Ms. Li, director of the Suzhou Middle School principal's office, replied that the school installed mobile beacons for classrooms on weekends, up to three. “The drone jammer mobile phone can only be activated during the test in order to prevent individual phenomena. Students unconsciously organize the testing standards to ensure objectivity and fairness cannot be in the classroom and used in the yard. Wu Tianyi, a lecturer at Soochow University's School of Education, said that education should encourage the achievement of educational goals. "Playing cell phones and games in the classroom is serious. To disrupt educational goals, installing bluetooth signal disrupt in the cell phone signal in the classroom can stop this behavior and get education back on track. I strongly support this." He believes the students do not have enough civic skills. Now the school takes on the role of guardian, protecting the basic interests of the students and can give students the right to temporarily suspend school. "
The Pentagon was mysteriously testing a technology that could block GPS over a large area. This function can also be used in the Nellis test and training area of Hongqi 18-1. Eye contact and distance affect GPS users (especially other aircraft operating well outside of the training area). The Department of Defense will conduct a variety of combat operations as part of high-end exercises such as GPS jammer, demonstrating the seriousness of the threats posed by these new electronic warfare tactics. It's interesting if the U.S. Air Force admits that the technology will actually be used for red flags after the exercise is complete, but considering that large numbers of positioning, navigation, and timing (PNT) will result in GPS signal loss. In the case of large-scale military exercises, these negotiations could become more frequent in the next few years.
