Actually, the cellular companies cause high PIM to themselves, in certain circumstances. It has become more necessary to reduce the effects of high PIM readings, as the new frequencies and higher data requirements have been deployed. While installing 4G radios for Verizon Wireless, the requirements changed and the use of PPC crimp connectors were mandated, as were PIM testing all polyphaser to radio jumpers. Site installation times went from about 6 hours to 9 hours, in light of the new requirements, but I got to charge a lot more money for the installations. J

So I looked it to make sure I understood his concerns. For you gents sharing space with Cellco or Two way radio operators on site, this can perhaps shed some light to what can cause you headaches. http://www.anritsu.com/en-US/Products-Solutions/Solution/Understanding-PIM.aspx Jaime Solorza Wireless Systems Architect 915-861-1390
