Licensed point to point systems require a co-ordinated license from the Australian Communications & Media Authority (ACMA). They operate in a variety of bands from 6 Ghz for long links (up to 50 Km) to 38 Ghz for short links (up to 4Km). They range from 50 Mbps full duplex to 500 Mbps full duplex transmission. License costs depend on the spectrum used and the area of operations.
