Configuring Cell Size Reduction using the CLI
The Cell Size Reduction feature allows you to manage dense deployments and to increase overall system
performance and capacity by shrinking a W-IAPs receive coverage area, thereby minimizing co-channel
interference and optimizing channel reuse.
The default 0 dB reduction allows the radio to retain its current default Rx sensitivity value.
Values from 1 dB–55 dB reduce the power level that the radio can hear by that amount. If you configure this
feature to use a non-default value, you must also reduce the radio’s transmission (Tx) power to match its new
received (Rx) power level. Failure to match a device’s Tx power level to its Rx power level can result in a
configuration that allows the radio to send messages to a device that it cannot hear.
To configure Cell Size Reduction for 2.4 GHz radio profile in the CLI:
(Instant AP)(config)# rf dot11g-radio-profile
(Instant AP)(RF dot11g Radio Profile)# cell-size-reduction <reduction>
(Instant AP)(RF dot11g Radio Profile)# end
(Instant AP)# commit apply
To configure Cell Size Reduction for 5 GHz radio profile in the CLI:
(Instant AP)(config)# rf dot11a-radio-profile
(Instant AP)(RF dot11a Radio Profile)# cell-size-reduction <reduction>
(Instant AP)(RF dot11a Radio Profile)# end

ARM Channel Selection using the CLI
Starting from Instant 6.5.0.0-4.3.0.0, W-IAPs can search for a new environment in a short span of time, so that
the ARM is triggered to perform frequent scanning and selection of a valid channel for transmission.
