Important Changes To Wireless System Requirements - Digital Dividend
The Australian government has recently sold off a chunk of the UHF frequency spectrum for telecommunications purposes. This means that the legal operating frequency for personal broadcasting has changed.
As of 1st of January 2015, any broadcasting system operating in Australia, including wireless microphones and other wireless audio systems, must now operate between 520-694MHz. Not only is this a legal requirement, but an operational requirement to prevent interference that can be picked up in commercial broadcasting frequency ranges.
While 520-694MHz is the general frequency range for operation without needing approval, the available frequencies bands do vary by location. To check available frequencies for your area visit the following website: http://www.frequencyfinder.com.au/
