Put the test room signal jammer in the right place
Signal jammers in the exam room generally appear in the front and back of the classroom, and traces of such shielding devices will be found when entering the classroom to prepare for the exam. In some respects, it is not just as simple as simply blocking cell phone signals, but more to give students a chance to compete fairly. At present, people's living standards are constantly improving, and their living habits are inseparable from mobile phones. Excessive cell phone use not only affects vision, which affects some students, but may also affect academics. Nowadays, many students mostly have mobile phones, lack self-control, indulge in games, novels, and even use mobile phones to cheat in exams. Since the emergence of some signal interference devices, the phenomenon of some students using mobile phones in school has been cracked down, so many schools will choose the signal jammer in the examination room to control.
Send the interference signal of the specified frequency band to block the mobile signal received by the mobile phone, so that the mobile phone cannot connect to the network, and cannot send and receive short messages through the mobile phone, so that the original message cannot be identified, so as to achieve the purpose of shielding. Now, signal jammers in the examination room are also used in many places, and many people are familiar with them. Shielding equipment with high power may cause no network signal in an area, but it will not affect the use of other electronic equipment at all. The test room signal jammer should be used reasonably and used in a reasonable place to avoid accidents.
