That’s an odd simile to choose!
It’s troubling how well this works, but it’s an idea people have talked about for a while. The reason the unregulated wifi spectrum exists in the first place is that it’s not as useful as, say, the FM band. And that’s because microwaves in this range are easily scattered by the water and hydrocarbons in things like trees, building materials and people. Which also means microwaves are good for sensing flesh. For a long time there have been motion sensors on the market that use ISM-band microwaves to be able to work through walls and doors.

Radar is a common method looking thru walls to spy on people but pales in comparison with the WiFi resolution.

The Xaver 1000 allows living and static objects to be detected and ‘seen’ behind walls and obstacles.
Uh-huh.

Waiting for cops to use this to spy on people without warrants, arguing that now the whole house counts as “plain view.”

Looks like it’s time to go back to lead paint! LOTS of it.

Maybe with a layer of tinfoil over it?

So I’m not the only one who saw this and immediately thought of Lucius Fox’s reaction to Batman’s similar technology in The Dark Knight, right?

No, that’s better left to Santa Claus.

LOL, I’d love to know how that account is somehow worse than TFG.

There’s a lot of woo in the EMF shielding market, but there are science-based paintable coatings that can effectively attenuate or block low power signals like wifi.
Of course, if you paint your house with one you’ll also need some extra network hardware if you want cellular service inside the house and wifi on your porch.

So, any bets on how long before ISP-provided router/AP widgets start phoning ‘customer telemetry’ home to the mothership?
