In some special areas and periods in our lives, we may use a device like a wifi jammer, but do you know the composition and placement of a wifi signal jammer?
Parts of a wifi signal jammer
The components of the wifi jammer generally include the host, the antenna, and the power adapter. When installing the wifi signal jammer, because there is a strong signal magnetic field within a certain distance between the host and the antenna (usually 20-30 cm), and there is also magnetic field disturbance around the 220V power line (strong electricity) (usually 5-10 cm), Therefore, how to place the device orientation of each component is very critical. If the placement orientation is incorrect, it is likely that the transmission of the shielded signal will be disturbed and the shielding effect will be affected.
The standard device spacing of each component of the wifi jammer is as follows:
The power adapter should be more than 20cm away from the host; (if the wifi signal blocker is installed, it is limited by the site installation environment, and the power supply cannot be kept away. You can place the power adapter under the host of the wifi blocker, and choose this method. After that, the power adapter will still be disturbed by the strong magnetic field from the host of the wifi frequency jammer, but it will be less disturbed than placing the power adapter close to both sides of the host.) There is no strong magnetic field within 20cm around the antenna. Electric circuit (AC220V); (including the left and right sides of the antenna, above the antenna, the strong electric dark wire embedded in the wall where the antenna is located, etc. If it cannot be prevented, please try not to be within 10cm of the antenna)
The installation height of the shield is preferably not less than 1.8 meters above the ground.
When the azimuth interval of the device is less than 200 meters from the base station, the shielding effect is inversely proportional to the distance from the base station. That is, the closer the base station, the smaller the shielding radius.
Tighten the antenna before turning on the power. The antenna should be kept vertical (⊥). The numbers marked on the antenna should correspond one-to-one with the numbers marked on the antenna hole on the main unit. Do not insert it wrongly, and do not directly turn on the power supply of the main unit without connecting the antenna.
