摘　　要：立足典型低空场景的业务需求,分析了5G低空覆盖所需的信号覆盖水平,并基于典型5G中频设备天线性能,参考3GPP推荐的低空传播模型,立体分层地计算分析了典型3扇区基站用于低空覆盖时的信号覆盖水平。评估了各类设备的低空覆盖能力以及适用的部署场景和最佳部署仰角,为5G低空通信网络部署提供了可借鉴的方案。Based on the service requirements of typical low-altitude scenarios,it analyzes the signal coverage level required for 5G low altitude coverage.Meanwhile,based on the antenna performance of typical 5G intermediate frequency equipment and the low-altitude propagation model recommended by 3GPP,it conducts a three-dimensional hierarchical calculation analysis of the signal coverage level of typical 3-sector base station for low-altitude coverage.Finally,it evaluates the low-altitude coverage capability of various equipment,as well as the applicable deployment scenarios and the optimal deployment tilt angle,and provides a reference solution for the deployment of 5G low-altitude communication networks.
