46 - APPENDIX ZZ - VARIATIONS FOR AUSTRALIA

Specifies the radio frequency characteristics of short range radio equipment and inductive loop systems required for suitable operation in the Australian radiofrequency spectrum. These devices include alarms, identification systems, telecommand and telemetry and may have antenna connectors or integral antennas. It also includes test methods for verifying that suitability. An appendix includes those requirements specific to the Australian radiofrequency spectrum plan. This Standard is based on and has been reproduced from ETSI I-ETS 300 330.

This I-ETS is a general standard for the frequency band 9 kHz to 25 MHz for radio equipment and 9 kHz to 30 MHz for inductive loop systems, which may be superseded by specific standards covering specific applications.This I-ETS covers the minimum characteristics considered necessary in order to make the best use of the available frequencies.It does not necessarily include all the characteristics which may be required by a user, nor does it necessarily represent the optimum performance achievable.It applies to SRDs as follows:- inductive loop systems;- with an antenna connection and/or with an integral antenna;- for alarms, identification systems, telecommand, telemetry, etc., applications;- with or without speech.All types of modulation for radio devices are covered by this I-ETS.This I-ETS covers fixed stations, mobile stations and portable stations. If the system includes transponders, these will be measured together with the transmitter.Two types of measuring methods are defined in this I-ETS due to the varied nature of the types of equipment used in this band. One method measures the RF carrier current, the other measures the H-field.CEPT Recommendation TIR 01-04 [2], on Low Power Devices (LPDs) using an integral antenna, mentions in the frequency range 9 kHz to 25 MHz two frequency bands, 6,765 to 6,795 MHz and 13,553 to 13,567 MHz, with a field strength limit of 65 dBV/m measured at 30 m (which is equivalent to 42 dBA/m at 10 m).On non-harmonized parameters, national administrations may impose conditions on the type of modulation, channel/frequency separations, maximum transmitter output power/effective radiated power, equipment marking and the inclusion of an automatic transmitter shut-off facility, as a condition for the issue of an individual or general licence, or as a condition for use under licence exemption.Additional standards or specifications may be required for equipment such as that intended for connection to the Public Switched Telephone Network (PSTN).This I-ETS covers requirements for radiated emissions below 30 MHz.
