Wireless access networks are developing at a very rapid rate. They are convenient in providing Internet access in remote inaccessible areas thatconfront for traditional wireline service providers. Wireless communication provideslesser cost, wider support for massive users and conveniently accessible fordifferent users but on the other hand these are considered less efficient and irregular as compared to the wired networks that make end-to-end quality of service (QOS) provision a challenge for wireless networks.Wireless access networks are widely accepted and continuously advancing by expanding their coverage, bandwidth and QOS services. Commonly used wireless standards are IEEE 802.11 (Wi-Fi) and IEEE 802.16 (WiMAX). IEEE 802.11 (Wi-Fi) is a standard that provides high speed WLAN connectivity such as in buildings, homes, hotels, cafes and airports. Wi-Fi networks are possibly the most widely used and accepted technology by providing the highest transmission rate among standard wireless networking.IEEE 802.16 (WiMAX) is a standard to provide high speed transmission in both indoor and outdoor environments.Moreover, it is innovative and commercially viable alternative in last mile implementations to cable modems, DSL technologies and T1/E1 cables. This paper provides detailed technical differences between the 802.11 and 802.16 and also discusses the QOS Service classes of WiMAX network. The simulation consequenceshave been beholding with network simulator allinone-3 and investigating the performances of the overall network
