    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”

          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.

        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.

    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.

    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

    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.

        Only if they have access to it. You can secure your own router, but your ISP has full remote access to the one they give you.

        Whats MOFI mobile wifi? It’s possible to buy your own regular router, and use a mobile modem. I have a thinkpad i turned into a OpenWrt router that i tether my phone to, and then it connects to a normal wifi access point that sends the signal to my other devices. So that i can turn 5G into Wifi at home. Works quite well.

          Whats MOFI mobile wifi?

          Sort of but there’s more to it. Like you, I can just use my phone as a hotspot and use its data plan for my internet access but there are of course strict limits to that. After so many GB (which I use in 2 days on a monthly allotment), I get throttled even with an “unlimited” data plan. The way I understand it is that carriers sell business level LTE/5g plans to companies that they won’t sell to individuals, plans that actually are unlimited without data cap throttling. So companies sprang up that buy these business plans from the carriers and then resell them to individuals, almost always in rural areas who have no access to broadband.

          The main thing I expect is the sim card you put in the router that allows you access, but I think the router is specialized too? Like my MOFI router supposedly switches between carriers depending on which ones are the least congested and best reception. What matters to me is that it’s actual access without throttling. Before, I couldn’t watch more than 2 movies in a month or download a ps4 game. Now it’s like I’m a normal person with real internet access. Well aside from the latency. So I don’t know, maybe I can get my own MOFI router and just pay the rural internet access company for the sim card, but I haven’t seen much about people doing that which is why I was asking.

            What you could do is just use a MOFI router from the company that doesnt use wireless and just connect it to a normal router via an ethernet cable i guess. You can always just make your own subnet no matter what connection type you have, and simply route all internet traffic into the other network from that subnet.

            But if you can find a way to just get your own MOFI router that’d be better. I don’t know much about that stuff so couldn’t say.

    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

    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
