not a lot i don't think? it's sensing movement of objects (likely with specific properties (reflectivity) as well), so just cutoff by cross section/speed of movement will deal with that. it's not like movement sensor which on or off
We’re so cooked man
Yeah man, tell me more about CHYNA being an Orwellian police state and shit.
thanks for the blanking. Seeing this go around elsewhere, wild how its still cool to openly shit on ND people
dunno why it's hard to use tinfoil hat wearers, it's a symbol for this exact shit :(
Because what will a person with that disorder do? complain about it? because everyone will side against them, everyone will see them as the irrational person no matter what they say.
Tbh, tinfoil hat wearer (if interpreted literally) also refers to people struggling with health condition, but it maps so much closer to this scenario, while people struggling with schizophrenia are just not.
Being nicer it would be like "cybersec bros holding gun to printer undefeated"
can I ask what it said originally?
I'm guessing something inflammatory towards people with schizophrenia
2 meters error (assuming it means radius of 2 meters) is like my whole living room lol. This kind of sounds like “well the research went nowhere but the thesis to be submitted”
good enough for hellfire missile tho. Or pinpointing a room in a building
It requires a lot of nodes! Like if you’re placing 6 wifi end points in every room that’s pretty bad opsec even without this.
I have a smart light that interacts with wifi, add one more and you could use them to triangulate at least a rough position possibly. Enough to tell if someone is in the house at least and maybe an estimate of how many people. Sci-fi dystopia shit really if it is truly possible.
“With only 6 wireless nodes we can make an algorithm to determine a napping person is in or near the foot of their bed” is so funny.
if i ~~read~~ skimmed through correctly, nodes in that case are basically wireless devices (so iot perverts + phones/watches/audio/tv).
so the opsec here doesn't really change much. prefer wired whenever possible and don't fill your house with iot. how useful is this method if the person they want to track only has two broadcasters (their router and their phone)?
Whether they're in their house or not is all that's really needed for any monitoring purposes I can think of.
Of course, if you've compromised their 6 damn wireless nodes, you also know that they're home when their phone switches to wifi.
there's way easier ways to know if someone is home. stakeouts, fake pizza delivery, tracking your car

I predict that, within my lifetime, the US will precision drone-strike US citizens on American soil.
several years ago they got that guy in dallas who was icing pigs with a bomb on a glorified RC car, does that count?
We've tried icing pigs to some success, but has anyone thought about pigging ICE?
if they keep running a round in masks with no ID there ought to be some really cool blue on blue any day now 
Signal jammer is going to be a necessary part of the infantry toolkit for anything that may involve defending a building.
With this technology you can broadcast a wifi signal as a sort of radar ping, then have the locations of all living things in the building mapped to within 2 meters of their location.
Map that to an AR headset and the infantry has real world wallhacks and you know how much of an advantage that will be.
idk how big your rooms are but being off by 2m would have me outside or in a hallway or in another room rn
In Ghost Recon you have to throw a special grenade to see the enemies through the walls
Our best bet at stopping this is getting ankle bracelet companies to go to war to protect their market share.
becoming multiple cat person to own the isp watchers
Comrades, we must practice vigilant opsec
Ourdoor cat Hexbears stay losing.
Isn't this basically what they did in The Dark Knight? You know, when Morgan Freeman was so horrified by the implications that he made the whole room self destruct afterward?
i think implied tech was that the phones were emitting noises to be like mini sonars (which also works, but requires hacking the phones). At least there was some pinging animation, if i remember correctly
Snowden specifically mentioned that when he leaked his information while talking about PRISM.
I can not stress enough how important and easy it is to just have your own router. Please don't use the ISP provided router its a waste of money, and a privacy nightmare. You can get a much better one for pretty cheap instead of renting one from them.

Another use I thought of, once it's thoroughly proven it could be used as criminal evidence. "You claimed to be home sleeping by yourself but your signal data shows someone left your room at 1:00AM and returned at 3, just when the crime occurred." They can track you with your phone already but the trick of just not having a phone on you wouldn't work. Wired life wins.
The post on .world links to one of comcast’s pages about it where they explicitly say
“Comcast may disclose information generated by your WiFi Motion to third parties without further notice to you in connection with any law enforcement investigation or proceeding, any dispute to which Comcast is a party, or pursuant to a court order or subpoena.”
So yeah, absolutely could be used against you
well, what xfinity is peddling is solved by just using openwrt/at least your own router/access point
You already get put on a watchlist for downloading Linux
called peer ip? everyone on the list lmao, doesn't mean i will put ring camera in my toilet.
Is this confirmed?
what does RSS stand for here
received signal strength
username checks out
here's a paper from 2013 i found about how this works
No more wifi, only wired connections
Reminds me of some new research that each person’s breathing pattern is like a fingerprint that can identify them. An ordinary smartphone microphone is sufficient

RSS in a wireless network. Don't breathe this.
I always wondered how they scanned for life signs in Star Trek and now I know
