Reply To: Why not use different tilt for each ant.


Well in terms of coverage it might be ok. but the problem is that BCCH is sensed to setup a call and then it is assigned to any of the TRXs and your coverage would be discribed by the tilt of the BCCH for all practical reasons for setting up calls / handing over. now if other TRXs are connected to different tilt antennas then when BCCH levels are good at a point and allocated a call to another TRX its Levels might not be good so. call failures and drops would result ..better approach would be to have coolocated cells with different tilts and different frequencies like DCS having overage of closer calls down tilted and GSM taking far away calls .. not downtilted..
