‘You’re going to detect it from mere feet away’
Sorry, thats incorrect. I’ve literally seen not just demonstrations of the capabilities in this area, I personally witnessed some of the stuff done during the Walker spy case from inside the facility’s he ‘attacked’ via his son and a techie back then. And that took place in 1980 or so.
We agree to disagree, no big deal.
In any event, how do you plan to characterize Zero's RF phone emissions to the point where you can discriminate between his emissions and the other thousands of devices emissions in the area?
