alt Hacker NewsNo need to ban phones, just coat the walls in magnetic paint and install faraday cages on the windows.

Jamming cell signals is illegal. There are good reasons for this such as people who are on call or people who need to call 911.
The only way around this is to build somewhere that happens to have no cell reception.

Intentionally interfering with 911 would probably be a poor decision.
