摘要
在LTE基站中,天馈老化、跳线接头氧化等原因常导致互调干扰产生,严重的互调干扰使得基站服务能力下降,出现覆盖范围缩小、掉话率提高、切换成功率降低等问题,严重影响用户感知。建议针对基站互调干扰的成因、现象和影响进行重点剖析和研究,并针对互调仪价格贵、不易携、需上站操作等缺点,提出一种新的互调干扰定位方法,利用该方法可远程快速定位问题通道。
In LTE base stations,the aging of the antenna feeder,jumper connector oxidation and other reasons often lead to intermodulation interference.Serious intermodulation interference makes the base station service capability reduction happen,the coverage range,call drop rate,switching success rate is reduced,seriously affecting user perception.In this paper,we focus on the causes,phenomena and effects of BTS intermodulation interference,and propose a new intermodulation interference localization method for the shortcomings of the intermodulator,such as expensive,not easy to carry,and need to operate on the station,which can quickly locate the problem channel remotely.
