Wireless Array
298 Configuring the Wireless Array
11. WMM Power Save: Click On to enable Wireless Multimedia Power Save
support, as defined in IEEE802.11e. This option saves power and
increases battery life by allowing the client device to doze between
packets to save power, while the Array buffers downlink frames. The
default setting is On.
12. WMM ACM Video: Click On to enable Wireless Multimedia Admission
Control for video traffic. When admission control for video is enabled, the
Array evaluates a video request from a client device against the network
load and channel conditions. If the network is not congested, it accepts
the request and grants the client the medium time for its traffic stream.
Otherwise, it rejects the request. This enables the Array to maintain QoS
when the WLAN becomes congested after a connection has already been
established. Some clients contain sufficient intelligence to decide to either
delay the traffic stream, associate with a different AP, or establish a best-
effort traffic stream outside the operation of WMM-Admission Control.
The default setting is Off. Note that the QoS priority of traffic queues is
voice, video, best effort, background—this gives the highest priority to
voice transmissions.
13. WMM ACM Voice: Click On to enable Wireless Multimedia Admission
Control for voice calls. As for WMM ACM Video above, when admission
control for voice is enabled, the Array evaluates a voice request from a
client device against the network load and channel conditions. If the
network is not congested, it accepts the request and grants the client the
medium time for its call. Otherwise, it rejects the request. Some clients
contain sufficient intelligence to decide to either delay the traffic stream,
associate with a different AP, or establish a best-effort traffic stream
outside the operation of WMM-Admission Control. The default setting is
Off.
Station Management
14. Station Re-Authentication Period: This specifies an interval (in seconds)
for station reauthentications. This is the minimum time period between
station authentication attempts, enforced by the Array. This feature is
part of the Xirrus Advanced RF Security Manager (RSM).
