Now they can watch you inside your house

BI-

Wi-Fi can pass through walls.

This fact is easy to take for granted, yet it’s the reason we can surf the web using a wireless router located in another room.

But not all of that microwave radiation makes it to (or from) our phones, tablets, and laptops. Routers scatter and bounce their signal off objects, illuminating our homes and offices like invisible light bulbs.

Now, German scientists have found a way to exploit this property to take holograms, or 3D photographs, of objects inside a room — from outside it.

“It can basically scan a room with someone’s Wi-Fi transmission,” Philipp Holl, a 23-year-old undergraduate physics student at the Technical University of Munich, told Business Insider.

  1. Radar of a sort. Very capable, too.
    The next generation, 5, uses frequencies similar to those used for crowd control, by being able to stimulate pain receptors in the skin. What is next?

  2. I live on a dead end road with four houses. I’m
    not worried about this shit.
    Even named my my WIFI network “The H Project”. 😉

  3. Tech is always going to advance, and man will always find ways to use it for good and evil. What’s troubling to me is how few people see the potential down side to this sort of thing. It’s convenient to unlock your house from an app on your phone, while you’re away. But that can get hacked, or abused. No thanks. Best Buy has a whole section of this stuff, called ‘Connected Home’. See, you’re a caveman if you don’t ‘connect’. Again, no thanks.
