December 1, 1901 Discover the science behind passive intermodulationDiscover the science behind passive intermodulation
Also known as the “rusty bolt effect,” passive intermodulation (PIM) is a serious issue in the wireless industry, and one that has been growing over time. Constant installation of new equipment along with higher density of modulation symbols compound into difficulties caused by PIM. Explore the science of PIM to take a closer look and discover why it matters, and what you can do to address it.
