SIST EN 301 426:2001 is the Slovenian adoption of EN 301 426 Version 1.1.1 from ETSI. It covers low data rate Land Mobile satellite Earth Stations (LMES) operating in the 1.5/1.6 GHz bands and specifies the radio spectrum and control-and-monitoring requirements needed to show conformity with Article 3.2 of the R&TTE Directive.
The standard is aimed at manufacturers, applicants, test laboratories and conformity assessors who need a clear basis for design checks and type testing. In practice, it tells them what emissions and safety-related control functions the LMES must meet, and how those checks are tested.
What does SIST EN 301 426:2001 specify?
SIST EN 301 426:2001 specifies technical requirements for LMES radio equipment used in satellite networks for exchange or distribution of information between users. It covers vehicle-mounted and portable equipment, including ancillary equipment and terrestrial ports, when operated within the declared operational environmental profile.
The standard applies to LMES operating in these bands:
| Annex/Clause | What it covers |
|---|---|
| Clause 1 | Scope and frequency bands |
| Clause 2 | Normative references |
| Clause 3 | Definitions and abbreviations |
| Clause 4 | Technical requirements |
| Clause 5 | Compliance testing |
| Annex A | EN Requirements Table (EN-RT) |
The NCF is outside the scope of the standard, but the LMES control functions are designed to respond to it. The document also notes that other ENs may apply to essential requirements under other parts of Article 3.
What are the key requirements of SIST EN 301 426:2001?
Radio emissions outside and within the operating bands
SIST EN 301 426:2001 limits unwanted emissions both outside the operating bands and within them. That matters because the equipment must avoid harmful interference to other radio services while still operating in the assigned LMSS bands.
Outside the bands, the standard sets limits for emissions from 30 MHz to 1000 MHz and for EIRP above 1000 MHz. Two sets of limits are given for the higher frequencies: one applicable before 1 June 2002 and a stricter one applicable from that date, with special protection for the Aeronautical Radio Navigation Service in the GNSS band.
Within the bands, the standard limits unwanted emissions in carrier-on and carrier-off states. For users, this means transmitters must be checked not only when active, but also for leakage or spurious output when transmission should be suppressed.
Control and Monitoring Functions (CMF)
SIST EN 301 426:2001 requires a minimum set of CMF to reduce the chance of unwanted transmission. The CMF include:
- Processor monitoring - detects processor hardware or software failure and forces carrier-off quickly
- Transmit subsystem monitoring - stops transmission if the frequency generation chain fails
- Power-on/Reset - keeps the LMES in carrier-off after power-up or reset
- Control Channel reception - prevents transmission unless control information is received correctly from the NCF
- Network control commands - accepts transmission enable, transmission disable and identification request commands
- Initial burst transmission - limits any initial bursts when no enable command is expected after power-on or reset
These functions matter because the LMES should not continue transmitting when its control path is lost or when an internal fault could create interference.
Environmental profile and test conditions
SIST EN 301 426:2001 ties compliance to the environmental profile declared by the applicant, including humidity, temperature and supply voltage. Tests are carried out within the declared operating limits, so the equipment must remain compliant across the conditions it is sold to handle.
The standard also states measurement uncertainty limits for the test methods. In practice, that gives test labs a defined margin for radiofrequency, power and spurious-emission measurements.
What terms does SIST EN 301 426:2001 define?
- Environmental profile - the range of operating conditions under which the equipment must comply.
- Applicant - the manufacturer, authorized representative, or person responsible for placing the apparatus on the market.
- carrier-off state - the LMES is not transmitting, either because it is not authorized or because it is authorized but silent.
- carrier-on state - the LMES is authorized to transmit and is actually transmitting.
- Control Channel (CC) - the channel used to receive control information from the NCF.
- Network Control Facility (NCF) - the network element that sends control information and commands to the LMES.
- Nominated bandwidth - the transmit bandwidth selected by the manufacturer to contain the useful transmission and define unwanted emissions limits.
- Equivalent Isotropically Radiated Power (EIRP) - the radiated power measure used for the emission limits above 1000 MHz.
Who uses SIST EN 301 426:2001?
Manufacturers and their authorized representatives use SIST EN 301 426:2001 when designing LMES equipment and preparing conformity evidence. Test laboratories use it to set up spurious-emission and control-function tests. Quality managers and buyers use it to confirm that a product is intended for the 1.5/1.6 GHz LMES market and that it addresses R&TTE essential requirements. Network operators and regulators use it as a reference for spectrum compatibility and interference control.
Which standards are used with SIST EN 301 426:2001?
The standard names these references:
- Directive 1999/5/EC - the R&TTE Directive that defines the essential requirement addressed by the standard.
- CISPR 16-1 - provides apparatus and methods for radiodisturbance and immunity measurements, including validation of the open area test site.
- Directive 98/34/EC - gives the procedure for providing information in the field of technical standards and regulations.
- TBR 26 - the predecessor technical basis for regulation on low data rate LMES in the same bands.
- ETS 300 254 - an earlier LMES standard on low bit rate data communications in the 1.5/1.6 GHz bands.
What does the SIST EN 301 426:2001 document contain?
The document contains frequency-band definitions, emission-limit tables, and detailed control-and-monitoring requirements. It also includes test-site and test-equipment descriptions, measurement uncertainty values, and step-by-step test methods for unwanted emissions, processor monitoring, transmit-subsystem monitoring, power-on/reset, Control Channel reception, network control commands and initial burst transmission.
Figures show the test arrangements for unwanted-emission measurements, and Annex A provides the EN Requirements Table (EN-RT). That annex is intended as a tabular summary of the requirements and a conformity-assessment aid for completed equipment.
