摘要
小型分布式基站Small Cell数量的快速上升对供电方案提出了"零占地"、易部署等新的需求。针对不同的Small Cell基站应用场景,提出了相应的供电解决方案,包括本地交流(AC)供电、本地直流(DC)48 V供电、本地AC和DC 48 V混合供电、DC拉远供电、以太网供电(POE)供电等。此外,还指出了Small Cell基站供电方案的发展趋势,包括:小型化、模块化、高效节能、绿色、共享、智能互联等。
With the rapid growth in number of small cell,new requirements are proposed,such as zero occupation of land and easy deployment.For different application scenes,different power supply solutions are proposed,including local alternating current(AC)power supply,local direct current(DC)48V power supply,local AC and DC48V mixed power supply,DC remote feeding power supply,power over ethernet(POE)power supply,and so on.Moreover,the trends of power supply solutions for small cell are pointed out,including miniaturization,modularized,high efficiency and energy conservation,green,sharing,intelligent and interconnection.
