Generally, the rate of reuse should be increased within the certain area for efficient operation of radio resources in a CDMA mobile communication system, and then signal interference between the same radio channels should be minimized. For this reason, this study conducted a simulation of cell secterization methods(3 and 4 sectors) as a practical and immediately applicable method to the field to minimize signal interference, to construct an economical network, and to increase the efficiency of frequency use. Also, by analyzing RSSi, Ec/Io, Eb/Nt, and 3-way handoff which were simulation results, their possibility of use was identified.
