[0022] best practice
[0023] The optical fiber repeater with the same and different frequency forwarding functions provided by the present invention is used in the wireless dispatching communication system of railway trains in the railway system B communication system section (that is, the four-frequency group is single-duplex compatible), and realizes wireless communication blind areas and weak areas of coverage. As known, the above-mentioned railway train wireless dispatching communication system adopts the same and different frequency independent half-duplex working mode to carry out voice communication and data transmission, that is, the working frequency of the station platform and locomotive platform is 457~459MHz (center frequency) when working at the same frequency. 458MHz), the transmission frequency of the station platform and the reception frequency of the locomotive station are 467~469MHz (center frequency 468MHz) when the frequency is different, and the reception...
