Can the mobile phone jammer with omnidirectional antenna be placed arbitrarily during installation?

Can the mobile phone jammer with omnidirectional antenna be placed arbitrarily during installation?

  • 2022-12-07

Most of the mobile phone jammers purchased by customers are equipped with omnidirectional antennas, which originate from the simple cognition that omnidirectional antennas are omnidirectional signal coverage, so most customers imagine the range of shielded signal coverage as: using mobile phone jammers It is a spherical coverage area emitted from the center of the sphere and diffused from the center to the surroundings. Because of this, customers will take it for granted that the installation method of the equipment is very simple, and there is no need to think too much about whether the installation is correct. Then, the problem arises. The mobile phone jammer of the omnidirectional antenna can be arbitrarily placed during installation. let it go?


This question can be discussed and answered from several aspects. First of all, if the mobile phone jammer is only installed in a small space, such as a room with only tens of square meters, which needs to completely shield the mobile phone signal, then this situation It is relatively simple. When installing a mobile phone jammer in such a room, it is more appropriate to install it without too much consideration, because in such a space where the length and width do not exceed 10 meters, any one In the corner or on any side of the wall, the shielding distance of the mobile phone jammer is enough to cover the entire room.

But if the indoor area of a room reaches 100-300 square meters, then at least one of its length and width will exceed 10 meters, or even reach about 20 meters. The current mobile phone jammer, especially the mobile phone jammer with 5G signal shielding, usually has an effective shielding distance radius of 10 meters to 20 meters. In this scenario, if the mobile phone jammer is still installed in a certain If it is a corner, it is very likely to have such a consequence: the area in the room opposite to the shielding device is very likely to be a place that the distance range of the mobile phone jammer cannot reach. In this area, there will be a blind area that shields the coverage of the signal. How to solve this phenomenon? The solution is simple, and the most effective solution is to adjust the installation position of the mobile phone jammer to the middle position appropriately, and use the signal coverage characteristics of the omnidirectional antenna to shorten the distance from the blind area so that the shielding signal can reach the diagonal. area, while maintaining the signal coverage strength of the original location is still sufficient.
