I've noticed, recently, that literally every major chain store I go into blocks my cell signal. I get full bars outside, perfect LTE, and about 5 ft past the glass doors, I'm suddenly cut off. Specifically, Meijer grocery stores and Home Depot are the worst offenders. Coincidentally they offer free in store WiFi to track me with, so I turn off my wifi radio on both smartphone and smartwatch before walking in the door…

I believe you can achieve the same result in your home by adding a sheet metal roof, metal cabinets, and refrigerators along every wall.

It's a rather unfortunate coincidence, isn't it? Certainly it's not their fault that their buildings just happen to be constructed in such a way, and their products arranged such that it blocks signal causing customers to not be able to compare prices and have to use their approved internet connection. /s

I see this in the Targets in my town. I just expect signal to drop to zero.

My Lowe's and Home Depot both have free Wifi. I use it all the time to use their app or site to find the location of items in store (obv. can't talk to humans).

In a 5-4 decision in https://en.wikipedia.org/wiki/Kyllo_v._United_States , the SCOTUS determined that police can't use thermal imaging on a house without a search warrant. I wonder what the vote would have been if the justices could have seen videos like this.

With this paper our last shreds of privacy are being taken away, but they presented the news with nice background music, so there's that.

Meh, that seems a little sensationalist. Any significant metal would likely throw this in a loop. You could even buy paint with graphite in it to block weak RF signals outright. IIRC most military bases and data centers protect against this sort of leakage.

Maybe even chicken wire in the walls.

Love it. This is a game mechanic / movie superhero device that's been around a long time, just love the fact that this does it so simply and with so much promise. As sensitivity and the quality of the neural net increases, combined with AR, this is going to make super soldiers out of SWAT teams.

Maybe SWAT can use this to validate that it's actually the right house when serving a no-knock warrant. I'm cynical enough to feel like there's no way this is good for any of their targets, though. Edit: Kolpa makes a really good point! This seems like a really good counter to SWATting, where the claim is that someone is holding hostages or something -- this could pretty effectively demonstrate that to be false if th…

How would a stick figure images help a SWAT team validate that they're at the right house?

This could only help them by giving them a clue about where to point their guns once they bust down the door.

If you could publish evidence of this phenomenon, the public would be very interested.

This seems nearly identical issue; why would you suspect the vote would differ?
