摘　　要：山区场景地势起伏,海拔高度落差大。山区场景的无线网络规划是否可以使用传统经验模型,还缺少相关验证。本文主要通过在云南某山区进行CW测试,并分析传播模型和模型校正的结果,可以看出传统SPM模型并不适用于山区场景。Mountain scene terrain ups and downs,the altitude changes greatly,from tens of meters to thousands of meters.Whether the traditional empirical model can be used in wireless network planning of mountain scene is still lack of relevant verifi cation.In this paper,CW test is carried out in some mountain area of Yunnan province,and the results of propagation model and model correction are analyzed.It can be seen that the traditional SPM model is not suitable for mountain scenes.

关 键 词：SPM 传播模型校正 山区
