What are the reasons for interfering with the effect of signal jammers?
1. Due to the different power and number of channels of signal towers such as China Mobile, China Unicom, and China Telecom, as well as the different distances between the signal towers and the prison, and the different sizes of other nearby buildings and topography, the signals in the prison area are also different.
2. The scale, building structure, local mobile phone signal tower direction, power, terrain and other factors of each prison are different, which results in different cell phone signal strengths, channel numbers, and frequency bands in various areas of the prison. In addition, radio waves are invisible and intangible, and their transmission is affected by various factors.
3. Due to the different characteristics of the actual use environment, the direction, power, and distance of each signal tower, there may be dozens of channels for users to automatically select in the same environment. At the same time, there are differences in spatial field strength indoors and outdoors, and ground and metal objects cause very complex adverse effects on the signals blocked by mobile phones. So we all have this experience, such as:
(a) In different areas, some mobile signals are strong and some China Unicom signals are strong;
(b) Even in the same place, the signals are different, strong and weak, so the mobile phone signal blocking system is a highly professional system project.
Measures taken for the above reasons:
1. 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 the customer, and design personalized solutions. Therefore, it is necessary to carry out special project investigation and solution, and comprehensively solve problems for customers in a scientific and systematic manner.
2. Thoroughly analyze the local signal distribution and building structure. It is positioned using non-general equipment and measured by a series of instruments. Choose different composite antennas based on the organic combination of antenna application principles in different frequency bands.
3. After on-site investigation of the building structure, terrain and local signal tower direction, power, channel, etc.; and have a large number of people with excellent communication microwave technology, professional skills, high quality, strong sense of responsibility, very serious requirements for details, and construction experience The rich staff can meet the construction needs of large-scale cell phone signal jammer engineering sites and solve and handle various difficult problems on site in a timely manner. Complete and rich professional technical information and professional testing and analysis instruments can solve practical problems for prison customers and provide customers with the best solutions.
