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

4 Definitions (1) In this instrument, unless the contrary intention appears: Canberra Deep Space Communications Complex means the earth station receiver operating in the frequency range 25.5 GHz–27 GHz and located at -35.398335˚N, 148.981942˚E. fixed service has the same meaning as in the spectrum plan. harmful interference has the meaning given in the spectrum plan. in-band means: (a) for a radiocommunications transmitter or radiocommunications receiver operated under a spectrum licence, the frequencies within the frequency band in which operation of those radiocommunications devices is authorised under the licence; and (b) for a radiocommunications transmitter or radiocommunications receiver operating under an apparatus licence, the frequencies within the lower frequency limit and the upper frequency limit specified in the licence. indoor transmitter means a radiocommunications transmitter that: (a) is in an enclosed space; and (b) has, at every point that is 2 metres from the outside surface of the enclosed space, a power flux density that: (i) if the transmitter transmits in the frequency range 27 GHz–27.5 GHz and is located inside an inner-footprint area – is less than or equal to -9 dBW/m2 per occupied bandwidth; (ii) in any other case – is less than or equal to -7 dBW/m2 per occupied bandwidth. inner-footprint area means an area described in Schedule 1. inter-satellite service has the same meaning as in the spectrum plan.
