摘　　要：在第五代移动通信时代,室内场景依然是移动数据产生的主力区域,高频段的频谱资源能够提供更大的带宽,但穿透损耗和传播损耗也较2G~4G通信更大,5G信号在传播过程中受建筑材料、办公家具分布等因素的影响更大,因此通过室外站对室内进行信号覆盖的建网策略,达不到室内的深度覆盖需求,要进一步单独对室内进行5G网络部署。文章通过分析经典的室内传播模型,并在现场对传播损耗和穿透损耗进行测量,结合实测数据对传播模型进行系数修正,使传播模型能够指导室内网络部署。In the fifth generation mobile communication era,indoor scenes are still the main areas of mobile data generation,the spectrum resources of high frequency section can provide greater bandwidth,however the penetration loss and transmission loss are also larger than 2G~4G communication.5G signal is more affected by the distribution of building materials and office furniture during the transmission process.Therefore,the network construction strategy of indoor signal coverage through outdoor station can not meet the indoor deep coverage requirements,5G network deployment should be carried out separately in the room.This paper analyzes the classical indoor communication model,measures the transmission loss and penetration loss on the spot,and corrects the propagation model coefficient with the measured data,so that the communication model can guide the indoor network deployment.
