I'm assuming that this works because when the AP is communicating with endpoints in fixed locations, the AP can tell when signal quality changes as attenuators move through the space. This might work better with modern 'beam forming' APs using modern 802.11 standards, but theoretically one could constantly measure the signal strength between a stationary endpoint and the AP and observe when that signal is weaker than it otherwise should be.
If there are insufficient stationary endpoints it might not work so well unless it can somehow measure reflectivity with enough precision to know that something moved through.
Probably, yes. There was a paper on this, just a week ago: using it to identify people
