Mobile jammers in schools are becoming more and more popular, and this is for good reason. Many teachers are tired of trying to stop students from texting in class and want to know how to stop using their mobile phones in class. Students ignore lectures when browsing social networks. Some people send text messages and even do research online to cheat on exams. Although these cell phone jammer are capable of terminating cell phone communication and appear to be technically complex, you may be surprised by their simplicity, just the push of a button.
In fact, it is not only applicable to university entrance exams, but also to qualification exams, high school entrance exams, national exams, etc. This means that cheating using mobile phones has been discovered one after another. I think this method of installing mobile jammers and temporarily “stopping service” test sites is the most effective measure. A radio station license is required to install the equipment. By transmitting a weak radio wave of the same frequency as the radio wave of the notification message from the mobile base station, communication is blocked and subsequent location registration and polling become impossible, so the display of the mobile terminal becomes “out of service area”. Communication Was suppressed. We will also introduce this device around the bank. We will start to restrict the use of mobile phones at ATM corners. This is a joint effort by financial institutions to prevent criminal damages such as transfer fraud. Multiple financial institutions will jointly install equipment at ATM corners. It is used as a measure to prevent transfer fraud.
