I believe you can get this kind of tracking in the same room as the router. Perhaps thankfully, I doubt you can get anywhere close to this level of precision if it's in another room.

Still, I bet you can probably at least determine presence and direction through a wall. The signal is designed to penetrate.

If implemented for consumer VR, there will likely be a dedicated "base station" putting out a clean signal in the room you are using for VR. It might not even be an actual Wi-Fi carrier signal ... i get the impression they were experimenting with "off-the-shelf" wavelength bands to see if the technology was feasible.

I would expect a consumer version of this to use a non-interfering frequency that was close enough to the Wi-Fi range that they wouldn't have problems with licensing with the FCC. Or maybe even use an ACTUAL Wi-Fi band ... and then let the installing user decide which channel that is (one that wouldn't interfere with their existing wi-fi).

This is just the authors showing off technical chops. I don't see this being commercialized as we have easier ways, with cameras, to accomplish the same thing.
