How effective can a wireless jammer be?

  • 2022-06-05

The shielding range of wireless jammers varies according to the power of products. The shielding radius of high-power signal shielding equipment used in prisons can reach hundreds of meters, while the shielding radius of low-power shielding equipment suitable for examination rooms and conference rooms is generally between 1-10 meters, mainly depending on the strength of nearby signal base stations.

The high-power signal shielding equipment has very strong shielding ability and is suitable for special occasions such as prisons and detention centers. However, due to its strong shielding ability, if it is close to residential areas, it will inevitably affect the normal mobile phone call needs of nearby people. Therefore, high-power signal shielding equipment is generally used in open places far away from residential areas.

On the contrary, the shielding radius of low-power signal shielding equipment is between 1-10 meters, because the shielding effect of the shield mainly depends on the signal strength of the place of use. If multiple signal base stations are set up in the campus of a school, and the receiving level of the mobile phone is too large, the actual shielding of the shield will be greatly shortened. If there is no base station in the campus, the shielding effect of the wireless jammer will be very good. The shielding distance of 10 meters is no problem. It is enough to put a shield in one examination room.

As more and more mobile signal transmitting base stations are installed in cities, the overall signal strength is getting better and better. So that the original wireless jammer can realize the shielding range with a radius of 10 meters. Now, the shielding effect of the same machine may be reduced.
