Best Materials To Block Cell Phone Signals Prevent Transmission Of Information

Perfectjammer 2022/04/16

In order to better prevent students from using mobile phones to transmit information, leak test papers, and cheat in exams, school exams are also used to prevent tutors from escorting exam papers in the middle of the current exam. Right now, I have entered junior high school in June and this year's college entrance examination. Due to the new crown pneumonia epidemic, the college entrance examination will also be delayed by one month. In order to better ensure the quality of examination cards, many schools have already gradually prepared and established examination venues in advance. Right now, one of the most important things in preparing for the exam room in advance is to install Best Materials To Block Cell Phone Signals . However, it is not possible for anyone to install a mobile phone signal jammer. So, what must be paid attention to in the process of installing the cell phone jammer ? In fact, the installation itself will be very simple, but after some small attitudes in the previous installation determine how the mobile phone signal jammer will work afterwards. For example, the natural environment around the site is also installed at a relative height.

The higher the output power of the mobile phone signal jammer, the better the expected effect, I don't think that is the case. For example, an indoor space design is about 350-600 square meters, and it is necessary to choose to interfere with the mobile phone signal interference of about 700 square meters. Not the more the better. Terminal Best Materials To Block Cell Phone Signals power has a safety factor range for output power. Some consumers have said why when the short video signal is very close, most of the shopkeepers' machines lose the expected effect, while some shopkeepers expect the effect to be very good. The author believes that when the short video signal is close, the data signal has a greater impact on the expected effect. I think the supporting documents are reasonable. Is to follow the safety factor is to derive the power range. On the contrary, when the short video signal is very close, it is very good to interfere with the expected effect, and the export power is not bad. It should be noted that this kind of machine equipment has exceeded all normal use safety factor derived power. It is not that there will be damage to the uplink and downlink short video signals, and there are also potential safety hazards, so consumers who buy should pay attention. Therefore, the output power of the mobile phone signal jammer is not higher and higher.
