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)
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.
Cwmin (Contention
Window Minimum)
Contention Window Minimum is the minimum random wait time drawn from
this interval or window for the backoff mechanism on the network.
CwMax (Contention
Window Maximum)
Contention Window Maximum is the maximum random wait time drawn from
this interval or window for the backoff mechanism on the network.
TxOp limit (Transmit
Opportunity Limit)
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.
ACM (Admission Control
Mandatory)
Admission Control Mandatory enables WMM on the radio interface. When
ACM is enabled, associated clients must complete the WMM admission
control procedure before access.
