Wi-Fi Array
Configuring the Wi-Fi Array 279
Beacon Configuration
5. 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.
6. 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.
7. 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.
Station Management
8. 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).
9. Station Timeout Period: Specify a time (in seconds) in this field to define
the timeout period for station associations.
10. Max Station Association per Array: This option allows you to define
how many station associations are allowed per Array (up to 1536 stations
per Array). Note that the Max Station Association per IAP limit (below)
may not be exceeded. If you have an unlicensed Array, this value is set to
1, which simply allows you to test the ability to connect to the Array.
11. Max Station Association per IAP: This defines how many station
associations are allowed per IAP (up to 96 stations per IAP). Note that the
