I am also interested in this stuff.
EDCF is the enhanced DCF, which is discussed by IEEE 802.11 Task Group =
E. The aim of the Task Group E is to enhance the MAC layer QoS. =
Generally speaking, the access parameters (CW, IFS, TXOP and etc) are =
differentiated to provide QoS support to 802.11 WLANs.

For more information, refer to http://ieee802.org/11
