Parameter Description
Tx Rate There are several options including
Auto/1/2/5.5/11/6/9/12/18/24/36/48/54Mbps for you to select.
When the “Auto” is selected, the device will choose the most
suitable transmission rate automatically. The higher data rate you
designated in the network, the shorter distance is allowed between
the adapter and the wireless stations.
When the wireless mode is “802.11 B only”, the maximum data rate
is 11Mbps (11b) so that there are only “Auto/1/2/5.5/11Mbps”
options you can select.
Tx BURST Tx Burst enables the adapter to deliver better throughput in the
same period and environment.
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 adapter 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 adapter is
applied to the multimedia application or a voice call, you can
enable the parameter. 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.
CCX 2.0 CCX 2.0 (Cisco Compatible Extensions) is developed by Cisco for
the radio monitoring and fast roaming.
