WiMAX deployments not only serve residential and business users, but can also be deployed as a backhaul for Wi-Fi hotspots and cell towers. By providing affordable wireless broadband access, WiMAX technology will revolutionize broadband communications in developed countries and bridge the digital divide between WiMAX and Wi-Fi. First, it will discuss the performance analysis of WiMAX. compared to Wi-Fi. Second. Advances in Computing – Secure Software and Related Issues. Department of Computer Science, College of Computer Science and Information Technology, Taif University, PO Mobile Wi-Fi WiMAX uses orthogonal multiple frequency distribution. For our delay analysis, we considered transmission, processing, and queuing delays at network nodes. The analysis during IMS signaling procedures in WiFi and WiMax networks will enable industry researchers to implement IMS using SIP in a real-time WiFi and WiMax environment. We define the transfer delay as a difference between an audio signal segment and an audio signal segment used to analyze the performance of Wimax-based systems. The transmitted audio message was found to have been retrieved effectively in a noisy situation. Show full text
