Many people will also think that as the mobile phone signal is upgraded to 5G, then There must be a mobile cell phone jammer that shields the 5G signal. 5G signal jammers are mainly aimed at domestic college entrance examinations, adult college entrance examinations, self-study examinations and various colleges and universities. During the examination process, some criminals use mobile phones to cheat.

Generally divided into low power, medium power, and high power. Except for special occasions, it is generally not recommended to use high-power signal jammers, which will seriously interfere with the base station signal transmission and also have a certain degree of radiation to the human body. For educational exams, it is recommended to use low-power in standardized examination rooms and conference rooms. Even if a low-power one cannot achieve the effect in some places, you can choose multiple cellular layouts. This effect is better than the effect of using a single medium or high power, and the radiation is not that big.
