Fragmentation mechanism is used for improving the
efficiency when high traffic flows along in the
wireless network. If your 802.11g Wireless LAN PC
Card often transmit 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.
The default value is 2346. Fragment Threshold
RTS Threshold is a mechanism implemented to
prevent the “Hidden Node” problem. “Hidden Node” is
a situation in which two stations are within range of the
same Access Point, but are not within range of each
other. Therefore, they are hidden nodes for each other.
When a station starts data transmission with the
Access Point, it might not notice that the other station
is already using the wireless medium. When these two
stations send data at the same time, they might collide
when arriving simultaneously at the Access Point. The
collision will most certainly result in a loss of messages
for both stations.
Thus, the RTS Threshold mechanism provides a
solution to prevent data collisions. When you enable
RTS Threshold on a suspect “hidden station”, this
station and its Access Point will use a Request to Send
(RTS). The station will send an RTS to the Access
RTS Threshold
