Three steps to install a wifi jammer

Admin Posted on 2022-10-19

The wifi jammer is a new type of information security product. It uses a specific electromagnetic signal to form a shielding network in the place that needs to be protected so that the mobile phone cannot receive data from the base station and cannot establish contact with the base station. There are four important things you need to know about wifi signal jammers:

Before wifi jammer equipment installation

1. Before installing this wifi jammer device, be sure to install the antenna correctly according to the signs, and then turn on the power to prevent the machine from being burned out.

2. Before installing the equipment, you should understand the orientation of the base station, and try to make the direction of the wifi blocker follow the direction of the base station.

3. When installing wifi blocking device, you should pay attention to whether there are metal objects within 1 meter of the machine to prevent the formation of signal reflection, which will affect the shielding effect.

4. In special environments such as gas stations, gas stations, etc., explosion-proof machines should be installed.

5. The height of the device is preferably 1.8-2 meters. It can be placed directly on the table, on the wall, or on the ceiling. It is better that the antenna and the ground are straight.

6. If it is installed indoors, you should pay attention to whether the transmission frequency of the existing wireless equipment in the room causes co-channel interference.

7. The tolerance and safety interval of anti-interference interference of existing indoor fine instruments must be considered.

8. If an amplifier such as signal enhancement is installed in the room, it is not suitable to install a shield.

9. Fully understand the boundary between the shielded area and the non-shielded area.

2. On-site investigation

1. Knowing the signal strength of the field is very important for the installation of the wifi signal blocker. Because there are many kinds of signals in an environment, and the strength of each kind of signal is different, so knowing the signal strength of the scene can be targeted to designing the wireless wifi jammer.

2. In the absence of survey equipment, it is necessary to know the status of the surrounding base stations of the device address, how far is the visual distance, what base station (mobile, China Unicom, CDMA, 3G, 4G, 5G, and other base stations), and the direction of the antenna of the base station is Which way to point. In general, base stations in cities are mostly built on the tops of taller buildings, and in suburbs or villages, they are mostly iron towers.

3. If there is survey equipment, it is only necessary to record the signal strength of multiple indoor and outdoor points on site in detail.

3. Equipment installation

1. According to the results of the survey, reasonable matching of different signals has reached the ideal situation, and the degree of interference in the unshielded area and the impact on the surrounding base stations should be fully considered.

2. Confirm the schematic diagram of the installation. In the actual installation process, first install the place with strong signal (that is, the place closest to the base station), select the directional antenna, and start the installation in the direction of the base station antenna.

3. Consider the floor height of the shielding area. Since the signal on the upper floor is better than that on the lower floor, the order of installation from top to bottom is selected to achieve the best shielding effect.

4. Fully consider the anti-interference of the PHS base station. The power of the PHS base station is generally relatively small, and the PHS has no uplink and downlink lines.
