  • Description: M.Tech. (Electrical Engineering) , Abstract: Wireless communication has been part of communication for decades and continues to evolve in a radical manner. These days communication cannot be separated with various technologies and newly developed devices tend to be integrated to support wireless. WiMAX is a wireless industry coalition and is part of the latest wireless infrastructure which includes 3G and LTE and needs to supports both communication and other technologies. WiMAX is seen as WiFi that supports greater distances of up to about 50 kms in radius. In this study we simulate the WiMAX performance - simulations are done using OPNET, NS-3 and Markov Chains are also used to evaluate the performance and compare the results. The study looks at the delay and the throughput in the WiMAX network as we increase numbers of connected devices from 20 to 50, 75 and lastly 100 mobile devices. The results of these performance indicators were analyzed and OPNET was found to be the best simulation tool amongst the three that was user friendly and easy to work with, which also returned results that are satisfactory and resembles reality.
