Abstract

Disclosed are a passive intermodulation position detection method and device. The method comprises: transmitting a passive intermodulation test signal and collecting a passive intermodulation signal; and, determining a correlation between the size of a passive intermodulation and the position thereof on the basis of a time relation between the passive intermodulation signal and the passive intermodulation test signal. By means of the technical solution of the present invention, fault maintenance and detection costs are reduced, the speed of delivery is increased, the efficiency of fault diagnosis is increased, self-diagnose function of the device is implemented, and network quality and customer satisfaction are increased.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a passive intermodulation position detection method and device. Background technique [0002] In wireless communication systems, it often occurs that the receiving noise floor is raised, resulting in a decline in receiving performance. A large part of it is due to the poor passive intermodulation index of the antenna feeder system, and the intermodulation products of the transmitted signal just fall. Into the receiving signal band, resulting in the increase of the receiving noise floor, affecting the receiving index, and then leading to the deterioration of the Key Performance Indicator (KPI) of the wireless network, such as shrinking coverage, increasing call drop rate, and handover success rate Degradation, etc., will eventually affect the network quality, cause customer complaints, and seriously affect customer satisfaction. [0003] The problems of the antenna feeder syst...
