Smart jammers are often used in school examinations, prisons, hospitals and other places, but the choice of smart jammers is also very particular. Do you know how to choose smart jammers?

1. Before purchase, you need to know which signals to shield. You can choose to shield 2G, 3G, 4G and 5g mobile phone signals. If you only shield 2G, 3G or 4G and 5g, this can be adjusted according to customers' needs before leaving the factory. We can meet the customization of the full frequency band.

2. As for the use place of the smart jammer, it can be applied to the examination room, conference room, office, etc. when it is used indoors. If it is an outdoor open area, it is necessary to use medium power or high-power smart jammers to reach an appropriate distance.

3. The smart jammer can generally be divided into low power, medium power and high power, with the power between 10W and 100W. We recommend that the user select the smart jammer according to the actual shielding area.

4. The shielding range is directly proportional to the power. Generally, low-power signal shielding devices are often used in the examination room, and one is enough for each classroom. For high-power smart jammers, the shielding distance can reach 300-400 meters, which can be selected according to the local field strength.

5. Generally speaking, small smart jammers are relatively small in size. They are similar to notebook computers and are more convenient to use. The volume of high-power trailer type is very large.
