The reason the FCC is only allowing the sale of state approved routers in the US?

From what I've just read, the tech doesn't seem ready to identify people yet. It can supposedly detect hand gestures, but facial recognition I seriously doubt. But that's probably just a matter of improving the tech. See this article for more info.

    From OPs linked article...

    In tests involving 197 participants, the researchers said the system identified individuals with nearly 100% accuracy. The recognition remained effective regardless of viewing angle or how the participants walked.

    I can totally believe when it tracks a person it can tell when the same person walks by again later. But matching people with their actual identities would require a database of wifi scan data that simply doesn't exist yet.

    that's a load bearing "yet"

    Well in theory every tech possibility is a "yet", but the way I read this it seems like a person or object's interference pattern is particular to the local signal environment - not like a fingerprint a different system could recognize at the airport.

    that's a trivial problem to solve. combine this with a camera for facial recognition in a public space. then you've got wifi signature combined with the photo/video for facial recognition. then presumably you can use the WiFi signature anywhere else, even without the camera and be able to identify people.
