19.2.2 Enabling/Disabling Wi-Fi Multimedia

By default, Wi-Fi MultiMedia (WMM) is enabled on the access point. With WMM enabled,

QoS prioritization and coordination of wireless medium access is on. With WMM enabled,

QoS settings on the 9160 G2 Wireless Gateway control downstream traffic flowing from the

access point to client station (AP EDCA parameters) and the upstream traffic flowing from

the station to the access point (station EDCA parameters).

Disabling WMM will deactivate QoS control of station EDCA parameters on upstream

traffic flowing from the station to the access point With WMM disabled, you can still set pa-

rameters on the downstream traffic flowing from the access point to the client station (AP

EDCA parameters).

• To disable WMM extensions, click Disabled.

• To enable WMM extensions, click Enabled.

19.2.3 Configuring Station EDCA Parameters

Station Enhanced Distributed Channel Access (EDCA) Parameters affect traffic flowing

from the client station to the access point.

Max. Burst Length

AP EDCA Parameter Only

(The Max. Burst Length applies only to traffic flowing from the access point

to the client station.)

This value specifies (in milliseconds) the Maximum Burst Length allowed for packet bursts on the wire-

less 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

999.9

For more information, see “Packet Bursting For Better Performance” on page 191.
