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 designed according to the standard mobile phone frequency band, lacking different usage scenarios, requiring the increase of interference modules in different frequency bands function.
