Minimum Contention Window (milliseconds): This value is
input to the initial random backoff wait time algorithm for
retry of a data frame transmission. The backoff wait time will
be generated between 0 and this value. If the frame is not
sent, the random backoff value is doubled until the value
reaches the number defined by CWMax (below). The CWMin
value must be lower than the CWMax value. The contention
window scheme helps to avoid frame collisions and
determine priority of frame transmission. A shorter window
has a higher probability (priority) of transmission.
Maximum Contention Window (milliseconds): This value is
the upper limit to random backoff value doubling (see
above).
Arbitration Inter-Frame Space (milliseconds): Specifies
additional time between when a channel goes idle and the
AP/client sends data frames. Traffic with a lower AIFSN value
has a higher priority.
Transmission Opportunity (milliseconds): The maximum
interval of time an AP/client can transmit. This makes channel
access more efficiently prioritized. A value of 0 means only
one frame per transmission. A greater value effects higher
priority.
