RTS 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 Point,
informing that it is going to transmit the data. Upon receipt, the Access Point will respond
with a CTS message to all station within its range to notify all other stations to defer
