400 MHz band plan

The 400 MHz  band plan was updated in 2012 to reflect the revocation of the 500 MHz spectrum licence designation where the segments previously spectrum licensed reverted to apparatus licences. This update also gave greater visibility to rail industry use of the band and provided channels for single and two frequency area wide use.

The bands covered by this plan are heavily used for land mobile applications. They are also used for single-channel fixed services, maritime mobile services and, in rural areas, wideband fixed services.

The 400 MHz  band plan was made in 1995, and updated in 1997, to consolidate earlier planning arrangements for radiocommunication services in the two bands 403–420 MHz and 450–520 MHz. The plan was updated in December 2000 to clarify existing former ACA policy on the use of single frequency segments of the band for high-power and low-power land mobile applications.

The plan was amended in December 2002 to provide new opportunities for point-to-multipoint applications in segments allocated for land mobile use. Also, the plan was restructured to more appropriately present policy and historical information.

In response to a review of the 400 MHz band, a wide range of changes were introduced, including the adoption of 12.5 kHz channels throughout the narrowband channel raster (with advice on channel splitting for 6.25 kHz if required), realignment of segment boundaries and restructure of 450–470 MHz to accommodate a 10 MHz duplex frequency split. Segments were set aside to be used exclusively for federal, state and territory government purposes.
