How can the cell phone signal jammer used in the examination room increase other signal frequency bands?
We have to go through many exams, including high school entrance exams, college entrance exams, postgraduate exams, etc., CET-4 and CET-6 exams, various qualification certificate exams, and the annual civil service exam, etc. In the exam room, the most common exam room auxiliary equipment is to prevent cheating Cell phone jammers.
The current mobile phone signal jammer has basically achieved modularization, that is, different frequency bands, using different modules, through the rapid replacement of modules, can achieve rapid repair or rapid increase in frequency bands and other advantages. Adding different frequency band modules on the basis of the original mobile phone signal jammer is still a headache for many manufacturers, because at the beginning of the design, they are all designed according to the standard mobile phone frequency band, lacking different usage scenarios, and needing to increase the interference modules of different frequency bands function.
The mobile phone signal jammer produced by Nanjing Bokang Electromechanical Technology Co., Ltd. has been fully considered in the design. The requirements of different frequency bands are added later. Through the superposition of the radiator, the output of the original 12 channels can be easily extended to The 24-channel output has reserved fixed holes for superimposing the radiator, so that even if more frequency bands for mobile phone signal jammers need to be added later, there is no need to worry about the lack of space for the radiator. And it can be extended to 24 interference frequency modules at most to achieve more frequency signal interference, or to achieve the same scene through frequency refinement to expand the ability of shielding effect.
