Blaxian,
How do you observe the interference on the TCH? Are you frequency hopping? What is the size of the hopping pool and how many TRx are in the pool?
Hi, is it shared antenna 2G/3G scenario? If so i suggest you to check for alarms (usually RxLev) on 3G and invetigate for Passive Intermodulation (PIM measurements recommended). hope it helpsbr//
are they located in same geographic area or randomly distributedQuote:
