• In order to utilize the frquency resource adequately and increase the capacity of mobile communication system , the wireless electric wave propagation of existing mobile system always adopts the microcell structure . forecasting the path loss characteristic of electric wave accurately can provide the necessary condition for the layout and design of wireless network , at the same time it is a precondition for the research on the microcell mobile system . the methods of forecasting of wireless electric wave propagation can divide into two parts : one is pluse and respond , that is establish the empirical model based on experimental and statistical data ; the other is ray tracing method , that is establish the deterministic model based on theoretical analyse . the paper discuss the characteristic of wireless signal electric wave transmition in symmetrical atmosphere of earth , and introduce the common path loss transmition model in land mobile communication system , also point out the localization of these models based on experiential methods
  而精确预测无线电波传播路径损耗特性，则为合理的微蜂窝无线网络规划、设计提供了必要条件，同时也是研究微蜂窝移动通信系统性能的前提。无线电波传播预测的方法分为两类：一是用冲激响应法，即根据实验、统计所得数据建立经验性传播预测模型；另一种是用射线跟踪方法，即依据理论分析来建立确定性的传播预测模型。本文首先讨论了在地球表面均匀大气中的无线电波传播的基本特性，介绍了陆地移动通信系统中常用的几种电波传播路径损耗经验性预测模型，并指出了这些经验性传播模型对于微蜂窝小区无线电波传播特性研究的局限性。
