Many people find it not a solution to have a jammer in their school, but because children have access to the internet in several other places, such as at home or in the city's open Wi-Fi zone. Some people find it a good initiative. Adolescents do not have sufficient maturity to properly use the Internet. You may be exposed to content that they shouldn't be, either out of curiosity or under pressure from peers. Installing jamming devices is a very good initiative to prevent anyone from making such mistakes unintentionally.
Very convenient signal jammer function
Classrooms are usually not very large, so a cell phone blocker is recommended. This is very convenient to carry and use. All you need to do is press a button to turn it on. Sure, you don't have to worry about an emergency where someone needs to make a call. They can leave the classroom and make phone calls without disturbing others. Alternatively, you can switch off the jamming unit if desired.
There are devices that interfere with the phone signal. In essence, it pretends to be a base station, not a base station. The problem with that is that it disables emergency calls. Theoretically, you could implement something that switches the phone to "silent mode" when the phone is in an unauthorized location (because the operator always knows the location of the phone). However, no one has proposed this as a product or standard, but it's not particularly difficult. You probably have to pay for it because you are a movie theater owner or a restaurant owner.
Mobile phone obstruction
Today, almost every student in the school owns their mobile phone. To make matters worse, mobile phones have become a "weapon" for many students to teachers. Most students will find that they are surfing the internet using their mobile phones during the lecture. Many students tend to listen to music and play video games in the classroom. Sudden ringing of a cell phone during a classroom lecture is often distracting. To make matters worse, it helps some students cheat on exams using their mobile phones ... A new phenomenon, "cyberbullying," is text messages and social networks when students need to pay. Attention to lectures has been reported to refer to electronically afflicting others through.
