Preamble helps to synchronize sender and receivers clocks and also help to identify 
the start of data. Setting the preamble type to long help to synchronize the clocks 
more accurately, but it takes up bandwidth. Setting preamble to automatic is 
highly recommended. 
Fragmentation threshold specify the maximum data size before the data is been 
fragmented. Refer to the tutorial
 section on why we need to fragment data 
packets. 
Request To Send (RTS) and Clear To Send (CTS) specify the maximum data size 
before a RTS management packet is send out to the network requesting for 
temporal usage of the network. That is, the host will get temporal maximum 
bandwidth available to the network. 
Setting the value to maximum (2346 and 2347 respectively) will disable the setting.
