- 20. I International Workshop on Challenges and Trends Beyond LTE-A What is Passive Intermodulation (PIM) TX signals at site Passive Intermodulation (PIM) F1 F2 Passive Intermodulation (PIM) IM 3 IM 3 IM 5 IM 5 IM 7 IM 7 IM 9 IM 9 • PIM = interference • PIM = new frequencies generated by Tx signals at a cell site when they encounter “non-linear” junctions in the RF path • PIM falling in an operator’s uplink can elevate the noise floor: ▪ Dropped calls ▪ Access failures ▪ Slower data rates
- 21. I International Workshop on Challenges and Trends Beyond LTE-A What is non-linear at a cell site? • Loose metal-to-metal contacts – Poorly terminated RF connectors – Metal flakes inside connectors – Loose RF connectors – Metal flashing on rooftops – Loose rivets, screws, etc. • Rusty / corroded surfaces • Non-linear materials – Nickel / Steel – Ferrite Nov-13
