The present document covers the technical requirements for radio transmitters and receivers used in the Euroloop transmission system. The system is only used in railway systems. It applies to the following two equipment units as is shown in figure 1:
The On-Board Equipment (OBE) receiving the Euroloop signal and the OBE comprises a receiver fitted with a dedicated antenna.
The Track-Side Equipment (Euroloop) transmitting the Euroloop signal that is always installed in an inner or outer foot of a rail. The Euroloop comprises DSSS-BPSK-modulated transmitter fitted with a dedicated antenna. It is always switched on but is only transmitting in the presence of a train. The present document is intended to cover the provisions of Directive 1999/5/EC [i.6] (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".

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. 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".
