidly and may fail completely below a certain threshold, while FM reception degrades more slowly over a larger area.
Quality variation: The sound quality of DAB+ can vary significantly depending on the bit rate chosen by the broadcaster. High-quality audio requires a higher bit rate and can result in fewer stations being compressed into a single broadcast signal.
Limited benefit for small stations: DAB+ may not be viable for small, regional stations that serve limited areas and are not covered by the DAB network.
Listener preference: Some listeners may not see the benefit, especially if they already have access to radio via other digital platforms such as cellular data.
