Yes, but the WiFi wouldn’t work either. Our kids use their Chromebooks all day long

our school has a “phones stay out of sight” rule that seems to work pretty well

They don’t have to, there are already phone blocking systems in place in schools here in Scotland.

I mean technically yes but intentional cell phone jamming is illegal to some degree in most states due to it being viewed as a security risk to cut off people’s ability to contact emergency services like this

This is a huge no-no with the [FCC](https://www.fcc.gov/general/jammer-enforcement). Can’t install anything with the intention of blocking cell phone signals.

I have studied in rooms with a full faraday cage installed, including the door, it does work. Wi-Fi router in the room works fine for authorised devices logged in. Not cheap but doable.

yes, I have a faraday fabric I ordered off amazon to put up against the wall where my breaker box is to help eliminate EMF so my guitar is less noisy when im playing. I wrapped my phone in it for fun and had my girlfriend call me and it didn’t work.

You can, it is very easy and there are devices for this but the FCC will find you. There have been cases where drivers have employed these devices and were eventually found out despite being in motion. FCC does not take kindly to these cases.
