Abstract

This TBR specifies those technical requirements under Article 4 of Council Directive 93/97/EEC [1] that apply to Mobile Earth Station (MES) equipment with both transmit and receive capabilities for operation in a Satellite - Personal Communications Network (S-PCN).  These MESs include handheld, portable and vehicle mounted equipment or may be a component in a multi-mode treminal; they may consist of a number of modules with associated connections and user interface, or may be self contained, single units. If the MES is a component in a multi-mode terminal, this TBR applies only to the MES component of the terminal, unless otherwise stated.  The frequency bands within which the MESs operate as as follows:  -1980-2010 MHz, (MES transmit) -2170-2200 MHz (MES receive).  The technical requirements in this TBR are in two major categories:  unwanted emission: to protect terrestrial and other satellite radio services from harmful interference generated by the MES in normal use;  MES control and monitoring: to speicfy the a minimum set of Control and Monitoring Functions (CMF) that shall be  implemented in each MES in order to minimise the probability that they originate unwanted transmissions that may give rise to harmful interference to other systems.  These requirements are taken from ETS 300 734 [3].  Network Control Facilities (NCF) for MES networks are defined by reference to  ETS 300 735 [2].  This TBR does not contain the essential requirements under articles 4f and 4g for interworking via the public telecommunications network, and does not provide any guarantee of correct interworking between MES equipment.  The Terminal Directive 91/263/EEC Articles 4a and 4b are covered by other Directives and therefore, are not covered by this TBR.

SIST TBR 042:1999 is the Slovenian standard identical to ETSI TBR 042 Edition 1, published by SIST. It specifies terminal essential requirements for Mobile Earth Stations (MES) used in Satellite Personal Communications Networks (S-PCN) in the 2,0 GHz bands under the Mobile Satellite Service (MSS). The document is aimed at applicants, manufacturers, suppliers, and test laboratories that need to assess MES equipment with transmit and receive capability, including handheld, portable, vehicle-mounted, host-connected, semi-fixed, fixed, and multi-mode implementations.

What does SIST TBR 042:1999 specify?

SIST TBR 042:1999 specifies the technical requirements that apply to MES equipment operating in the MSS uplink and downlink bands. The scope is centered on two practical topics: unwanted emissions and MES Control and Monitoring Functions (CMF), because these are the main ways an MES can interfere with other systems.

The standard is organized into clauses 1 to 9, with normative annexes that define how to test the equipment and how to interpret the results.

AnnexWhat it covers
Annex AGeneral test requirements, test modes, STE, LTE, measurement uncertainty, and test report content
Annex BEnvironmental conditions and testing of host-connected equipment
Annex CProcedures for radiated emissions measurements
Annex DProcedures for conducted emissions measurements
Annex EExplanation of nominated bandwidth
Annex FTBR Requirements Table
Annex GBibliography

The scope is limited to the MES radio interface. It focuses on terminal essential requirements for the S-PCN MES, not on public telecommunications network interworking.

What are the key requirements of SIST TBR 042:1999?

SIST TBR 042:1999 requires an MES to control its emissions, react safely to faults, and respond to network control. In practice, this means the equipment must stay within emission masks, shut down transmission when needed, and support conformance testing in repeatable test modes.

Unwanted emissions outside the operating band

Clauses 5.3 to 5.5 set limits for unwanted emissions outside the band 1 980,1 to 2 009,9 MHz while the MES is in carrier-on state. The limits vary by frequency range and use peak or average measurement methods, with specific measurement bandwidths.

For an engineer or test lab, this means the MES must be checked at the minimum and maximum transmit frequencies, at maximum transmit power, and with the specified test modulation. Radiated or conducted testing is allowed depending on the equipment configuration.

Unwanted emissions inside and near the operating band

Clause 6 sets tighter requirements close to the carrier, within 1 978,1 to 2 011,9 MHz. The limits depend on whether the carrier is TDMA or CDMA, and the offset is measured from the edge of the nominated bandwidth.

This matters because close-in emissions are the most likely to disturb other users of the same or adjacent spectrum. The standard requires the whole nominated bandwidth to stay inside the declared operational band.

Carrier-off emissions

Clause 7 covers unwanted emissions when the MES is powered on but not transmitting. The equipment must remain within the carrier-off emission limits across the defined spectrum.

In practice, this is the idle-state check. It helps confirm that a powered-on terminal does not radiate significant energy simply because it is switched on.

Control and Monitoring Functions

Clause 8 requires CMF that prevent uncontrolled transmission. The MES must monitor its processor and transmit frequency generation sub-system, detect failures, and suppress transmission after a fault is detected.

The same clause requires network control authorization: after POWER-ON, the MES must stay in a non-transmitting state until it is synchronized to the appropriate network control channel. It must also stop transmitting within 30 s after losing that channel.

Network control reception and multi-mode behavior

Clause 8.3.2 requires the MES to set its carrier frequency according to commands from the Network Control Facility (NCF). Clause 8.4 requires fellow radio stations in a dual-mode or multi-mode terminal not to transmit unless they receive the appropriate network control channel for their own system.

This is important for devices that combine several radio systems, because one mode must not start transmitting without network control just because another mode is active.

Equipment identity

Clause 9 requires each MES to have a unique MES Identification Code (MIC) within its S-PCN. The MIC must not be alterable by normal user actions, and the MES must transmit its identification code when an appropriate NCF command is received.

That gives the network a reliable way to identify the terminal during operation and testing.

Test setup and environmental coverage

Annexes A and B add practical test conditions. The MES is tested in defined test modes, under specified temperature, voltage, and vibration conditions, and host-connected equipment can be tested either as a combined system or with a representative test jig.

For buyers and quality managers, this matters because conformance is not just a bench check. The device must perform across declared operating conditions and in the configuration in which it will actually be used.

What terms does SIST TBR 042:1999 define?

  • Applicant - the party seeking approval or market placement of the S-PCN MES, usually the manufacturer, authorized representative, or supplier.
  • Carrier-on state - the MES is transmitting, whether the signal is continuous or intermittent.
  • Carrier-off state - the MES is powered on but not transmitting.
  • Control and Monitoring Functions (CMF) - the MES functions that monitor itself and respond to network control so it avoids causing unwanted transmissions.
  • Network Control Facility (NCF) - the network-side control function that sends commands to the MES.
  • Nominated bandwidth (Bn) - the frequency interval that contains the useful transmission and is used to define the unwanted-emissions mask.
  • Special Test Equipment (STE) - equipment used by the test laboratory to control the MES and provide the required network-control conditions during testing.
  • MES Identification Code (MIC) - the unique identification code assigned to an MES within its S-PCN.

Who uses SIST TBR 042:1999?

This standard is used by MES manufacturers, design teams, and their authorized representatives when they prepare equipment for approval or market placement. It is also used by accredited test laboratories that perform conformance testing of radiated and conducted emissions, control behavior, and identification response.

Network operators and system integrators use the concepts in the standard when they define the operational band, nominated bandwidth, and NCF behavior for an S-PCN. Quality managers and buyers use it to check whether a terminal is a handheld, portable, vehicle-mounted, host-connected, or multi-mode MES that can be tested and documented against the same essential requirements.

What changed in SIST TBR 042:1999 from the previous edition?

SIST TBR 042:1999 is identical to TBR 042 Edition 1.

Which standards are used with SIST TBR 042:1999?

  • CCITT Recommendation O.153 - defines the pseudo-random bit sequence used as the test modulating signal in Annex A.
  • ETS 300 734 - provides the related MES technical requirements referenced in the foreword and bibliography.
  • ETS 300 735 - defines the Network Control Facilities for S-PCN that generate the control commands used in CMF tests.
  • IEC Publication 68-2-1 - provides cold environmental test guidance used for temperature conditioning.
  • IEC Publication 68-2-2 - provides dry-heat environmental test guidance used for temperature conditioning.
  • IEC Publication 68-2-36 - provides random-vibration test guidance used in Annex B.

What does the SIST TBR 042:1999 document contain?

SIST TBR 042:1999 contains the full test-oriented structure needed to assess an MES against its essential requirements. Clause 4 explains how the equipment is presented for testing, including active antennas, host-connected equipment, and the information the applicant must supply. Clauses 5 to 7 define the emission masks and the measurement methods for carrier-on and carrier-off states.

The document includes detailed measurement procedures for radiated emissions in Annex C and conducted emissions in Annex D, with specific test arrangements and reference positions. Annex E explains how nominated bandwidth is interpreted, and Annex F maps the requirement topics to the TBR Requirements Table. The figures, tables, and procedures are written for conformance testing, not for product marketing descriptions or general background only.

Foreword
This Technical Basis for Regulation (TBR) has been produced by the Satellite Earth Stations and Systems
(SES) Technical Committee of the European Telecommunications Standards Institute (ETSI).
The present document has been produced by ETSI in response to a mandate from the European
Commission issued under Council Directive 83/189/EEC (as amended) laying down a procedure for the
provision of information in the field of technical standards and regulations.
The present document is intended to become a Harmonized Standard, the reference of which will be
published in the Official Journal of the European Communities referencing the Council Directive
93/97/EEC of 29 October 1993 supplementing Directive 91/263/EEC in respect of satellite earth station
equipment ("the SES Directive").
A common technical regulation may be established by the European Commission in accordance with the
Directive.
Technical specifications relevant to the SES Directive are given in annex F.

1 Scope
This Technical Basis for Regulation (TBR) specifies those technical requirements under Article 4 of
Council Directive 93/97/EEC (SES Directive), supplementing Council Directive 91/263/EEC (TTE
Directive), in respect of satellite earth station equipment that apply to Mobile Earth Station (MES)
equipment with both transmit and receive capabilities for operation in a Satellite - Personal
Communications Network (S-PCN), in the Mobile Satellite Service (MSS) frequency bands given in
table 1.
Table 1: Mobile Satellite Service (MSS) frequency bands
MSS frequency bands
MESs transmit 1 980 to 2 010 MHz
MESs receive 2 170 to 2 200 MHz
An S-PCN MES may be a 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.
If the MES is an element in a multi-mode terminal, unless otherwise stated in this TBR, its requirements
apply only to the S-PCN MES element of the terminal operating in the MSS frequency bands given in
table 1.
The technical requirements in this TBR are applied under Articles 4.1 and 4.3 of the SES Directive
referencing Article 4(e) of the TTE Directive, concerning effective use of the radio frequency spectrum,
including the effective use of orbital resources and the avoidance of harmful interference between space-
based and terrestrial communications systems and other technical systems. These requirements are in
two major categories:
unwanted emissions 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 its S-PCN.
NOTE: The requirements for Network Control Facilities (NCF) for S-PCN are contained in
ETS 300 735 (see annex G).
There are no technical requirements in this TBR under:
- Articles 4.1 and 4.4 of the SES Directive, referencing Article 4(c) of the TTE Directive as there are
no EMC requirements specific to the S-PCN MESs, nor under:
- Article 4.1 of the SES Directive, referencing Article 4(d) of the TTE Directive;
- Articles 4.1 and 4.5 of the SES Directive, referencing Article 4(f) of the TTE Directive;
- Articles 4.1 and 4.6 of the SES Directive, referencing Article 4(g) of the TTE Directive;
as, for the purposes of the SES Directive and the TTE Directive, the radio interface between the MES and
the S-PCN network is not regarded as a network termination point of a public telecommunications
network.
An MES may be subject to additional or alternative requirements in other TBRs depending on its
functionality, in particular if it supports a service which is considered a justified case for regulation of
terminal equipment interworking via the public telecommunications network.

1 Scope
This Technical Basis for Regulation (TBR) specifies those technical requirements under Article 4 of
Council Directive 93/97/EEC (SES Directive), supplementing Council Directive 91/263/EEC (TTE
Directive), in respect of satellite earth station equipment that apply to Mobile Earth Station (MES)
equipment with both transmit and receive capabilities for operation in a Satellite - Personal
Communications Network (S-PCN), in the Mobile Satellite Service (MSS) frequency bands given in
table 1.
Table 1: Mobile Satellite Service (MSS) frequency bands
MSS frequency bands
MESs transmit 1 980 to 2 010 MHz
MESs receive 2 170 to 2 200 MHz
An S-PCN MES may be a 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.
If the MES is an element in a multi-mode terminal, unless otherwise stated in this TBR, its requirements
apply only to the S-PCN MES element of the terminal operating in the MSS frequency bands given in
table 1.
The technical requirements in this TBR are applied under Articles 4.1 and 4.3 of the SES Directive
referencing Article 4(e) of the TTE Directive, concerning effective use of the radio frequency spectrum,
including the effective use of orbital resources and the avoidance of harmful interference between space-
based and terrestrial communications systems and other technical systems. These requirements are in
two major categories:
unwanted emissions 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 its S-PCN.
NOTE: The requirements for Network Control Facilities (NCF) for S-PCN are contained in
ETS 300 735 (see annex G).
There are no technical requirements in this TBR under:
- Articles 4.1 and 4.4 of the SES Directive, referencing Article 4(c) of the TTE Directive as there are
no EMC requirements specific to the S-PCN MESs, nor under:
- Article 4.1 of the SES Directive, referencing Article 4(d) of the TTE Directive;
- Articles 4.1 and 4.5 of the SES Directive, referencing Article 4(f) of the TTE Directive;
- Articles 4.1 and 4.6 of the SES Directive, referencing Article 4(g) of the TTE Directive;
as, for the purposes of the SES Directive and the TTE Directive, the radio interface between the MES and
the S-PCN network is not regarded as a network termination point of a public telecommunications
network.
An MES may be subject to additional or alternative requirements in other TBRs depending on its
functionality, in particular if it supports a service which is considered a justified case for regulation of
terminal equipment interworking via the public telecommunications network.
