Foreword
This Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical Committee
Satellite Earth Stations and Systems (SES).
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Directive 98/34/EC [4] (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 Directive 1999/5/EC of the European Parliament and of
the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual
recognition of their conformity ("the R&TTE Directive") [1].
Technical specifications relevant to Directive 1999/5/EC [1] are given in annex A.

National transposition dates
Date of adoption of this EN: 7 December 2007
Date of latest announcement of this EN (doa): 31 March 2008
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 30 September 2008
Date of withdrawal of any conflicting National Standard (dow): 30 September 2009

Introduction
The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to
cover all radio and telecommunications terminal equipment within the scope of the R&TTE Directive. The modular
structure is shown in EG 201 399.

Figure 1: EST System Overview
• The EST may transmit and receive data when the train is in motion and also when the train is stationary.
• The EST operates in a railway environment and, therefore, may be subject to occasional disturbances and
interruptions in the satellite link.
• The EST is operating as part of a satellite network (e.g. star, mesh or point-to-point) used for the distribution
and/or exchange of information.
• The EST is comprised of all the equipment, electrical and mechanical, from the antenna itself to the interface
with other communications equipment on a train (usually referred to as the terrestrial interface).
• The EST transmits on single carrier in the frequency range 14,00 GHz to 14,25 GHz, which is a portion of a
band allocated to the Fixed Satellite Services (FSS) (Earth-to-space).
• The EST receives in one or more frequencies within the range from 10,70 GHz to 12,75 GHz in bands
allocated to the Fixed Satellite Services (FSS) (space-to-Earth) or the Broadcast Satellite Service (BSS)
(space-to-Earth), depending on the ITU Region where the EST is located.
• The EST uses linear or circular polarization.
• The EST is designed to operate through a geostationary satellite (or a cluster of co-located geostationary
satellites) that is at least 3° away from any other geostationary satellite operating in the same frequencies and
over the same coverage area.
• The EST transmits at elevations greater than or equal to 7° relative to the local horizon.
• The EST is designed for unattended operation.
• The EST is controlled and monitored by a Network Control Facility (NCF). The NCF is outside the scope of
the present document.
The present document applies to the EST with its ancillary equipment and its various telecommunication ports, and
when operated within the boundary limits of the operational environmental profile as declared by the applicant and
when installed as required by the applicant's declaration or in the user documentation.

8 ETSI EN 302 448 V1.1.1 (2007-12)
The present document is intended to cover the provisions of Directive 1999/5/EC [1] (R&TTE Directive) Article 3.2,
which states that "… radio equipment shall be so constructed that it effectively uses the spectrum allocated to
terrestrial/space radio communications and orbital resources so as to avoid harmful interference".
NOTE 1: Operational requirements are defined by national administrations and by relevant ECC Decisions.
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of Article 3 of the Directive 1999/5/EC [1] (R&TTE Directive) may apply to equipment within the
scope of the present document.
NOTE 2: A list of such ENs is included on the web site http://www.newapproach.org/.

Foreword
This Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical Committee
Satellite Earth Stations and Systems (SES).
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Directive 98/34/EC [4] (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 Directive 1999/5/EC of the European Parliament and of
the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual
recognition of their conformity ("the R&TTE Directive") [1].
Technical specifications relevant to Directive 1999/5/EC [1] are given in annex A.

National transposition dates
Date of adoption of this EN: 7 December 2007
Date of latest announcement of this EN (doa): 31 March 2008
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 30 September 2008
Date of withdrawal of any conflicting National Standard (dow): 30 September 2009

Introduction
The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to
cover all radio and telecommunications terminal equipment within the scope of the R&TTE Directive. The modular
structure is shown in EG 201 399.

Figure 1: EST System Overview
• The EST may transmit and receive data when the train is in motion and also when the train is stationary.
• The EST operates in a railway environment and, therefore, may be subject to occasional disturbances and
interruptions in the satellite link.
• The EST is operating as part of a satellite network (e.g. star, mesh or point-to-point) used for the distribution
and/or exchange of information.
• The EST is comprised of all the equipment, electrical and mechanical, from the antenna itself to the interface
with other communications equipment on a train (usually referred to as the terrestrial interface).
• The EST transmits on single carrier in the frequency range 14,00 GHz to 14,25 GHz, which is a portion of a
band allocated to the Fixed Satellite Services (FSS) (Earth-to-space).
• The EST receives in one or more frequencies within the range from 10,70 GHz to 12,75 GHz in bands
allocated to the Fixed Satellite Services (FSS) (space-to-Earth) or the Broadcast Satellite Service (BSS)
(space-to-Earth), depending on the ITU Region where the EST is located.
• The EST uses linear or circular polarization.
• The EST is designed to operate through a geostationary satellite (or a cluster of co-located geostationary
satellites) that is at least 3° away from any other geostationary satellite operating in the same frequencies and
over the same coverage area.
• The EST transmits at elevations greater than or equal to 7° relative to the local horizon.
• The EST is designed for unattended operation.
• The EST is controlled and monitored by a Network Control Facility (NCF). The NCF is outside the scope of
the present document.
The present document applies to the EST with its ancillary equipment and its various telecommunication ports, and
when operated within the boundary limits of the operational environmental profile as declared by the applicant and
when installed as required by the applicant's declaration or in the user documentation.
