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.
