Abstract
A wireless local area network (WLAN) supporting real-time application (RTA) packets that are sensitive to communication delays as well as non-real time packets over a network supporting carrier sense multiple access/collision avoidance (CSMA/CA) using enhanced distributed channel access (EDCA) in an EDCA queue system. At least one new access class (AC) and associated transmit queue for enqueuing RTA packets while non-RTA packets are enqueued to the original transmit queues in the EDCA queue system. A new EDCA function (EDCAF) is created for the new access class (AC) transmit queue for RTA packets in which the RTA queue is able to contend for channel before expected RTA packets arrival.
