Not possible to isolate a certain cellular area with out affecting everyone, not just the scum
“Not possible to isolate a certain cellular area with out affecting everyone”
Nothing is impossible.
If your city is in a state of war, you must take out the command and control communications even if effects everyone within that zone.
You can limit the effect to a couple of blocks by having multiply low level power jammers. Some movie theater about 10 years ago were using jamming until the FCC step in.
You can build jammers using HackRF One.
You can also use Stingray to to denied service to cell phones once you figure out what cell phone is what.
Thinking about it you can use Stingray to watch for their command and controls apps accessing the Cell data network to identify which cell phones to block.
Either way their Command and Control communication need to be taken out. If that is every cellphone and wifi signal in the area so be it.
The police have their own communications systems on different frequencies.
