Part 1—Preliminary

1 Name These are the Radiocommunications Advisory Guidelines (Managing Interference to Spectrum Licensed Receivers – 1800 MHz Band) 2023.

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

4 Repeal of other guidelines (1) The Radiocommunications Advisory Guidelines (Managing Interference to Spectrum Licensed Receivers – 1800 MHz Band) 2012 [F2012L02047] are repealed. (2) The Radiocommunications Advisory Guidelines (Additional Device Boundary Criteria – 1800 MHz Lower Band) 2012 [F2012L02046] are repealed.

5 Definitions (1) In this instrument: 1800 MHz band means the 1800 MHz lower band and the 1800 MHz upper band. 1800 MHz lower band means the frequency band 1710 MHz to 1785 MHz. 1800 MHz receiver means a radiocommunications receiver operated under an 1800 MHz spectrum licence. 1800 MHz spectrum licence means a spectrum licence that authorises the operation of radiocommunications devices in the 1800 MHz band. 1800 MHz upper band means the frequency band 1805 MHz to 1880 MHz. Act means the Radiocommunications Act 1992. adjacent channel, in relation to another channel (the occupied 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: see item 2 of Schedule 1. centre frequency, in relation to a radiocommunications transmitter, means the frequency midway between the lower and upper frequency limits of the transmitter's occupied bandwidth. compatibility requirement: see Part 5 and Schedule 2. 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 areas and frequencies of the licence. fixed receiver means a radiocommunications receiver: (a) located at a fixed point on land or sea; and (b) not designed or intended for use while in motion. fixed transmitter means a radiocommunications transmitter: (a) located at a fixed point on land or sea; and (b) not designed or intended for use while in motion. frequency adjacent spectrum licence, in relation to a spectrum licence (the first licence), means a spectrum licence that authorises the operation of radiocommunications devices in a part of the spectrum that is adjacent to the parts of the spectrum specified in a core condition of the first licence. geographic area, for a spectrum licence, means the area within which operation of a radiocommunications device is authorised under the licence. in-band means: (a) for a radiocommunications device operated under a spectrum licence – the part of the spectrum within which the operation of radiocommunications devices is authorised under the licence; or (b) for a radiocommunications device operated under an apparatus licence that specifies a frequency band – the frequencies within the lower frequency limit and the upper frequency limit specified in the licence; (c) for a radiocommunications device operated under an apparatus licence that specifies a specific frequency and bandwidth – the frequencies within that bandwidth, when centred on the specific frequency. intermodulation response rejection: see item 3 of Schedule 1. mobile device means a radiocommunications device that is used: (a) while it is in motion on land, on water or in the air; or (b) in a stationary position at unspecified points on land, on water or in the air. notional receiver performance level: see subsection 12(2). out-of-band, for a radiocommunications device, means a frequency other than an in-band frequency. receiver blocking, in relation to a radiocommunications receiver, means the measure of the ability of the receiver to receive a wanted signal in the presence of a high level unwanted interferer on frequencies other than those of an adjacent channel. section 145 determination means the Radiocommunications (Unacceptable Levels of Interference – 1800 MHz Band) Determination 2023. Note: The section 145 determination is available, free of charge, from the Federal Register of Legislation at www.legislation.gov.au. spectrum space means the three dimensional space consisting of a frequency band and a geographic area. spurious response immunity: see item 5 of Schedule 1. unwanted signal means a radio emission from a radiocommunications transmitter that is not a wanted signal. wanted signal means a radio emission from a radiocommunications transmitter that is intended for reception by a radiocommunications receiver 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) radio emission; (k) spectrum licence. (2) In this instrument, unless the contrary intention appears, each term listed in subsection (3) has the meaning given by: (a) the section 145 determination; or (b) if another instrument replaces that determination – the other instrument. (3) For the purposes of subsection (2), the terms are: (a) additional device boundary criterion; (b) areas of high mobile use; (c) device boundary; (d) device boundary criterion; (e) effective antenna height; (f) high sited; (g) low sited. (4) In this instrument, unless otherwise specified, a reference to a 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. Note: This subsection means the lower number in a part of the spectrum or a frequency band is not included in the part of the spectrum or the frequency band.
