How to design, install and debug the jammer system?

Design, installation and commissioning of jammer system:

1.Common problems before installation:

Make sure the antenna is installed correctly according to the instructions before powering on to avoid damage.
Determine the direction of the communication base station before installation and place the jammer accordingly.
Pay attention to whether there are metal objects within about 1 meter around the device to avoid signal reflection and interference.
When installing the device outdoors, please take moisture-proof and lightning protection measures.
In special environments such as gas stations, please install explosion-proof equipment.
The recommended installation height is 1.8-2 meters. The jammer can be placed on a table, wall or ceiling, and the antenna is best placed vertically.
Check whether there is potential same-screen interference with existing wireless network equipment in the room during installation.
Consider the withstand voltage and spacing of sensitive instruments in the room to mitigate the impact of different frequencies.
Avoid installing jammers in rooms with signal receivers or amplifiers.
Clearly understand the boundaries between shielded and unshielded areas.

2.On-site inspection:

Understanding the sensitivity of signal reception is essential for designing and using jammers. In the absence of specialized survey equipment, collect information about nearby base stations, estimate their distances, identify network providers (China Mobile, China Unicom, CDMA, 3G, etc.), and determine the direction of their antennas. In urban areas, base stations are often located on the roofs of high-rise buildings, while towers are more common in suburbs or villages. If survey equipment is available, record the receiving sensitivity of each point indoors and outdoors. Best-selling WIFI jammers and GPS jammers in Europe and America.

3.Design an installation plan:

Based on the survey results, design an effective configuration that optimizes signal suppression while considering the impact on nearby base stations and unshielded areas.

3.1 Clarify the overall assembly plan. Start installation from the area with strong signals, closest to the communication base station. Use directional antennas and gradually align them with the angle of the mobile communication base station.

3.2 Consider the height of the shielded area. In high-rise buildings, the signal is strong on the lower floors. The top-down installation sequence should be adopted for the best shielding effect.

3.3 Consider the anti-interference ability of the PHS communication base station. Since the output power of the PHS base station is relatively low, the uplink and downlink lines are limited, and it is susceptible to electromagnetic interference, the system should be carefully designed to ensure the normal operation of the PHS communication base station.
