8 In-band interference

(1) In-band interference to a 2.5 GHz mid band gap receiver, caused by a radiocommunications transmitter operated under an adjacent spectrum licence, is managed by the core conditions imposed on spectrum licences under section 66 of the Act and the device boundary criterion. (2) In-band interference to a 2.5 GHz mid band gap receiver, caused by a radiocommunications transmitter operated under an apparatus licence, is managed as if the transmitter were operated under a spectrum licence. The device boundary criterion should be applied to such radiocommunications transmitters, affording 2.5 GHz mid band gap receivers the same level of in-band protection from apparatus licensed radiocommunications transmitters as they are afforded from radiocommunications transmitters operated under adjacent spectrum licences. (3) Application of the device boundary criterion manages in-band interference. The device boundary criterion incorporates emission limits that provide reasonable protection within the geographic area of a spectrum licence. Emission limits are also used to manage out-of-band interference, but these do not provide protection along the frequency boundaries of a spectrum licence. Because of the nature of out-of-band interference, emission limits cannot be used to provide protection from out-of-band interference for radiocommunications devices that are located near each other.

Note: Example: Radiocommunications devices that are located near each other include devices located at multi-operator sites.

(4) The ACMA does not intend to act in relation to in-band interference to a 2.5 GHz mid band gap receiver caused by a radiocommunications transmitter operated under a class licence where the operation complies with all relevant conditions of the class licence.
