Given three WiFi transmitters and three aligned receivers, can
we detect and recover dense human pose correspondence in clut-
tered scenarios with multiple people (Fig. 1 fourth row). It should
be noted that many WiFi routers, such as TP-Link AC1750, come
with 3 antennas, so our method only requires 2 of these routers.

It's like sonar, not a laser. You're not just measuring a single point of reflection, but a whole bunch at the same time. But yeah it'd be easier with more antennas. Good thing everyone has cellphones LOL

It's been real for a long time now, the people who wrote that movie probably knew about it. I saw papers on this idea at least a decade ago

the advertising firms presentation talking about using wifi to estimate what the users wealth level is, what they do while gaming as they're presented with stimuli was from 2017 https://imgur.com/a/rhFuj

I think not knowing where the devices are in relation to each other would harm the ability to infer objects from the signals, though. >All above results are obtained using the same layout for training and testing. However, WiFi signals in different environments exhibit significantly different propagation patterns. Therefore, it is still a very challenging problem to deploy our model on data from an untrained layout.

Ok looking at the paper they use two routers (one transmitting and one recieving) both in a huge open room with three antennas on each one, it doesn't really seem to imply this level of observation is remotely possible through walls or just because you're next to a phone.
Even in this experiment they still lacked a 100% success rate despite nothing really being in the way, and I'm going to assume they need access to the data going into/out of the routers and likely the receiver too.
I don't think the gubbermint can fully map you jerking off through walls yet, but if you intend to go schizo mode and die in a police shootout its probably a decent idea to at least put your phone in a faraday cage.
>>106245613 >Does this insane bullshit work outdoors too?
Don't see why not.
But you need to have transmitters and receivers in LoS. If it is outdoors why not just have a fucking camera? You could even set up the computer vision shit on a dinky camera and have it email you whenever it detects movement.
