The wifi jammer is a new type of network information security product. It uses a specific electromagnetic induction signal to generate a mobile phone shielding base station network in the site that needs to be protected, so that the transfer mobile phone cannot receive signal data information, and cannot get in touch with the signal tower. So what are the rules for installing a wifi blocker?
Before installing the wifi blocker device
1. Before installing the wifi jammer machine, be sure to install the wireless antenna properly according to the label, and then turn on the switching power to avoid the installation being burned;
2. Before installing the equipment, you must first grasp the direction of the signal, and try to make the orientation of the wifi signal blocker along the orientation of the signal;
3. When installing machinery and equipment, pay attention to whether there are metal objects about 1 meter around the installation, so as to avoid the generation of signal reflection surfaces and even damage the shielding effect;
4. Especially in special environments such as gas stations. Gas stations should be installed with explosion-proof installation;
5. The relative height of the installation is 1.8-2 meters. It can be placed on the table at the same time and can be installed on the wall or on the ceiling. It is better for the wireless antenna and the road to be straight;
6. When installing in the room, pay attention to whether the transmission frequency of the wireless network equipment already stored in the room will cause harm to the same screen;
7. Be sure to consider the tolerance and safety distance of the current meticulous instruments in the room against abnormal frequency hazards;
8. If the room is equipped with an amplifier such as a signal booster, it is not appropriate to install a wifi frequency jammer;
9. Fully grasp the boundaries between shielded areas and non-shielded areas.
2. On-site survey
1. Mastering the compressive strength of the signal on the spot is very important for the configuration of the shield. Since there are various signals in a special environment, and the compressive strength of various signals is different, it is necessary to master the signal resistance on the spot. The compressive strength can be purposefully designed, manufactured, and installed to install the wifi signal blocker;
2. In the absence of survey equipment, it is required to grasp the situation of the signal near the installation address, estimate the distance, what kind of signal (transfer, China Unicom, CDMA, 3G, 4G, 5G, etc.), wireless signal Where is the orientation of the antenna? Generally, the signals in big cities are mostly located on the roofs of higher houses, and towers are often seen in suburban or rural areas;
3. If there is survey equipment, it is only necessary to completely record the signal compressive strength of several points outdoors in the room on the spot.
Install the wifi jammer equipment
1. According to the results of the survey, to carry out effective matching of different signals, the most ideal situation has been achieved, and the hazard level of the unshielded area and the hazard to nearby signals should be fully considered;
2. Determine the approximate installation plan. During the whole process of practical installation, mainly install the local area with a strong signal (that is, the local area closest to the signal), use a directional antenna, and start the installation along the direction of the signal wireless antenna;
3. Considering the floor height of the shielded area, since the high-rise residential signal is better than the bottom floor, the installation sequence from top to bottom is adopted to achieve the best shielding effect;
4. Considering the damage resistance of PHS signals, the output power of PHS signals is generally relatively small, and PHS has no uplink and downlink routes. Signals are very easy to digest and absorb hazardous signals, and the generated signals cannot be normal Work.
