Yesterday afternoon, the reporter rushed to Nanjing Forestry University and walked into a classroom in a teaching building. On the walls on the upper and lower sides of the blackboard in the front of the classroom, journalists noticed that there were two small boxes and a round "black eyeball". LOGO, the small box below is dark blue, and the logos of all three major operators are printed on the chassis. More than a dozen students in the class have finished school. They told reporters that the four boxes and two "black eyeballs" in the classroom were just installed last week, and it was not clear what they were used for. However, just last week, a student from Huaiyin Institute of Technology posted a post on the community forum, saying that his cell phone signal in his dormitory was poor. At that time, some people were installing these small boxes in the adjustment class. The experimental small box is Build Your Own Cell Phone Jammer The self-taught students in the middle class here are most common in the fourth grade students. Most of them use mobile phone numbers. The data signal is very good, basically indicating that the situation is full. cell phone jammer After connecting the Power socket to the small dark blue box on the wall in front of the classroom and turning on the Power switch on its left, the reporter found that the data signal of the self-taught students in the class quickly weakened until it subsided. When a journalist dials any student’s mobile phone, there will be a voice announcement: "The number you dialed is on standby." Based on several experiments, the journalist inferred that the small box on the wall in the classroom is a mobile phone signal jammer. . For that "black eye", it should be similar to the "look" of the camera on the street.
When the data signal fades, users can still play games, but can no longer access the Internet. News reporters have learned that the current college students "playing" on mobile phones, not many of them play games, basically "swimming" on the Internet. Knowing that the camera and Build Your Own Cell Phone Jammer are placed on the wall, the first reaction of the self-study students in the classroom is that the college is looking forward to taking this opportunity to severely crack down on the "mobile party" in classroom teaching, that is to say, do not go to class and listen carefully, but just bow your head and "play". "The student on the phone. Some classrooms in the teaching building have already taught.

However, the cameras and mobile phone jammers on the walls in the classroom are still not turned on. Experts and professors told reporters that the college has not issued a notice at this stage, requiring them to turn on their cameras and mobile phone jammers when they are in class. The renewal and reconstruction of the safe cell phone jammer serves as a master's degree examination room "The students are misunderstood." The installation of cameras and cell phone signal jammers in classrooms is not at this stage to prevent students from learning to watch mobile phones. "
