Radio quiet zone

A map showing the extent of the United States National Radio Quiet Zone.

A radio quiet zone is an area where radio transmissions are restricted in order to protect a radio telescope[1] or a communications station[2] from radio frequency interference. Equipment that can cause interference includes mobile phones, television transmitters, and CB radios, as well as other electrical equipment.[1]

Quiet zones are located in areas that are sparsely populated. They may be divided into zones with different levels of protection. They may be enforced by government legislation.[1]

Formal radio quiet zones exist around many observatories,[3] including the Murchison Radio-astronomy Observatory in Australia,[1] the National Radio Astronomy Observatory and the Sugar Grove Station in West Virginia, United States (the United States National Radio Quiet Zone).[2]
