How to increase the intercom frequency band of the cell phone signal jammer used in the examination room from dojammer's blog

As the most common auxiliary equipment in the examination room, the cell phone signal jammer is a magic weapon to prevent candidates from cheating. According to the different wireless signal interference frequency bands configured inside the jammer, the functions of different wireless signal interference are also different, so how to increase the interference of the wireless intercom frequency band.

Nowadays, cell phone signal jammers have basically realized modularization, that is, different interference modules are used according to different wireless signal interference requirements on site and different frequency bands. Through the rapid replacement of modules, the advantages of rapid repair or rapid increase of wireless signal interference frequency bands can be easily achieved. However, 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 of the cell phone signal jammer, it was designed according to the standard mobile phone frequency band, and there was no space for increasing the frequency band. If the original jammer cannot add interference modules under different usage requirements, then more wireless signal interference requirements cannot be achieved.

The cell phone signal jammers produced by our company have fully taken this into consideration when designing. If there is a requirement to add modules with different frequency bands on site, the radiator can be superimposed to easily achieve the original 12 interference frequency band outputs and expand more wireless interference channel outputs. The fixed holes required for superimposing radiators are reserved, so that even if more frequency bands of cell phone signal jammers need to be added later, there is no need to worry about insufficient radiator space. It can be expanded to up to 24 interference frequency modules to achieve signal interference of more frequencies, or to achieve the same site through frequency refinement to expand the ability of interference effect.
