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 mandate M/364 from the European Commission issued under Council Directive 98/34/EC [i.1] (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 [i.2] 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 [i.2] are given in annex A. These specifications are complementary with the system and interoperability requirements for these devices established under Commission Decision 2004/447/EC [i.3]. In addition, relevant parts of EN 50121 [i.4] are applicable for the electromagnetic compatibility of railway applications (part 3-2 for the OBE and part 4 for the Eurobalise equipment).

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 [i.5]. The Eurobalise transmission system is defined by the specifications of the UNISIG consortium [i.6] and [i.7]. SIST EN 302 608 V1.1.1:2009

ETSI ETSI EN 302 608 V1.1.1 (2008-11) 6 1 Scope The present document covers the technical requirements for radio transmitters and receivers used in the Eurobalise transmission system. The system is only used in railway systems. It applies to the following equipment units: a) the On-Board Equipment (OBE) Tele-powering the Eurobalise; and b) the Eurobalise that is always installed in between the rails. The OBE comprises a transmitter (normally un-modulated) and a receiver fitted with an integral or dedicated antenna. The Eurobalise FSK-modulated transmitter is Tele-powered by the OBE and has an integral antenna. The Eurobalise transmission system operates in accordance with ERC Recommendation 70-03 [i.8], annex 4. These radio equipment types are capable of operating at the following frequencies as given in table 1. Table 1: Radio communications frequencies

Radio communications frequencies OBE transmit centre frequency 27,095 MHz Eurobalise transmit centre frequency 4,234 MHz

The present document is intended to cover the provisions of Directive 1999/5/EC [i.2] (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".

Figure 2: Eurobalise transmitter mask The defined in-band frequency range is limited to the frequency range 4,234 MHz ± 1 MHz. The maximum value in the graph of figure 2 is 9 dBµA/m. NOTE: ERC Recommendation 70-03 [i.8], annex 4 recommends a maximum duty cycle of 1 % for the Eurobalise transmitter. This duty cycle can not be exceeded during normal operation due to the fact that the train never stops above the Eurobalise, i.e. the train only stops after the Eurobalise has been passed. In principle, it is impossible to exceed the duty cycle with moving trains due to the distance between trains versus Eurobalise operating range. The provider shall declare the maximum duty cycle to not exceed 1 %. 4.1.3.4 Maximum Allowable Measurement Uncertainty See table 5 in clause 6. 4.1.4 Eurobalise Unwanted Emissions 4.1.4.1 Definition This test only applies to Eurobalises. Unwanted emissions consist of out-of-band and spurious emissions outside the frequency range 27,095 MHz ± 500 kHz as defined in clause 4.1.1.3 and outside the frequency range 4,234 MHz ± 1 MHz as defined in clause 4.1.3.3. 4.1.4.2 Test Procedure This test is performed using a radiated measurement (see clause 7.4).
