5 Definitions

(1) In this instrument:

850/900 MHz band means the following frequency bands:

(a) 850 MHz Lower Sub-band;
(b) 850 MHz Upper Sub-band;
(c) 900 MHz Lower Sub-band; and
(d) 900 MHz Upper Sub-band.

850 MHz Lower Sub-band means the frequency band 814 MHz to 845 MHz.

850 MHz Upper Sub-band means the frequency band 859 MHz to 890 MHz.

900 MHz Lower Sub-band means the frequency band 890 MHz to 915 MHz.

900 MHz Upper Sub-band means the frequency band 935 MHz to 960 MHz.

Act means the Radiocommunications Act 1992.

active antenna system or 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.

ASMG means the Australian Spectrum Map Grid 2012, published by the ACMA on its website at www.acma.gov.au.

Note: The ASMG can be accessed, free of charge, on the ACMA’s website: www.acma.gov.au.

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 69888;

containing modelled terrain height information for Australia, published by Geoscience Australia.

Note: Copies of DEM-3S can be obtained, free of charge, from the Geoscience Australia website: www.ga.gov.au.

DEM-3S cell means an individual height element of the DEM-3S.

device boundary, in relation to a radiocommunications transmitter or a group of radiocommunications transmitters operated under a spectrum licence, means the device boundary established in accordance with Part 1 of Schedule 2.
