Even with two BTS at two TRX (exercising all our four ARFCN), the total call capacity is not more than 13 simultanesous MS-to-MS calls (since each call requires two timeslots). Yes we could do half-rate, but we have no software support for that so far.

You have the adjacent channels 121 to 124 for GSM 900 ? As far as I am aware, adjacent channels will disturb each other. From what I know, real networks usually have one free guard channel in between. So at least the configuration of using adjacent channels should be checked in advance (but you don't know how well different phones behave).
