paired with my phone in my pocket. If I was taking photos it would go out
through the phone.
Like I said in my comment, I view this as the first steps in a suite of countermeasures, not all necessarily through the Wifi protocols.
I can reasonably imagine that stores or restaurants may create internet free zones, where some technology jams your phone in your pocket, as long as you are within the private premises. Kind of like now, where you can only connect to Wifi if you're reasonably close, the jammers would be localized. Moreover, since every measure invites a countermeasure, there would be other tools that prevent other technologies you might carry from working, once loopholes around the phone jammers become exploitable etc.
As a technology geek, this interests me, as well as knowing what sorts of things will be available when I truly need it. I don't care if this particular Wifi method is slightly niche.
