Re: What about wireless signals?
Won't work. The WiFi Detector Van would spot them!
HAHA! j/k If they can't keep the inmates from getting cell phones, what's to stop the inmates from building and running their own satellite uplink, or point to point microwave ground relay station? Or a super-compute cluster made of bum-smuggled Raspberry Pi systems all running out of what appears to be a broken microwave oven? Or rooftop mounted, high-power, directional WiFi antennas that they use to break into neighboring, innocent networks and secretly steal their Netflix passwords so they can watch all the love and drama movies that would make their watch lists look all girly? The mind wanders, I mean wonders, it wonders. Keep it together, chaps!
