Wireless audio transmitters that operate in the 694-820 MHz band will be illegal to use in Australia from 1 January 2015 because the federal government has sold that range of frequencies.
Wireless audio transmitters include microphones, in-ear monitoring systems and public announcement systems, which are commonly used by training organizations.
If your organization owns wireless audio transmitter it is recommended to check at which frequency they operate since the 700 MHz band is used by most current devices. In case you own any affected equipment, you will have to replace them before the end of December 2014.
If you are planning to purchase or upgrade any wireless audio transmitter confirm that they operate in a band outside the 694-820 MHz.
