First, the appearance is compared to the shield

It's not particularly critical, it's just that the setting structure is different. External antennas can be divided into external antennas and internal antennas. The external antenna occupies a larger space volume than the internal antenna because the external antenna is connected to the external antenna and bends and stretches outward; the actual effect of the external antenna is more stable because the wireless antenna expands outward.

Second, the power size of the shielder

The general power range is 3W-480W. Jammers can generally be divided into low power, medium power and high power. The power is in the middle of 3W-100W. Generally, it is not recommended to use high-power signal jammers, which will seriously affect the base station signal transmission. The body is also a source of radiation to a certain extent. For tests, colleges, national judicial examinations, etc., it is recommended that some small and medium-sized power machines be strongly recommended.

Third, the size of the power supply system

The handheld one has a built-in lithium-ion battery. After the power is used up, you can use the adapter battery to charge it; the desktop all-in-one examination room uses a 220V working voltage power supply system, and the vehicle-mounted type used in the car generally uses a 12-36V working voltage power supply system. system.

Fourth, the application venue

If it is used in indoor venues, generally the shields suitable for examination rooms, conference halls, conference rooms and other areas are low-power, and the gas filling station must be explosion-proof and heat-resistant; if it is an outdoor spacious area, high-power must be used Only with a signal jammer can the appropriate spacing be achieved. Especially if it is necessary to cross the wall.

Fifth, regulations on working frequency

In fact, it is what everyone is familiar with, 2G, 3G, 4G and 5G: before purchasing, you need to know what signals you want to block. General signals (2345G) can be selectively blocked. If you only block 23G or only 45G , this one can be adjusted before shipment, and the other one also has 2.4GWIFI, 5.8GWIFI and other frequency bands. Generally speaking, ordinary data signals can be blocked quickly.
