The technology to convert wifi signals into the placement and identity of people is getting much better. Not by using their devices, just the waves bouncing of their bodies. (There’s nothing new to the pipeline as far as I can tell, we’re just starting to get into the accuracy ranges that make it easy/useful.)
“identify people walking within a network’s range”
So it’s dependent on me walking? Good luck! 🤣
the wonder is that folks walked in different ways, and were still identified correctly. Not walking, you might be mistaken for furniture tho.
