Reasons for different signals due to the influence of external and environmental factors:
1. Due to the difference in power and number of channels of base stations 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.
2. 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.
3. Due to the different characteristics of the actual use environment, the direction, power, distance of each base station, there may be dozens of channels for the user's mobile phone to automatically select in the same environment, and there are differences in the field strength of indoor and outdoor spaces, ground and Metal objects have very complex adverse effects on the signal shielded by the cell 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 also different, there are strong and weak points, so the wifi signal jammer system is a highly professional system project.
Approach to the above reasons:
1. Carry out a detailed on-the-spot investigation of the prison environment, topography, landforms, etc., very carefully. The investigation 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, project solution, and comprehensively solve problems for customers in a scientific and systematic manner.
2. Thorough analysis, thorough analysis of local signal distribution and 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.
3. After on-site inspection of the building structure, terrain and local base station direction, power, channel, etc.; and has a large number of excellent communication microwave technology, professional business, high quality, strong sense of responsibility, very serious requirements for details, and rich construction experience The employees can meet the construction needs of the large-scale mobile phone signal shielding system engineering site, and solve and deal with various difficult problems on site in time. 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.
Look and touch
1. Take a rough look at whether the appearance of the equipment is suitable for special places.
2. Take a closer look at whether the internal structure is scientific and reasonable.
3. Check whether the working temperature of the equipment is normal.
Preliminary effect demonstration
1. The maximum shielding range of the on-site demonstration equipment.
2. On-site demonstration of the controllability of the equipment.
