10、ble 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 referencing by CEPT/ERC Recommendation T/R 70-03 4. The Interrogator bandwidth is limited to 8 MHz shared within five channe
11、ls: - - for data transmission only; - with a Radio Frequency (RF) output connection and specified antenna or with an integral antenna; 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. The present docum
12、ent is a product standard covering various Railway applications where the data transmission of the system will be active only during the presence of the train. The present document covers fixed installed interrogators (TUS) and transponders (mobile stations). For certain measurements the transponder
13、s are measured together with the whole interrogating system. The in-track base station (interrogator) transmit and receive modulations are a combination of Amplitude Shift Keying (ASK) and Frequency Shift Keying (FSK) respectively. The present document supports the necessary transmitter and receiver
14、 data rates between 192 kbit/s and 3 84 kbit/s according to the type of transaction. It covers the minimum characteristics considered necessary in order to make the best use of the available frequencies. It does not necessarily include all the characteristics which may be required by a user, nor doe
15、s it necessarily represent the optimum performance achievable. The present document includes specifications for methods of measurement for equipment fitted with antenna sockets andor integral antenna. The technical requirements of the present document apply under the environmental profile for operat
16、ion of the equipment, which shall be declared by the manufacturer. The equipment shall comply with all the technical requirements of the present document at all times when operating within the boundary limits of the declared operational environmental profile. The present document is intended to cove
17、r the provisions of article 3.2 of Directive 1999/5/EC i (R 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“.
