Configuring the Wi-Fi Array 279
RF Power & Sensitivity
For an overview of RF power and cell size settings, please see “Capacity and Cell
Sizes” on page 52 and “Fine Tuning Cell Sizes” on page 53.
8. Cell Size Configuration: Click on the Auto Configure button to instruct
the Array to determine and set the best cell size for each enabled IAP,
based on changes in the environment. This is the recommended method
for setting cell size. On the IAP settings window, each enabled IAP will
have its cell size set to Auto.
9. Auto Cell Size Period: 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).
10. 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.
11. Auto Cell Min Tx Power (dBm): Enter the minimum transmit power that
the Array can assign to a radio when adjusting automatic cell sizes.

To use the Auto Cell feature, the following additional settings are required:
The abg(n)2 radio 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 256.
The Intrusion Detection Mode must not be set to Advanced. See “RF
Intrusion Detection” on page 277.
