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 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 an area in the HCIS.
high sited: see subsection (2).
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.
ITU-R Recommendation means a recommendation made by the Radiocommunication Sector of the International Telecommunication Union.

            Note: ITU-R Recommendations are available, free of charge, from the website of the International Telecommunication Union at www.itu.int.
location: see Schedule 1.
low sited: see subsection (3).
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 the 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, the measurement protocol and any adjustments made to measurements to take account of practical filter shape factors should be in accordance with good engineering practice.
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
