UMTS系统干扰分析与排查

Analysis and Troubleshooting of UMTS System

联通UMTS网络随着网络的逐步建设,UMTS900、UMTS2100网络普遍出现在广大的农村区域和城区,RTWP的抬升使得网络的性能大幅下降,致使覆盖降低、掉话增加、用户感知降低。因此,干扰的严重程度关乎外来干扰电平的高低以及接收机灵敏度损失情况,RTWP干扰排查在维护整个UMTS网络稳定中占据很重要的地位。

Unicom UMTS network with the gradual construction of the network,UMTS900 network,UMTS2100 generally appear in the vast rural areas and urban areas,RTWP uplift makes the network performance decline,resulting in decreased coverage,drop increase,reduce the user perceived.Therefore,the severity of interference is related to the level of external interference level and receiver sensitivity loss.RTWP interference detection plays an important role in maintaining the stability of the entire UMTS networ k.
