Max . Burst The Max Burst Length is an AP EDCA parameter and
only applies to traffic flowing from the AP to the client
Length
station
This value specifies (in milliseconds) the maximum
burst length allowed 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
Valid values for maximum burst length are 0 0
through 999
Wi-Fi Multimedia Settings
Wi-Fi Multimedia
Wi-Fi Multimedia (WMM) is enabled by default With
WMM enabled, QoS prioritization and coordination
of wireless medium access is on With WMM enabled,
QoS settings on the access point control downstream
traffic flowing from the AP to client station (AP EDCA
parameters) and the upstream traffic flowing from
the station to the AP (station EDCA parameters)
Disabling WMM deactivates QoS control of station
EDCA parameters on upstream traffic flowing from
the station to the AP
With WMM disabled, you can still set some parameters
on the downstream traffic flowing from the AP to the
client station (AP EDCA parameters)
To disable WMM extensions, click Disabled
To enable WMM extensions, click Enabled
Section 3: Configuring the Access Point
Station EDCA Parameters
Queue Queues are defined for different types of data
transmitted from station-to-AP:
• Data 0 (Voice) — Highest priority queue, minimum
delay Time-sensitive data such as VoIP and
streaming media are automatically sent to this
queue
• Data 1(Video) — Highest priority queue, minimum
delay Time-sensitive video data is automatically
sent to this queue
• Data 2 (best effort) — Medium priority queue,
medium throughput and delay Most traditional IP
data is sent to this queue
• Data 3 (Background) — Lowest priority queue, high
throughput Bulk data that requires maximum
throughput and is not time-sensitive is sent to this
queue (FTP data, for example)
Arbitration Inter-Frame Spacing (AIFS) specifies a wait
AIFS
time for data frames The wait time is measured in
(Inter-Frame
slots Valid values for AIFS are 1 through 255
Space)
cwMin This parameter is used by the algorithm that
determines the initial random backoff wait time
(Minimum
(window) for retry of a data transmission during
Contention

Window)
resources The value specified here in the Minimum
Contention Window is the upper limit (in milliseconds)
of a range from which the initial random backoff wait
time will be determined The first random number
generated will be a number between 0 and the
number specified here If the first random backoff
wait time expires before the data frame is sent, a retry
counter is incremented and the random backoff value
(window) is doubled Doubling will continue until the
size of the random backoff value reaches the number
defined in the Maximum Contention Window
