Supporting as much Voice over IP (VoIP) users as possible in a BWA network using limited radio resources is a very important issue. However, performance of VoIP services is affected by several issues defined in the IEEE 802.16e protocol. In this paper, the authors used a theoretical model and an algorithm to evaluate the performance of some of the most important VoIP codecs. Simulation results validate the theoretical model to achieve the maximum number of VoIP streams for different configurations of the IEEE 802.16e system.
