摘　　要：传播模型是无线网络规划和优化的基础,每一个模型反映了特定地区的电波传播特性,由于各个地区,各个不同的城市,其地物地貌有着很大的不同,需要建立适合当地特点的模型来指导网络规划和优化工作,无线传播模型校正必须在通用传播模型的基础上根据合理的测试数据和物理数据,关注模型校正中可能出现的误差,合理设置参数,最终形成适合当地无线传播环境的传播模型。Propagation model is the foundation of wireless network planning and optimization,each model reflects the propagation properties of radio waves in specific areas,because each region,different cities,the residential physiognomy are quite different,need to establish the model of local characteristics for guiding the wireless network planning and optimization in general the propagation model must be based on the test data,and according to the reasonable physical data model and focus of possible error correction,reasonable parameters,and form the final propagation model which can match the environment of local wireless communication.
