Block Cell Phone Tracking Apple Drops Signal

The Block Cell Phone Tracking Apple used in the test room is a full frequency band, which can block all 2G 3G 4G mobile phone signals and 2.4G WIFI signals of China Mobile, China Unicom, and China Telecom. So as long as there are cell phone jammer in the classroom, all cell phones cannot make or receive calls. Texting and surfing the Internet. It is absolutely wrong to say that signal jammers do not block China Telecom and China Unicom. Unless there are telecommunications and China Unicom signal towers near the location of use, the signals of China Telecom and China Unicom's mobile phones are particularly strong, and the power of mobile phone jammers is too small to suppress. At this time, there may be situations where China Telecom and China Unicom cannot be shielded. Also, it is wrong to have a cell phone against a wall with a signal, but the farther away you are from cell phone jammers, especially the windows may leak the signal.

Some high-power mobile phone jammers will emit a lot of heat when they are working, and these need to be dissipated, but many friends do not know much about the heat dissipation principle of mobile phone jammers. Today, the mobile phone signal jammer manufacturer will introduce to you how Block Cell Phone Tracking Apple is dissipating heat. Follow the editor to learn about it. Among the commonly used metal materials, silver has the best thermal conductivity, followed by copper and aluminum. However, silver is expensive and is rarely used for heat dissipation. Copper has good thermal conductivity but doesn't dissipate very quickly. This may cause the cell phone signal to be blocked for 24 hours, the heat of the machine cannot be dissipated, and it becomes invisible in a small space. heat source. In the case of high temperature in summer, the danger can be imagined. In contrast, aluminum is the most ideal,
