How to improve the interference effect of frequency jammer when the on-site signal is too strong?
The strong mobile phone signal on the site is generally due to the close proximity of the surrounding base stations and the installation of an indoor mobile phone signal distribution system in or around the building, referred to as a mobile phone signal amplifier. According to the working principle of the frequency jammer, the base stations around the conference room and the indoor signal distribution system are the main factors affecting the shielding range of the frequency jammer. In this case, if you want to improve the shielding effect of the shield, you can start from the following aspects:
1. Increase the number of frequency jammers, and use multiple jammers to cover the entire conference room.
2. Get the strongest frequency band of the on-site mobile phone signal through the spectrometer test or mobile phone signal detection software Cellular Z, and make a high-power shielding module for this band according to the tested frequency parameters to specifically shield the strong frequency band of the mobile phone signal, so as to achieve the effect that the frequency jammer shields these signals.
3. You can contact the operator of the base station or the indoor mobile phone signal distribution system to reduce the on-site mobile phone signal strength by adjusting the transmission power of the base station or adjusting the direction of the antenna board, so as to ensure the shielding effect of the frequency jammer.
The high-power machine SMa-818K90 produced by Nanjing Baikang Electromechanical Technology Co., Ltd. Customized (100MHz - 6000MHz) can be selected at will. The module group can be disassembled and spliced at any time to facilitate future frequency band upgrade and spread spectrum;
It can be used together with low-power frequency jammers. In case of strong frequency bands of individual signals, targeted modules can be selected to enhance the suppression effect;
The transmission power of each channel is 10-20W, and the modules (frequency bands) can be freely spliced and combined;
6-8 modules are recommended for each splicing combination, and each switching power supply can supply power to 2 module groups at the same time;
Omnidirectional antenna (7dbi) can be selected, or a converted backplane directional antenna (12dbi) can be installed;
