Description
Possible options are: Custom, Default, Optimized for Voice.
Queues are defined for different types of data transmitted from AP‐to‐station:
• Data 0 (Voice) — H igh priority queue, minimum delay. Time‐sensitive data such
as VoIP and streaming media are automatically sent to this queue.
• Data 1(Video) — H igh priority queue, minimum delay. Time‐sensitive video data
is automatically sent to this queue.
• Data 2 (best effort) — M edium priority queue, medium throughput and delay.
Most traditional IP data is sent to this queue.
• Data 3 (Background) — L owest priority queue, high throughput. Bulk data that
requires maximum throughput and is not time‐sensitive is sent to this queue
(FTP data, for example).
The Arbitration Inter‐Frame Spacing (AIFS) specifies a wait time for data frames.
The wait time is measured in slots. Valid values for AIFS are 1 through 255.
