How to upgrade the jamming 5g of the old mobile jammer?

How to upgrade the jamming 5g of the old mobile jammer?

  • 2022-04-28
After many examinations, such as high school entrance examination, graduate examination, CET-4 and CET-6, various qualification certificates, and the annual civil service examination, candidates who have participated in the examination should be familiar with it. In the examination room, the most common auxiliary equipment in the examination room is the mobile jammer to prevent cheating.
Before 5g was popularized, the jammers used in the examination room could only interfere with 4G. With the continuous development of the communication industry, 5g mobile phones have become popular. So how can the old mobile jammer in the examination room be upgraded to 5g if it can only interfere with 4G? As we all know, the current mobile jammer has basically realized modularization, that is, different frequency bands and different modules are used. Through the rapid replacement of modules, it can realize the advantages of rapid repair or rapid increase of frequency bands. Adding different frequency band modules on the basis of the original 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, which lacks different use scenarios and requires the added functions of jamming modules of different frequency bands. If you want to upgrade to 5g, you must leave a separate module position on the original jammer to add 5g modules. Or add a jammer that only interferes with 5g separately.


The mobile jammer produced by Nanjing Baikang Electromechanical Technology Co., Ltd. has been fully considered in the design. In the later stage, the requirements of adding different frequency band modules can be easily expanded from the original 12 channel output to 24 channel output through the superposition of radiators, and the fixed hole position required for the superposition of radiators is reserved. In this way, even if more frequency bands need to be added in the later stage, there is no need to worry about the insufficient space of radiators. And it can be expanded to 24 interference frequency modules at most to realize more frequency signal interference, or through frequency refinement to achieve the same site and expand the ability of shielding effect.
