How to make the signal of the mobile phone signal jammer stronger

The mobile phone signal jammer is to shield the mobile phone from receiving the signal of the base station, it will attenuate when encountering obstacles. If it is a reinforced concrete solid wall, the attenuation after penetration is very large; if it is made of gypsum board, the attenuation should be smaller; if it is made of glass or wood, there is basically not much attenuation. Today, Texin Electronics tells you how to install the mobile phone The signal jammer signal becomes stronger.

 

The first step: Take a used can, clean it, and pull out the ring

 

Step 2: Perform ring cutting on the bottom of the tank as shown in the figure to remove the entire bottom

 

The cut bottom is unnecessary

 

The third step: As shown in the picture, cut the top of the tank in a ring. Be careful not to cut it completely. Leave the 1-2 cm part without cutting and the 1-2 cm part must be close to the mouth of the tank.

 

Step 4: Draw a red line vertically on the reverse side as shown in the picture and cut off the iron sheet along the middle of the red line

 

Step 5: Slowly spread out the cut iron sheet into a fan shape

 

Step 6: Put the finished fan-shaped iron shell on the antenna of the Texin mobile phone signal jammer, as shown in the figure, if there are many antennas, we can make 2-3 of the same iron shell.

 

Due to the limited material, we only made one iron sheet. It would be better to make 2-3 pieces. After doing this, install and fix the mobile phone signal jammer on the wall, so that the emission effect is doubled and the penetration effect is stronger.

 

 

What are the factors of the effect of the signal jammer

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 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’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 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, 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 instruments, solve practical problems for prison customers, and provide customers with the best solutions
