摘要：Due to fast development of technology, future communication and transmission are totally depends upon wireless network. Wireless networks are generally less efficient and irregular compared to wired networks, which make quality of service (QoS) provision a bigger challenge for wireless communications. The wireless medium has limited bandwidth, higher packet error rate, and higher packet overheads that in total to limit the capacity of the network to offer guaranteed QoS. In response to the increasing QoS challenge in wireless networks, researchers have made significant modifications in Wireless Fidelity (WiFi) in the legac y IEEE 802.11 standards to make possible QoS to end users. The design constraints at several layers of the IEEE 802.11 restrict its capacity to deliver guaranteed QoS. Recently, the IEEE 802.16 standard, also known as worldwide interoperability for microwave access (WiMAX), has emerged as the strongest contender for broadband wireless technology with promises to give guaranteed QoS to wireless application end users over wifi wireless technology. This paper tries to explain the architectural performance issues of WiMax over WiFi wireless communication in the term of wireless network design and management which upgrading the upcoming wireless communication technology over a wide region
