SIST EN 301 681:2001
(Main)Satellite Earth Stations and Systems (SES); Harmonized EN for Mobile Earth Stations (MESs) of Geostationary mobile satellite systems, including handheld earth stations, for Satellite Personal Communications Networks (S-PCN) in the 1,5/1,6 GHz bands under the Mobile Satellite Service (MSS) covering essential requirements under Article 3.2 of the R&TTE Directive
- Abstract
S-PCN terminals working with Geostationnary Satellites This EN is intended to define the minimum performance requirements and technical characteristics of Mobile Earth Stations (MES) with both transmit and receive capabilities for operation in a Geostationnary Satellite Personal Communication Network (S-PCN). An S-PCN MES may be handheld, portable, vehicle-mounted, host connected, semi-fixed or fixed equipment, or may be an element in a multi-mode terminal; it may consist of a number of modules with associated connections and user interface, or may be a self contained single unit. This EN will specify the requirements of the S-PCN MES element of the terminal operating in one or more of the MSS frequency bands dedicated to geostationnary S-PCNs in the 1,5/1,6 GHz band. The requirements to be defined may cover following two major categories: unwanted emission limits: to protect other radio services from harmful interference generated by the MES in normal use; MES Control and Monitoring Functions (CMF): to protect other radio services from unwanted transmissions from the MES. The CMF in each MES is capable of answering to commands from the Network Control Facilities (NCF) for the operating S-PCN.

SIST EN 301 681:2001 is an ETSI harmonized European standard published by SIST for Mobile Earth Stations (MES) used in Satellite Personal Communications Networks (S-PCN). SIST EN 301 681:2001 specifies minimum performance requirements, technical characteristics, and conformance tests for geostationary mobile satellite MES operating in the 1,5/1,6 GHz Mobile Satellite Service (MSS) bands. The standard supports the essential requirements of Article 3.2 of the R&TTE Directive, with a focus on spectrum use and avoidance of harmful interference.
What does SIST EN 301 681:2001 specify?
SIST EN 301 681:2001 specifies the MES element of S-PCN terminals for geostationary mobile satellite systems, including handheld earth stations, with transmit and receive capability and EIRP less than or equal to 15 dBW. The document is written for equipment used in the 1626,5 MHz to 1660,5 MHz transmit band and the 1525 MHz to 1559 MHz receive band.
The standard covers handheld, portable, vehicle-mounted, host-connected, semi-fixed, fixed, and multimode equipment. The Network Control Facility (NCF) is outside the scope, but the MES is required to respond to NCF commands.
Other ENs may also apply when other essential requirements of the R&TTE Directive are relevant.
| Annex | What it covers |
|---|---|
| Annex A | The EN Requirements Table (EN-RT), a summary of the requirements and their mandatory or optional status |
| Annex B | An explanation of nominated bandwidth, including how Bn is chosen and interpreted |
The document is organized into scope, references, definitions and abbreviations, technical requirement specifications, and testing for compliance.
What are the key requirements of SIST EN 301 681:2001?
SIST EN 301 681:2001 centers on controlling unwanted emissions and ensuring that the MES stops or limits transmission when network control requires it. In practice, this means the radio must stay inside defined spectral limits and must not keep transmitting when control logic or network authorization says otherwise.
Environmental operating conditions
Clause 4.1 requires compliance over the declared environmental profile. The MES must work across -10 °C to +55 °C, over the declared voltage extremes, and under the vibration profile stated in the standard. This matters because the equipment has to meet the radio requirements in real operating conditions, not only in a nominal lab state.
Unwanted emissions in carrier-on state
Clauses 4.2.1 and 4.2.2 define emission limits outside the operating band and in the adjacent protected bands. The limits depend on frequency range, measurement bandwidth, and whether peak or average measurement is used; for CDMA systems, the limits are reduced according to the number of simultaneously transmitting MESs declared by the manufacturer. This is what drives the transmitter mask, lab measurements, and product declarations.
Unwanted emissions in carrier-off state
Clause 4.2.3 limits emissions when the MES is powered and authorized but not transmitting. This protects other radio services from leakage, spurious output, and unintended bursts. The test limits are especially important for standby behavior, wake-up logic, and any periodic background transmission.
Control and Monitoring Functions (CMF)
Clause 4.2.4 requires processor monitoring, transmit frequency generation sub-system monitoring, network control authorization, and network control reception behavior. The MES must suppress transmission within 1 s after a detectable processor fault and within 5 s after a transmit-frequency-generation failure, remain silent on power-up until synchronized, and respond to disable/enable and frequency-control commands from the NCF. In practice, the software and control paths must be designed so the radio fails quiet.
Multimode and identification functions
Clause 4.2.4.5 requires any fellow radiostation in a dual-mode or multimode terminal to stay silent unless the right network control channel is received. Clause 4.2.5 requires a unique MES Identification Code (MIC) that the user cannot change through normal access, and the MES must transmit that MIC when commanded. This is how the network identifies and controls each terminal.
Radio astronomy protection
Clause 4.2.6 requires the MES to support transmission disable in the 1660 MHz to 1660,5 MHz band. This gives the network a way to protect radio astronomy operation in that band.
What terms does SIST EN 301 681:2001 define?
- Carrier-on state - the MES is authorized by the NCF to transmit and is actually transmitting.
- Carrier-off state - the MES is authorized but not transmitting, or is not authorized to transmit.
- Equivalent Isotropically Radiated Power (EIRP) - transmitter power combined with antenna gain, used here to express emission limits.
- Nominated bandwidth (Bn) - the frequency interval chosen by the applicant to contain the relevant transmitted spectrum and stay within the operational band.
- Network Control Facility (NCF) - the network function that sends control commands to the MES.
- Special Test Equipment (STE) - test equipment used to control the MES during conformance testing.
- MES Identification Code (MIC) - the unique code that identifies an MES within its S-PCN.
- host-connected - an MES that needs connection to host equipment to provide its functionality.
Who uses SIST EN 301 681:2001?
SIST EN 301 681:2001 is used by MES manufacturers, their authorized representatives, and conformity assessment laboratories. It is also useful for satellite network operators and engineers who need the terminal to work with NCF control, frequency planning, and emission control.
Quality managers and buyers use it to specify what a geostationary S-PCN terminal must prove in testing. Test labs use it to set up radiated and conducted measurements, verify CMF behavior, and document results.
Which standards are used with SIST EN 301 681:2001?
SIST EN 301 681:2001 references Directive 1999/5/EC as the legal basis for radio spectrum conformity. It also cites Council Directive 89/336/EEC for EMC and Council Directive 73/23/EEC for electrical safety context.
For measurement and test practice, the standard cites ITU-T Recommendation O.153 and CISPR 16-1. The bibliography names EN 301 682 for NCF requirements, EN 301 489-20 for EMC conditions for MES in MSS, IEC 60068-2-1, IEC 60068-2-2, and IEC 60068-2-64 for environmental testing, and ITU-R Recommendation M.1480 for related essential technical requirements.
What does the SIST EN 301 681:2001 document contain?
SIST EN 301 681:2001 contains emission limits in tables for carrier-on and carrier-off states, plus the environmental test conditions and test equipment uncertainties used to assess them. It also provides detailed test methods and test setups for radiated and conducted emissions, including measurement arrangements, spectrum-analyzer settings, and test modes.
The document uses figures to show how to test MES emissions and control behavior, and it gives step-by-step procedures for network control authorization, transmission disable/enable, frequency control, multimode behavior, and MIC transmission. Annex A provides a one-page requirements summary for conformity work, and Annex B explains how to choose and interpret nominated bandwidth for a given MES.
