Passive Intermodulation (PIM) is a growing concern among mobile network operators looking to maximize network capacity, data rate, reliability, and 5G Return on Investment (ROI), while minimizing OPEX. Identifying and mitigating passive intermodulation poses a significant challenge. With the addition of new frequency bands, the probability of getting a third-order intermod falling in your uplink increases dramatically. With heightened build-out and densification activity this increases the risk of new PIM sources. Exploring Challenges, prevention strategies, identification and removal solutions.
