cwMax
Enter the maximum contention window (cwMax) value that specifies the upper limit (in
milliseconds) for the doubling of the random back-off value. Decreasing this value
increases the priority of the queue. The value for cwMax needs to be higher than the value
for cwMin. Valid values are 0, 1, 3, 7, 15, 31, 63, 127, 255, 511, and 1023.
The default values are Data 0: 63; Data 1: 1023; Data 2: 15; Data 3: 7.
Max. Burst
Enter the maximum burst value that specifies the maximum burst length (in microseconds)
allowed for packet bursts on the wireless network. A packet burst is a collection of multiple
frames transmitted without header information. Decreasing this value increases the priority
of the queue. Valid values for maximum burst length are all multiples of 32 between 0 and
8192, inclusive of 0 and 8192.
The default values are Data 0: 0; Data 1: 0; Data 2: 3008; Data 3: 1504.
Station EDCA parameters
AIFS
Enter the Arbitration Inter-Frame Spacing (AIFS) interval that specifies the wait time (in
milliseconds) between data frames. A higher AIFS value means a higher priority for a
queue. Valid values for AIFS are 0 through 8.
The default values are Data 0: 3; Data 1: 7; Data 2: 2; Data 3: 2.
cwMin
Enter the minimum contention window (cwMin) value that specifies the upper limit (in
milliseconds) of a range from which the initial random back-off wait time is determined.
Decreasing this value increases the priority of the queue. The value for cwMin needs to be
lower than the value for cwMax. Valid values are 0, 1, 3, 7, 15, 31, 63, 127, 255, 511, and
1023.
The default values are Data 0: 15; Data 1: 15; Data 2: 7; Data 3: 3.
cwMax
Enter the maximum contention window (cwMax) value that specifies the upper limit (in
milliseconds) for the doubling of the random back-off value. Decreasing this value
increases the priority of the queue. The value for cwMax needs to be higher than the value
for cwMin. Valid values are 0, 1, 3, 7, 15, 31, 63, 127, 255, 511, and 1023.
The default values are Data 0: 1023; Data 1: 1023; Data 2: 15; Data 3: 7.
TXOP Limit
Enter the transmission opportunity (TXOP) value that specifies the time interval (in
microseconds) in which a client station can initiate transmissions on the wireless medium
(WM). Decreasing this value increases the priority of the queue. Valid values for TXOP
Limit are all multiples of 32 between 0 and 8192, inclusive of 0 and 8192.
The default values are Data 0: 0; Data 1: 0; Data 2: 3008; Data 3: 1504.
