The high-power shielding device developed by topsignaljammer Technology Co., Ltd. is specially suitable for prisons, detention centers, labor camps and some large open areas. The high-power jammer adopts advanced shielding technology according to market demand, has government inspection report, and meets national standards.
Through the on-site survey and test data of prisons, detention centers and other special places, the high-power wifi jammer is designed with an aluminum alloy metal shell, which is waterproof, strong, and prevents the deliberate destruction of criminals. The configuration uses a combination of directional antennas and omnidirectional antennas. , so that the mobile phone cannot be called and connected, ensuring the shielding effect and avoiding interference outside the shielding area. A VSWR circuit protection mechanism can prevent the system from being burned out due to short circuit or disconnection of the antenna. It also has great flexibility in antenna configuration and planning interference coverage. High-power jammers can choose to use a variety of alternative antennas and effective segmentation, which only interferes with downlink signals and will not affect the base station. The signal frequency bands included in the device are all independent modules without clutter interference. The interference protection of different frequency bands can be activated or deactivated independently, and the output power level of the ray can be adjusted individually for each frequency band. All in all, the high-power jammer can better shield the signal in the process of use.
If the indoor area of a room reaches 100-300 square meters, at least one of its length and width will exceed 10 meters, or even reach about 20 meters. The current mobile phone jammer, especially the mobile phone jammer with 5G signal shielding, usually has an effective shielding distance radius of 10 meters to 20 meters. In this scenario, if the mobile phone jammer is still installed on a certain If it is in a corner, it is very likely to have such a consequence: the area in the room opposite to the shielding device is very likely to be a place that the distance range of the mobile phone jammer cannot reach. In this area, there will be a blind area that shields the coverage of the signal. How to solve this phenomenon? The solution is simple. The most effective solution is to adjust the installation position of the mobile phone jammer to the middle position appropriately, and use the signal coverage characteristics of the omnidirectional antenna to shorten the distance from the blind area so that the shielding signal can reach the diagonal. area, while maintaining the signal coverage strength of the original location is still sufficient.
