teachers confiscating phones can be forgotten. The same goes if they take the battery away as well. Disrupting the teacher wastes time for the entire class, so I’m wondering if these jammers are being implemented to prevent texting and calling during/between classes instead of the original method of dealing with cell phone disruption.
Average devices have a range up to 150 feet, so many would be needed for larger schools. Do you think they help you focus during class instead of waiting for that message about from your friends?
These devices do exist and only jam the cell signals/bands. There is a phone in every room for emergency calls and hall monitors or other staff members use radios of instant communication to administration in case of an emergency.
