Passive Intermodulation (PIM) is not a new phenomenon. However with the introduction of site sharing with multiple transmit carriers and use of multi-technology sites (GSM, UMTS, CDMA and LTE) by several operators, PIM issues are getting more serious and more complex. This presentation gives a full overview off the fundamentals, problems, solutions and testing techniques to improve the radio access network performance.
