This tool is able to select out header fields/flags from either live or recorded 802.11 traffic. Tcpdump and Tethereal have limited flexibility to tease out specific fields without printing out the entire packet.

| output | An example use of this tool is to process large capture files and
then perform mathematical analysis on the values contained in the fields.
Here is an example output of the tool in use:
%./wifi_parser -p -r mapreceiver-mapsampler1-100000.cap
-s aibstq -c 100
