Parameter arm-profile beacon-period beacon-regulate cap-reg-eirp cell-size-reduction channel Description Configures Adaptive Radio Management (ARM) feature. See rf arm-profile on page 714. Range - Default "default" Time, in milliseconds, between successive beacon transmissions. The beacon advertises the AP's presence, identity, and radio characteristics to wireless clients. 60-2000 (millisecond s) 100 (millisecond s) Enabling this setting introduces - randomness in the beacon generation so that multiple APs on the same channel do not send beacons at the same time, which causes collisions over the air. disabled Work around a known issue on Cisco 7921G telephones by specifying a cap for a radio's maximum equivalent isotropic radiated power (EIRP). When you enable this parameter, even if the regulatory approved maximum for a given channel is higher than this EIRP cap, the AP radio using this profile will advertise only this capped maximum EIRP in its radio beacons. 1-31 dBm. The cell size reduction feature allows you manage dense deployments and to increase overall system performance and capacity by shrinking an AP's receive coverage area, thereby minimizing co-channel interference and optimizing channel reuse. This value should only be changed if the network is experiencing performance issues. The possible range of values for this feature is 0-55 dB. 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 nondefault 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. 1-5 5dB 0 dB Channel number for the AP 802.11a/802.11n.802.11ac physical layer. The available channels depend on the regulatory domain (country).
