高铁多场景5G网络规划和性能验证

5G Network Planning and Performance Verification forMulti-scenario of High-speed Railway

高铁5G网络面临移动速度快、信号穿损大和多普勒频偏大的挑战。介绍了以3.5 GHz作为高铁5G网络主覆盖频率下的线路、隧道、声屏障场景的设备选型、站址规划和高铁5G切片专网,提出隧道5G网络建设的改进方案,并在某高铁全线进行了测试验证。

5G network for high-speed railway faces the challenges of fast movement,large signal penetration loss and large Doppler shift.It introduces the equipment selection,network construction planning and 5G slice network of high-speed railway,tun-nels and sound barriers with 3.5 GHz as the main coverage frequency of high-speed railway 5G network,proposes the im-provement scheme of 5G network construction for tunnels,and conducts testing and verification on the entire line of a high-speed railway.
