WMM Parameters (for advanced users)
AIFs (Arbitrary Inter-
Frame Space)
Arbitrary Inter-Frame Space is the fixed wait time for different
data traffic to access the network.
Cwmin (Contention
Window Minimum)
Contention Window Minimum is the minimum random wait time
for different data traffic to access the network.
CwMax (Contention
Window Maximum)
Contention Window Maximum is the maximum random wait time
for different data traffic to access the network.
TxOp limit (Transmit
Opportunity Limit)
Transmit Opportunity limit specifies the duration that an end-user
device can transmit data traffic. TxOp limit can be used to give
data traffic longer and shorter access.
NoAck (No
Acknowledgement)
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.
