Since the classroom is usually not very large, it is recommended to carry and operate a portable mobile cell phone jammer that is very convenient. All you have to do is press the button to turn it on. You certainly don’t have to worry about emergency situations where someone might need to make a call. You can walk out of the classroom and make calls without disturbing others. Or, you can simply turn off the cell phone jammer unit as needed.
Mr. MacNeil has taken measures to prevent its use in the past, including the purchase of mobile phone signal jammer equipment, which will interrupt service. He said that this device is considered illegal, but no one in the United States has been charged for possessing such a device. Mr. MacNeil added that when he bought Jammer, he was discussing the issue with teachers in nearby classrooms who were fully supported. Since this mobile phone jammer is outdated, its effect is poor. It can only block 3G signals at best, and students with smartphones can still use WiFi.
If you have an emergency meeting and you don’t want anyone to participate in unwanted calls or messages during an important meeting, you can take advantage of cell phone jammer technology. This technology allows people to avoid calls and text messages without turning off their phones. Activating the technology will directly block the signal from the base station, making it impossible for the person to use the phone to communicate with other people.
