From WIA News for 30 July 2017:
The ACMA looking at microwave spectrum
The Australian Communications and Media Authority (ACMA) is planning for the arrival of the revolutionary 5G mobile technology.
Acting ACMA Chairman, Richard Bean, in a speech entitled ‘Unwired Revolution’, said nearly everyone accepts that standardisation and spectrum harmonisation for 5G technology is still at the formative stage. However, 5G is expected to bring super-fast mobile broadband networks, support the Internet of Things, and be ultra-reliable for applications, including remote control of industrial or medical processes.
The key question is:
What bands are likely to be used for 5G in particular, or wireless broadband more generally?
There will be pressure on all the microwave bands used by Amateur Radio terrestrially and with satellites, with the ACMA already looking at 3.6 GHz, 5.6 GHz and 47 GHz as possible candidate bands.
These ACMA reviews will take some years, but the theme is that spectrum shared by Amateur Radio at present is not certain in this rapidly changing technology world.
This area is closely watched locally by the Wireless Institute of Australia and globally through the International Amateur Radio Union.
