This Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical Committee

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

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

Technical specifications relevant to Directive 1999/5/EC [11] are given in annex A.

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

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

2) a Network Control Unit (NCU) preventing direct connection of the onboard mobile terminals with mobile

These radio equipment types are capable of operating in all or any part of the frequency bands given below:

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

The system covered by the present document operates in accordance with the operational requirements as outlined in

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

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

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].
