Wireless Local Area Networks (WLANs) based on IEEE 802.11 are becoming the most widely used WLAN technology for its easy deployment and lower cost. Due to the lack of Quality of Service (QoS) provisioning for integrated services such as voice and data in 802.11, the IEEE 802.11e was proposed. Despite providing service differentiation through priorities, the IEEE 802.11e still failed to meet the strict QoS support for integrated services. We believe Call Admission Control (CAC) being one of the fundamental mechanisms for QoS provisioning, if applied to IEEE 802.11e can further ensure that users get their agreed QoS with acceptable delays for data. In this report we analyze the data performance in IEEE 802.11e with a simplified version new call bounding based CAC scheme using a decomposition approximation. The Decomposition approximation provides a closed form solution if applied to integrated services such as voice and data, and thus easier to compute.
