What factors affect the stability of Jammer Devices?

Reasons for different signals caused by the influence of external and environmental factors:

  1. Due to the different power and channel numbers of base stations such as China Mobile, China Unicom, and China Netcom, and the distance between the base station and the prison, the size of other nearby buildings, terrain, and landforms are different, resulting in different signals in the prison area.
  1. Because the scale, building structure, local mobile phone base station 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.
  2. Due to the different characteristics of the actual use environment, the direction, power, distance, and distance of each base station, 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 indoor and outdoor spaces, the ground Metal objects cause very complex adverse effects on the signal shielded by the mobile phone. So we all have this experience. For example: (a) In different areas, some mobile signals are strong, while some Unicom signals are strong; (b) Even in the same place, the signal is different, there are strong and weak points, so mobile phones The signal shielding system is a highly professional system project.

Measures taken for the above reasons:

  1. Carry out 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, terrain and local base station direction, power, channel, etc.; and has a large number of strong communication microwave technology, sophisticated 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 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.

Trust and distrust

  1. Trust large-scale classic engineering cases that can be investigated.
  2. Trust the test report provided by the authority in the actual engineering case.
  3. Don’t believe the maximum shielding range provided in the product manual.
  4. Don’t believe in a large number of unverifiable engineering cases.

See and touch

  1. 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 demonstration

  1. The maximum shielding range of the live demonstration equipment.
  2. On-site demonstration equipment can be controlled.
