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.
NoAck (No
Acknowledge
ment)
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.
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.
BE (Best Effort)
Parameters for Data0 Best Effort.
Best Effort data traffic has no prioritization and applications equally
share available bandwidth.
BK
(Background)
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.
VI (Video)
Parameters for video data traffic.
VO (Voice) Parameters for voice data traffic.
