The present document covers the technical requirements for radio transmitters and receivers used in the Euroloop transmission system. The system is used in railway systems. The present document applies to the following equipment: 1) The On-Board Equipment (OBE) receiving the Euroloop signal and the OBE comprises a receiver fitted with a dedicated antenna. 2) The Track-Side Equipment (Euroloop) transmitting the Euroloop signal that is always installed in an inner or outer foot of a rail. The Euroloop transmission system operates in frequency bands listed in table 1 in accordance with the EC Decision 2013/752/EU [i.2], and ERC Recommendation 70-03 [i.3], annex 4. These radio equipment types are capable of operating at the following frequencies as given below in table 1. Table 1: Radio communications frequencies Radio communications frequencies OBE receive frequency band 11,1 -16,0 MHz OBE transmit frequency band 27,09 – 27,10 MHz Euroloop receiver frequency band 27,09 – 27,10 MHz Euroloop transmit frequency band 11,1 -16,0 MHz Euroloop transmit modulation BPSK, DSSS chip rate 4,516 MHz The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference.
