ElectroMagnetic Compatibility and Radio Spectrum Matters (ERM);Short Range Devices (SRD);Automatic Vehicle Identification (AVI) for railways operating in the 2,45 GHz frequency range;Part 1: Technical characteristics and methods of measurement

Scope

The present document applies to a dedicated 2,45 GHz Short Range Device (SRD) microwave link intended for a European wide data communication system for Railway applications, Automatic Vehicle Identification (AVI).which fulfil the relevant Union Internationale des Chemins de fer (UIC) specifications (see Bibliography) and are interoperable with the current UIC system except for the interrogator (Track Units (TU)) bandwidth. The present document contains the technical characteristics for radio equipment and is referenced by CEPT/ERC
Recommendation T/R 70-03 [1].
The Interrogator bandwidth is limited to 8 MHz shared within five channels:
- with a Radio Frequency (RF) output connection and specified antenna or with an integral antenna;
- for data transmission only;
- operating on radio frequencies in the 2,446 GHz to 2,454 GHz Industrial, Scientific and Medical (ISM) band,
with power levels up to 500 mW e.i.r.p.
