Abstract
A method of providing Quality of Service (QoS) in a wireless LAN system, wherein plural stations comprise the wireless LAN network, and wherein the wireless LAN network includes a protocol providing for contention periods and contention free periods, includes grouping the stations into a polling list set; selecting a number of the grouped stations for inclusion in a polling list subset, wherein preference is given to high-priority QoS stations in the polling list subset; and polling the high priority stations during a contention free period.
