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.

Wild amount of confidently incorrect here.

For starters, what you describe tracks other electronic devices. That’s neat, but this new stuff is tracking bodies of interference. Meat bags. The fixed antennas and beam forming have given stereoscopic vision to interference identification on Wi-Fi routers. Before, it just saw an SNR spike between the router and TV, but it couldn’t tell if it was a cat up on the counter or a crowd in your living room. Now it can. Now it’s able to tell when something the size of a human walks past your ring camera without having any access to that camera.

You’re dumbing down old technology with interpersonal wording. Like it’s the first time people figured out how to read frequencies interrupted by bodies of things…

It’s 2026 and you’re reminiscing on SNR being a side effect of general proximity like it’s 2006 and clean direct signal is how comms still work.

The fact that this is now a household product for the masses… Catch up.

Edit; Sorry. Am learning from my inbox that this is a new highlighted thing to people. Was being harsh in hindsight. Thought it was common knowledge so was sharing further common knowledge.

Your first post wasn’t vague at all. You very clearly put the word ‘track’ right in front of the word ‘devices’ because you were discussing tracking devices. You were discussing something entirely different than triangulating interference. I think you might still be confused about what this product is.
