Description

Queue	Queues are defined for different types of data transmitted from the client sta-
	tion to the access point:
	Data 0 (Voice)
	Highest priority queue, minimum delay. Time-sensitive data such as VoIP and
	streaming media are automatically sent to this queue.
	Data 1(Video)
	Highest priority queue, minimum delay. Time-sensitive video data is
	automatically sent to this queue.
	Data 2 (best effort)
	Medium priority queue, medium throughput and delay. Most traditional IP data
	is sent to this queue.
	Data 3 (Background)
	Lowest priority queue, high throughput. Bulk data that requires maximum
	throughput and is not time-sensitive is sent to this queue (FTP data, for exam-
	ple).
	For more information, see “QoS Queues and Parameters to Coordinate Traffic
	Flow” on page 144.
AIFS	The Arbitration Inter-Frame Spacing (AIFS) specifies a wait time (in millisec-
(Inter-Frame Space)	onds) for data frames.
	For more information, see “EDCF Control of Data Frames and Arbitration Inter-
	frame Spaces” on page 145.
