“Combined with Bluetooth Low Energy, we’re already down to a couple of inches.
And there are several ways a trio of drones could do the
same thing for all cell/radio devices in an area.”
GPS is for outdoor, BLE is for indoor. How can you combine them?
Drones. Sensors. Phone to phone, or back doors, or opt-ins.
BLE is short distance, but nothing stops it from working outside as well.
So a Drone with its own GPS along with BLE, or just the
passive ability to detect BLE (or whatever type of signals
you care to design for) can fly around and take multiple
measurements, and share with other units doing the same and
thus triangulate in 3 space all the target emissions.
Or Back doors into device operating systems or apps could
allow the target devices to do all the work for you.
Or people can opt into apps on their devices that will do it all.
Or those apps can be required, like in China, and report
your current immunity status as well.
I have one of those fancy FLIR cameras you can plug into
your phone and see someone’s face temperature from 10 feet
away.
Those can be used on drones, or kiosks, or anywhere, too.
The tech is easy. Stopping our would be masters from
controlling us with it is another matter.
