The PDAs figure out their locations by comparing the strength levels of signals traveling from the devices to various Wi-Fi antennas. No GPS Required. Article from Salon here..."
Gee, instead of leaving this tracking device in my desk, I'll take it with me when I decide to do something wrong.
If you wind up getting caught because you have one of these on you, then its you're own fault. Unless it's actually wired to you, then just leave it at home. This isn't big brother stuff, more like his little cousin's.
