CwMin Specify an upper limit (in milliseconds) of a range from which the initial random
backoff wait time is determined.
Valid values for this field are 1, 3, 7, 15, 31, 63, 127, 255, 51

, or 1023. The value
for the minimum contention window (CwMin) must be lower than the value for the
maximum contention window (CwMax).
The following are the default values for
the
AP EDCA parameters:
• Data 0 (Best Effort). 15
• Data 1 (Background)
. 15
• Data 2 (V
ideo)
. 7
• Data 3 (Voice)
. 3
The following are the default values for
the Station EDCA parameters:
• Data 0 (Best Effort). 15
• Data 1 (Background). 15
• Data 2 (V
ideo)
. 7
• Data 3 (Voice)
. 3
CwMax Specify an upper limit (in milliseconds) for the doubling of the random backoff value.
Valid values for this field are 1, 3, 7, 15, 31, 63, 127, 255, 51

, or 1023. The value
for the maximum contention window (CwMax) must be higher than the value for
minimum contention window (CwMin).

Max Burst
Note: AP EDCA
parameters only
Specify (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. V
alid values for maximum burst length are
0 through 8192. The
maximum burst length applies only to AP EDCA parameters.
The following are the default values for the AP EDCA parameters:
• Data 0 (Best Effort). 0
• Data 1 (Background). 0
• Data 2 (V
ideo). 3008
• Data 3 (Voice)
. 1504
TXOP Limit
Note: Station EDCA
parameters only
Specify the transmission opportunity (TXOP) limit.
The TXOP limit applies only to station AP EDCA parameters and specifies the
maximum period during which the client station client can initiate transmissions.
The following are the default values for the Station EDCA parameters:
• Data 0 (Best Effort). 0
• Data 1 (Background). 0
• Data 2 (V
ideo)
. 3008
• Data 3 (Voice). 1504
