摘要
该文基于当地无线网络的路测扫频数据，对经典的COST231-Hata模型进行本地化校正，搭建基于GIS的无线网络覆盖仿真平台，以实现无线网络覆盖的模拟；在此基础上，针对城区无线通讯因基站密度过大普遍存在的越区覆盖问题进行了讨论，分析了基站载频、基站高度、以及天线俯仰角等对无线信号传播的影响，通过仿真平台模拟，调整相关工程参数以改善基站间的越区覆盖问题，进而实现网络的合理优化。
This paper realized the localization correction of COST231-Hata model based on the drive test data, and setup a simulation platform of wireless network coverage based on GIS. According to the problem of cross-zone coverage in dense urban area, the relationship between radiation frequency, station＇s height, antenna elevation angle and the cross-zone coverage has been discussed. Through simulation on platform, the relative parameters have been adjusted to solve the cross-zone coverage problem effextively. And the optimization of wireless network is realized.
