基站类型	典型配置	应用场景
宏基站	3扇区，每扇区至少支持20 MHz带宽	主要用于室外大范围宏蜂窝覆盖以及大型建筑物的室内覆盖
微基站	至少支持20 MHz 带宽全向或定向小区	主要用于室外补盲、吸收业务量和中小型建筑物的室内覆盖
微微基站	全向小区，处理能力较低，其带宽可小于20 MHz	分别用于家庭覆盖和室内覆盖补盲

基站产品类型	产品应用场景	引入建议
一体化宏基站	室外大范围宏蜂窝覆盖	具有成熟、稳定、维护方便的优点，但对站址资源要求较高，且天线数较多时安装维护困难，初期部署阶段视站址资源情况部署
分布式宏基站（BBU+RRU）	室外大范围宏蜂窝覆盖或室内覆盖	对站址资源要求低，天线数较多时安装维护较易，整机功率效率高，鉴于初期部署阶段基站天线数较多，考虑大规模部署
一体化微基站	室外补盲或吸收业务量	结合初期热点覆盖情况，考虑后期采用一体化微基站对室外信号盲区进行补盲或进行分层覆盖
分布式微基站（BBU+RRU）	分布式系统室内覆盖或室外补盲覆盖	初期引入分布式微基站（具备MIMO功能）用于重点楼宇室内覆盖
