Measurements on mobile network antennas - Part 5 - PIM 
This series explains measurements on mobile network antennas. 
In this fifth part of the video series, effects of Passive Intermodulation (PIM) are discussed. I'm showing measurement methods, influences on the eNodeB, the impact on customers and the avoidance of PIM. In addition, I explain in detail the influence of PIM on different mobile radio bands and antenna interconnections of mobile providers and I present a calculation method for PIM. In-house systems and repeaters are also discussed.
