The 5G trial base station in Yuanping South Station of the Shuozhou-Huanghua Railway was put into operation on April 12, marking that mountainous stations of the railway under China Energy have entered a 5G era.
Workers test the 5G transmission equipment.
The west section (Shenchi-Xibaipo) of the Shuozhou-Huanghua Railway runs through mountainous areas, with 60% of its stations built in deep mountains with weak signals. Previously, construction of 4G networks solved slow connection of communications devices such as cell phones and two-way radios and the weak signals in some sections and long tunnels. To further enhance the communication networks to meet the demand of heavy-haul intelligent railroads, Shuohuang Railway Co., Ltd. worked with technical experts from telecommunication operators to do field surveys on mobile signals in remote mountainous areas and long tunnels and explore the feasibility of covering them with commercial 5G networks. Through building three 5G trial base stations in Yuanping, Shenchi and Xibaipo and connecting them with the existing information monitoring system, a high-efficiency data transmission channel has been established to facilitate real-time video monitoring, personnel positioning, and emergency malfunction remote settlement. Subsequently, similar base stations will be constructed by groups to cover all major railway stations in mountainous areas.
After several rounds of network optimization and testing, all of the three pilot stations can achieve HD voice and video calls and high-speed data uploading and downloading, laying a foundation for realizing full 5G coverage of key sections and long tunnels in mountainous regions.
