I, Nanjing Bokang Electromechanical Technology Co., Ltd. can give a quick solution to upgrade to 5G jammers: customers can continue to use the original old signal jammers to keep the original performance of shielding mobile phone signals. In the 5G signal frequency band, 2-3 SMa-818K90 medium-power 5G jammer modules newly developed and produced by our company can be added directly. This 5G blocker module can be freely spliced and combined, independently powered and used, and can block the frequency band only for 5G in the mobile phone signal.

It should be noted that the 5G jammer module added in this way has a single module transmit power of 10-20W, which is greater than the transmit power of the old signal jammer (2-3W). Therefore, customers can Correspondingly, the number of points of the newly added 5G shield is reduced, which is also beneficial to customers to save costs and quickly solve the problem of 5G shielding mobile phone signals.
1. For the actual combat scene of bomb disposal and EOD, the electronic shielding device using the detection frequency sweep method first scans the suspicious frequency points and then starts the interference signal to suppress. There is a time difference. Once the suppression of the remote control signal is not immediate, the consequences are extremely serious. 2. Also for the EOD site, the current remote control technology can achieve wide-band frequency hopping or multi-frequency remote control. Once there is a multi-frequency and frequency-hopping wireless frequency band, the electronic shielding device that detects the frequency sweeping method is scanning. The bandwidth of the interference signal output after the frequency will be widened, and the shielding or interference suppression distance will be greatly reduced. 3. For the application of anti-terrorism scenarios, if terrorists use mobile phone communication during communication, or use mobile phone to detonate remotely, etc., the scanning method of electronic shielding device with detection frequency scanning method cannot achieve all identification and discovery for mobile phones. Even if all the shielding modules are manually turned on, its bandwidth will be stretched too wide, and the shielding distance will be close to 0. Everyone understands: the current mobile phone frequency is from 700MH-4900MH, and there will be 6G in the future... New 4 Antennas Portable Mini GSM/GPS Jammer 4. Some people propose to adopt the electronic signal jammer of the detection frequency sweep method. The total number of broadband power amplifiers and power amplifiers used is small. When interference is required, only the corresponding frequency band needs to be selected for power amplifier output. In this way, the electronic shielding The power consumption of the device is less. However, in actual combat applications, the power consumption of the power supply is not worth mentioning compared to preventing a terrorist incident. The prevention of terrorism is of course the most important thing to ensure the safety of life!
Signal JammerWhen the mobile phone shielding device tests the shielding effect of the use site, it is often encountered that the shielding effect of the mobile phone shielding device on the mobile phones of different operators is different, and some are even very different. This situation is often encountered in the process of testing or use, so what is the reason for such a situation, and how to deal with such a situation?
The reason why this happens in the first place is because the signal strength of mobile phone signals of different frequencies transmitted through the base station to the site of use is different, and the signal strength of the white noise interference signal of the same frequency of the mobile phone signal transmitted by the mobile phone jammer is not the same. changing. So let the white noise interference signal with the same signal strength emitted by the mobile phone shielding device to shield the mobile phone signal of different frequencies to the mobile phone signal with different signal strength at the use site, and the shielding distance of the mobile phone of different operators is different. Using the shielding scheme of white noise interference mode, the shielding effect depends on the strength of the mobile phone signal at the site. It can also be understood as the distance of the surrounding operator base stations. The stronger the signal at the scene, the closer the shielding distance of the mobile phone GPS jammer, and vice versa. The mobile phone signal is too strong, so that the mobile phone is placed next to the mobile phone shielding device, and the mobile phone can still be used normally without any influence. This situation is also relatively common. In this case, conventional cell phone jammers cannot be used.
