基于ATOLL的无线传播模型校正及其验证研究

Calibration and Verification of Wireless Propagation Model Based on ATOLL

准确的无线传播模型不仅有利于网络规划、评估网络性能,更有利于后期网络调优、提高网络质量。通过南方某地(市)的模型校正案例说明传播模型的校正过程,主要包括测试准备、数据采集、数据处理和模型校正4个阶段,并通过同城同场景和异城同场景交叉验证模型的有效性和可靠性,为网络规划和建设提供重要依据和支撑。

An accurate wireless propagation model is not only beneficial to network planning and network performance evaluation,but also to network tuning and network quality improvement.A model calibration case of a southern city is used to illustrate the calibration process of the communication model,which mainly includes four stages:test preparation,data acquisition,data processing and model calibration.The validity and reliability of the model is verified through cross-verification of the same scene in the same city and the same scene in the different city,which provides important basis and support for network planning and construction.
