The appearance of mobile phones has greatly facilitated people's lives, promoted the completion of work and study, and brought in the connection between people. But sometimes over-reliance on mobile phones will only make mobile phones a hindrance, a negative reaction. Especially for students, especially during the stressful study period, if they rely too much on mobile phones, they will waste their studies, or even retreat if they don’t advance. Nowadays, many training institutions can use cell phone jammer in teaching places in order to increase the admission rate.
Nowadays, there are more and more training institutions. There are training institutions for postgraduate entrance examinations, as well as training for upgrading to undergraduate courses, and training for qualification certificates. These training institutions often take the form of covering the score line or enrolling when they charge fees. As long as the student pays a certain amount of training fee, the institution must promise the student. Of course, as long as the students are promised, they must be well-targeted to train them, but the students must also take action and cooperate with the training of the training institution to increase the admission rate.
When students are studying, the headache is not paying attention to listening to lectures, that is, they are distracted and always use their mobile phones. If the training institution adopts a mobile phone signal jammer, then when teaching, students can only listen to the lectures attentively, which can increase the training institution’s enrollment rate and win a good reputation.
