Frequency assignment requirements for the land mobile service are detailed in Radiocommunications Assignment Licensing Instruction (RALI) LM8. The RALI provides frequency assignment policy and coordination procedures for single and two frequency land mobile systems employing angle and digital modulation methods.
The RALI has been developed primarily for ACMA and accredited frequency assigners. It is also a useful guide for land mobile system planners. The RALI is based on relevant ITU-R work, the Australian experience in this field, and other studies conducted by the ACMA and its predecessors.
The RALI currently applies to angle and digital modulated:
- single and two frequency systems in the VHF Mid (70-87.5 MHz) and VHF High (148-174 MHz) bands using 12.5 kHz channelling
- single and two frequency systems in the 400 MHz band using 12.5 and 25 kHz channelling and
- 800 MHz trunked systems using 25 kHz channelling.
