# Parsing 802.11 Beacon Frames
This example shows the reader how to parse 802.11 Beacons from a pcap, outputting the SSID, BSSID, Channel, Security Information, and more to the terminal.

# Building and Using
```
>> cd examples/parse_beacon/
>> make
clang -Wall -Werror -O3 -o parse_beacon   -c -o parse_beacon.o parse_beacon.c
clang -Wall -Werror -O3 -o parse_beacon parse_beacon.c -lpcap -lwifi 
>> ./parse_beacon --file ~/beacon.pcap                                                                                                                                                                                                                      [1/789]
