Figure 37: WMM Configuration

The following items are displayed in the WMM Configuration window:
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 opportunity, it can transmit data for a time up to
the TxOpLimit. This data bursting greatly improves the efficiency for
high data-rate traffic. Specify a value in the range 0-65535
microseconds.
