cwMin The minimum contention window value is a number that determines
the initial random number range (0 to cwMin). For example, if it can
not be transmitted in the first 0 to 15, random numbers are
generated in the range of 0 to 31 the second time. If it can not be
sent at the second time, the third time range is from 0 to 63. Every
time it can not be transmitted, it will double it to cwMax. If it can not
be sent even if it reaches cwMax, it repeats from 0 to cwMax. It is
reset to cwMin if the frame is sent correctly or the frame is discarded.
This value must be less than or equal to the maximum contention
window value.
You can select 1, 3, 7, 15, 31, 63, 127, 255, 511, 1023. This is one
less than the power of 2.
The defaults are 3 (Data 0), 7 (Data 1), 15 (Data 2), 15 (Data 3).
cwMax Select the maximum contention window value. It must be greater
than or equal to the minimum contention window value.
You can select 1, 3, 7, 15, 31, 63, 127, 255, 511, 1023.
The defaults are 7 (Data 0), 15 (Data 1), 1023 (Data 2),
1023 (Data 3).
TXOP Limit Sets the time that wireless clients can occupy transmission to this
