With the improvement of our living standards, middle school students are usually their own cell phone jammer or other electronics. This situation made the school management very difficult. The students stay up at night, use their cell phone text messages, surf the Internet etc. During the day, the whole class yawns, the students bow to sleep. To cope with this phenomenon, some schools are installing numbers of cell phone jammers to shield the cell phone signals stopping cheated during the exams. The problem is that all the students were better, but the neighbors near the school disagreed, calling the mobile operators one after the other.
The neighbors near the school were very depressed when they arrived in the evening, their cell phone had no signals, but the signal was pretty bad and a lot of noise on the phone. Only when they complained to mobile operators did they understand that it was only a matter of the cell phone disturbing the school. The director said they initially just wanted to block the cell phone signal, just like the government agency meeting. And when they installed it, they ran the test and never expected that it would cause so much trouble to the neighbors. He indicated that they had already turned off the jammer and were apologizing to the residents of the area.
In fact, the school also has its difficulties. School enrollment was not good, so they can only rely on strengthening management and building the school spirit. But the current students are very difficult to manage. Taking into account the use of cell phones, parents want to buy a cell phone so that children can stay in touch for convenience. But using cell phones in school causes many problems like falling asleep in class, inattentiveness, etc. So far, the only way to take school was to confiscate your cell phones. Whereas, student didn’t care much about a cell phone that was several thousand RMB. You would quickly buy another one to use. That was just address symptoms, not root causes. The school had no options so they thought of this jammer.
Operator communication frequency range is allocated by nation, Any unauthorized profession, interference, violation of the use of the band are not in accordance with the provision. The school may use this cell phone jammer during the college exam. Government agencies typically use jammers when they meet in a meeting room. It is a small force and no affection for closeness. You have to go to Radio Management Committee for registration, if you want to shield the signal, after getting permission, you can use it. Otherwise you will break the radio regulations. Can we only block the target persons but not influence the residents? Can it be true from a technology standpoint?
By operators to achieve this purpose is impractical and certainly affects the neighbors. In some specific cases, if we lock the student phone number from the backstage, student phones will be on hold. That sounds like a good ideal, the problem is that it is difficult to accredit. Students have no credit, if there is no approval, the operators have no right to do so. The good news is a technology that may be relatively effective, which is to scan the numbers to find out which students are using their cell phones and to do point management. However, this technique is not open to the public and is mainly used for the public security department. It is therefore very difficult to shield the mobile phone signal from the technological aspect. And that may be the problem other schools are facing. How we have to deal with this will probably require a more mature and sensible program.
