As we all know, we are now living in the modern age of electronic information: it is very easy to have a mobile phone (mainly a smart phone) for unlimited texting or calling, so it is not difficult to imagine a classroom. Most students are busy sending text messages, surfing the Internet, and listening to music instead of attending classes. In this way, the mobile phone seriously distracted the students. Therefore, if teachers and principals want to prevent this from happening and get students to refocus, then the easiest and most effective way is to install cell phone jammer in the classroom.
Not many people know that law enforcement agencies can use GSM frequencies for many surveillance purposes. For example, they can obtain private data from your phone with the help of a mobile operator. Although they do deserve guarantees for such procedures, they usually don’t do so, thus violating your privacy expectations. In addition, some law enforcement agencies may touch your phone to eavesdrop on all your conversations. In this case, you definitely need a GSM cell phone jammer to block the GSM signal. However, these are not the only problems you may encounter.
