Wifi blocker considerations? I believe that many people have doubts, in the end what should be considered in the choice?
1. Shield frequency band
Before purchasing, you must know which signals you want to shield. The usual mobile phone signal (234G) can be selectively shielded. If you only shield 2, 3G or only 3, 4G, this can be adjusted before leaving the factory . And our company's mobile phone signal shielding device uses full-band shielding. If users need to shield a certain signal, they only need to install the corresponding antenna on the machine;
2. Applicable occasions
Regarding shielding applications, if it is used indoors, it is usually a type of mobile phone signal shielding device suitable for examination rooms, conference halls, offices and other spaces. Gas stations must use explosion-proof and high-temperature resistant ones; Only medium-power equipment can achieve suitable spacing;
3. Appearance
In appearance, the wifi jammer can be divided into an external antenna and a built-in antenna. Generally speaking, the external antenna extends outward because the antenna is external, so it occupies a larger space and size than the built-in antenna; Because of the extended antenna, the effect of the external antenna is stable;
Fourth, the size of the power
Jammers can usually be divided into low-power, medium-power, and high-power, and the power is 3W-100W. When we recommend users to choose a wifi jammer, it will be determined by the total area required for shielding;
5. Shielding range
The shielding range is directly proportional to the power. Usually, there are many applications in the examination room. A low-power mobile phone signal jammer is enough to install one in a classroom. 300-400 meters, depending on the local field strength;
6. Body type
Generally speaking, the smaller one must be handheld and portable, which is relatively small in size and easy to carry; the low-power desktop type is usually not very large in size, similar to a small notebook computer; the high-power one is relatively Speaking of heavy, the body of the drag box is particularly large;
7. Power supply
The handheld wifi jammer is a built-in lithium battery, which can be charged with a power adapter after the electricity is used up; the test room of the table type uses a 220V voltage power supply, and the vehicle-mounted application is usually a 12-36V voltage power supply.
The above are the considerations when purchasing a wifi blocker, I hope it will help you after reading!
