(1) The spectrum plan recognises that certain radiocommunications receivers used for radio astronomy services operate in, and adjacent to, the 2.3 GHz band (see Australian footnote reference AUS87 in the spectrum plan). (2) The site located in remote central Western Australia, near Boolardy, 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 2.3 GHz spectrum licences.
