Eli5: Would Faraday Cages block Cell Signals well enough to utilize them in a classroom setting?

Question

I.e. ‘bricking the phone’ for the students benefit

In: Engineering

Answer 1

Is it policy to allow students to have phones in the classroom? If it’s not, speak with your coworkers and boss to figure out how to maintain policy. If it is, I would petition to make a policy change. Smartphones are harming our youth in general, and especially in the classroom. Even if phones are against policy, I wouldn’t recommend a faraday cage. Wireless transmissions are highly regulated by most countries and blocking/jamming signals generally is a serious offense
