Figure 38: 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.
