I imagine that there might be a desire to see trough walls that are taller than what a handheld device would be capable of reaching…like if you had to see through the walls of the 40th floor of a building from the ground. Aside, this thing is horrific and doesn’t need to be made. We need privacy laws.

Anyone who can receive the signal from your router can see through the walls. Your router doesn't know where you are in your house.
The article probably answers your questions if you care to click it.

It’s about criminal charges, they could not use this without a warrant. Mass surveillance is something else, the government will do what the government wants to do.
The cited case was regarding a person suspected of a marijuana grow. The police used thermal imaging without a warrant to get a conviction. The Supreme Court determined it was considered a search by the fourth amendment (5-4 decision, btw). That would be similar here.
JohannesOliver t1_iv82oju wrote
Absolutely not. GCHQ does the same stuff the NSA does, but your overt surveillance (CCTV and the like) is significantly more than the US has. I think they probably like that the US gets all the publicity though.
In the US the cops have to ask private citizens for CCTV footage much of the time. Ring kind of let them in without doing that, but it is still a private entity.

You mean that they would use parallel construction after knowing what they know after using it, and wouldn't tell you they used it. You wouldn't know they used it.

Maybe, if they were able to. For what it is I think that could be difficult though.

I suspect the writer misunderstood, and the cost is for the custom electronics attached to it. That will add up to about that much (less if you import straight from China). Those ESP boards are dirt cheap and quite versatile.
Orcwin t1_iv86lvy wrote
No. It will be able to see which devices are connected, not where in the house those devices are. The concept from the article has multiple radios, and can therefore do triangulation of the received signals.

It triangulates Wi-Fi signals, that's all. It does not detect anything visual or even physical, just where sources of Wi-Fi signals are. It does this by seeing the difference in amplitude/strength of the signal depending on where it moves.
It's cool that they bought a drone with Wi-Fi for $20 and the fact they're so cheap now, but beyond that... nothing here is new or even clever.

Using the drones WiFi to call out to your devices and their responses include distance. all a drone would need to do is do fly the perimeter of your house making multiple callouts and then it would be able to make a fairly accurate guess where everything is based on all the TOF calls.
Your router is capable of the same thing but it doesn't tend to move. Wifi triangulation happens in lots of places. Casinos and even in big box public stores like Walmart and Target. They aren't using drones to track you, instead use their multiple antenna's to see which area's of the store you visit.

No it doesn’t actually see through walls. It can approximate the location of wifi devices. You can do the same thing by walking outside the building with the device in hand. Drones make a lot of noise and it would probably be more stealthy to just walk up to the building.

Really? Horriffic that it can see wifi signals and pinpoint them. This is old tech and the article is just sensationalism.

It depends on how accurate of a fix you want. I have a old router that could do fairly accurate Wi-Fi triangulation but the accuracy decreased as the RF clutter increased (e.g. walls between the router and the device).

Actually you can use wifi signals to get a rough layout of a room. Not with this kind of setup, you would need a directional antenna.
It’s been demonstrated by a bunch of nerds messing around with a home made radio telescope years ago.
Wifi uses the electromagnetic spectrum. Just like light does. Except it can pass trough walls. So you can use it to “see” into a room but because of the wavelength is so large and it will pass trough a lot of stuff you will mostly see things that are highly reflective to wifi and other sources of electromagnetic radiation with the same wavelength.

Well water reacts particularly well, and we’re mostly water. So it can be used to track people inside a building fairly well. And because wifi is providing the “active” part of this active scanner, it can be done very covertly. It would be hard to detect that someone is monitoring your building.
But that isn’t what this article is about.

They can triangulate the location of wireless devices without line of sight, by repeatedly measuring 1-dimensional distance data and sampling from multiple measuring locations. Kinda like how GPS works. The data is positioning only, and indirectly/approximately derived.
I wouldn't call that "seeing through walls" as if it's an x-ray camera. I might say "it can see the 3d position of wireless devices through walls, but no visuals, it can just see the spots the things are at."
They can also reverse-engineer what the device is likely to be, by cross-referencing its unique MAC address with the manufacturer that has reserved those addresses. So, something by Apple is probably a computing device or an AirPort router or whatever.
I dunno, man, this headline feels way too hyped up. A persistent person could definitely profile where stuff is in your building, but that's a hell of a lot of effort to case a joint than just traditional means, IMO. Sounds like the kind of stuff only spies would care about, or organized crime maybe.
myalt08831 t1_ivarbmb wrote
It's not the amplitude of signal strength. Time of flight uses a precise timestamp in the data packet from the exact moment when the packet is emitted, and you use the time elapsed between the initial timestamp and when you got the message, divided by the expected physical speed of propagating the signal through space, to estimate distance from the transmitter to the receiver.

No he's saying his router can already "see" everything going on in his house (from a wifi standpoint) so if you get access to it, you get access to the same information.
And the answer is, not quite, as you can't get multiple points of measurement of directional signals from a router in a single spot.

Just wait till you hear about Apple indoor positioning….
It works in any iOS app as well as websites viewed in Safari or other WebKit compatible browsers on iOS devices. “Coverage of indoor positioning can be increased by simply installing additional Wi-Fi access points and enabling beaconing mode. The access points do not need to be connected to any network and their SSID can be hidden so they are not discoverable.”
