What is an interference blind spot?
An interference blind spot refers to the inability of phone signal jammers to effectively interfere with mobile phone signals in certain areas, resulting in the mobile phone signals in these areas being unobstructed. This situation may be caused by a variety of reasons, such as environmental obstacles, insufficient jammer power, improper antenna position, etc.
Methods for troubleshooting and solving interference blind spots
1. Check environmental factors
1.1 Influence of obstacles
Solution:
Check for obstacles: Check whether there are large obstacles around the cell phone jammer, such as walls, metal furniture, large appliances, etc. These obstacles may block the propagation of interference signals, resulting in the appearance of interference blind spots.
Adjust the jammer position: Try to move the jammer to a more open position to avoid being blocked by obstacles. Choose to place it in a higher place, such as the top of the room, to reduce the possibility of the signal being blocked by obstacles.
Increase the number of jammers: In a complex environment with many obstacles, consider increasing the number of jammers and placing them in different locations to cover all areas.
1.2 Reflection and refraction
Solution:
Adjust the antenna angle: By adjusting the angle of the jammer antenna, you can optimize the reflection and refraction path of the signal to ensure that the signal can effectively cover all areas.
Use directional antennas: In some cases, using directional antennas can focus the signal transmission to a specific direction and reduce the reflection and refraction loss of the signal.
2. Adjust the jammer settings
2.1 Increase the transmit power
Solution:
Check the power setting: Make sure the power setting of the jammer is within the appropriate range and increase the transmit power as needed.
Test signal strength: Use a signal strength tester to measure the interference signal strength in each area, and adjust the transmit power according to the test results to ensure that all areas can be effectively covered.
2.2 Frequency setting optimization
Solution:
Check frequency coverage: Make sure that the frequency setting of the jammer covers all target frequency bands, including 2G, 3G, 4G and 5G.
Adjust frequency settings: According to the actual situation, optimize the frequency setting to ensure that all frequency bands that need to be interfered are covered. Use a spectrum analyzer to check the signal frequency bands in the surrounding environment to ensure that there are no omissions.
3. Antenna optimization
3.1 Antenna position and layout
Solution:
Optimize antenna position: Make sure the antenna is located in the center or reasonable position of the target area to avoid being blocked by obstacles.
Adjust antenna height: Adjust the antenna height as needed to ensure that the signal can effectively cover all areas.
Arrange antennas in different areas: In large areas or complex environments, you can use the method of arranging antennas in different areas to ensure that each area can be effectively covered.
3.2 Multi-antenna system
Solution:
Use multi-antenna system: In large areas or complex environments, use multi-antenna system to achieve more comprehensive coverage through the cooperation of multiple antennas.
Optimize antenna direction and angle: Adjust the direction and angle of the antenna according to the specific situation of each area to ensure that each antenna can cover the target area to the maximum extent.
4. Use signal amplifier
Solution:
Use of signal amplifier: In some cases, you can use a signal amplifier to enhance the coverage of the interference signal. The signal amplifier can amplify the signal emitted by the jammer so that it can cover a wider area.
Test the amplification effect: Use a signal strength tester to test the coverage of the amplified signal to ensure that the amplifier can effectively cover all areas.
5. Regularly maintain and update the device
Solution:
Regularly check the device: Regularly check the power supply, antenna and internal components of the jammer to ensure that they are working properly.
Update the device software: If the jammer supports software updates, update the device software in a timely manner to ensure that it has the latest functions and optimizations.
Clean the device: Regularly clean the heat dissipation holes and fans of the jammer to ensure that the device is well cooled and prevent overheating from affecting performance.
During the use of the phone signal jammer, there may be interference blind spots. This problem can be effectively solved by checking and eliminating environmental factors, adjusting the jammer settings, optimizing the antenna position and layout, using signal amplifiers, and regularly maintaining and updating the device.
