Interference can impact 4G and 5G performance

PIM and RF interference pose significant challenges within wireless networks, jeopardizing signal quality, network capacity and ultimately subscriber quality of experience. To avoid negative impacts on network performance, interference issues must be solved quickly. However, identifying the root cause of these issues, then mitigating them, can be a very costly, manual and time-consuming process-and at odds with the pressure to troubleshoot cell sites on time and on budget.

What to consider when diagnosing RF interference and PIM

icon loop

Hard to identify whether PIM is internal or external to antenna systems

icon chrono

Technicians have a short window to troubleshoot and solve issues

icon tower

Costly tower climbs don't guarantee issue resolution

icon warning

Difficult and unsafe to carry a bulky, heavy PIM analyzer up the tower

icon training

Using various complex test tools with different interfaces requires extensive training

How-to videos and webinar

Identifying PIM in the field

Ride along with a field technician to see how he uses a best-practice methodology to investigate the performance degradation of a cell site.

Locating and mitigating PIM

Learn how to quickly locate a PIM source and launch a mitigation strategy to address PIM across a cell site.

Detecting and mitigating PIM

We joined forces with ConcealFab, Inc. and Kaelus for a webinar about efficient strategies to identify and mitigate PIM for improved cell-site performance.
