RALI LM8 - Frequency Assignment Requirements for the Land Mobile Servce

Radiocommunications Assignment and Licensing Instruction (RALI) LM08 “Frequency Assignment Requirements for the Land Mobile Service” - available in Word (287KB) or PDF (456KB) formats. For ease of reference, the frequency-distance constraints of Annex C are consolidated in this excel workbook. Also included are calculated frequency-distance values before a number of simplifications were made as a result of consultation on IFC 42/2014.

Background

RALI LM08 “Frequency Assignment Requirements for the Land Mobile Service” 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 systems in the VHF Mid Band (70-87.5 MHz), VHF High Band (148-174 MHz) and 400 MHz band using 6.25 kHz, 12.5 kHz and 25 kHz channel bandwidths. It covers both high power (LMRS) and low power (LPMRS) systems, and both single frequency and two frequency systems. The RALI also covers 800 MHz trunked systems using 25 kHz channels.

RALI LM8 was last updated on 11 July 2016 to facilitate harmonised government spectrum area licensing.
