摘　　要： 在多隔断的室内场景中墙体的穿透损耗严重,为保证用户的体验,天线密度相对较高,因此导致有源室分系统的设备价格远高于传统无源室分系统。为降低室分系统的建设造价,提出了一种"有源+无源"的室内覆盖解决方案。通过理论分析及现场测试验证,可以在保证多隔断的室内用户的一定体验效果下,有效降低室分系统造价约70%,在性能与价格中取得平衡。 Since the penetration loss is serious in the indoor scenarios with multi partitions,the antenna density is relatively high to ensure the user experience.Hence the price of the active indoor coverage system is much higher than that of the traditional passive one.In order to reduce the cost of building indoor coverage systems,this paper proposes an"active+passive"indoor coverage solution.Through theoretical analysis and field test,the proposed solution effectively reduces the cost by about 70%while ensuring a certain experience of indoor users with multiple partitions,and thus achieves a balance between performance and price.
