The present document applies to 2,45 GHz Short Range Devices (SRDs) for use in Railway AVI which fulfil the Union Internationale des Chemins de fer (UIC) specifications (annex E) and are interoperable with the current UIC system except for the interrogator (Track Units (TU)) bandwidth. 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 as defined in the CEPT/ERC Recommendation T/R 70-03 [1].
