Cell Phone Detector Project Block Diagram User Large And Medium Exam

The cell phone jammer standard is very widely used, and it is often used in schools, used in daily classroom teaching or in large and medium-sized examinations. In fact, it is because many teachers are tired of trying to stop students from sending messages, playing games and online in class. Because verbal obstruction will have other effects, some students will still use their mobile phones quietly, ignoring the courses the teachers say. content. During the exam, in order to get a high score, I will try my best to answer it. It may have been a small note before, but now a mobile phone can check it at will, and the same type or the same question will be displayed on the interface. happen, and get an accurate answer, which is a very unfortunate situation for the students. Therefore, using Cell Phone Detector Project Block Diagram in school or very needed, at least allows students to study well and use their own abilities to consider, even if the test results are not satisfactory, they are still their true self.

It is easy to understand that the frequency of Cell Phone Detector Project Block Diagram violates the frequency of the mobile phone receiving the communication base station. There is a competitive connection between the shielding and the communication base station. If the signal interference signal strength is lower than the output power of the natural environment communication base station to the wireless channel of the mobile phone, then the signal cannot be shielded, only The signal interference output power exceeds the output power from the communication base station to the mobile phone to ensure reasonable shielding. Therefore, all mobile phone jammers will show different shielding distances when used in different signal environments, and mobile and China Unicom Telecom will be different because of the relative density of communication base stations built by these three operators. Both the communication base station direction and its communication base station output power are unlikely to be consistent.
