SIST EN 300 910 V6.5.1:2003 is the Slovenian adoption of ETSI EN 300 910 Version 6.5.1 for GSM Phase 2+ radio transmission and reception. It specifies RF requirements for Mobile Station (MS), Base Station System (BSS), repeater and Antenna Feeder Loss Compensator (AFLC) equipment used in GSM900 and DCS1800 networks. Engineers use it to check output power, spectrum, receiver performance and burst behavior against the GSM radio interface requirements.

What does SIST EN 300 910 V6.5.1:2003 specify?

SIST EN 300 910 V6.5.1:2003 defines the radio-frequency requirements for GSM transceivers in the 900 MHz and 1800 MHz bands. The document focuses on compatibility between radio channels and on transmission quality, with detailed measurement methods referenced to GSM11.10 and GSM11.20.

The standard is organized into the front matter, six main clauses, and seven annexes. Clause 2 sets the band plan and channel numbering, Clause 3 gives the reference configuration, Clause 4 covers transmitter characteristics, Clause 5 covers receiver characteristics, and Clause 6 covers combined transmitter/receiver performance.

Annex	What it covers
A	Informative spectrum characteristics for modulation
B	Normative transmitted power level versus time
C	Normative propagation conditions and channel models
D	Normative environmental conditions
E	Normative repeater characteristics
F	Normative AFLC characteristics
G	Informative change request history

What are the key requirements of SIST EN 300 910 V6.5.1:2003?

Clause 2 defines the supported frequency bands - P-GSM, E-GSM, R-GSM and DCS1800 - and uses 200 kHz carrier spacing with ARFCN-based channel numbering. In practice, this tells designers and operators how carriers are placed and which band combinations a multiband terminal must support.

Clause 4.1 sets class-based output power behavior for MS, BTS and micro-BTS equipment. The same clause also defines stepped power control, which matters because the network must be able to command transmit power changes without stepping outside the allowed class behavior.

Clause 4.2 and Annex A define the transmitted RF spectrum. The standard separates the effect of modulation from switching transients, so test houses can check both the steady spectrum and the burst edges that create adjacent-channel interference.

Clause 4.3 limits spurious emissions from MS, BTS and repeaters, including emissions into nearby receive bands. This matters in mixed networks because unwanted signals can desensitize the same equipment or nearby systems.

Clause 4.5 and Annex B define how transmitted power must change over time during bursts. For the reader, this is the part that controls ramp-up, ramp-down and residual power between active timeslots.

Clause 4.6 sets burst phase accuracy against the theoretical GSM modulation. In practice, this is the modulation-quality check that protects demodulation performance and helps keep error rates under control.

Clause 4.7 sets intermodulation attenuation requirements for BTS, MS and mobile PBX cases. This is important when several carriers are present or when a strong external signal reaches the transmitter path.

Clauses 5 and 6 define receiver blocking, AM suppression, intermodulation and spurious-emission behavior, then link those receiver limits to performance tests. Clause 6 also covers Nominal Error Rates (NER), reference sensitivity, reference interference, erroneous frame indication, high-input-level random access and paging tests, and frequency hopping under interference conditions.

What terms does SIST EN 300 910 V6.5.1:2003 define?

• Mobile Station (MS) - the user terminal whose transmitter and receiver limits are specified in the standard.
• Base Station System (BSS) - the network-side radio subsystem that contains BTS or micro-BTS equipment.
• Base Transceiver Station (BTS) - the base radio unit whose transmit and receive characteristics are specified.
• micro-BTS - a smaller BTS variant with reduced range requirements and tighter close-proximity behavior.
• Absolute Radio Frequency Channel Number (ARFCN) - the number used to identify a carrier frequency in the GSM channel plan.
• Discontinuous Transmission (DTx) - operation where a transmitter does not send bursts in unused timeslots.
• Antenna Feeder Loss Compensator (AFLC) - a vehicle-mounted unit that compensates feeder loss between an MS and the antenna.
• General Packet Radio Service (GPRS) - the packet-data mode whose channels and performance appear in Clause 6.

Who uses SIST EN 300 910 V6.5.1:2003?

SIST EN 300 910 V6.5.1:2003 is used by GSM equipment manufacturers, radio design engineers, conformance test laboratories, network operators, and quality or procurement teams. It supports product design, type approval, RF verification, and incoming equipment checks for GSM900, DCS1800 and multiband products.

It is also relevant for people working on repeaters and AFLC devices, because the annexes give the RF limits and environmental context for those installations. For buyers and technical reviewers, it shows which equipment classes, bands and test conditions a product must satisfy.

What changed in SIST EN 300 910 V6.5.1:2003 from the previous edition?

The change-request history attached to the standard records the technical update subjects carried through the 6.5.x line, including GPRS reference performance, 14.4 kbps Data Service, repeater systems using frequency shift, adjacent timeslot rejection, frequency hopping performance under interference, BTS output power, 11-bit PRACH, false USF detection, DCS1800 power control levels 29-31, DCS1800 MS sensitivity for GPRS, correction of the reference for the MS test loop, signal level for reference interference measurements in GPRS, and deletion of micro-BTS maximum output power per carrier values expressed in watts.

Which standards are used with SIST EN 300 910 V6.5.1:2003?

• GSM01.04 - provides the abbreviations and acronyms used in the document.
• GSM02.06 - defines the types of Mobile Stations and the related power-class context.
• GSM03.64 - supplies the GPRS radio interface stage 2 background used for packet-mode requirements.
• GSM05.01 - gives the radio subsystem reference configuration.
• GSM05.04 - defines GSM modulation used in phase and spectrum checks.
• GSM05.08 - defines radio subsystem link control, including power control behavior.
• GSM05.10 - defines radio subsystem synchronization and radio frequency tolerance.
• GSM11.10 and GSM11.20 - provide the measurement methods used for the RF conformance tests.
• GSM04.14 - provides the special conformance testing functions, including the MS loopback facility.
• ITU-T Recommendation O.153 - supports error-performance measurement definitions.
• ETS 300 019-1-3 and ETS 300 019-1-4 - provide the environmental condition classes for stationary equipment.
• GSM03.30 and GSM05.50 - are named in the text for repeater planning and spectrum-mask conversion support.

What does the SIST EN 300 910 V6.5.1:2003 document contain?

The document contains power-class tables, power-control level definitions, spectrum masks, receiver acceptance tables and performance tables for GSM900 and DCS1800 equipment. It also contains burst timing masks in Annex B and propagation profiles in Annex C for rural, hilly, urban and equalization cases.

Annex D sets the environmental temperature, voltage and vibration conditions for MS and BSS equipment. Annex E defines repeater limits for spurious emissions, intermodulation, out-of-band gain, frequency error and phase error, while Annex F defines AFLC transmit and receive performance, including gain, group delay, noise figure, VSWR and stability.

The annexes also supply practical test material for design validation and conformance testing. Annex A gives spectrum plots, and Annex G records the change-request history behind the release.
