C-RAN实现无线网精准投资

C-RAN for Precision Investment of Wireless Network

由于移动通信网存在话务潮汐效应,在2G/3G/4G时代,为了满足各小区忙时的话务需求,无线网络利用率普遍偏低,存在投资浪费现象。5G将采用大量的新技术,包括密集异构组网UDN、C-RAN、SDN/NFV、大规模MIMO等,随着CRAN技术的实现,无线网络的话务潮汐效应导致的基站设备额外需求将大幅下降,从而实现按需配置、精准投资,大幅降低网络建设和运营成本。

Due to the tidal effect of mobile communication network,in the 2G/3G/4G era,in order to meet the busy demands of each cell,the utilization rate of wireless network is generally low,which is a waste of investment.5G will adopt a large number of new technologies,including dense heterogeneous networking UDN,C-RAN,SDN/NFV,large scale MIMO and so on.With the implementation of C-RAN and other technologies,the additional demand for base station equipment due to the tidal effect of wireless network will be greatly reduced,thus realizing on-demand configuration,precision investment,and greatly reducing the construction and operation of the network.
