室内覆盖基站中拉远有源设备供电方式的研究

Research on the Remote Active Device's Power Supply of in-Door Coverage Base Station

随着中国城市化进程快速推进,城市中高层住宅小区、商务写字楼、商务酒店等高大密集建筑物雨后春笋般的崛起,为解决高大建筑物中众多用户的通信需求,运营商越来越关注室内覆盖基站的建设。随着分布式基站的推广,WLAN网络的逐步解禁,加之高大建筑的固有特点,在室内覆盖基站建设中出现了越来越多的拉远有源设备。拉远有源设备的可靠稳定工作,决定了室内覆盖的效果和用户体验。文中就室内覆盖基站中拉远有源设备的可靠性供电方式进行探讨,以期能为后期的室内覆盖基站建设提供参考。

At present,with the rapid development of China＇s urbanization process,many tall dense buildings such as mid-high rise residential areas,business offices and commercial hotels are appearing quickly.So telecommunication operators pay more and more attention to the construction of in-door coverage base station to solve many customers＇ demand in high buildings.With the promotion of the distributed base station,the gradual lifting of the ban for WLAN net and the inherent characteristics of tall building,there are more and more remote active devices in indoor coverage base station.The effects of indoor coverage and user experiences are determined by the reliable and stable work of this station.This paper gives several methods for reliability power supply of remote active devices,and analyzes its advantages and disadvantages,hoping to help later in-door coverage base station construction.
