摘要
中国正在加速5G网络在全国范围内的大规模部署。5G移动通信网络将极大地提升个人用户的移动互联网体验,更会为实现工业物联网发挥无可替代的巨大作用。5G在室外环境下的传播特性会制约5G网络的规划与部署,直接影响宽带数据业务的覆盖,也影响工业物联网的发展。因此,5G在室外场景下的传播模型建设显得无比重要。本文针对3.5 GHz频段下的5G室外场景,实测了无线电波的路径损耗,通过对传播模型的匹配与校正,得出了符合3.5GHz无线电波在当下户外场景下的路径损耗模型。
5G network is being massively deployed in China nationwide.5G communication technology will greatly promote users’experience,andvalue added for industry internet of things.The 5G propagation characteristics in outdoor scenarios will restrict its planning and deployment,and hence impacting the coverage of broadband data service and the development of industry application.Therefore,the modelling of 5G propagation in outdoor scenarios is of great importance.This paper focuses on 5G outdoor scenarios and analyzes the path loss of the 5G signals experienced at frequency 3.5GHz.The propagation models for 3.5GHz is calibrated and discussed.
