hi pix,
i just that MR sammi is talking about call drops due ti control channels.ok u r right.but..u r saying about interferance i think it can be prob but it is not exactly like that.when we plan a cell and give frequency to that .adjacent channel interfarence is already removed .it may be co-channel interferance.but i think it is not like that.the prob is there configuration in TRX frequency in BTS card.he should that configaration.i think then he will be right.
bye
