PIM & RTWP Mitigation
When elevated RTWP is coming from the site itself rather than the RF environment, the fault is in the antenna line, the connectors, the grounding or the radio. We isolate it, correct it and validate the result with sweep data.
Passive intermodulation rarely announces itself. It shows up as an uplink noise floor that will not come down, worse under load, sometimes worse in the wet — and it is often chased as external interference for weeks before anyone puts a PIM analyser on the line.
