A customer wanted to buy a wireless signal jammer from us, and described their installation and use environment: their unit is a three-story building, the first floor is the factory workshop, the second floor is the office area and meeting room, and the third floor It is workshop and warehouse. After the wireless signal jammer was purchased, it was ready to be installed in the meeting room on the second floor, but there was a key requirement: the shielding range was limited to the meeting room, and it could not affect the wireless signals on the upper and lower floors and the normal use of mobile phones. Then the question arises, is it possible to install a wireless signal jammer in the conference room on the second floor without affecting the first and third floors?

If it is absolutely necessary to guarantee that it will not affect other floors, it is basically impossible. Because the transmission mode and transmission characteristics of the wireless signal determine that it cannot achieve a one-size-fits-all effect, that is to say, the shielding signal emitted by the wireless signal jammer, its transmission boundary is impossible to use the walls around the conference room as the boundary And the deadline. Although the floor and ceiling of the meeting room are solid floor partitions, the RF signal will experience a very large attenuation when it penetrates the floor, but after all, there will still be a certain amount of signal that can penetrate through it, but the energy and intensity are much reduced. That's all. On the other hand: there are different numbers of doors and windows on the walls around the meeting room, and the shielding signal of the wireless signal jammer will have different degrees of refraction and reflection when encountering walls, doors, windows, etc. in the meeting room. There are even direct transmissions to the outside world through doors and windows. The attenuation caused by this phenomenon is not large, and it will inevitably have a certain impact on other rooms on the upper and lower floors. If you want to ensure that the first and third floors are not affected, there is a simple and crude way: completely seal the conference room with a metal plate, the characteristics of the metal plate can make the jammer number of the wireless signal device almost completely blocked in the closed area. inside the cavity space. But it is obvious that this solution is completely unacceptable and does not have practical operability.

When the wireless signal jammer is installed in the meeting room on the second floor, we can only look at this problem from the perspective of minimizing its impact on the upper and lower floors. How to minimize the impact? The method can still be provided for reference: first, install the wireless signal jammer as far away as possible from the window side of the outer wall, that is, install the jammer as far as possible inside the building. Secondly, manufacturers of wireless signal jammers are required to configure directional antennas for the equipment. Finally, confirm that the conference room is made of reinforced concrete walls, and try to avoid walls of gypsum boards or walls of glass partitions.
