In the scene where the mobile phone shielding device is used to shield the mobile phone signal indoors, even if the same signal jammer is switched to the scene in different places, it is often seen that the shielding effect is very different. The shielding effect of some rooms can reach 15-20 meters, while some rooms may only be 3-5 meters. What factors affect the shielding effect of the mobile phone shielding device?
The factors that affect the shielding distance of the shielding instrument mainly include several: 1: The distance of the surrounding base station and the orientation of the antenna board on the base station; 2: Whether there is any block or attenuation by buildings or other obstacles between the surrounding base station and the site; 3 : The transmit power of each frequency band module of the mobile phone shielding device and whether it is output normally; 4: The erection height and erection position of the shielding device on site; 5: Use the site's own wall material, door and window opening size, and door and window orientation; 6: Inside the unit Or whether there is a signal amplifier installed in the corridor of the building;
How to improve and strengthen the shielding effect of the mobile phone shielding device when the shielding effect of the mobile phone shielding device is not satisfactory after using the field test? This must be solved according to the following steps: first, identify or confirm that the shielding device itself has no quality problems and is working normally (for example, if the shielding device is replaced in other environments, the shielding effect is relatively normal), and then confirm the use of the shielding device The distance of the base stations around the site and whether there is a signal amplifier. It is generally recommended that there should not be a large base station within three or four hundred meters or that the base station (mobile phone signal tower) can be directly seen within the line of sight. If there is a signal amplifier, it is recommended to turn off the amplifier and then test the mobile phone shielding device. After completing the above two steps, analyze the height and installation environment of the shielding device. It is recommended that the installation height of the shielding device is 1.8m-2.5m, so that the signal of the shielding device can be directly transmitted and covered as much as possible to avoid objects. Blocking the signal produces signal refraction and reflection. In addition, if the direction of the signal from the base station entering the room is analyzed, it is recommended to install the mobile phone shielding device on the wall on the side of the window where the signal from the base station enters the room.
