摘要：

室内分布系统的建设已经成为解决深度覆盖问题的有效手段。目前，5G网络建设发展迅速，室内分布系统建设呈爆炸式增长，室内分布系统的网络规划和设计需要更加精细化。如何有效评估室内信号覆盖效果，成为当前室内分布系统规划设计的重要任务之一。以某大楼为研究对象，用射线追踪传播模型仿真计算覆盖性能指标，并将结果与现有网络的路测数据进行对比。经过校正相关模型参数实现仿真与实测一致，论证仿真为网络部署提供了参考依据。

Abstract:

The construction of indoor distribution system has become an effective means to solve the problem of deep coverage.At present, 5G network construction is developing rapidly, indoor distribution system construction is exploding, and the network planning and design of indoor distribution system needs to be more refined.How to effectively evaluate the indoor signal coverage effect becomes one of the important tasks of current indoor distribution system planning and design.A building was taken as the research object, the coverage performance index was calculated by ray-tracing propagation model simulation, and the results were compared with the road test data of the existing network.After correcting the relevant model parameters, the simulation is consistent with the actual measurement, and the demonstration simulation provides a reference basis for network deployment.

Key words: indoor distribution system, 5G network, ray tracing propagation model, coverage performance index
