摘　　要：为了加强移动设施建设的针对性,有效利用频率资源、提高网络质量,利用射线跟踪法对高楼电梯内单电梯与双电梯井道模型的移动通信场强传播进行仿真和分析。结果表明,对于单电梯井道,在全球移动通信系统(GSM)信号、3G和WiFi信号仿真结果与测量结果一致性良好;在4G和5G信号中,建议将天线间隔分别设置在9~12 m和8 m时较适宜。同时,双电梯井道在不同频段下场强分布仿真也得到了验证。通过建立无线传播仿真模型,为4G及5G通信系统的电梯覆盖提供了依据。In order to strengthen the pertinence of mobile facility construction,effectively use frequency resources and improve network quality,the ray tracing method is utilized to simulate and analyze the field strength propagation of mobile communication in single elevator and double elevator shaft models in high⁃rise elevators.The results show that for a single elevator shaft,the simulation results of global system for mobile communications(GSM)signals,3G signals,and WiFi signals closely align with the measured results.As for 4G and 5G signals,it is suggested that the antenna spacing should be set at 9~12 m and 8 m,respectively.Additionally,the simulation of field strength distribution of double elevator shaft in different frequency bands has also been verified.By establishing a wireless propagation simulation model,it provides a basis for elevator coverage of 4G and 5G communication systems.
