MIMO技术在5G室分场景的应用与移频MIMO改造

Application of MIMO Technology in 5G Room Scene and Frequency Shift MIMO Transformation

从室内覆盖系统中多输入多输出(Multiple Input Multiple Output,MIMO)的适用场景和覆盖规划要点入手,基于仿真过程分析MIMO室内覆盖信道的容量特点。为了满足5G室分覆盖需求,选出2处场景进行移频MIMO改造。方案改造后,分析现场检测所得的上下行速率等数据,证明了移频MIMO改造方案不仅有较好的经济性,还能满足室内覆盖需求。

Starting from the application scenario and key points of coverage planning of the Multiple Input Multiple Output(MIMO)indoor coverage system,the capacity characteristics of the MIMO indoor coverage channel are analyzed based on the simulation process.In order to meet the needs of 5G room coverage,two scenes are selected for frequency shift MIMO transformation.After modification of the scheme,the data of upstream and downstream speed obtained from field detection are analyzed,which proves that the modification scheme of frequency shift MIMO not only has good economy,but also can meet the requirements of indoor coverage.
