In this paper, we present a novel scheme that maximizes the number of admissible mobiles while preserving quality of service and resources in wideband CDMAn etworks. We propose the manipulation of two main control instruments in tandem when previous work has focused on handling them separately: transmitter power level and bit rate. The active component of this scheme is the Genetic Algorithm for Mobiles Equilibrium (GAME). The base station measures each mobile received signal quality, bit rate and power. Accordingly, based on an evolutionary computational model, it recommends the calculated optimum power and rate vector to everyone. Meanwhile, a standard closed loop power control command is maintained to facilitate real time implementation. The goal here is to achieve an adequate balance between users. Thereof, each mobile can send its traffic with a suitable power to support it over the different path losses. In the mean time, its battery life is being preserved while limiting the interference seen by neighbors. Consequently, more mobiles can be handled. As ignificant enhancement in cell capacity, signal quality and power level has been noticed through several experiments on combined voice, data and video services.
