Radiocommunications Advisory Guidelines (Managing Interference to Spectrum Licensed Receivers — 3.4 GHz Band) 2015
Radiocommunications Act 1992

made under section 262 of the
Radiocommunications Act 1992.

Compilation No. 2

Compilation date:    27 June 2023

Includes amendments up to: F2023L00856

Prepared by the Australian Communications and Media Authority, Melbourne.

Part 1 Introduction

1.1  Name of Advisory Guidelines

      These guidelines are the Radiocommunications Advisory Guidelines (Managing Interference to Spectrum Licensed Receivers — 3.4 GHz Band) 2015.

   1.3  Purpose

      (1) The purpose of these guidelines is to:

         (a) manage in-band and out-of-band interference by providing compatibility requirements for registered fixed receivers operating under spectrum licences issued for the 3.4 GHz band; and

         (b) provide protection to radiocommunications receivers operating under spectrum licences issued for the 3.4 GHz band from interference caused by radiocommunications transmitters operating under a class licence, and from fixed transmitters operating under an apparatus licence or a spectrum licence.

      (2) These guidelines should be used by operators of spectrum licensed services, class licensed services and apparatus licensed services in the planning of services or in the resolution of an interference case.

      (3) The ACMA will take these guidelines into account in determining whether interference has occurred to a radiocommunications receiver operating under a 3.4 GHz band spectrum licence from a transmitter operating under another licence, in the absence of separate criteria agreed between affected licensees.
      (4) These guidelines do not prevent a licensee negotiating other protection requirements with another licensee.

   1.4  Interpretation

      (1) In these guidelines, unless the contrary intention appears:
      3.4 GHz band means the part of the spectrum from 3400 MHz to 3800 MHz.

      Act means the Radiocommunications Act 1992.

      adjacent channel means a channel with a centre frequency offset on either side of the assigned channel frequency of the occupied channel by a specific frequency relation.

      adjacent channel selectivity means a measure of the ability of the radiocommunications receiver to receive a wanted signal without exceeding a specified degradation in output quality due to the presence of an unwanted adjacent channel signal.

      emission buffer zone means a zone along the frequency or geographic boundary of a spectrum licence where emission levels of radiocommunications transmitters are reduced to ensure that significant levels of emissions stay within the geographic area and frequency band of the licence.

      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.

      intermodulation response rejection means a measure of the ability of
