【摘要】：随着4G网络的商用,室分场景下多运营商多系统合路的情况越来越多,以广西体育中心场馆分布系统建设期间出现UMTS室分系统底噪异常的情况为例,对室分UMTS系统(2 100 MHz频段)与移动TDD-LTE系统(2 300 MHz频段)合路后出现了三阶互调干扰的问题展开研究,找到了解决办法,并为类似场景的室分建设提出了规划建议。
[Abstract]:With the use of 4G network , the multi - operator multi - system approach is more and more complicated . In case of the abnormal noise of the UMTS system during the construction of the venue distribution system in Guangxi Sports Center , the problem of third - order intermodulation interference appeared after the system ( 2 100 MHz frequency band ) and the mobile TDD - LTE system ( 300 MHz frequency band ) were closed . The solution was found , and the planning suggestion was put forward for the construction of similar scenes .
