Cell phone signal jammers can be used for mobile phones of different operators, but the effects of blocking mobile phone signals vary. The base stations of the three major operators, China Mobile, China Unicom, and China Telecom, publish different signal strengths in different frequency bands, different number of channels, different distances between base stations and sites, whether there are obstructions between base stations and sites, and the size of other surrounding buildings and landforms, which leads to different signals in this area. Due to the differences in building structure and local base station location, output power, landforms and other factors, the mobile phone signal strength, number of channels, and frequency bands in different regions are different.
Generally, mobile phone signal jammers are used within a specific range. In the same environment, there will be dozens of channels for customers to automatically choose mobile phones. At the same time, the difference in the intensity of the magnetic field indoors and outdoors, the road surface and metal will have a greater adverse effect on the signal of the mobile phone signal jammer. At this time, everyone will feel that in various regions, sometimes the mobile signal is strong, sometimes the China Unicom signal is strong, and the signal strength of different operators in various locations is also different. At this time, the mobile phone signal jammer reflects the difference in the effectiveness of the mobile phone signal jammer in shielding the signals of different operators in different application environments.
Now we can conduct detailed field surveys of the environment, survey the various signal frequency and signal magnetic field strength environments in the areas that need to be shielded, and explore the specific requirements of customers. We can conduct a comprehensive analysis of the surrounding buildings and structures where different frequency bands of mobile phone signals are distributed and need to be shielded. We use general mechanical positioning, and measure through a series of instruments to improve the working frequency of mobile phone signal blockers. We can promptly handle and solve various common problems on site, solve problems for customers, and provide the best solutions.
