External Passive Intermodulation (PIM) is becoming a major threat to LTE and 5G network performance, often caused by loose hardware, vibration, and metal-to-metal contact near the RF path. Modern sites need next-generation external PIM mitigation to maintain signal integrity and reduce interference. FIMO’s PIM Shield® offers a low-PIM, non-metallic mounting system that eliminates PIM at the source—improving 5G reliability, throughput, and coverage. A simple, cost-effective way to future-proof your RF infrastructure.

Continuous Wave (CW) PIM testing is reshaping how field teams diagnose and prevent network performance issues. Unlike pulse-based methods, Rosenberger’s CW PIM Site Analyzer delivers uninterrupted power to reveal even the smallest faults under true BTS operating conditions. With plug-and-play filter units, unmatched distance-to-fault accuracy, and support for next-generation bands, CW testing is becoming essential for 5G-ready, high-reliability sites.
