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 (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 (Instant AP)(RF dot11a Radio Profile)# end (Instant AP)# commit apply 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.
