The present document specifies technical characteristics and methods of measurements for radio transmitters and receivers used in the Eurobalise transmission system. The system is used in railway environment for the communication between tracks and trains. 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 frequency bands listed in table 1 in accordance with the EC Decision 2013/752/EU [i.5] and ERC Recommendation 70-03 [i.2], 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 receive frequency band 2,5 MHz – 6,0 MHz OBE transmit frequency band 27,095 MHz ± 500 kHz Eurobalise transmit frequency band 4,234 MHz ± 1 MHz The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.1] under the conditions identified in annex A.
