Introduce in detail what are the factors that interfere with the effect of the prison signal jammer? How to deal with it
1. Due to the different power and number of channels of the signal towers of China Mobile, China Unicom, and China Netcom, and the different distances between the signal towers and the prison, the size of other nearby buildings, terrain, and landforms are different, resulting in different signals in the prison area.
2. Because each prison has different factors such as the scale, building structure, the direction of the local cell phone tower, power, and terrain, the cell phone signal strength, channel number, 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. 3. Due to the different characteristics of the actual use environment, the direction, power size, distance and distance of each signal tower, there may be dozens of channels in the same environment for the user's mobile phone to automatically select different characteristics, at the same time there is a difference in the field strength of the space between indoor and outdoor, and the ground And metal objects cause very complex adverse effects on the signal shielded by the mobile phone. So we all have this 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 different, there are strong and weak points, so the mobile phone signal shielding system is a very professional system project. Measures taken for the above reasons:
1. Conduct detailed field surveys, topography, landforms, etc. of the prison environment, very carefully, the survey needs to shield the area environment, understand the actual requirements of customers, and design personalized solutions. Therefore, it is necessary to carry out project investigation and project solution, and solve the problems for customers in a scientific and systematic way.
2. Thorough analysis, thorough analysis of local signal distribution and building structure. Using non-general general equipment for positioning, measured by a series of instruments. Choose different composite antennas and organically combine the principles of antenna application in different frequency bands.
3. After on-site survey of the building structure, terrain and local signal tower direction, power, channel, etc.; and have a large number of communication microwave technology, sophisticated business, high quality, strong sense of responsibility, very serious requirements for details, and construction experience Abundant employees can meet the construction needs of the large-scale mobile phone signal shielding system project, and solve and deal with various difficult problems on the spot in time. Complete and abundant professional technical information, professional test and analysis equipment, solve practical problems for prison customers, and provide customers with the best solutions.
