For us video people running with wireless microphones etc, our world is about to become a whole lot more interesting! Currently, a large number of wireless audio systems and devices operate within the frequency range 520-820 MHz. This frequency range is the same as that used by television broadcasting. The wireless audio systems are low power, and are allowed to operate under a Low Interference Poential Device (LIPD) class licence in the unused television channels on the basis of no interference, and no protection from interference.
Television services are currently in the process of changing over from analog to digital. This switch-over will change the ranges of frequencies that television services use, and will therefore affect the spectrum available for wireless audio equipment.
Depending on your location your wireless microphone system may not work. To find out detailed information I’d suggest clicking here to go to the ACMA website.
Also Syntec has released a great frequency finder tool, simply go to www.frequencyfinder.com.au to find the wireless frequencies that you can use in your location.
