摘要
移动通信的LTE时代已经全面开启。在进入LTE阶段后,BBU的集中部署可以降低基站选址难度、减小建设和维护成本并实现快速建网,因此呈现了规模应用的态势。从BBU集中部署后CPRI链路的承载需求入手,对多种可能的承载方案进行了比较分析,并结合实际测试结果提出了应用建议。
LTE of mobile communications has been fully opened. In the stage of LTE, BBU＇s centralized deployment can effectively reduce the difficulty of development for base station sites, lower down CAPEX/OPEX and achieve rapid network construction, thus rendering large-scale application of the situation. Firstly, the requirement of CPRI link for BBU centralized deployment was introduced. Secondly, several possible solutions for carrying CPRI link were described. Finally, the application recommendations through comparison and analysis were presented.
