Station EDCA Parameters
Queue	Specifies the four ingress queues:
	Data 0 (Voice) - High priority queue, with
	minimum delay. The queue is used to
	store time-sensitive data, such as VOIP
	and streaming media.
	Data 1 (Video): High priority queue, with
	minimum delay. The queue is used to
	store time-sensitive data, such as video
	traffic.
	Data 2 (best effort): Medium priority
	queue, with minimum throughput and
	delay. The queue is used to store most
	traditional IP data.
	Data 3 (Background): Lowest priority
	queue, with high throughput. This queue
	is used for bulk data that requires
	maximum throughput and is not time-
	sensitive, such as FTP packets.
AIFS (InterFrame Space)	Specifies the Arbitration Inter-Frame
	Spacing (AIFS) value, which controls the
	wait time for data frames. The wait time is
	measured in slots and has a range of 1 to
	15 slots.
cwMin (Minimum	Specifies a value that an algorithm uses to
Contention Window)	determine the initial random backoff wait
	time (window) for resending packets
	during a period of contention for Unified
	Access Point resources.
	This value is the upper limit (in
	milliseconds) of a range from which the
	access point determines the initial random
	backoff wait time.
