摘　　要：对移动通信运营商无线通信网络建设情况、技术特点和终端主要技术指标进行分析,提出4G/5G网络覆盖中存在的问题和产生原因,5G频谱的提高会增大无线传播损耗,影响移动通信网络的深度覆盖。基于仿真实验对频偏校正技术,根据皮基站规划指标对不同区域天线安装间距提出建议,达到5G网络深度全覆盖。Analyze the construction situation,technical characteristics and main technical indicators of the mobile communication operator's wireless communication network,and put forward the problems and causes in the 4G/5G network coverage.The increase of the 5G spectrum will increase the wireless transmission loss and affect the mobile communication network deep coverage.Based on the simulation experiment for frequency offset correction technology,suggestions are made for the installation distance of antennas in different areas according to the planning indicators of PRRU base stations,so as to achieve the deep and full coverage of 5G network.

关 键 词：5G网络 频偏校正 深度覆盖 皮基站
