cwMax (Maximum
Contention Window)
Specifies the maximum contention
window, which is the upper limit (in
milliseconds) for doubling the random
backoff value. The doubling continues
until either the data frame is sent or the
maximum contention size is reached.
Once the maximum contention window is
reached, retries continue until a maximum
number of retries is reached.
Valid values for this parameter are: 1, 3, 7,
15, 31, 63, 127, 255, 511, and 1023. This
parameter must be higher than the cwMin
value.
Max. Burst Length Specifies the maximum burst length (in
milliseconds) for packet bursts on the
wireless network. A packet burst is a
collection of multiple frames transmitted
without header information. The
decreased overhead results in higher
throughput and better performance.
This is an AP EDCA parameter only and
as such applies only to egress traffic from
the access point to the clients.
The range is 0.0 to 999 milliseconds.
Wi-Fi Multimedia Enables or disables QoS prioritization and
coordination. When WMM is enabled, the
access point uses the AP EDCA settings
to control the flow of downstream traffic to
the wireless clients and the station EDCA
parameters to control the flow of upstream
traffic from the clients.
When WMM is disabled, QoS control of
the upstream traffic from the clients is
disabled. You can still continue to
configure some of the parameters that
control the downstream traffic from the
access point to the clients
