It would be nice to have signal jammers pre installed next to every cell tower. You only need to jam the up link, or the signal the phone or radio is sending to the bts/tower. Trying to jam the signal the bts puts out would require too much power.
Also this way i can jam individual phones instead of every phone within range.
Activate it remotely with a 2$ wifi module maybe. No evidence no case. Self destructing circuits are easy enough to make.
I could scan any phones near me with a raspberry pi and realtek, get their frequency, and remotely jam their signals.
Hmmmm...
The fcc would eventually locate some of them, thats why id have multiples...
