applied to the multimedia application or a voice call. The adapter will fast roaming to the near 
network when the receive sensitivity (signal strength) is lower to the value you have set up. 
Turn  Off  RF  Button:  If  you  want  to  turn  off  the  radio  of  the  adapter  temporarily,  click  this 
button. To turn on the radio, click this button again. 
Radio On: Indicate to turn on radio.

CCX 2.0: CCX 2.0 (Cisco Compatible  Extensions) is  developed  by Cisco for the  radio 
monitoring and fast roaming. 
LEAP Turn on CCKM: During  normal  operation,  LEAP-enabled  client  devices  mutually 
authenticate with a new access point by performing a complete LEAP authentication, including 
communication with the main RADIUS server. 
  When you configure your wireless LAN for fast re-association, however, LEAP-enabled 
client devices roam from one access point to another without involving the main server. Using 
Cisco Centralized Key Management (CCKM), and access point configured to provide Wireless 
Domain Services (WDS) takes the place of the RADIUS server and authenticates the client so 
quickly that there is no perceptible delay in voice or other time-sensitive applications. 
Enable Radio Measurement: When this parameter is enabled, the Cisco AP can run the radio 
monitoring through the associated CCX-compliant clients to continuously monitor the WLAN 
radio environment and discover and new APs that are transmitting beacons. 
Non-Serving Channel Measurements: The Cisco AP can perform monitoring measurements 
through the CCX-compliant clients on  the  non-serving  channels  when  this  parameter  is 
enabled. 
Limit xxx milliseconds (0-2000): It limits the channel measurement time. The default value is 
250 milliseconds.
