Wi-Fi Array
256 Configuring the Wi-Fi Array
• YELLOW—The channel has less than optimum separation (some
degree of overlap with neighboring radios).
• GRAY—The channel is already in use.
Select Auto to have the Array dynamically select a channel automatically,
based on changes in the Wi-Fi environment. See “Allocating Channels”
on page 54. After you click Apply, this window and the IAPs window
will show the channel that was assigned, rather than Auto.
The channels that are available for assignment to an IAP will differ,
depending on the country of operation. If Country is set to United States
in the Global Settings (IAP) window, then 24 channels are available to
802.11a(n) radios.
If you have enabled Public Safety in the Advanced RF Settings window
(Step 18), then the public safety band channels (191 and 195) in the
4.9GHz spectrum range will be listed. Operating these channels requires
a license—using these channels without a license violates FCC rules.
Warning notices are displayed when you select these channels.
4. The Bonding column only appears for XN Array models. It works
together with the Auto Channel Bonding and Dynamic/Static options
selected on the Global Settings .11n page. Also see the discussion of
802.11n bonding in “Channel Bonding” on page 63.
• Off—This channel is not bonded to another channel.
• On—This channel is bonded to an adjacent channel. The bonded
channel is selected automatically by the Array based on current
conditions. The choice of banded channel may be dynamic, changing
as needed; or it may be static—fixed once the selection is made.
• +1—This channel is bonded to the next higher channel number. Auto
Channel bonding does not apply.

As mandated by FCC law, Arrays continually scan for signatures of military
radar. If such a signature is detected, the Array will switch operation from
conflicting channels to new ones.
