BBU＋RRU分布式基站组网模型探讨

基站基带单元＋射频拉远模块（BBU＋RRU）分布式基站组网因其快速、经济的特点,已成为当前移动网络建设的重要方式之一。随着应用越来越广泛,需要对BBU＋RRU的组网模型进行进一步的探讨,以满足实际应用的需要。本文试根据网络拓扑和设备设置两个方面提出不同的组网模型,给出各种模型适用的建设场景,分析了在实际组网应用中潜在的问题,特别针对组网模型与工程造价之间的关系进行了较为深入的分析,所得出的结论可为建设经济高效的移动网提供参考。

Discussion on Networking Models of BBU + RRU Distributed Base-station

BBU＋RRU distributed networking,for its rapid-building and economic characteristics,has become an important way in mobile network construction.with its wider and widet application,it is necessary to study the networking models of BBU ＋ RRU,thus to meet the needs of practical application.Based on the network topology and device installation,this paper proposes some networking models,discusses their applications and potential problems,and acconding to the practical application scenarios,analyzes the construction cost of these models,thus providing some reference to the construction of cost-effective mobile network.
