Wireless Local Area Network (WLAN) based on IEEE 802.11e provides Quality of Service (QoS) support at the Medium Access Control (MAC) sublayer. IEEE 802.11e MAC sublayer uses a function called Hybrid Coordination Function (HCF) with Enhanced Distributed Channel Access (EDCA). EDCA is a QoS mechanism that provides a priority scheme by differentiating interframe space and contention window size, it also uses Contention Free Bursting (CFB) scheme that can improve the efficiency of the system. In this study we analyzed performance of wireless network based on IEEE 802.11e in supporting QoS for multimedia transmission. We use three different types of traffic, those are voice, video, and data to analyze the performance of the network in supporting multimedia transmission.
