Quality of Service is an essential parameter to judge performance of any Network. WiMAX supports various multimedia applications like VoIP, IPTV and online gaming. The IEEE 802.16 technology (WiMAX) is a better alternative to 3G or wireless LAN networks for providing last mile connectivity by radio link due to its high data rates, low cost of deployment and large coverage area and Ease of Use. With the IEEE 802.16e-2005 mobility amendment, WiMAX promises to address the ever-increasing demand for mobile high speed wireless data in fourth-generation (4G) networks. WiMAX market studies continue to project increased subscriber growth rates and planned carrier trials worldwide. Coupled with these increasing growth rates and higher WiMAX throughput rates, bandwidth intensive video on demand (VoD), Internet Protocol TV (IPTV), and mobile TV services are emerging in the forefront of the mobile arena. Our paper focuses on analyzing QoS parameters through OPNET Modeler that affects on IPTV and IPTV over WiMAX such as Packet delay variation, ,Packet end to end delay, traffic sent (packets/sec) and traffic received (packet/sec) according to coverage area and number of IPTV connections.
