With dBmonster you are able to scan for nearby WiFi devices and track them trough the signal strength (dBm) of their sent packets (sniffed with TShark). These dBm values will be plotted to a graph with matplotlib. It can help you to identify the exact location of nearby WiFi devices (use a directional WiFi antenna for the best results) or to find out how your self made antenna works the best (antenna radiation patterns).

Normally, you can only enable monitor-mode on the internal wifi card from MacOS with the airport utility from Apple. Somehow, wireshark (or here TShark) can enable it too on MacOS. Cool, but because of the MacOS system and Wiresharkβs workaround, there are many issues running dBmonster on MacOS. After some time, it could freeze and/or you have to stop dBmonster/Tshark manually from the CLI with the ps
command. If you want to run it anyway, here are some helpful tips:
Look if there are any processes, named dBmonster, tshark or python:
sudo ps -U root
Now kill them with the following command:
sudo kill <PID OF PROCESS>
sudo airport <WiFi INTERFACE NAME> sniff
Press control + c after a few seconds
