Configuring the Wireless Array 287
Beacon Configuration
6. Beacon Interval: When the Array sends a beacon, it includes with it a
beacon interval, which specifies the period of time before it will send the
beacon again. Enter the desired value in the Beacon Interval field,
between 20 and 1000 Kusecs. A Kusec is 1000 microseconds =
1 millisecond. The value you enter here is applied to all IAPs.
7. DTIM Period: A DTIM (Delivery Traffic Indication Message) is a signal
sent as part of a beacon by the Array to a client device in sleep mode,
alerting the device to broadcast traffic awaiting delivery. The DTIM
Period is a multiple of the Beacon Interval, and it determines how often
DTIMs are sent out. By default, the DTIM period is 1, which means that it
is the same as the beacon interval. Enter the desired multiple, between 1
and 255. The value you enter here is applied to all IAPs.
8. 802.11h Beacon Support: This option enables beacons on all of the
Array’s radios to conform to 802.11h requirements, supporting dynamic
frequency selection (DFS) and transmit power control (TPC) to satisfy
regulatory requirements for operation in Europe.
9. 802.11k Beacon Support: 802.11k offers faster and more efficient roaming.
When enabled, each beacon lists the channels that nearby APs offer. This
supports improved channel scanning, resulting in faster roam times and
increased battery life due to shorter scan times since the station knows
where to look for nearby APs. The Array will also respond to requests
from stations for an 802.11K Neighbor Report with additional
information about nearby APs. This setting is disabled by default.
10. 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.
11. 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
