SIST ETS 300 609-4 E4:2003 is the Slovene adoption of ETS 300 609-4, published by SIST from ETSI. It specifies radio frequency tests for GSM 900 and DCS 1800 repeaters in the GSM Base Station System (BSS), including repeaters with frequency shift functions, so manufacturers, test laboratories, and approval teams can verify how the equipment behaves in and around the operating band.
What does SIST ETS 300 609-4 E4:2003 specify?
SIST ETS 300 609-4 E4:2003 specifies RF test methods and conformance limits for GSM repeaters that receive, amplify, and retransmit both Mobile Station (MS) and Base Transceiver Station (BTS) signals. It is organized into scope, normative references, definitions and abbreviations, general provisions, five main test clauses, and two informative annexes.
The standard covers repeaters for GSM Phase 2 and GSM Phase 2+. It focuses on the repeater as RF equipment, so the practical outcome is a set of agreed measurements for emissions, gain, frequency error, and phase error.
| Annex | What it covers |
|---|---|
| Annex A | Informative method for testing gain outside the operating band for part-band repeaters |
| Annex B | Informative change history |
What are the key requirements of SIST ETS 300 609-4 E4:2003?
SIST ETS 300 609-4 E4:2003 asks the manufacturer to declare the operating band or bands, the maximum rated output power per channel, and the number of supported channels. In practice, these declarations define how the repeater is configured for testing and what output level the measurements must reference.
Clause 4 also requires measurement methods and measurement uncertainty to follow ETR 027 and ETR 028, unless this standard says otherwise. That matters because the reported results must be comparable and traceable across test labs.
Emissions and gain limits
Clause 5 measures spurious emissions at antenna ports and as radiated emissions from the cabinet and structure. The repeater is set to maximum gain, tested with and without an RF input signal, and the radiated measurements use an ETS 300 113 test site. The result tells a buyer or assessor whether unwanted emissions stay within the stated limits.
Clause 6 checks intermodulation attenuation using two continuous RF signals spaced by the minimum network spacing of 600 kHz. This is a practical way to see whether non-linear behavior creates harmful products when the repeater is driven near its declared maximum output power.
Clause 7 measures out of band gain and harmonic response. The test sweeps offsets from the band edges and harmonic frequencies up to 12.75 GHz, which helps confirm that the repeater does not amplify signals where it should not.
Frequency-shift repeater system checks
Clause 8 applies only to repeater systems using frequency shift and measures frequency error. The system is levelled per the manufacturer’s guidance, synchronized with an accurate frequency source, and tested at the lowest and highest ARFCN supported by the system. This verifies that the shifted signal stays accurately placed on frequency in service.
Clause 9 also applies only to frequency-shift systems and measures phase error. The test uses a continuous synchronized GMSK signal with a pseudo random bit sequence and evaluates phase trajectory at the output. This matters because phase accuracy affects whether the repeater preserves the transmitted signal shape well enough for GSM operation.
What terms does SIST ETS 300 609-4 E4:2003 define?
Broadband repeater - A repeater designed to operate on any combination of ARFCNs within its operating band, up to a stated maximum number.
Channelized repeater - A repeater designed for a specified subset of ARFCNs, either fixed during manufacture or programmable.
Repeater system using frequency shift - A system with a master unit near the BTS and at least one remote unit near the coverage area, where channels are shifted and then shifted back.
Repeater - A bi-directional RF amplifier that retransmits both MS and BTS signals in their respective GSM transmit bands.
Spurious emissions - Unwanted emissions at frequencies other than the carrier and its normal sidebands.
BTS / MS / RF - BTS means Base Transceiver Station, MS means Mobile Station, and RF means Radio Frequency.
Who uses SIST ETS 300 609-4 E4:2003?
Manufacturers use SIST ETS 300 609-4 E4:2003 to define product declarations and design verification tests for GSM repeaters. Test laboratories use it to set up repeatable RF measurements and to report results in a standard way.
Quality managers, approval engineers, and regulatory teams use it to check conformance for emissions, gain, and signal integrity. It is also relevant where operators coordinate repeater use across GSM 900 or DCS 1800 bands, especially for part-band or frequency-shift deployments.
What changed in SIST ETS 300 609-4 E4:2003 from the previous edition?
The change history shows that version 5.2.1 is a publication update of the Fourth Edition. The revision trail also records the addition of references to ETR 027 and ETR 028, together with earlier technical updates such as part-band repeater testing, intermodulation attenuation, the R-GSM band, and frequency-shift repeater clauses.
Which standards are used with SIST ETS 300 609-4 E4:2003?
ETR 350 (GSM 01.04) supplies abbreviations and acronyms used across GSM specifications.
ETS 300 019-1-0, ETS 300 019-1-3, ETS 300 019-1-4, and IEC 721 provide environmental condition classifications for the declared test environment.
ETS 300 113 defines the radiated test site conditions used for spurious emission measurements.
ETS 300 910 (GSM 05.05) provides the radio transmission and reception reference limits, including the annex E references used throughout the test clauses.
IEC 68-2-1 and IEC 68-2-2 provide the procedures for low- and high-temperature testing.
ETS 300 607-1 (GSM 11.10-1) and ETS 300 609-1 (GSM 11.21) support the phase error calculation reference.
ETR 027 and ETR 028 provide the measurement methods and uncertainty treatment used by this standard.
What does the SIST ETS 300 609-4 E4:2003 document contain?
The document contains the RF test framework for GSM repeaters, including the operating bands, test environments, manufacturer declarations, and the detailed setup for each measurement. It gives procedures for spurious emissions, intermodulation attenuation, out of band gain, frequency error, and phase error.
It also includes tables for the MS and BTS transmit bands, normal environmental limits, and measurement bandwidths for spurious emissions. Annex A gives an informative method for part-band repeater gain testing, and Annex B records the change history.
