Due to the difference in power and number of channels of base stations such as China Mobile, China Unicom, and China Netcom, the distance between the base station and the prison, and the size of other nearby buildings, terrain, and landforms, the signals in the prison area are also different. Because the scale, building structure, local mobile phone base station direction, power, terrain and other factors of each prison are different, the mobile phone signal strength, number of channels and frequency bands in each area of the prison are different. In addition, radio waves are invisible and intangible, and are affected by various factors during their transmission. In the actual use environment, the direction, power, distance of each base station, there may be dozens of channels in the same environment for users to automatically select different characteristics, and there are field strength differences between indoor and outdoor spaces, ground and metal objects. Very complex detrimental effect on the signal of Slot Machine Cell Phone Blocker . So we all have this kind of experience, such as: (a), in different regions, some mobile signals are strong, and some Unicom signals are strong; (b), even in the same place, the signal is also different, there are strong and weak points, so cell phone jammer The system is a highly specialized system project.
Conduct a detailed on-site survey of the prison environment, topography, landforms, etc., very carefully. The survey needs to shield the regional environment, understand the actual requirements of customers, and design personalized solutions. Therefore, it is necessary to carry out project investigation and project solution, and comprehensively solve problems for customers in a scientific and systematic manner. Thorough analysis, thorough analysis of local signal distribution, building structure. Using non-general general equipment positioning, measured by a series of instruments. Choose different composite antennas, and organically combine the application principles of antennas in different frequency bands. After on-site inspection of the building structure, terrain and local base station direction, power, channel, etc.; and has a large number of employees with excellent communication microwave technology, professional business, high quality, strong sense of responsibility, very serious requirements for details, and rich construction experience. , which can meet the construction needs of large-scale system engineering sites, and solve and deal with various difficult problems on site in a timely manner. Complete and rich professional technical data and professional testing and analysis instruments can solve practical problems for clients of the prison and provide them with the best solutions.
