摘　　要：为了能快速预测宏小区环境的无线覆盖情况,给初期的网络规划提供一个较为准确的参考依据,本文采用双射线模型对宏小区场景下的传输损耗进行了估算。首先给出了电磁波在自由空间中的传播理论,在此基础上分析了不同频率下双射线模型路径损耗随传播距离的变化。本文的目的是针对宏小区环境建立起一种快速和较为准确的无线覆盖预测参考模型。In order to predict the wireless coverage in macro cell environment quickly and provide an accurate reference for the initial network planning,the path loss is estimated by the two-ray tracing model.First the theory of electromagnetic wave transmitting in free space is introduced.Based on this,the path loss changing with the propagation distance of two-ray tracing model at different frequencies is analyzed.The aim of this paper is to establish a fast and accurate prediction model of wireless coverage for macro cell environment.
