Low power GPS signal jammer is a small shielding product

Gleason Arliss 2022/09/15

  The shield scans from the low-end frequency of the forward channel to the high-end frequency at a certain speed during operation. The scanning speed may cause confusion and interference to the message signal received by the GPS, and the GPS cannot detect the normal data transmitted from the base station so the GPS cannot establish a connection with the base station. GPS is shown as searching the network, no GPS signal, no service system.

  The large shielding range of the jammer can be divided into four situations:

Low power GPS signal jammer is a small shielding product

  In the first type: laboratory data, the shielding range of the low-power GPS jammers is 0~50 meters, and the area is about 10~250 square meters (non-fixed value, the shielding effect is different according to the distance) from the base station, the shielding range is mainly by the magnetic field strength decision). The low-power GPS signal jammer is a small shielding product that is only suitable for open areas and has a weak ability to penetrate walls.

  The second type: There is no base station within 500 meters, one test room within 100 square meters is enough, 2~3 sets of lecture halls are needed for 200-300 square meters; one conference room is installed within 100 square meters, and two sets are installed within 200 square meters. and 600 paperback four. Installing more than 3 units in one area will produce a cellular shielding effect and supplement the dead space.

  The third type: when the magnetic field is weak, install one in 2.5 classrooms. If there are 10 classrooms in a row, 3 can be installed in the aisle; in addition, if the floor of the teaching building is a double-row classroom, then you will be wiped out because the external GPS signal jammer is an omnidirectional antenna, centered on the machine, 360-degree shielding, three are installed in the aisle.

  The fourth type: when the magnetic field is strong, there are base stations within 500m, 300m, 200m, and 100m, and on the roof of the building. The more dots on the shield.

  It is understood that GPS signal shielding The transmitter market can only limit the GPS signal within 500 meters of the transmitter. The shielding radius is adjustable, and the coverage can reach more than 30 square meters. The GPS signal blocker can only block the GPS signal and does not affect other electronic devices. Power saving, power 12W-480W.
