动态带宽切换

ARMAdaptive Radio Management. ARM dynamically monitors and adjusts the network to ensure that all users are allowed ready access. It enables full utilization of the available spectrum to support maximum number of users by intelligently choosing the best RF channel and transmit power for APs in their current RF environment.’s dynamic bandwidth switch feature provides capability forARMAdaptive Radio Management. ARM dynamically monitors and adjusts the network to ensure that all users are allowed ready access. It enables full utilization of the available spectrum to support maximum number of users by intelligently choosing the best RF channel and transmit power for APs in their current RF environment.to detect the 20 Mhz interferer by reading theCCAClear Channel Assessment. In wireless networks, the CCA method detects if a channel is occupied or clear, and determines if the channel is available for data transmission.statistics and other radio statistics.

Enabling Dynamic Bandwidth Switch

The followingCLICommand-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions.commands enable and set dynamic bandwidth switch:

(host) [mynode] (config) #rf arm-profile default

(host) [mynode] (Adaptive Radio Management (ARM) profile "default") #dynamic-bw

(host) [mynode] (Adaptive Radio Management (ARM) profile "default") #dynamic-bw-beacon-failed-thresh

(host) [mynode] (Adaptive Radio Management (ARM) profile "default") #dynamic-bw-cca-ibss-thresh

(host) [mynode] (Adaptive Radio Management (ARM) profile "default") #dynamic-bw-cca-intf-thresh
