310 Configuring the Wireless Array
Procedure for Configuring Global 802.11n IAP Settings
1. 802.11n Data Rates: The Array allows you to define which data rates are
supported for all 802.11n radios. Select (or deselect) 11n data rates by
clicking in the corresponding Supported and Basic data rate check boxes.
• Basic Rate — a wireless station (client) must support this rate in
order to associate.
• Supported Rate — data rates that can be used to transmit to
clients.
2. 802.11n Mode: Select Enabled to allow the Array to operate in 802.11n
mode.
If you select Disabled, then 802.11n operation is disabled on the Array.
3. TX Chains: Select the number of separate data streams transmitted by the
antennas of each IAP. The maximum number of chains is determined by
whether the XR Series Array has 2x2 or 3x3 radios. The default value is
always the maximum supported by the radio type. See “Multiple Data
Streams — Spatial Multiplexing” on page 39.
4. RX Chains: Select the number of separate data streams received by the
antennas of each IAP. This number should be greater than or equal to TX
Chains. The maximum number of chains is determined by whether the
XR Series Array has 2x2 or 3x3 radios. The default value is always the
maximum supported by the radio type. See “Multiple Data Streams —
Spatial Multiplexing” on page 39.
5. Guard interval: Select Short to increase the data transmission rate by
decreasing wait intervals in signal transmission. Select Long to use the
standard interval. The default is Short. See “Short Guard Interval” on
page 41.
6. Auto bond 5 GHz channels: Select Enabled to use Channel Bonding on
5 GHz channels and automatically select the best channels for bonding.
The default is Enabled. See “Channel Bonding” on page 40.
