With the introduction of mobile cell phone jammer, you can disable mobile phone jammer devices in the classroom and focus on your lessons. I have used a mobile phone for a long time, so I need a high-power wireless module. It can interfere with important wireless communications, such as wireless. In order to ensure the barrier effect and long-term stable operation, it is necessary to avoid the strong electromagnetic environment. When you are not using a portable mobile phone jammer, you need to turn off the power for a period of time. When used outdoors, waterproofing is very important. Do not disassemble the antenna while the jammer is working, otherwise the shielding effect will be affected. The actual shielding range may vary depending on where you use it. An effective enclosed area is a circular area centered on this area.
From now on, you will be observed. Does this sound great to you or is it creepy? Take a closer look at the stranger on the other side of the hall. He looks like he is using his smartphone to chat, but in fact he is using a special app to take pictures of you. That is just the beginning. At a meeting on Tuesday morning, when you were joking about your new boss, a colleague’s smartphone was quietly placed on the table, and all the sentences you said were recorded. Later that night, when you flirted with the waitress in the restaurant but made an innocent joke, someone recorded the entire interactive video.
