... "Wifi" is radio waves. Tech used in detecting and reading radio waves inside structures has been around for generations, not the few years this sensationalized BS implies. "Absorbing wifi" is misleading in its imprecision as it is the distortion (and movement of such) that reveals said building's contents.

To be clear, US fire departments have been using similar to locate survivors/firefighters lost in obscuring smoke and behind/under structural obstacles for years now.

This is nowhere near new tech. The lack of comprehension by the gen pop makes this seem novel, but it's old news and shouldn't be used to frighten the masses further into psychosis, thanks.
