280 Configuring the Wi-Fi Array
12. Sharp Cell: This feature reduces interference between neighboring
Arrays or other Access Points by limiting to a defined boundary (cell size)
the trailing edge bleed of RF energy. Choose On to enable the Sharp Cell
functionality, or choose Off to disable this feature. See also, “Fine Tuning
Cell Sizes” on page 53.
The Sharp Cell feature only works when the cell size is Small, Medium, or
Large (or Auto)—but not Max. If an IAP cell size is set to Max, the Sharp
Cell feature will be disabled for that radio.

13. Channel Configuration: Automatic channel configuration is the
recommended method for channel allocation. When the Array performs
auto channel configuration, it first negotiates with any other nearby
Arrays that have been detected, to determine whether to stagger the start
time for the procedure slightly. Thus, nearby Arrays will not run auto
channel at the same time. This prevents Arrays from interfering with each
other’s channel assignments.
Click Auto Negotiate & Configure to instruct the Array to determine the
best channel allocation settings for each IAP and select the channel
automatically, based on changes in the environment. The Array will first
negotiate with other nearby Arrays to see if the start time needs to be
staggered slightly.
Click Auto Configure to perform auto channel configuration
immediately, without first negotiating with any nearby Arrays. This
option is faster than Auto Negotiate and Configure. This allows you to
manually perform auto channel without waiting, and may be used when
you know that no other nearby Arrays are configuring their channels. If
multiple Arrays are configuring channels at the same time, use the Auto
Negotiate option to be ensure that multiple Arrays don't select the same
channels.
Click Factory Defaults to instruct the Array to return all IAPs to their
factory preset channels, as shown in the table below.
