Does Carbon Fiber Block Cell Phone Signal Prevents Conference Content From Leaking

The threat of recording not only comes from the voice recorder, but the mobile phone is also a serious object for recording. Nowadays, the mobile phone is almost always in your body, and you can't imagine opening the recording device when the mobile phone is buckled. If someone with ulterior motives opens the mobile phone recording software during a meeting, there is a high risk of the content of the meeting being leaked. So you need Does Carbon Fiber Block Cell Phone Signal to handle it. With cell phone jammers, you can better protect your information security and privacy. The recording masker emits ultrasonic waves with random noises that the human ear cannot perceive. When digital devices such as mobile phones are recording, these noises and normal conversation sounds are recorded into the digital device, making the recorded audio invalid. Noisy noise is randomly generated and cannot be restored, so the disturbed audio cannot be restored. cell phone jammer ​It is only effective for digital products such as mobile phones, and does not interfere with people. Because the human body does not receive ultrasonic waves, it does not affect normal conversation and communication, and it is impossible to even detect that the mobile phone jammer is working.

When taking some important exams, in order to prevent candidates from cheating through mobile phones and other communication devices, Does Carbon Fiber Block Cell Phone Signal can always be seen in the exam room. As a good helper that can effectively eliminate and prevent cheating, schools and teachers are not unfamiliar with it, but some questions are still unclear. For example, if there is a base station near the examination room, will the effect of the mobile phone signal jammer be affected? When the mobile phone is working, it is within a certain frequency range. The mobile phone and the base station are connected by radio waves to complete the transmission of data and sound with a certain baud rate and modulation method. The cell phone signal jammers mostly achieve cell phone signal shielding by transmitting interference signals. By transmitting a high-power signal of a certain frequency, the surrounding electromagnetic environment is severely damaged, and the mobile phone cannot normally obtain and analyze the signal from the base station, so as to achieve the purpose of shielding the mobile phone signal.
