Results of our big survey in 2021: We asked the question, which band is the most used band? (10 frequency bands between 174 to 2.5 GHz were listed).

85 % equipment use is the band 470 – 694 MHz, while the band 694 MHz – 790 MHz is still used by 35 % of the users (although this band will be given to Mobile IMT, it is still usable in many countries).

90 % of the participants stated that the band 470 – 694 MHz is their most preferred band.

PMSE users and manufacturers consider the band 470-694 MHz as the core band of audio PMSE, the access must be ensured beyond 2030. The frequency bands 823-832 and 863-865 MHz are limited in their bandwidth receiving a higher RF noise floor from out-of-band emissions from adjacent bands.

Audio PMSE applications with high quality requirements cannot be supported with the bands above 694 MHz and therefore use only the frequency band 470-694 MHz.
