Parameter Description 
Enable TCP Window Size
The TCP Window is the amount of data a sender can send on a 
particular connection before it gets an acknowledgment back from 
the receiver that it has gotten some of it. When the Router or AP 
the card is connecting to have set up the TCP Window, you can 
enable the parameter to meet the data size for the Router or AP 
connection. The larger TCP Window the better performance. 
Fast Roaming at -70dBm
When you want to fast roaming to the network nearby without 
intercepting the wireless connection especially the card is applied 
to the multimedia application or a voice call, you can enable the 
parameter. The card 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 card temporarily, click this 
button. To turn on the radio, click this button again. 
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), an 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 
any 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.
