How to add other signal frequency bands to the mobile phone signal jammer used in the examination room?

We have to go through a lot of examinations, including high school entrance examination, college entrance examination, postgraduate entrance examination, etc., CET 4 and 6, various qualification certificate examinations, the annual civil service examination and so on. In the exam room, the rarest test room aids are cell phone jammers to avoid cheating.

The current mobile phone signal jammer has basically completed the modularization, that is, different frequency bands, using different modules, through the rapid replacement of modules, can achieve rapid repair or rapid addition of frequency bands and other advantages. Adding modules of different frequency bands 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 designed according to the standard frequency bands of mobile phones, lacking different application scenarios, and need to add different frequency bands The interference module function.

The mobile phone signal jammers produced by Nanjing Bokang Electromechanical Technology Co., Ltd. have been fully considered in the design. The fixed holes for the superimposed radiator plate are reserved, so that even if more frequency band mobile phone signal jammers need to be added in the early stage, there is no need to worry about the lack of radiator space. And it can be extended to up to 24 interference frequency modules to complete more frequency signal interference, or to achieve the opposite scene through frequency refinement, to expand the ability of shielding effect.
