Mobile phone signal jammers are divided into the following situations according to the shielding range and the port data used:
The first type: within a small range of 0-10 meters, with an area within 120 square meters. Low-power mobile phone signal jammer. The shielding effect is different according to the distance between the location and the base station, and the shielding range is mainly determined by the strength of the magnetic field. Can recommend handheld 4-way and 6-terminal cell phone jammer. Low-power shielding through walls will weaken the signal. If you need to go through walls, it is not recommended to buy low-power ones.
The second type: there is no base station within 1 km. Within 120 square meters, one is enough. Two units are recommended for 120-250 square meters. It is recommended to install one for large conference rooms within 150 square meters, two for 250 square meters, and four for 600 square meters. Installing more than 3 units in an area will form a honeycomb shielding effect.
The third type: how many meters can be shielded by the jammer is not only related to its own transmission power, but also to the distance of the base station in the environment (base stations are not limited to large-scale transmission towers built on the ground, but also on the roof The signal amplification antenna and the signal amplification distribution in some buildings). Another important factor is obstacles. If it is a metal material, it will be directly blocked; if it is a solid reinforced concrete wall, it will be attenuated by at least 10 times after penetration.
The fourth type: the strength of the magnetic field signal. When the magnetic field is weak, install one in 2.5 classrooms. If there are 10 classrooms in a row, install 3 in the aisle; when the magnetic field is strong, there are base stations within 500 meters, base stations within 300 meters, base stations within 200 meters, and base stations within 100 meters. The base station, there is a base station on the roof, it can only depend on the situation, the stronger the magnetic field, the more points need to install the mobile phone signal jammer.
Therefore, when installing a mobile phone signal jammer, you must first understand your surrounding environment and the area to be used before deciding which type of jammer to buy.
