Since the 4G signal was launched in 2014, 7 years have passed. The times are advancing, the communication technology is developing, and the commercialization of 5G is getting closer and closer. 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. At the same time, it also combines various intermediate and senior middle school students using mobile phones to chaotically during class hours. The status quo of texting. And the troubles and noises caused by mobile phones in serious places such as various large, medium and small meeting rooms of government agencies and enterprises, concert halls, theaters, etc. High-tech products carefully developed according to the actual situation of domestic mobile communication.
The mobile phone signal jammer only needs to ensure that the communication signal is shielded in a certain small area, so it is easier to interfere as long as the frequency band can be covered. More challenges of mobile jammers. Don’t think that if the mobile phone signal is blocked, everything will be fine! I heard that someone once used the “WIFI name” to complete the transmission of the answer. It seems that the development of mobile phone signal jammers should not be relaxed for a moment, and see if we need to upgrade to the 5GHz frequency band! According to reports, there are also illegal self-made radio transceiver equipment that maliciously use frequency bands that are not covered by mobile phone jammers.
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.
