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.

No Acknowledgement provides control of the reliability of traffic flow. Usually an acknowledge packet is returned for every packet received, increasing traffic load and decreasing performance.

Enabling No Acknowledgement cancels the acknowledgement. This is useful for data traffic where speed of transmission is important.

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

Parameters for Data0 Best Effort.

Best Effort data traffic has no prioritization and applications equally share available bandwidth.

Parameters for Data1 Background.

Background data traffic is de-prioritized and is mostly for backup applications, or background transfers like backup applications or background transfers like bulk copies that do not impact ongoing traffic like Internet downloads.

Parameters for video data traffic.

Parameters for voice data traffic.
