Dear All,
BCCH and BSIC pair together can cause co BCCH/BSIC clash and Ghost RACH but independently two same BSIC’s do not harm the network.
Same BCCH causes interference with the same BSIC the system cannot recognize which cell it is.
@ Naseer: If there is no overlapping of these cells then there will be no issue at all till the time they are not added as the neighbor of each other. If they are added as the neighbor then system will again not recognize to which cell it should handover to because HO is based on BCCH and BSIC pair not on the Cell ID.
