Foreword
This Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical Committee
Electromagnetic compatibility and Radio spectrum Matters (ERM), and is now submitted for the Vote phase of the
ETSI standards Two-step Approval Procedure.
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC [12] (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 [11] 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").
Technical specifications relevant to Directive 1999/5/EC [11] are given in annex A.

Proposed national transposition dates
Date of latest announcement of this EN (doa): 3 months after ETSI publication
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 6 months after doa
Date of withdrawal of any conflicting National Standard (dow): 18 months after doa

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 [13].

1 Scope
The present document applies to a system comprising the following radio equipment types:
1) an Onboard GSM Base Transceiver System (OBTS) supporting the GSM 1800 functions with specific
protocols for power constraints;
2) a Network Control Unit (NCU) preventing direct connection of the onboard mobile terminals with mobile
networks on the ground by raising the noise floor in the cabin.
These radio equipment types are capable of operating in all or any part of the frequency bands given below:
Table 1: Radiocommunications service frequency bands

Radiocommunications service frequency bands
Transmit 1 (OBTS) 1 805 MHz to 1 880 MHz
Receive 1 (OBTS) 1 710 MHz to 1 785 MHz
Transmit 2 (NCU) 460 MHz to 470 MHz
Transmit 2 (NCU) 921 MHz to 960 MHz
Transmit 2 (NCU) 1 805 MHz to 1 880 MHz
Transmit 2 (NCU) 2 110 MHz to 2 170 MHz

It applies to equipment for continuous and discontinuous transmission of data and digital speech.
The present document applies only to radio equipment using a dedicated transmitting antenna that is designed as an
indispensable part of the system for usage on board an aircraft.
The system covered by the present document operates in accordance with the operational requirements as outlined in
the Decision CEPT/ECC/DEC/(06)07 [14].
The present document covers the provisions of Directive 1999/5/EC (the 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".
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 R&TTE Directive may apply to equipment within the scope of the present
document.
NOTE: A list of such ENs is included on the web site http://www.newapproach.org.
The present document does not cover equipment compliance with relevant civil aviation regulations. In this respect, a
GSMOBA system, for its installation and operation on board an aircraft is subject to additional national or international
civil aviation airworthiness certification requirements, for example to EUROCAE ED-14E [10].

Foreword
This Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical Committee
Electromagnetic compatibility and Radio spectrum Matters (ERM).
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC [12] (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 [11] 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").
Technical specifications relevant to Directive 1999/5/EC [11] are given in annex A.

National transposition dates
Date of adoption of this EN: 11 April 2008
Date of latest announcement of this EN (doa): 31 July 2008
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 31 January 2009
Date of withdrawal of any conflicting National Standard (dow): 31 January 2010

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 [13].

1 Scope
The present document applies to a system comprising the following radio equipment types:
1) an Onboard GSM Base Transceiver System (OBTS) supporting the GSM 1800 functions with specific
protocols for power constraints;
2) a Network Control Unit (NCU) preventing direct connection of the onboard mobile terminals with mobile
networks on the ground by raising the noise floor in the cabin.
These radio equipment types are capable of operating in all or any part of the frequency bands given below:
Table 1: Radiocommunications service frequency bands

Radiocommunications service frequency bands
Transmit 1 (OBTS) 1 805 MHz to 1 880 MHz
Receive 1 (OBTS) 1 710 MHz to 1 785 MHz
Transmit 2 (NCU) 460 MHz to 470 MHz
Transmit 2 (NCU) 921 MHz to 960 MHz
Transmit 2 (NCU) 1 805 MHz to 1 880 MHz
Transmit 2 (NCU) 2 110 MHz to 2 170 MHz

It applies to equipment for continuous and discontinuous transmission of data and digital speech.
The present document applies only to radio equipment using a dedicated transmitting antenna that is designed as an
indispensable part of the system for usage on board an aircraft.
The system covered by the present document operates in accordance with the operational requirements as outlined in
the Decision CEPT/ECC/DEC/(06)07 [14].
The present document covers the provisions of Directive 1999/5/EC (the 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".
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 R&TTE Directive may apply to equipment within the scope of the present
document.
NOTE: A list of such ENs is included on the web site http://www.newapproach.org.
The present document does not cover equipment compliance with relevant civil aviation regulations. In this respect, a
GSMOBA system, for its installation and operation on board an aircraft is subject to additional national or international
civil aviation airworthiness certification requirements, for example to EUROCAE ED-14E [10].
