In the second teaching building of the school, the watch was found in an empty classroom. 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 cell phone 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. The cellular signal remains unchanged, and you can receive information, make calls, and use the Internet.
“This is the structure of the standardized test location.” The person in charge of Chengdu University of Technology said that the mobile phone jammer device installed in the new teaching building is a work in progress in accordance with the requirements of the standardized test room. Only the new building is being installed here. All installation work has not yet been completed. He also said that the shield will be opened under the unified requirements of the four and six exams to be held in December.
Almost everyone uses mobile phones everywhere, whether it’s theaters, educational institutions, coffee shops, restaurants, offices, or anywhere else. Today, people spend most of their time on their phones instead of spending quality time with their families or focusing on organizational goals. Mobile phones can help you in many ways, but it also distracts a lot of life. This is where cell phone jammers come into play. Interference refers to the blocking of objects. Therefore, mobile interference refers to the fact that network signals block the mobile phone, thereby denying access to the Internet, sending SMS or phone calls.
