| 摘 要： | 利用GIS能将蜂窝网络数据库中空间与非空间数据相结合的优势,来提供必要的参数,以更准确地预测蜂窝网络的覆盖强度,研究设计了一种基于COST-231-Walfisch-Ikegami的GIS模型,用来预测越南胡志明市移动蜂窝网络的信号强度,该模型可以帮助确定无线电的视距和非视距情况。该模型对路径方向损失、多屏衍射损耗和阴影增益进行了更精确的预测。实验中采用的地图比例尺是1∶2 000,采用的平均楼层高度为3 m。统计结果表明,该GIS模型预测的路径损耗克服了每个基站的实测路径损耗,在市区可以用来预测微蜂窝覆盖范围。

| Abstract: | The thesis focused on the advantages of GIS in combining spatial and non-spatial database of cellular network to produce necessary parameters that can help predicting cellular network coverage more accurate.The study developed a GIS model for predicting signal coverage of Cityphone mobile network in Hochiminh City,Vietnam based on COST-231-Walfisch-Ikegami model.The model can help determining radio-line-of-sight and non-radio-line-of-sight condition.In addition,in case of non-radio-line-of-sight condition,a... |
