Configuring the Wireless Array 323
RF Power & Sensitivity
For an overview of RF power and cell size settings, please see “Cap
acity and Cell
Sizes” on page 32 and “Fine Tuning Cell Sizes” on page 33.
5. Set Cell Size: Cell Size may be set globally for all enabled IAPs to Auto,
Large, Medium, Small, or Max using the buttons.
6. Auto Cell Period (seconds): You may set up auto-configuration to run
periodically, readjusting optimal cell sizes for the current conditions.
Enter a number of seconds to specify how often auto-configuration will
run. If you select None, then auto-configuration of cell sizing will not be
run periodically. You do not need to run Auto Cell often unless there are a
lot of changes in the environment. If the RF environment is changing
often, running Auto Cell every twenty-four hours (86400 seconds) should
be sufficient). The default value is None.
7. Auto Cell Size Overlap (%): Enter the percentage of cell overlap that will
be allowed when the Array is determining automatic cell sizes. For 100%
overlap, the power is adjusted such that neighboring Arrays that hear
each other best will hear each other at -70dB. For 0% overlap, that number
is -90dB. The default value is 50%.
8. Auto Cell Min Cell Size: Use this setting if you wish to set the minimum
cell size that Auto Cell may assign. The values are Default, Large,
Medium, or Small.
9. Auto Cell Min Tx Power (dBm): Enter the minimum transmit power that
the Array can assign to a radio when adjusting automatic cell sizes. The
default value is 10.

To use the Auto Cell Size feature, the following additional settings are
required:
RF Monitor Mode must be turned On. See “RF Monitor” on page 321.
One of the radios must be in monitor mode, and all other IAPs that will use
Auto Cell must have Cell Size set to auto. See “Procedure for Manually
Configuring IAPs” on page 280.
