How to add other signal frequency bands to the cell phone signal jammer used in the examination room from dojammer's blog

We have to go through many examinations, including the junior high school entrance examination, the college entrance examination, the postgraduate examination, the CET-4 and CET-6 examinations, various qualification certificate examinations, and the annual civil service examination, etc. In the examination room, the most common examination auxiliary equipment is the cell phone signal jammer to prevent cheating.

Nowadays, the cell phone signal jammer has basically achieved modularization, that is, different frequency bands use different modules. Through the rapid replacement of modules, it can achieve the advantages of rapid repair or rapid increase of frequency bands. Adding different frequency band modules on the basis of the original cell phone signal jammer is still a headache for many manufacturers, because at the beginning of the design, they were designed according to the standard mobile phone frequency band, lacking different usage scenarios and the functions added by the interference modules of different frequency bands.

12 Bands Signal Jammer

The cell phone signal jammer produced by Nanjing Bokang Electromechanical Technology Co., Ltd. has been fully considered in the design. The requirements of adding modules of different frequency bands in the later stage can be easily realized by superimposing the radiator, which can easily expand the original 12-channel output to 24-channel output. The fixed holes required for superimposing the radiator are reserved, so that even if more frequency bands of cell phone signal jammers need to be added in the later stage, there is no need to worry about insufficient space for the radiator. And it can be expanded to up to 24 interference frequency modules to achieve signal interference of more frequencies, or to achieve the same scene through the refinement of the frequency, and to expand the ability of shielding effect.
