The shielding effect of signal jammer is not ideal, how to improve the shielding effect?
We often receive more questions from customers, that is, the on-site signal is relatively strong, and the shielding distance of the signal jammer is relatively short. How should we solve this problem? How to improve the shielding effect? This situation has a high probability for manufacturers of signal jammers. There is an operator's base station not far from the use site, or an indoor signal distribution system is installed in the corridor. The on-site mobile phone signal strength is relatively high. As a result, the shielding effect of the signal jammer is greatly affected. In this case, there is no need to panic or complain that the signal jammer produced by the manufacturer has a problem. There are usually ways to improve the shielding effect.
1. When the signal jammer is used on the site, it has a certain shielding effect, but the distance does not meet the requirements. If two identical devices can be configured to solve the problem, two jammers can also be installed, or a spectrum analyzer can be used to detect the signal frequency band on the site, and find the signal frequency that is most difficult to shield through analysis. In the device, add shielding modules for the corresponding frequency band, and then disperse the frequency distribution to adjust the division of the shielding frequency band. High power and narrow bandwidth are used to improve the shielding effect. Reasonably allocate the transmission frequency of each module, which can change the shielding effect on site.
2. The above methods still cannot achieve the expected shielding effect. You can use high-power shielding modules to supplement the targeted shielding of the frequency band with strong frequency signals. Cooperate with low-power signal jammer to achieve full frequency coverage and shielding of mobile phone frequency band. This method can be realized by using the SMa-818K90 high power module of a certain frequency band produced by Nanjing Baikang Electromechanical Technology Co., Ltd. This method can save a lot of costs, and can realize the method with strong shielding effect on site and high cost performance.
