1. Due to the different power and channel numbers of the signal tower and the different distances between the signal tower and the prison, the size of other nearby buildings, terrain, and landforms are different, resulting in different signals in the prison area.
2. Because the scale, building structure, local cell phone tower direction, power, terrain and other factors are different for each prison, the cell phone signal strength, number of channels, and frequency bands are different in each area of the prison. 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 to automatically select the mobile phone. At the same time, there are differences in the field strength of the space between indoor and outdoor, and the ground And metal objects have a very complicated adverse effect on the signal shielded by the cell phone scrambler. 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 if the signal is different in the same place, there are strong and weak points, so the mobile phone signal shielding system is a highly professional system project.
Measures taken for the above reasons:
1. Conduct detailed field surveys, topography, and landforms 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, topography 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 large-scale mobile phone signal shielding system projects, 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.
