Space system frequency bands

This page lists the internationally agreed frequency bands that have been reserved for use by space based networks, and links to more information about Australian spectrum use. Read on for more.

Planned frequency bands

The Broadcasting Satellite Service Plan

The following bands have been reserved internationally for broadcasting satellite service operations, as set out in Appendices 30 and 30A of the International Telecommunications Union (ITU) Radio Regulations:

  1. 11.7 to 12.5 GHz (space to Earth) Region 1

  2. 12.2 to 12.7 GHz (space to Earth) Region 2

  3. 11.7 to 12.2 GHz (space to Earth) Region 3 (the region in which Australia is located)

  4. 14.5 to 14.8 GHz in Regions 1 and 3

  5. 17.3 to 18.1 GHz (Earth to space) Regions 1 and 3

  6. 17.3 to 17.8 GHz (Earth to space) Region 2

The Fixed Satellite Service Allotment Plan

As set out in Appendix 30B, the ITU Radio Regulations establishes arrangements for fixed satellite service operations in the following bands:

  1. 4.5 to 4.8 GHz (space to Earth)

  2. 6.725 to 7.025 GHz (Earth to space)

  3. 10.7 to 10.95 GHz (space to Earth)

  4. 11.2. to 11. 45 GHz (space to Earth)

  5. 12.75 to 13.25 GHz (Earth to space)

Changes to the BSS or FSS Plans

Coordination is not required for existing satellite networks or new satellite networks operating within the planned satellite bands. All other satellite bands are unplanned and, therefore, proposed networks or networks requiring modification have to go through a process of coordination and notification with the ITU. Contact the ACMA for more information.

Unplanned frequency bands
