Enhanced Distributed Channel Access (EDCA) is used for transmitting good quality of service of multimedia traffic in Wireless Local Area Network (WLAN). Applications like Constant Bit Rate (CBR), File Transfer Protocol (FTP) and Voice over Internet Protocol (VoIP) are used in wireless LAN network. Audio data is assign as high priority (AC-VO) and other such as CBR & FTP type of data are assigned as low priority (AC-BE) in IEEE 802.11b network. G.711 provides a very good perceived audio quality in comparison to other audio CODECs.
