The IEEE 802.11 family of standards represents the variety of WLAN technique designed for different data rates, spectrum bands and variation in access schemes. In this paper we present an evaluation of the QoS enhancements provided by EDCF medium access scheme, which is adopted in an upcoming IEEE 802.11e standard. Evaluation is made through comparison of EDCF access scheme with DCF medium access scheme defined by legacy IEEE 802.11 standard for WLANs. EDCF provides significant improvements over DCF especially for high priority traffic streams under high load conditions, however these improvements results in worse performances for lower priority traffic.
