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 and ERC Recommendation 70-03, 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
Note OBE receive frequency band 2,5 MHz to 6 MHz (4,234 MHz centre frequency)
Eurobalise transmit frequency band 4,234 MHz ± 1 MHz
NOTE: EC decision for SRDs and ERC Recommendation 70-03 are providing the usage conditions for Eurobalise transmissions in frequency range 984 - 7 484 kHz (4,234 MHz centre frequency). The 27 MHz band is only used in the OBE for telepowering the Eurobalise, which is not in the scope of the present document.
The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU under the conditions identified in annex A.
