5G数字室分设备成本分析

Equipment cost analysis of 5G digital indoor systems

在5G时代,DAS分布系统无法有效满足业务变化对室内覆盖的要求,数字室分成为优选方案。然而,数字室分成本问题突出。其中,设备成本过高的问题在4G时代已经显现。文章重点结合数字室分的结构特点,提出模型化分析方法,分析数字室分设备成本的组成规律,为实现高性价比的5G室内方案提供保证,达到高效建设的目的。

With the arrival of 5G era, distributed antenna systems(DAS) can not effectively meet the requirements of indoor use cases. Digital Indoor Systems(DIS) becomes the preferred scheme. However, the high cost of digital room has become a big problem. Especially the equipment cost is too high, which is already known in 4G network. In this paper, a cost analysis method is proposed by building a model. With the composition law of equipment cost, we get a better way to achieve at lower costs in DIS.
