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

3 Authority This instrument is made under subsection 145(4) of the Act.

4 Repeal of the Radiocommunications (Unacceptable Levels of Interference – 700 MHz Band) Determination 2012 The Radiocommunications (Unacceptable Levels of Interference — 700 MHz Band) Determination 2012 [F2012L02543] is repealed.

5 Definitions (1) In this instrument, unless the contrary intention appears: 700 MHz band means the 700 MHz lower band and the 700 MHz upper band. 700 MHz lower band means the frequency band 703 MHz to 748 MHz. 700 MHz band spectrum licence means a spectrum licence that authorises the operation of radiocommunications devices in the 700 MHz band. 700 MHz upper band means the frequency band 758 MHz to 803 MHz. AAS means a base station antenna system where the amplitude and/or phase between antenna elements is continually adjusted, resulting in an antenna pattern that varies in response to short term changes in the radio environment. Note: AAS stands for active antenna system. Act means the Radiocommunications Act 1992. Australian Spectrum Map Grid means the Australian Spectrum Map Grid 2012, published by the ACMA. Note: The Australian Spectrum Map Grid is available, free of charge, from the ACMA's website at www.acma.gov.au. Australian territorial sea baseline means the baseline from which the breadth of the territorial sea, or any part of the territorial sea, is to be measured under section 7 of the Seas and Submerged Lands Act 1973. beam-forming means use of an AAS to electrically steer antenna beams. 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. DEM-3S means the dataset: (a) with the citation "Gallant, J., Wilson, N., Tickle, P.K., Dowling, T., Read A. 2009. 3 Second SRTM Derived Digital Elevation Model (DEM) Version 1.0. Record 1.0. Geoscience Australia, Canberra"; and (b) given the persistent identifier http://pid.geoscience.gov.au/dataset/ga/69888; published by Geoscience Australia. Note: DEM-3S is available, free of charge, from Geoscience Australia using the persistent identifier. More information about DEM-3S is available, free of charge, from the Geoscience Australia website at www.ga.gov.au. DEM-3S cell means an individual height element of the DEM-3S. device boundary: see item 1 of Schedule 2. device boundary criterion: see item 2 of Schedule 2. effective antenna height: see Schedule 3. EIRP, in relation to a radiocommunications device, means the equivalent isotropically radiated power of the device. emission designator: see section 7. 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. GDA94 means the geodetic datum designated as the "Geocentric Datum of Australia (GDA)" gazetted in the Commonwealth of Australia Gazette No. GN 35 on 6 September 1995, as existing on that date. Note: Gazette No. GN 35 is available, free of charge, from the Federal Register of Legislation at www.legislation.gov.au. geographic area, for a spectrum licence, means the area within which the operation of a radiocommunications device is authorised under the licence. group of radiocommunications receivers: see section 9. group of radiocommunications transmitters: see section 8. HCIS means the cell grouping hierarchy scheme used to describe areas in the Australian Spectrum Map Grid. Note: HCIS stands for hierarchical cell identification scheme. HCIS identifier means an identifier used to describe a geographical area in the HCIS. horizontally radiated power, for a radiocommunications device, means the sum of: (a) the maximum true mean power, in dBm per specified rectangular bandwidth, at the antenna connector, that is located within the frequency band of the spectrum licence authorising the operation of the radiocommunications device; and (b) the antenna gain relative to an isotropic antenna in a specified direction in the horizontal plane containing the phase centre of the antenna used with the radiocommunications device, in dBi. location: see Schedule 1. maximum true mean power means the true mean power measured in a specified rectangular bandwidth that is located within a specified frequency band, such that the true mean power is the maximum of true mean powers produced. Note: The power within the specified rectangular bandwidth is normally established by taking measurements using either an adjacent channel power meter or a spectrum analyser. Estimation of the accuracy of the measuring equipment, measurement protocols and any adjustments made to measurements to take account of practical filter shape factors should be in accordance with good engineering practices. mean power means the average power measured during an interval of time that is at least 10 times the period of the lowest modulation frequency. occupied bandwidth, in relation to a radiocommunications transmitter, means the width of a frequency band having upper and lower limits that contain 99% of the true mean power of the transmitter's emission at any time. Radio Regulations means the document titled 'Radio Regulations', published by the International Telecommunication Union. Note 1: The Radio Regulations are not regulations made by the Governor‑General under the Act. Note 2: The Radio Regulations are available, free of charge, from the International Telecommunication Union's website at www.itu.int. total radiated power, in relation to a radiocommunications transmitter, means the integral of the power transmitted in different directions over the entire radiation sphere. It is measured considering the combination of all radiating elements on an antenna panel or individual device. true mean power means: (a) if an unmodulated carrier is present – the mean power measured while the unmodulated carrier is present; and (b) if an unmodulated carrier is not present – the mean power measured while transmitted information is present. Note: A number of other expressions used in this instrument are defined in the Act, including the following: (a) ACMA; (b) core condition; (c) frequency band; (d) interference; (e) radiocommunications device; (f) radiocommunications receiver; (g) radiocommunications transmitter; (h) radio emission; (i) Register; (j) spectrum licence. (2) In this instrument, unless otherwise specified, a reference to a part of the spectrum, a frequency band or a frequency range 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, a frequency band or a frequency range is not included in the part of the spectrum, the frequency band or the frequency range.
