Build a Faraday cage into the walls so that only wired connections will work. Boom, no bans required. Actual necessary calls go through the office landlines, like they did in the 1990s. (Probably impractical, especially given the refit required for existing buildings.)
I can think of an America specific reason to not block all communication with the outside world in a school. Even if every room has a wired landline that worked and was accessible to students and teachers
That's because you lack the political will to fix the actual problem, which isn't an issue anywhere else in the world and has absolutely nothing to do with communications.
There are still windows, assume they are in classroom. There are RF blocking windows but those are quite expensive, and lose function as soon as you open it for airflow.
They do make RF blocking paint, but it's very expensive and I have no idea if it would be enough to fully block microwave signals.
