Abstract :
It is shown that radio capacity can be increased 2.33 times if a selective zone approach is used, and 1.75 times if a nonselective zone approach is used. The efficiency of using the microcell configuration reaches a maximum because K=3 is the smallest number of cells in a frequency reuse system. When applying the analog system with a nonselective zone configuration, the radio capacity can be increased by 1.75 times. When applying microcells to CDMA systems, the nonselective-zone configuration can be used to further reduce the interference
