Fragment Threshold Fragmentation is used for improving
efficiency when there is a lot of network
traffic. If your 802.11g Wireless Adapter
often transmits large files into the wireless
network, you can enter a new Fragment
Threshold value to split the packet. The
value can be set from 256 to 2346. The
default value is 2346.
RTS Threshold RTS Threshold is implemented to prevent the
“Hidden Node” problem. A “Hidden Node”
results when two stations are within range of
the same Access Point, but are not within
range of each other. Therefore, they are
hidden from each other. When a station starts
communication 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 Point, informing that it is going to
transmit the data. Upon receipt, the Access
Point will respond with a CTS message to tell
all stations within range to defer transmission.
It will also confirm to the requesting station
that the Access Point has reserved it for the
time-frame of the requested transmission.
If the “Hidden Node” problem is an issue,
please specify the packet size. The RTS
mechanism will be activated if the data size
exceeds the value you set.. The default value
is 2347*.
Warning: Enabling RTS Threshold will
cause some network overhead that could
negatively affect network performance
