Preamble Type

Preamble is used to signal that data is coming to the receiver. Short preamble 
increases performance as less time sending preamble means more time for 
sending data. All IEEE 802.11b/g compliant wireless adapters support long 
preamble, but not all support short preamble.
The NWD271N automatically uses short preamble when the access point 
supports it; otherwise the NWD271N uses long preamble. 
At the time of writing, this field is not available in Windows Vista.
