Four-point method to determine the shielding range of mobile phone signal jammer
When installing a cell phone signal jammer in the corresponding venue, we often need to install it according to the corresponding shielding range and surrounding environment, so how to judge the shielding range of the mobile phone signal jammer? There are mainly the following four points, together with the mobile phone signal jammer manufacturers. Let's find out:
1: Laboratory data, the shielding range of low-power mobile phone signal jammers is 0~50 meters, and the area is about 10~250 square meters (non-fixed value, according to the distance of the site from the base station, the shielding effect is different, and the shielding range is mainly determined by the strength of the magnetic field. ). Low-power mobile phone signal jammers are small-scale shielding products, only for open areas, and have weak ability to penetrate walls.
2: There is no base station within 500 meters, one test room within 100 square meters is enough, 2~3 sets are needed for a lecture hall with a size of 200 square meters to 300 square meters; one meeting room is installed within 100 square meters, two sets are installed within 200 square meters, Four units are installed flat. Installing more than 3 units in an area will form a honeycomb shielding effect, complementing the dead angle.
3: When the magnetic field is weak, install one in 2.5 classrooms. If there are 10 classrooms in a row, it is OK to install 3 in the aisle; in addition, if the floor of the teaching building is a double-row classroom, you will be wiped out, because the external mobile phone signal The shield is an omnidirectional antenna, which is shielded 360 degrees with the machine as the center, and 3 sets are also installed in the aisle.
Four: When the magnetic field is strong, there is a base station within 500 meters, a base station within 300 meters, a base station within 200 meters, a base station within 100 meters, and a base station on the roof. The more points will be.
