According to the requirements of use, the transmit power of the existing Cell Phone Blocker Applications ranges from 1W to 480W. How big is this transmission power? In contrast, the transmission power of GSM mobile phones is 2W, and the GSM macro base station is generally 20W to 40W. The shielded transmit power for general exams and conferences is between 10W and 60W. Generally speaking, for general testing and small meetings, choosing cell phone jammer with a transmit power of 2W-10W can achieve good results. However, from our survey of large schools and important conference venues, many places tend to pursue high-power shielding unilaterally.
For example, in a school with more than 20 classrooms, each equipped with Cell Phone Blocker Applications , choose a transmit power of 30W. In addition, after the exam, due to inattentive use, there are often cases where a small number of screens are not closed in time and are sent out for several weeks. Especially in an elementary school, the monitors were not turned off for two weeks after the exam. Before we could find that place, we found the screen turned on and sitting on the student podium! Let's all sweat! Now many young people have to stay up late. Why? Because there is a lot of entertainment right now. Cell phones and wireless networks are especially common. As long as there is a mobile phone and a WiFi network, many people can easily pass the time, including chatting online, playing mobile games and so on.
