Installing the Wi-Fi Array 55
Automatic Channel Selection
We recommend that you allow the Array to make intelligent channel allocation
decisions automatically. In the automatic mode, channels are allocated
dynamically, driven by changes in the environment. Auto Channel assignment is
performed by scanning the surrounding area for RF activity on all channels, then
automatically selecting and setting channels on the Array to the best channels
available. This function is typically executed when initially installing Arrays in a
new location and may optionally be configured to execute periodically to account
for changes in the RF environment over time. Auto Channel selection has
significant advantages, including:
z
Allows the Array to come up for the first time and not interfere with
existing equipment that may be already running, thereby limiting co-
channel interference.
z
More accurately tunes the RF characteristics of a Wi-Fi installation than
manual configuration since the radios themselves are scanning the
environment from their physical location.
z
May be configured to run periodically.
To set up the automatic channel selection feature, go to “Advanced RF Settings”
on page 275 . For more information about this feature, see the Xirrus Auto Channel
Application Note in the Xirrus Library .
Manual Channel Selection
You can manually assign channels on a per radio basis, though manual selection
is not recommended (and not necessary).
#
To avoid co-channel interference, do not select adjacent channels for radios
that are physically next to each other.
