SIST EN 300 910 V6.7.1:2003 is the Slovenian adoption of ETSI EN 300 910 for GSM Phase 2+ radio transmission and reception. It defines RF requirements for mobile stations, base station systems, repeaters and antenna feeder loss compensators in the GSM900 and DCS1800 bands, so manufacturers, test labs and network engineers know what to design, measure and document.
What does SIST EN 300 910 V6.7.1:2003 specify?
SIST EN 300 910 V6.7.1:2003 specifies the radio-frequency behavior of GSM equipment in the 900 MHz and 1800 MHz bands. It covers compatibility between radio channels and the transmission quality of the system, with separate treatment for Mobile Station (MS), Base Station System (BSS), repeaters and Antenna Feeder Loss Compensator (AFLC) devices.
The document is organized into clauses for scope, band and channel arrangement, reference configuration, transmitter characteristics, receiver characteristics, and transmitter/receiver performance. Annexes A-F give spectrum plots, timing masks, propagation models, environmental conditions and hardware-specific requirements, while Annex G records change requests.
| Annex | What it covers |
|---|---|
| A | Spectrum characteristics due to modulation |
| B | Transmitted power level versus time |
| C | Propagation conditions and channel models |
| D | Environmental conditions |
| E | Repeater characteristics |
| F | AFLC characteristics |
| G | Change request history |
What are the key requirements of SIST EN 300 910 V6.7.1:2003?
SIST EN 300 910 V6.7.1:2003 sets the main RF limits and test conditions for GSM900 and DCS1800 equipment. The most important points are the band plan, output power, spectrum masks, spurious emissions, receiver immunity and performance under fading and interference.
Band plan and reference setup
Clause 2 defines the operating bands for P-GSM, E-GSM, R-GSM and DCS1800, using 200 kHz carrier spacing and ARFCN channel numbering. In practice, this fixes where equipment may transmit and receive, and how each channel is identified.
Clause 3 ties the RF requirements to the GSM05.01 reference configuration and distinguishes micro-BTS from a normal BTS. This matters because micro-BTS equipment is assessed with different range and close-proximity expectations.
Transmit power and burst behavior
Clause 4.1 defines MS power classes, BTS power classes and allowed power-control steps. It also states that multiband MSs must meet the requirements of every band they support, and that BTSs need adjustable output power in steps for coverage planning.
Clause 4.5 controls how power rises and falls in time during a burst and between bursts. In practice, this limits unwanted emissions when a transmitter switches on and off, especially in multislots or discontinuous transmission.
Spectrum, spurious emissions and phase accuracy
Clause 4.2 separates emissions caused by modulation from those caused by switching transients, with Annex A showing the modulation spectrum and Annex B giving the time mask. Clause 4.3 sets spurious-emission limits for conducted and radiated cases, including limits in the receive band.
Clause 4.6 limits phase error during a burst. That matters for demodulation quality and for keeping the transmitted GSM waveform close to the theoretical modulation.
Receiver immunity and end-to-end performance
Clause 5 covers blocking, AM suppression, intermodulation and receiver spurious emissions. Clause 6 then checks actual communication performance using nominal error rates, reference sensitivity, reference interference ratios, paging and random-access behavior, and frequency-hopping tests under interference.
Annex C supplies the propagation models used in those tests, including static, TU, RA, HT and equalization cases. This is important because pass/fail results depend on the channel model, not just the signal level.
What terms does SIST EN 300 910 V6.7.1:2003 define?
- Mobile Station (MS) - the user equipment whose transmitter and receiver are tested in the document.
- Base Station System (BSS) - the network-side radio equipment, including BTS and micro-BTS, that serves the mobile.
- Base Transceiver Station (BTS) - the radio unit in the BSS for normal base-station operation.
- micro-BTS - a BTS with reduced range requirements and stricter close-proximity behavior.
- absolute radio frequency channel number (ARFCN) - the channel number used to identify a 200 kHz carrier.
- Antenna Feeder Loss Compensator (AFLC) - a vehicle-mounted device that offsets feeder loss between the MS and antenna.
- slow frequency hopping (SFH) - a mode where the radio changes carrier frequencies during operation.
Who uses SIST EN 300 910 V6.7.1:2003?
SIST EN 300 910 V6.7.1:2003 is used by GSM equipment manufacturers, radio design engineers, conformance test labs, network operators and quality teams. They use it to design transmitters and receivers, set power classes, verify sensitivity and interference performance, and plan tests for repeaters and AFLCs.
What changed in SIST EN 300 910 V6.7.1:2003 from the previous edition?
SIST EN 300 910 V6.7.1:2003 is published as version 6.7.1, and the change history shows a version update from 6.7.0 to 6.7.1 for publication. Annex G also records earlier change requests that introduced items such as GPRS reference performance, repeater systems using frequency shift, power-control and sensitivity updates, and the frequency-hopping performance requirement under interference.
Which standards are used with SIST EN 300 910 V6.7.1:2003?

- GSM02.06 - defines types of MS, including multiband MSs and the small MS context.
- GSM03.64 - gives the GPRS radio interface stage 2 reference.

- GSM05.04 - gives the theoretical modulation waveform used for phase-accuracy checks.
- GSM05.08 - supports adaptive power control and link-control requirements.
- GSM05.10 - provides radio-frequency tolerance and burst-timing related requirements.
- GSM11.10 and GSM11.20 - specify the measurement methods used for conformance testing.
- GSM04.14 - defines the loopback facility used in receiver performance assessment.
- GSM11.11 - is listed as a related GSM interface specification.
- ITU-T O.153 - provides the pseudo-random sequence basis for error-performance testing.
