摘　　要：700 MHz频段曾经为广电专用网络,国内通信业对该频段传播特性研究较少。网络规划需要精准的传播模型,传播模型对于站间距的合理设计和网络性能的准确仿真有决定性作用,必须对传播模型开展校正和数据分析,以支撑700 MHz无线网规划工作。本文基于SPM模型,通过对700 MHz传播模型校正过程的分析和统计处理,最终得出700 MHz传播模型和相关指标参数,为700 MHz系统落地提供参考。In the early stage,700 MHz band was a special radio and television network,but the domestic communication industry had little research on the propagation characteristics of this band.Network planning needs accurate propagation model.Propagation model plays a decisive role in the reasonable design of station spacing and accurate simulation of network performance.It is necessary to carry out correction and data analysis on propagation model to support 700 MHz wireless network planning.Based on SPM model,through the analysis and statistical processing of the calibration process of 700 MHz propagation model,the 700 MHz propagation model and related index parameters are finally obtained,which provides a reference for the implementation of 700 MHz system.

关 键 词：700 MHz规划 SPM模型 传播模型校正
