In some special geographical environments, if the mobile phone signal is strong in the field environment where frequency jammers are used, most of the reasons are that there are signal towers nearby which are close to each other. However, if mobile phone signal amplifiers are installed in the building, the signal will become very good. According to the working principle of these jammers, the field environment and the influence of nearby base stations, some measures can be taken to reasonably arrange them, so as to reduce the factors that affect the shielding range of the jammers in normal use, and improve the interference effect of their frequency jammers.

Multiple jamming devices can be used together to achieve full coverage of site signals. If you are indoors, you can turn off the signal amplifier and contact the relevant operators to reduce the power output of nearby base stations, so as to reduce the strength of mobile phone signals around the site and ensure the interference effect of frequency jammers. Professional equipment can be used to test the frequency parameters on site to know the strength of the actual signal. According to the actual situation, the use of high-power jammer has reached the ideal effect of frequency jammer. Whether by increasing the number of interference devices, reducing the power of the on-site environmental signal, or using high-power machinery and equipment, different methods should be selected according to the actual situation on site to ensure that the effect of the interference meter can be fully utilized.
