Cellular network operators must periodically upgrade their networks by installing new base stations in order to accommodate traffic growth. In the study discussed in this paper, an optimization model is developed to determine an optimal location for deploying a new base station in an overloaded, single-macrocell CDMA system. The optimization model explicitly considers inter-cell interference and accounts for both path gain-based terminal-to-base assignments as well as optimal assignments that minimize interference and thereby maximize total system capacity. The results demonstrate that for both assignments schemes, several base station locations may support the maximum capacity when the two-cell system is underloaded.
