But also, don't builders have to submit plans of homes to the local government when building them for approval?
Your government probably knows your floor plan (though, I don't think they tend to be publicly accessible). Either way though, neither of these methods are anywhere near enough to do what was shown off in those Wi-Fi tracking demos. Here's hoping the tech doesn't get a lot better or has a series of unexpected breakthroughs.
You’re not going from a floor plan to a precise location model. Just think about how different the WiFi environment would be if someone put their router next to their steel computer case versus someone setting it on a nice MDF cabinet with no wires nearby. Completely different RF environment and pathing.
