Part 1 Preliminary

1 Name These are the Radiocommunications Advisory Guidelines (Managing Interference to Spectrum Licensed Receivers – 850/900 MHz Band) 2021.

2 Commencement This instrument commences at the start of the day after the day it is registered on the Federal Register of Legislation.

Note: The Federal Register of Legislation may be accessed free of charge at www.legislation.gov.au.

3 Revocation The Radiocommunications Advisory Guidelines (Managing Interference to Spectrum Licence Receivers – 800 MHz Band) 2012 (F2012L01774) are revoked.

4 Authority This instrument is made under section 262 of the Radiocommunications Act 1992.

5 Definitions (1) In this instrument: 850 MHz band means the following frequency bands: (a) 814 MHz to 845 MHz; (b) 859 MHz to 890 MHz. 900 MHz band means the following frequency bands: (a) 890 MHz to 915 MHz; and (b) 935 MHz to 960 MHz. Act means the Radiocommunications Act 1992. adjacent channel, in relation to a particular channel, means a channel with a centre frequency offset on either side of the assigned channel frequency of the particular channel by a specific frequency relation. adjacent channel selectivity, in relation to a radiocommunications receiver, means a measure of the receiver's ability to receive a wanted signal without exceeding a specified degradation in output quality due to the presence of an unwanted signal from an adjacent channel. adjacent spectrum licence, in relation to a spectrum licence, means another spectrum licence that has either a common frequency boundary or a common geographic boundary adjacent to that licence. blocking, in relation to a radiocommunications receiver operating on a particular channel, means a measure of the ability of the receiver to receive a wanted signal in the presence of a high power unwanted signal on frequencies other than those of the adjacent channels to the particular channel. emission buffer zone, in relation to a spectrum licence, means a zone along the frequency or geographic boundary specified in a spectrum licence where emission levels of radiocommunications transmitters are reduced to ensure that significant levels of emissions stay within the geographic area and frequencies of the licence. in-band means, for a radiocommunications device operated under a spectrum licence or apparatus licence, frequencies within which the device is authorised to operate. intermodulation response rejection, in relation to a radiocommunications receiver, means a measure of the ability of the 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. mobile transmitter means a radiocommunications transmitter that is only designed or intended for use while in motion or during halts at unspecified points on land or sea. out-of-band means, for a radiocommunications device operated under a spectrum licence or apparatus licence, a frequency on which the device is not authorised to operate. RALI FX 22 means the Radiocommunications Assignment and Licensing Instruction FX 22 Frequency assignment requirements for the fixed service in the 800 MHz band, published by the ACMA. Note: RALI FX 22 is available, free of charge, on the ACMA website at www.acma.gov.au. RALI LM 8 means the Radiocommunications Assignment and Licensing Instruction LM 8 Frequency Assignment Requirements for the Land Mobile Service, published by the ACMA. Note: RALI LM 8 is available, free of charge, on the ACMA website at www.acma.gov.au. spectrum space means a three-dimensional space consisting of a frequency band and geographic area. unwanted emissions, in relation to a spectrum licence, means any radio emission (whether an out-of-band emission or a spurious emission) outside the lower frequency limit and upper frequency limit specified in a spectrum licence. unwanted signal means any radio emission from any radiocommunications transmitter that is not communicating with the radiocommunications receiver used for a service protected by this instrument. wanted signal means a radio emission from a radiocommunications transmitter designed for communication between the transmitter and a radiocommunications receiver used for a service protected by this instrument. Note: A number of other expressions used in this instrument are defined in the Act, including the following: (a) ACMA; (b) apparatus licence; (c) class licence; (d) core condition; (e) frequency band; (f) interference; (g) radiocommunications device; (h) radiocommunications receiver; (i) radiocommunications transmitter; (j) Register; and (k) spectrum licence. (2) Unless the contrary intention appears, terms used in this instrument that are defined in the Radiocommunications (Unacceptable Levels of Interference — 850/900 MHz Band) Determination 2021 have the same meaning as in that determination. Note: The following terms that are used in this instrument are defined in the Radiocommunications (Unacceptable Levels of Interference — 850/900 MHz Band) Determination 2021: (a) 850/900 MHz band; (b) centre frequency; (c) device boundary; (d) device boundary criterion; (e) fixed receiver; and (f) geographic area. (3) Unless the contrary intention appears, terms used in this instrument that are defined in: (a) the Radiocommunications (Interpretation) Determination 2015; or (b) if another instrument replaces that determination – that other instrument; have the same meaning as in that determination or instrument. Note: The following terms that are used in this instrument are defined in Schedule 1 to the Radiocommunications (Interpretation) Determination 2015: (a) land mobile service; and (b) spurious emission. (4) In this instrument, unless otherwise specified, a reference to part of the spectrum or a frequency band includes all frequencies that are greater than but not including the lower frequency, up to and including the higher frequency.
