This is a most excellent place for technology news and articles.
I mean, I obsessively hardwire all my devices, only my phone uses WiFi.
This just gives me a reason to skip using a WiFi Access Point entirely and just routing my phone through my home network via my Wireguard VPN which I already do for adblocking.
Doesn't help as much if you live in a bunch of cramped apartments and there's a lot of WiFi around you though.
The AP is what does the tracking. If you build your own, and only you can access it, then it can’t watch you. VPNs don’t solve any of this, it’s not about a device being encrypted or not.
Would carrying around some sort of Wifi disruptor help against this? It would likely have to be a passive persistent effect, not something like an EMP (but those we can reserve for particularly annoying snoopers).
I mentioned this in a another reply, but you just need a microwave oven basically :)
Super now I just need to find one of these in portable form factor. And a good battery.
I was watching a video the other day that was showing WiFi sensing using TOMMY which uses channel state information (CSI) - something this article describes as the previous approach. That was already quite impressive, although not nearly as powerful as this teaser hints at.
