The Mid-West Radio Quiet Zone ( RQZ ) is a protection zone for radio equipment in Australia .
It is located in the state of Western Australia , 200 km east of Meekatharra and covers around 70,000 km². The center of the Mid-West Radio Quiet Zone is formed by the geographic coordinates 26.704167 ° S 116.658889 ° E (date GDA94 ), the core zone has a radius of 70 km, the buffer zone from 70 to 150 km.
In 2005, the Murchison Radio-astronomy Observatory (MRO) began to establish a radio restriction area for the Murchison Widefield Array (MWA) radio telescope, which is currently under construction . The protection zone was requested for radio silence in the frequencies 70 MHz to 25.25 GHz in the vicinity of the radio telescope location, established on April 11, 2005 as part of the Australian Radiofrequency Spectrum Plan and legally binding in 2011 in accordance with the Radiocommunications Act 1992. It is thus under the supervision of the Australian Communications and Media Authority (ACMA).
With the establishment of such a large protection zone in a largely sparsely populated area, the prerequisite was also created to advertise Murchison as the location for the South African-Australian-New Zealand Square Kilometer Array (SKA), for which the Australian SKA Pathfinder telescope (ASKAP) of the Commonwealth Scientific and Industrial Research Organization (CSIRO) is operational. This is built at Boolardy .
The restrictions are moderate compared to such protection zones that serve military installations and are limited to the astronomically necessary areas: VHF radio cannot be received, land radio, emergency radio and also the School of the Air - the radio lessons for that Australian outback - are possible. Cell phones should remain switched off.
