Why don’t you add GPS module for having a real wardriving device?
It would be able to save GPS coordinates whenever a handshake is captured and plot it on a map (like pwnagotchi project).
Some RPZW module includes global 3G/2G cellular modem with GPS + SIM.
It’s quite expensive but it adds GPS capability in addition to an extra remote GSM C2 capabilitiy…
And it’s completely adapted to RPIZW
