If two or more cells with the same frequency and same PCI are geographically adjacent to each other, the signals in the overlapping area between the cells will interfere with each other, and the UE cannot correctly demodulate the signal in the overlapping area, resulting in an increase in the call drop rate on the existing network. High, the PCI conflict in this case is called which of the following?
