Satellite Personal Communications Networks (S-PCN); Mobile Earth Stations (MES), including handheld earth stations, for S-PCN in the 1,6/2,4 GHz bands under the Mobile Satellite Service (MSS); Terminal essential requirements

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:  -   1610-1626,5 MHz, (MES transmit) -   1613,8-1626,5 MHz (MES receive) and -   2483,5-2500 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 300 733 [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 Directiies and therefore, are not covered by this TBR.

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 one or more of the Mobile Satellite Service (MSS) frequency bands
given in table 1.
Table 1: Mobile Satellite Service (MSS) frequency bands
MSS frequency bands
MESs transmit 1 610 - 1 626,5 MHz
MESs receive 1 613,8 - 1 626,5 MHz
2 483,5 - 2 500 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 one or more of 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:
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.

2 Normative references
This TBR incorporates, by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to, or revisions of any of these publications
apply to this TBR only when incorporated in it by amendment or revision. For undated references the
latest edition of the publication referred to applies.

rate measuring apparatus for data transmission".
3 Definitions and abbreviations
3.1 Definitions
For the purposes of this TBR, the following definitions apply:
applicant: A party seeking an approval, or to place an S-PCN MES on the European market, i.e. the
manufacturer of the equipment, or his authorized representative, or an equipment supplier to the
European market.
carrier-on state (allocated a channel): An MES is in this state when it is transmitting a signal in a
continuous or non-continuous mode.
carrier-off state (idle mode): An MES is in this state when it is powered-on but not transmitting a signal,
i.e. not in the carrier-on state.
conducted measurement: A measurement of emissions from an antenna port of the MES made by
direct wired connection to the port.
Equivalent Isotropically Radiated Power (EIRP): The product of transmitter power and maximum
antenna gain, equivalent to an isotropic source radiating uniformly in all directions.
handheld: Indicates a PE MES which is self-contained and is small enough and light enough to be carried
and used during a call with one hand.
host-connected: Indicates an MES for which connection to or integration with host equipment is
necessary to offer functionality.
host equipment: Is any equipment which has a complete user functionality when not connected to the
MES, and to which the MES provides additional functionality, and to which connection is necessary for the
MES to offer functionality.
Installable Equipment (IE), Internally Mounted Equipment (IME) And Externally Mounted
Equipment (EME): An Installable Equipment (IE) is an equipment which is intended to be installed in a
vehicle. An IE may consist of one or several interconnected modules. The IE is composed of modules
