Passive Intermodulation (PIM) as a source of 4G/LTE interference

Posted on

Passive Intermodulation (PIM) as a source of 4G/LTE interference What is PIM? One cause of self-disturbance in LTE Networks is Passive Intermodulation (PIM). PIM is interference resulting from the nonlinear mixing of two or more frequencies in a passive circuit. If the interference coincides with a network’s base receive frequencies, it can cripple network performance and throughput. Possible PIM […]
