Queue displays the transmission queue: Data 0>Data 1>Data 2>Data 3.  Data 0 (Voice)-High priority queue, minimum delay. Time-sensitive data such as VoIP and streaming media are automatically sent to this queue.  Data 1 (Video)-High 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 example). Arbitration Inter-Frame Space: A wait time for data frames. The wait time is measured in slots. Valid values for AIFS are from 0 to 15. Minimum Contention Window: A list to the algorithm that determines the initial random backoff wait time (window) for retry of a transmission. This value must be lower than or equal to the value for the Maximum Contention Window. Maximum Contention Window: The upper limit (in milliseconds) for the doubling of the random backoff value. This doubling continues until either the data frame is sent or the Maximum Contention Window size is reached. Maximum Burst: An EAP EDCA parameter that applies only to traffic flowing from the EAP to the client station. This value specifies (in milliseconds) the maximum burst length allowed for packet bursts on the wireless network. A packet burst is a collection of multiple frames transmitted without header information. The decreased overhead results in higher throughput and better performance. The valid values are multiples of 32 between 0 and 8192. Station EDCA Parameters Station EDCA parameters affect traffic flowing from the client station to the EAP device. TXOP Limit: The TXOP Limit is a station EDCA parameter and only applies to traffic flowing from the client station to the EAP device. The Transmission Opportunity (TXOP) is an interval of time, in milliseconds, when a WME client station has the right to initiate transmissions onto the wireless medium (WM) towards the EAP device. The valid values are multiples of 32 between 0 and 8192. 43

Queue
displays the transmission queue: Data 0>Data 1>Data 2>Data 3.
Data 0 (Voice)—High priority queue, minimum delay. Time-sensitive data such as VoIP and
streaming media are automatically sent to this queue.
Data 1 (Video)—High 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 example).
Arbitration Inter-Frame Space
: A wait time for data frames. The wait time is measured in slots. Valid
values for AIFS are from 0 to 15.
Minimum Contention Window
: A list to the algorithm that determines the initial random backoff wait
time (window) for retry of a transmission. This value must be lower than or equal to the value for the
Maximum Contention Window.
Maximum Contention Window
: The upper limit (in milliseconds) for the doubling of the random
backoff value. This doubling continues until either the data frame is sent or the Maximum Contention
Window size is reached.
Maximum Burst
: An EAP EDCA parameter that applies only to traffic flowing from the EAP to the client
station. This value specifies (in milliseconds) the maximum burst length allowed for packet bursts on the
wireless network. A packet burst is a collection of multiple frames transmitted without header
information. The decreased overhead results in higher throughput and better performance. The valid
values are multiples of 32 between 0 and 8192.
Station EDCA Parameters
Station EDCA parameters affect traffic flowing from the client station to the EAP device.
TXOP Limit
: The TXOP Limit is a station EDCA parameter and only applies to traffic flowing from the
client station to the EAP device. The Transmission Opportunity (TXOP) is an interval of time, in
milliseconds, when a WME client station has the right to initiate transmissions onto the wireless medium
(WM) towards the EAP device. The valid values are multiples of 32 between 0 and 8192.
