14 Background

(1) The spectrum plan: (a) recognises that certain radiocommunications receivers used for radio astronomy operate in the frequency band 2500 MHz to 2550 MHz (see Australian footnote reference AUS87); and (b) allocates the frequency band 2655 MHz to 2690 MHz to, among other things, radio astronomy as a secondary service; and (c) allocates the frequency band 2690 MHz to 2700 MHz to, among other things, radio astronomy as a primary service.

Note: For primary services and secondary services, see sections 5, 7 and 12 of the spectrum plan.

(2) The site located in remote central Western Australia identified for radio astronomy use has been protected by the establishment of the ARQZWA across the radiofrequency spectrum from 70 MHz through to 25.25 GHz. The location of the site, and the definition of the ARQZWA, can be found in the Radiocommunications (Australian Radio Quiet Zone Western Australia) Frequency Band Plan 2023. An area within 70 km of the site has been excluded from the geographic area of the 2.5 GHz band spectrum licences.
