Changes to regulations mean wireless mics that currently use radio waves in the 694–820 megahertz (MHz) range are no longer permitted to be operated from 1 January 2015.

From 1 January the 694–820 MHz range will be used to deliver advanced 4G mobile broadband services and wireless mics users need to be ready. Wireless mics that currently use radio waves in the 694–820 MHz range must be retuned (if retuning is possible) or upgraded to allow operation in a different band (if the device cannot be returned).
