AIFSN (Arbitration Inter-Frame Space) — The minimum amount of wait time
before the next data transmission attempt. Specify the AIFS value in the range 0-15
microseconds.
◆
CWMin (Minimum Contention Window) — The initial upper limit of the random
backoff wait time before wireless medium access can be attempted. The initial wait
time is a random value between zero and the CWMin value. Specify the CWMin value
in the range 0-15 microseconds. Note that the CWMin value must be equal or less
than the CWMax value.
◆
CWMax (Maximum Contention Window) — The maximum upper limit of the
random backoff wait time before wireless medium access can be attempted. The
contention window is doubled after each detected collision up to the CWMax value.
Specify the CWMax value in the range 0-15 microseconds. Note that the CWMax
value must be greater or equal to the CWMin value.
◆
Txop (Transmit Opportunity Limit) — The maximum time an AC transmit queue
has access to the wireless medium. When an AC queue is granted a transmit
