Abstract: IEEE 802.16 WiMAX network is designed for providing high speed wide area broadband wireless access. WiMAX is an emerging wireless technology which is used for creating multi-hop mesh networks offering variable and high data rates, QoS, seamless mobility within a network. OPNET modeler is a simulation program tool used to simulate the different types of wireless networks. In this paper, simulation and evaluation of three different sized networks (small, medium, large) is carried out. We are using the modeler to study networks with 15, 25 and 40 mobile workstations. In each network, group of five WiMAX workstations connect and call each other through one WiMAX base stations during 1000sec. Performance of parameters that indicate the quality of services such as initial ranging activity, delay, total transmission power and PHY path loss have been studied
