基于微基站的LTE室内场景网络部署方案研究

Research on LTE Small Cell Deployment in Indoor Scenario

由于视频类业务和游戏类业务的迅猛发展,室内数据流量也呈快速增长之势,运营商越来越多的引入室内微基站代替传统室内网络建设方案,用以提升运营效率和网络服务能力。在介绍了3类主流室内网络建设方案——无源分布式天线系统、光纤分布系统和微基站系统的部署特点和问题后,重点分析了微基站在沿街商铺、楼宇、交通枢纽、商业中心、体育场馆和会展中心等典型场景的建筑特点和业务特点,并给出了各场景中的的具体部署方法。

As the rapid business development of video and game industry,the index data traffic also showed a fast growth trend. Operators increasingly introduced small cell instead of traditional indoor network construction solutions to improve the operational efficiency and capability of network service. Firstly,the three types of mainstream indoor network construction solutions-DAS,MDAS and Small Cell are introduced,and their features and problems of deployment are described. Secondly,the architectural features and business characteristics of the typical scenarios that small cell was used are analyzed,such as shops,buildings,transportation hubs,commercial centers,sports venues and convention centers. Finally,the specific deployment methods in each scenario are delivered.
