Precautions for assembling mobile phone signal jammer
The cell phone jammer is a new type of data security product. It uses special electromagnetic wave signals to generate an interception net at the maintenance site, so that the mobile phone cannot receive the communication base station data information, and cannot contact the communication base station. Regarding signal jammers, you need to know the following 4 common problems:
What needs to be done before assembling the mobile phone signal jammer:
1. Before assembling this special device, be sure to properly assemble the wireless antenna according to the logo, and then turn on the switch power to avoid the device from being burned.
2. Before assembling special equipment, you must first grasp the position of the communication base station, and make the position of the jammer as close as possible to the position of the communication base station.
3. When assembling special equipment, pay attention to whether there are metal materials within 1 meter around the equipment to avoid generating signal reflection surfaces, which may affect the interception effect.
4. Especially natural environments such as petrol stations, gas stations, etc. should be assembled with explosion-proof equipment.
5. The relative height of the assembly is 1.8-2 meters. It can be directly placed on the table, can be assembled on the wall or on the ceiling. It is better for the wireless antenna to be straight with the road surface.
6. If assembling in a house, you should pay attention to whether the transmission frequency of the wireless network equipment already in the house will cause the same frequency influence.
7. Be sure to consider the tolerance and safety distance of the current meticulous instrument equipment in the house against the influence of different frequencies.
8. If the house is equipped with an amplifier such as WiFi enhancement, it is not suitable to assemble the jammer.
9. Fully grasp the boundaries of the interception area and the non-interception area.
Assemble the mobile phone signal jammer on the spot survey
1. Mastering the receiving sensitivity on the spot is very important for the assembly of the jammer. Since there are many signals in a natural environment, and the strength of various signals is different, mastering the receiving sensitivity on the spot can purposely make and assemble the shielding device.
2. In the absence of special survey equipment, it is required to grasp the situation of communication base stations near the assembly site, estimate the distance between them, and what communication base stations (mobile, China Unicom, CDMA, 3G, 4G, 5G and other communication base stations), communication base stations are Where is the azimuth of the wireless antenna? Usually, communication base stations in cities are mostly built on the roofs of tall buildings, and iron towers are used in suburban or rural areas.
3. If you have special survey equipment, you only need to record the receiving sensitivity of several points inside and outside the house in detail.
Mobile phone signal jammer assembly
1. According to the results of the survey, effective matching of different signals has been achieved, and the most ideal situation has been achieved. The impact level of non-intercepting areas and the impact on nearby communication base stations should be fully considered.
2. Determine the approximate assembly plan. In the operation assembly process, the main assembly signal is the local area (that is, the local area nearest to the communication base station), and the directional antenna is used to start the assembly along the base station antenna.
3. Taking into account the floor height of the interception area, because the high-rise signal is better than the bottom, the assembly sequence from top to bottom is adopted to achieve the interception effect.
4. Taking into account the anti-interference ability of the PHS communication base station, the output power of the PHS communication base station is usually relatively small, and there is no distinction between the uplink and the downlink route of the PHS. The communication base station is easy to absorb interference, and the communication base station cannot be normal. run.
