| 摘 要： | 在自由空间电波传播损耗模型基础上,根据微小区内电波传播特点,提出了电波传播损耗的一般预测模型,其特点是用最小拐点距离D来统一反映天线高度和系统工作频率对电波传播损耗的影响,同时对电波在传播过程中经过的不同环境,分别用不同的路径衰减指数n来反映.

| Abstract: | Based on the radio wave propagation loss model in free space and the characteristics of radio wave propagation in microcell,this paper proposes the generalized predicting model of radio wave propagation loss,whose key points are to use the minimum inflection point distance to reflect unitedly the influences of antenna height and system frequency and the path attenuation exponential is used to reflect the varying surroundings in the radio wave propagation path. |

| Keywords: | radio wave propagation loss minimum inflection point distance path attenuation exponential |
