SIST EN 302 408 V7.1.1:2003 is the SIST adoption of ETSI EN 302 408 Version 7.1.1 for the GSM Cordless Telephony System (CTS), Phase 1, CTS-FP Radio subsystem. It specifies the radio requirements for the CTS-Fixed Part (CTS-FP) transceiver and the radio subsystem frequency control used in CTS-FP equipment operating in GSM 900 MHz and 1800 MHz bands. In practice, it is the document used to design, test, and assess CTS-FP radio performance and frequency-selection behavior.
What does SIST EN 302 408 V7.1.1:2003 specify?
SIST EN 302 408 V7.1.1:2003 defines the radio performance and frequency-control requirements for the CTS-FP. Clause 1 states that the requirements apply across the full environmental range defined for CTS-FP equipment, with Annex C providing those conditions.
The document is organized into five clauses and four annexes:
- Clause 1 - Scope
- Clause 2 - References
- Clause 3 - Definitions and abbreviations
- Clause 4 - Radio transmission and reception
- Clause 5 - Radio subsystem frequency control
| Annex | What it covers |
|---|---|
| Annex A | Spectrum characteristics due to modulation |
| Annex B | Transmitted power level versus time |
| Annex C | Environmental conditions |
| Annex D | Change control history |
What are the key requirements of SIST EN 302 408 V7.1.1:2003?
Clause 4 defines the core RF behavior that CTS-FP equipment has to meet in GSM900 and DCS1800 operation. The practical effect is that a supplier can check transmit power, spectrum purity, receiver robustness, and link performance against one CTS-FP standard.
Operating bands and channel plan
Clause 4.1 sets the operating bands for P-GSM, E-GSM, and DCS1800, with 200 kHz carrier spacing and ARFCN-based channel designation. For the reader, this fixes where the CTS-FP may transmit and receive and how channels are identified.
Transmit power and power control
Clause 4.3.1 gives the maximum and lowest nominal output power, plus the power-control levels for GSM900 and DCS1800. It also states how output power steps relate from one control level to the next. In practice, this is what a designer uses to set RF gain control and what a test lab uses to verify the actual burst power.
Output spectrum, switching transients, and spurious emissions
Clause 4.3.2 limits the RF spectrum due to modulation and switching transients, with Annex A showing the modulation spectrum. Clause 4.3.3 sets spurious-emission limits and the measurement bandwidths used at different offsets. This matters because it tells manufacturers how much unwanted RF energy may appear around and outside the transmit band.
Burst timing and residual output between bursts
Clause 4.3.5 and Annex B define the transmitted power level versus time and the residual power allowed between active bursts. This is important for burst-shaped GSM signals because it checks that power ramps and idle periods stay within the permitted mask.
Receiver immunity and sensitivity
Clause 4.4 covers blocking, AM suppression, and intermodulation, while Clause 4.5 covers nominal error rate, reference sensitivity, reference interference, erroneous frame indication, access performance, and frequency-hopping performance under interference. For users, this is the evidence that the CTS-FP can still receive usable service when unwanted signals, fading, or hopping are present.
Radio subsystem frequency control
Clause 5 requires CTS-FP procedures for Adaptive Frequency Allocation (AFA), Total Frequency Hopping (TFH) carrier list selection, CTSBeacon channel carrier selection, and timeslot assignment for dedicated connection. Table 3 defines the control parameters. In practice, this is the logic that helps the CTS-FP choose cleaner carriers and assign traffic more effectively.
What terms does SIST EN 302 408 V7.1.1:2003 define?
- CTS Mobile Station (CTS-MS) - a GSM-MS that supports CTS.
- CTS Fixed Part (CTS-FP) - the device that links the CTS-MS to the fixed network.
- GSM-CTS - the Cordless Telephony System based on GSM.
- Adaptive Frequency Allocation (AFA) - the CTS-FP function that orders carriers using interference information reported by the CTS-MS.
- Generic Frequency List (GFL) - the list of carriers allowed for CTS-FP and CTS-MS operation.
- Total Frequency Hopping (TFH) - the hopping scheme that uses a selected carrier list for transmission and reception.
- CTSBeacon channel carrier - the carrier chosen from the TFH list for CTSBCH downlink and other specified channels.
Who uses SIST EN 302 408 V7.1.1:2003?
Manufacturers of CTS-FP equipment use it to design RF sections, power control, spectrum masks, and frequency-selection behavior. Test laboratories use it to measure transmit power, emissions, receiver performance, and environmental behavior in a repeatable way. Quality and procurement teams use it to check whether a CTS-FP claim matches the GSM900 or DCS1800 requirements defined here.
What changed in SIST EN 302 408 V7.1.1:2003 from the previous edition?
Annex D records change control items for environmental conditions, clarification of AFA and TFH selection performance, and modification of receiver performance for CTSARCH. The history also shows a version update from 7.1.0 to 7.1.1 for publication.
Which standards are used with SIST EN 302 408 V7.1.1:2003?
- GSM01.04 - gives the abbreviations and acronyms used in the document.
- GSM03.22 - covers MS idle mode and group receive mode.
- GSM03.52 - defines the lower layers of the CTS radio interface, Stage 2.
- GSM04.56 - gives the CTS radio interface layer 3 specification.
- GSM05.01 - defines the physical-layer reference configuration used for CTS-FP radio tests.
- GSM05.05 - provides general RF transmission and reception rules, including phase accuracy and propagation references.
- GSM05.08 - provides radio subsystem link control and the AFA monitoring procedure.
- GSM05.10 - defines radiofrequency tolerance and burst timing.
- GSM11.56 - gives the CTS-FP conformance specification and the measurement methods used for these RF tests.
- GSM03.56 - provides the CTS architecture description used by the frequency-control clauses.
What does the SIST EN 302 408 V7.1.1:2003 document contain?
The document contains transmitter tables for output power and power-control levels, receiver tables for blocking, AM suppression, and intermodulation, and performance tables for sensitivity and interference. It also contains the measurement and limit descriptions for modulation spectrum, switching transients, and spurious emissions, plus the timing mask in Annex B.
It includes the frequency-control procedure for AFA and TFH, the parameter table for GFL, AFA_USE, SEL_RANGE, APPROACH_TYPE, MIN_NB_FREQ, FWT_SIZE_WIN, SWT_SIZE_WIN, INTERF_THRESHOLD, and CTSBCH_SEL_MODE, and an example scenario showing carrier selection. Annex C gives the environmental temperature and voltage conditions, and Annex D records the change history.
