Transmit Threshold Control 

Fragmentation 

Threshold 

The threshold (number of bytes) for the fragmentation boundary for directed 
messages. It is the maximum data fragment size that can be sent.  
Move the slider to set the fragmentation threshold.  

RTS/CTS Threshold  Data with its frame size larger than this value will perform the RTS/CTS handshake. 

Setting this attribute to be larger than the maximum MSDU (MAC service data unit) 
size turns off the RTS/CTS handshake. Setting this attribute to zero turns on the 
RTS/CTS handshake.  
Move the slider to set the RTS/CTS threshold.
