4  Definitions
 (1) In this instrument:
adjacent channel means a channel with a centre frequency offset on either side of the assigned channel frequency of the occupied channel by a specific frequency relation.
adjacent channel selectivity means a measure of the ability of the radiocommunications receiver to receive a wanted signal without exceeding a specified degradation in output quality due to the presence of an unwanted adjacent channel signal.
area-wide licence has the meaning given in Schedule 1 to the Radiocommunications (Interpretation) Determination 2015.
blocking means a measure of the ability of a radiocommunications receiver to receive a wanted signal in the presence of a high level unwanted interferer on frequencies other than those of the adjacent channels.
emission buffer zone means a zone along the frequency or geographic boundary of a spectrum licence where emission levels of radiocommunications transmitters are reduced to ensure that significant levels of emissions stay within the geographic area and frequency band of the licence.
in-band means:
(a) for a radiocommunications transmitter or radiocommunications receiver operated under a spectrum licence, the frequencies within the frequency band in which operation of those radiocommunications devices is authorised under the licence; and
(b) for a radiocommunications transmitter or radiocommunications receiver operating under an apparatus licence, the frequencies within the lower frequency limit and the upper frequency limit specified in the licence.
intermodulation response rejection means a measure of the ability of a radiocommunications receiver to receive a wanted signal in the presence of two or more unwanted signals with a specific amplitude and frequency relationship to the wanted signal frequency.
out-of-band means:
(a) for a radiocommunications transmitter or radiocommunications receiver operated under a spectrum licence, the frequencies outside the frequency band in which operation of those radiocommunications devices is authorised under the licence; and
(b) for a radiocommunications transmitter or radiocommunications receiver operating under an apparatus licence, the frequencies outside the lower frequency limit and upper frequency limit specified in the licence.
RALI MS 46  means the Radiocommunications Assignment and Licensing Instruction MS 46, Licensing and coordination procedures for area-wide apparatus licensed services in the 26/28 GHz bands, published by the ACMA.

Note: RALI MS 46 is available free of charge on the ACMA website: www.acma.gov.au.
spectrum space means a three dimensional space consisting of a frequency band and geographic area.
Subsection 145(4) Determination means the Radiocommunications (Unacceptable Levels of Interference — 26 GHz Band) Determination 2020.

Note: The Subsection 145(4) Determination is available free of charge from the Federal Register of Legislation: www.legislation.gov.au.
unwanted emissions means any emissions (both out-of-band and spurious emissions) outside the lower and upper frequency limits of a spectrum licence.
unwanted signal means all emissions from any radiocommunications transmitter which is not communicating
