  • SYSTEMS AND METHODS FOR ACTIVE CELLULAR TRANSCEIVER ANALYSIS FOR HARMFUL PASSIVE INTERMODULATION DETECTION
    Publication number: 20150087242
    Abstract: Described herein is a system and method for detecting intermodulation distortion (IMD), such as passive intermodulation (PIM) signals, that are being generated by an active cellular transceiver. One such system may include a diagnostic module that detects signals emitted by an active cellular transceiver that has at least two active signals. The detected frequencies of the active signals are compared against potential PIM frequencies to identify potential PIM signals, and the results of this comparison will be analyzed statistically to generate a confidence value in the identification of potential PIM signals.
