In short, they randomly emit static or noise over a wide range of frequencies such a device cannot connect to the connection it should. It’s like sitting next to the engine of a sports car, opening the hood, and talking to someone on the phone. The localized noise becomes too strong for the device to connect properly. Rapid coverage of a range of frequencies can effectively prevent equipment from working properly. A cell phone jammer is a device that prevents cell phones from receiving cell phone signals from base stations. Cell phone jammers effectively disable cell phones when in use. The unit can be used anywhere, but phone calls are especially disruptive most of the time due to the expected silence. In recent years, some large companies have also begun to buy such products.
At present, some college graduates always feel that it is difficult to find a job, but it is not clear that many companies are also feeling: it is really difficult to find college graduates with real skills. Suppose that when you are in school, the students’ smartphones have become the “third party” in colleges and universities. What skills do you use to get a position when you are employed? It should be admitted that some students in school are addicted to looking at mobile phones because of poor self-control, little experience in today’s society, and lack of ideals and beliefs. How to pull students back from mobile phones, colleges and universities should actively discuss various countermeasures and make a difference. Or “delineate hard bars” in the school rules, such as the implementation of “mobile phone-free classes”, and those who illegally bring mobile phones to class and the circumstances are serious, will be expelled as required by some colleges and universities in the United States. Or go high-tech and use smartphone jammers in classrooms. In short, as a university that teaches and educates people, it is impossible to let the phone look at the phone during class as an “unsolved problem”. It is the responsibility of colleges and universities to educate and restrain the misbehavior of students in school, and don’t let it go because it is difficult to manage.
