At Chengdu University of Science and Technology, classrooms in the new building are equipped with “mobile cell phone jammer“, which are a good way to prevent students from using mobile phones in the classroom. Is the school really trying to block students’ cell phone signals? The watch was found in an empty classroom in the second teaching building of the school. The watch is closer to the blackboard on the seemingly “black” wall of the instrument science and technology. The instrument is also located on the automatic switch and displayed by Internet users. That is gsm jammer. In this empty classroom, the power cord is not connected to the signal shield and the switch is not turned on. Therefore, the reporter’s mobile phone signal is normal and the network can be used normally. The reporter will also find several floors in the second classroom building, both a school classroom and an empty classroom. Cellular signal is not affected, you can receive information, make calls and use the Internet.
