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.
