How to solve the problem that the shielding effect of mobile jammers cannot meet the requirements of shielding places?
Friends who are familiar with mobile jammers should have encountered situations where there is an operator's base station nearby or an indoor signal distribution system installed in the hallway. The shielding effect of mobile jammers has been greatly affected. How to deal with such a scene or how to configure mobile jammers reasonably.
1. If the prepared mobile jammer is on site and has a certain shielding effect, but the distance does not meet the requirements, if two identical mobile jammers are configured to solve the problem, two can be configured, or a spectrograph can be used to detect the signal spectrum on site. Through analysis, the most difficult signal frequency to shield can be identified. Then, in the mobile jammer, a shielding module for the corresponding frequency band can be added, and the frequency distribution can be dispersed, Reasonably allocating the transmission frequency of each module can improve the shielding effect on site to a certain extent.
2. If the first method still fails to achieve the expected shielding effect, a high-power shielding module can be used to supplement targeted shielding for a strong frequency band of a certain frequency signal. Cooperate with low-power mobile jammers to achieve full frequency coverage and shielding of mobile phone frequency bands. Through this method, the SMa-818K90 module or the high-power module SMa-818K200 produced by Nanjing Baikang Electromechanical Technology Co., Ltd. can be used to achieve the above method. This method can significantly save costs and achieve on-site signal shielding. The cost-effectiveness is very high.
