The school classroom is a place of study. Now, with the popularity of smart phones, you will find that in university classrooms, students can be seen playing mobile phones, playing games, and sending text messages to each other everywhere. The classroom used to be completely quiet. If you were a teacher, how would you feel if you often encountered the above situation in class? This not only affects the progress of the class, but more importantly, it affects the learning and growth of children. Painful, so how will you deal with such problems? This is a piece of news that happened in Florida: On March 31st and April 1st, Dean Liptak, a science teacher at Fivay High School, aimed to keep students focused and quiet in the classroom. He used a cell phone handheld jammer to block phone signals in class and was sentenced to five days of unpaid suspension.
One-key mute: Realizing the dream of mobile phone jammer will become possible. It is assumed that in the future, aircraft will be divided into telephone areas and non-communication areas. Just like on a train, you can choose between a cell phone area and a rest area. The principle is simple. In the communication area, mobile phone reception increases and you can freely talk with other people. In the rest area, you only need to turn off the mobile network or block the mobile phone signal, and the rest area will become very quiet.
There are such tools that can disrupt mobile phone networks in specific areas and block mobile phone calls by clicking a button. This is a jammer or cell phone blocker. There are various professional interference devices. Some people think that the jammer has destroyed the mobile network in the environment. For example, in movie theaters, theaters or churches, the device can be used to enforce the required mute effect, but it may affect emergency calls. Just install a public phone here.
