Not without breaking several laws, and potentially putting people in danger - how do you call 911 in an emergency if the school is in a signal blackout?

  Shielding is probably bad and expensive, but is it illegal?

    Yes: https://www.fcc.gov/general/jammer-enforcement https://www.fcc.gov/general/jammer-enforcement

      That's jamming, not shielding. https://en.wikipedia.org/wiki/Faraday_cage https://en.wikipedia.org/wiki/Faraday_cage

  Landlines, voip, panic buttons. People made calls to 911 before the iPhone was invented. When I was in school every single classroom was wired for landlines and Ethernet. You can also set up your wifi networks in ways that limit certain things and not others.

    > When I was in school every single classroom was wired for landlines and Ethernet. Alright, but they're not wired now. Neither are bathrooms, cafeterias, hallways, or other place where someone might have a stroke, a heart attack, a seizure. And unfortunately, gunmen in school are a thing, and if you're a teacher, scrambling for the wall-phone while you can hear gunshots in the next room over is significantly more difficult than reaching into your pocket for your phone.

      Maybe some kind of smart network could only allow 911 calls through, and no data? If phones in schools really are bad for kids, it seems like we could probably sort out some of these objections?
