Chapter 4 Common Configuration

Depending on the mode you set up, you have to select either AP (Access Point) or BSS ( Basic Service Set) WMM Parameters. For instance, if the mode is AP, select AP WMM Parameters. The following parameters are described :

WMM Parameters (for advanced users)

AIFs (Arbitrary Inter-

Frame Space)

Cwmin (Contention Window Minimum)

CwMax (Contention Window Maximum)

TxOp limit (Transmit

Opportunity Limit)

ACM (Admission Control

Mandatory)

Arbitrary Inter-Frame Space is the minimum wait time interval between the wireless medium becoming idle and the start of transmission of a frame over the network.

Contention Window Minimum is the minimum random wait time drawn from

this interval or window for the backoff mechanism on the network.

Contention Window Maximum is the maximum random wait time drawn from

this interval or window for the backoff mechanism on the network.

Transmit Opportunity limit specifies the minimum duration that an end-user device can transmit data traffic after obtaining a transmit opportunity. TxOp limit can be used to give data traffic longer and shorter access.

Admission Control Mandatory enables WMM on the radio interface. When ACM is enabled, associated clients must complete the WMM admission control procedure before access.
