Five different service classes are supported in mobile WiMAX IEEE 802.16 standard in order different needs of the mobile users to be fulfilled. In this paper we analyze the impact of the propagation environments on the WiMAX service classes and we measure the QoS performances of the service classes that are utilized from the mobile users. Simulation experiments are done utilizing the ns-2.33 simulator where all five service classes of the WiMAX are properly configured. Performances analysis of the service classes in mobile WiMAx is done measuring the average throughput, average delay and average jitter in various propagation environments. Obtained results give important conclusions about the QoS of the five service classes in mobile WiMAX in various propagation environments.
