AT&T CPRI PIM Hunting & Rooftop Antenna Location Testing
Prerequisite: Students must complete the AT&T External PIM Hunting certification course (Combined 1-port & 2-port PIM Hunting using a PIM analyzer) before attending this advanced course. *Cost based on meeting minimum number of course enrollment.
A new CPRI PIM hunting has been developed that uses the site radios to excite PIM sources at cell site while monitoring the uplink receive level using a CPRI analyzer. This process has advantages over PIM hunting using a PIM analyzer in that the PIM sources see the actual site RF illumination vs. simulated levels generated by the PIM analyzer. Technicians can quickly cover objects of concern / make repairs / tap on connections to see if the noise level reduces. With proper training, site PIM problems are often found faster using the new CPRI process vs. using PIM test equipment alone.
A second objective of this training class is to teach students how to evaluate the PIM performance of alternate antenna installation locations on rooftop cell sites. To date, PIM mitigation efforts have focused on fixing the site as designed. In some cases, moving one or more antennas to a new location on the roof may significantly improve performance for much lower cost. The process taught in this class involves deploying temporary antennas at candidate locations and measuring the IM3 and IM7 performance using a 2-port PIM analyzer to evaluate candidate location performance.
