>You can see a lot of timing info from network sniffing even if you can't read it of course. That was my primary assumption. Worst case, modern phones can act as hotspots—so if your phone is owned but stuffed in a drawer, it could theoretically sense beyond that and perhaps read your lips from another room. I'm guessing any stereotypical white vans worth their salt would provide fake devices for your phone to connect to in that case. On the baseband side, perhaps Stingray setups have the potential to be more useful than commonly imagined.
