It goes without saying that cell phones should not be used in class, but for students who won't stop using cell phones, even if they are careful, use cell phone jammer to use cell phone radio waves in class as a measure. It is reported that the high school teacher who was banned has been suspended.
Dean Liptak, a teacher at Fivay High School in Florida, has been suspended for using a distraction device. Mr Liptak was suspended for five days without a fine after the local school board forcibly blocked students' cell phone communications, posing a serious risk to students as they would not be able to make emergency calls such as 911 in an emergency.
