Tx Power: Transmit power, the amount of power used by
a radio transceiver to send the signal out. Select the Tx
power percentage from the pull-down list including Auto,
100%, 75%, 50%, 25%, 10% and Lowest.
Preamble: This function will show up when Ad-hoc
network type be selected. A preamble is a signal used in
wireless environment to synchronize the transmitting
timing including Synchronization and Start frame
delimiter. Select from the pull-down menu to change the
Preamble type into Auto or Long.
RTS Threshold: User can adjust the RTS threshold
number by sliding the bar or key in the value directly. The
default value is 2347. RTS/CTS Threshold is a mechanism
implemented to prevent the “Hidden Node” problem. If
the “Hidden Node” problem is an issue, users have to
specify the packet size. The RTS/CTS mechanism will be
activated if the data size exceeds the value you set. This
value should remain at its default setting of 2347. Should
you encounter inconsistent data flow, only minor
modifications of this value are recommended.
Fragment Threshold: User can adjust the Fragment
threshold number by sliding the bar or key in the value
directly. The default value is 2346. The mechanism of
Fragmentation Threshold is used to improve the efficiency
when high traffic flows along in the wireless network. If
your Wireless LAN Adapter often transmits large files in
wireless network, you can enter new Fragment Threshold
value to split the packet. The value can be set from 256 to
2346.
