Specifies minimum requirements for tansmitters and receivers for use of the radiofrequency spectrum in accordance with spectrum planning and with existing services.

This Standard provides radiofrequency requirements for digital radio equipment operating in land mobile and fixed services radiofrequency bands in the frequency range 29.7 MHz to 1 GHz with channel spacings up to 25 kHz. Categories of equipment within this range include(a) base, mobile, personal mobile and RF control stations operating in designated land mobile bands; and (b) fixed point-to-point and point-to-multipoint equipment operating in designated single channel fixed service bands. Emissions not covered by ITU Radio Regulations (edition 1982), Article 4 and Appendix 6 (AP6, part A for details and definition of the emission characteristics) are not within the scope of this Standard. Equipment operating in the land mobile services bands from 806 to 825 MHz and 851 to 870 MHz is not covered by the Standard. NOTE: For operation of land mobile equipment in these bands refer to the relevant authorities in Australia and New Zealand.
