Make no mistake, this is 100% going to be Comcast's alternative to more expensive surveillance options a la Flock, or workplace presence sensor arrays.

Nope: https://www.tomshardware.com/news/wi-fi-routers-used-to-detect-human-locations-poses-within-a-room

It's gotten even more capable where it can basically act as a presence sensor through walls as well. It's not simple device tracking at all.

That was not what you should've gotten from my point.

But, yes. That is also obviously correct.

Edit: Granted, my bad for really dumbing down the wider scope of it. I re-read the comment now seeing why, when regarding the specifics of signal disruptions of a network for identifying—which is a part of IDing and tracking secondary to the actual top layer identifying—is a thing. Thought that went without saying...

Am learning this is somehow surprisingly new to people. Which is honestly the bigger concern.
