What are the factors that interfere with the effect of the signal jammer in detail? how to deal with from topsignaljammer's blog

1. Due to the different power and number of channels of the signal towers of China Mobile, China Unicom, and China Netcom, as well as the different distances between the signal towers and the prison, and the size of other nearby buildings, terrains, and landforms, the signals in the prison area are also different.

2. Because the scale, building structure, direction, power, terrain and other factors of each prison are different, the signal strength, number of channels, and frequency bands of mobile phones 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 direction, power, and distance of each signal tower in the actual use environment, there may be dozens of channels for the user's mobile phone to automatically select in the same environment. At the same time, there are differences in field strength between indoors and outdoors. And metal objects have very complex adverse effects on the signal shielded by mobile phones. So we all have experiences such as:

(a) In different regions, some mobile signals are strong, while some China 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 highly professional system project.

Approaches taken for the above reasons:

1. Carry out detailed on-site 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 conduct special case investigation and special case resolution, and solve problems for customers in a scientific and systematic manner.

2. Thorough analysis, a thorough analysis of the local signal distribution and building structure. It is positioned by non-general general-purpose equipment and measured by a series of instruments. Choose different composite antennas, according to the organic combination of antenna application principles in different frequency bands.

3. After on-the-spot investigation of the building structure, terrain and local signal tower direction, power, channel, etc.; and has a large number of excellent communication microwave technology, professional business, high quality, strong sense of responsibility, very serious about details, and construction experience Abundant employees can meet the construction needs of large-scale mobile phone signal blocker system engineering sites, and solve and deal with various difficult problems on site in a timely manner. Complete and rich professional technical information, professional testing and analysis instruments, solve practical problems for prison customers, and provide customers with the best solutions.
