Range of mobile phone jammers used in schools
So far, McNeill has taken steps to prevent its use, such as purchasing cell phone blockers, which are devices that block services. He said the device is considered illegal, but no one in the United States has been charged with possession of such a device. When buying a jammer, he talked to a teacher in a nearby classroom, and they received full support. This jammer is out of date and therefore less efficient. At best, it can only block 3G signals, and students with smartphones can continue to use WiFi. So I bought the latest multifunction jammer.
The school installed a mobile jammer in the dormitory building. This is an act of internal control, which is good. Most mobile phones are now smartphones. Many students get up all night and play their cell phones. The next day's course is very mentally deprived and affects learning. After installing the jammer, the students will not stay up late and the next day's spirit will improve.
Currently, almost every student in school has their own mobile phone. To make matters worse, mobile phones have become a "weapon" for teachers for many students. The talk found that most students use their mobile phones to surf the Internet. Many students tend to listen to music and play video games in the classroom. Often, when talking in the classroom, the phone rings suddenly and is distracting. To make matters worse, some students use mobile phones to help with cheating on exams. Reportedly, a new phenomenon of "cyber-bullying" refers to students who use text messages and social networks to electronically torture others during lectures.
So you need a phone jammer
Classrooms are usually not large areas, so we recommend using a 3G / 4G phone jammer, which is very convenient to carry and use. It can be opened with the push of a button. Of course, you don't have to worry about an emergency where someone needs to call. They can get out of the classroom and make phone calls without disturbing others. Alternatively, you can turn off the signal jammer unit only if necessary. You can buy a handheld jammer for a single space and a desktop jammer for a large space.
