文章介绍一种预测高楼中某一楼层路径损耗和电波有效覆盖范围的混合模型。该模型结合二维射线追踪法和“直折射”模型,并考虑金属物体的影响,可明显提高预测的准确度。
This paper presents a hybrid model that predicts the path loss and effective coverage of a given floor in a tall building. Combining the two-dimensional ray-tracing method with the “straight-refraction” model and considering the influence of metal objects, the model can significantly improve the prediction accuracy.
