Radio microphone changes

Change to radio microphone operating frequencies

The introduction of digital television and the reallocation of the frequency range 698-806 MHz for next generation (4G) mobile broadband has affected the frequencies available for radio microphones.

Radio microphones (and other wireless audio devices such as in-earpieces) are no longer permitted to operate in the 698-806 MHz frequency range (the 700 MHz band). It is also not permitted to sell or supply radio microphones that operate in this frequency range. Radio microphones must operate within the frequency ranges of 502-606 MHz and 622-698 MHz.

Radio microphone users are a secondary user in the spectrum and therefore have to work around the primary user (digital television), utilising unused channels and spaces in the spectrum. Read the full details on the GUSL that radio microphones are licenced to operate on.

Users of radio microphones must either retune their existing radio microphone to a permitted frequency, or if they are unable to do this, replace their existing equipment with equipment that can be operated within the permitted frequencies.

When replacing equipment it is recommended to purchase equipment that can be used on the widest possible frequency range, in order to work around television and other users. This flexibility is important as there is the possibility of a gradual increase in television channels, which will affect the frequencies available in the future. Those operating a radio microphone at a non-permitted frequency may face compliance action.

In 2013, RSM carried out a consultation on these changes.
