GIS在移动蜂窝网络规划中有重要应用,本文旨在研究以最低的投资和维护费用,确定GIS最佳解决方案用以改善蜂窝网络的传播质量。本文利用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,提供必要的参数,更准确地预测蜂窝网络的覆盖范围。本文研究对象为越南胡志明市的部分区域,实验成功开发出预测移动蜂窝网络覆盖范围的基础地理信息系统模型,实现了预测信号强度的可视化,分析了场强覆盖范围,并显示了研究区域中每个小区站的可能切换区域。实验结果表明,GIS模型在移动通信尤其对小区站覆盖范围预测是非常有用的。
GIS has an important application in mobile cellular network planning. This paper aims to study how to determine the best GIS solution to improve the quality of cellular network transmission with the lowest investment and maintenance costs. In this paper, we use the advantage that GIS can combine the spatial and non-spatial data in the cellular network database to provide the necessary parameters to predict the coverage of the cellular network more accurately. The research object of this paper is a part of Ho Chi Minh City in Vietnam. Experiments successfully developed a basic geographic information system model for predicting the coverage area of mobile cellular networks, visualized the predicted signal strength, analyzed the coverage of field strength, Possible cell area switching area. The experimental results show that the GIS model is very useful in mobile communication especially for the coverage of cell sites.
