Sometimes, if they do not arrive on time, we have to wait a long time. But now, we only send text messages or dial his mobile number. The problem is solved very simply. At that time, the Internet was not used much, so we paid close attention to the classroom. We couldn’t find much information after school. Therefore, our knowledge comes only from manuals or tests. Today, students can search for information on the Internet. You can also download the required information. Although many students do not want to participate in the course,
Therefore, the school is worried about this problem. They decided to install a mobile cell phone jammer to prevent this from happening. I agree with this idea because university is one of the most important periods in our lives. So far, we have learned a lot of knowledge and information. This period may also be a turning point in our lives. If we study hard and can enter a famous university, your life will change. At that time, many celebrities were studying hard. I still remember that when I was in university, I was very interested in learning geography and English. I spent a lot of time on these two issues.

Can they turn off the machine after school? Most importantly, the product should not affect the lives of others.
In advanced communication systems, this “headroom” is sometimes even negative (meaning that the communication signal may be much weaker than the interference signal), and the receiver can still do so. This happens because the receiver usually needs to leave a certain “headroom” between the two input signals to interpret a signal (usually louder). However, in advanced communication systems, this “headroom” is sometimes even negative (meaning that the communication signal may be much weaker than the interference signal), and the receiver can still do so.
Many commercial operators want to use telephone jammers. Restaurant owners and theaters are just two examples where customers often receive mobile complaints. It is tempting to provide expensive metal screens in buildings to block cell phone signals (which is legal). The hospital also wants to connect phones that may interfere with medical equipment. Churches, libraries, courts, and entrepreneurs hoping to increase employee productivity are all examples of potential technology customers. Major manufacturers mainly sell jamming equipment to military and law enforcement agencies and report sales, but selling equipment to everyone requires the buyer to be responsible for legality. The buyer assumes full responsibility. Obligation to buy, own or use equipment. The mobile phone industry opposes the use of these devices, and many people have invested money to put mobile phone labels on the growing problem of mobile phone users.
