Recently, the School of Animal Science and Technology of Yangzhou University conducted a survey on the use of mobile phones by college students, and found that nearly 80% of the students in colleges and universities have the situation of using mobile phones during lectures, and most of them are chatting on the Internet and visiting social platforms. For such a situation, the school will install Block My Cell Phone Number Caller Id into classroom teaching in 2021. I think it is not the best way for a college in Yangzhou to use cell phone jammer to block students' mobile phone signals during the class period. First of all, using a mobile phone as a modern communication device, you can easily communicate with others anytime, anywhere, especially in some special emergencies; as a data transmission terminal, the mobile phone can accept the Internet resource communication of satellite signals. In the teaching environment, this can undoubtedly play a catalytic role. Naturally, the use of mobile phones in classroom teaching in colleges and universities is a double-edged sword. School leaders should actively carry out management and treat students correctly, so as to highlight the humanized services of colleges and universities.

Nowadays, there are more and more places where Block My Cell Phone Number Caller Id is used, but most people don’t know how it works, and they mistakenly think that the higher the output power of the mobile phone signal jammer, the better the jamming effect, but this is not the case. For example, in an indoor space of about 300-600 square meters, choose a mobile phone signal jammer that can interfere with about 800 square meters. In fact, you don't need to choose such a big one, it's not that the bigger the power, the better. The output power of the mobile phone signal jammer is always within a safe range. When some customers start the signal jammer, the mobile phone still shows that there is a signal, but the mobile phone cannot make a call, but some do not display the mobile phone signal. Text out. In my opinion, the closer to the signal has been shielded, and the farther is not shielded. When encountering this kind of equipment, special attention should be paid to it. It may be that the function of the equipment is attenuated.
