I think what Bhupendra asked was how many TRX’s can be deployed per sector depending on the 22 ARFCN NOT the BTS Capacity. He’s worried of TIGHT frequency. In my case i work for an operator with 24 GSM 900 ARFCN and we are using maximum of 2 TRX’s per sector. We have many DCS Frequency where we use 6 TRX’s.
