What should you pay attention to when installing a mobile phone signal jammer? from YIFALIU's blog

The cell phone signal jammer is a new type of information security product that uses specific electromagnetic signals to form a shielding network so that mobile phones cannot receive data from the base station in places that need protection, nor can they connect to the base station. Please note the following four points about signal shielding:

What should I do before installing a cell phone signal jammer?

1. Before installing the equipment, the antenna must be installed correctly according to the signs, and then connected to the power supply to prevent the machine from burning out.

2. Before installing the equipment, you should know the location of the base station and position the shielding cover toward the base station as much as possible.

3. When installing the equipment, pay attention to whether there are metal objects within 1 meter around the machine to prevent signal reflections from affecting the shielding effect.

4. Hearing aids should be installed in special environments such as gas stations and gas stations.

5. The height of the device is 1.8-2 meters. It can be placed directly on the table or wall, or it can be installed on the ceiling. The antenna is perpendicular to the ground, making it easy to use.

6. In indoor equipment, attention should be paid to whether the transmission frequency of wireless equipment will cause co-channel interference.

7. The anti-interference ability and safe distance of existing indoor precision instruments must be considered.

8. If there are signal-enhanced telecommunications machines indoors, it is not advisable to install shielding.

9. Fully understand the boundaries of the shielded area and the unshielded area.

1. Understanding the strength of the on-site signal is crucial for shielding equipment. Various signals have different signal strengths due to their different environments. The on-site signal strength can be designed to be shielded by the equipment.

2. If the device is not detected, you need to know the situation of the base stations around the device address, how far the visual distance is, which base stations (China Mobile, China Unicom, CDMA, 3G, 4G, 5G, etc.) and where the antenna direction of the base station is pointing. Generally, base stations in cities are mostly built on the roofs of high-rise buildings, while towers are often built in suburbs or villages.

3. If you have survey equipment, you only need to record the signal strength at various points indoors and outdoors.
