Scope
Main technical content: In addition to having a cross-frequency communication channel, this technology also increases the number of co-frequency communication channels by adopting the switching technology of co-frequency uplink and downlink channels. At the same time, it realizes the co-mingling and sharing of co-frequency and cross-frequency signals through a pair of optical modules for transmission. Its structure is simple and its performance is reliable. It features co-frequency and cross-frequency compatible operation modes, and is suitable for covering blind and weak areas of railway wireless communication. It can meet the needs of railway train wireless dispatching communication systems for voice communication and data transmission in different standard sections. Moreover, it also has an anti-theft alarm function.
