Recently, the 5G-R railway communication training system, which was built by Nanjing Taitong Technology Co., Ltd., has been integrated and debugged in Jilin Railway Vocational and Technical University and officially put into teaching. The system is oriented to the construction of a new generation of railway mobile communication, and realizes the deep integration of the 5G-R private network and the high-speed train control system. Figure 1: Network Management Monitoring Platform In this project, Nanjing Taitong Technology mainly undertakes the supply and technical support of core communication products such as 5G-R core network, BBU baseband unit, EU expansion switching unit, RRU radio remote unit and supporting switching equipment. The whole set of training system is completely calibrated to the technical standards of the railway site, and it is completely repeated.

On July 9, 2026, China Communications and Transportation Association held a meeting in Beijing to evaluate the scientific and technological achievements of "DRTD Digital Optical Fiber Repeater Technology and Application" developed by Nanjing Taitong Technology Co., Ltd. This evaluation meeting will invite industry authoritative experts to form an evaluation Committee. According to the review process, Nanjing Taitong Technology fully reported the research and development process, product composition and characteristics of the results. After listening to the report and watching the live demonstration, the experts conducted in-depth questions and discussions and fully affirmed the results. This project closely tracks the digital wireless dispatching signal system (DRTD) of China Railway.

On July 8, 2026, China Communications and Transportation Association organized a meeting in Beijing to review the outline of the group standard "Technical Requirements of 5G-F Wireless Communication System for Ultra-high Speed Maglev Traffic" led by Nanjing Taitong Technology.
