During the exam, it is very important to ensure that the jamming device is normal and useful and can play a shielding effect. When many people buy wifi jammer for exams, they often encounter jammers of different prices. How to judge these and whether they are worth so much money?
What is the relationship between power and the price of wifi signal jammer?
1. What is the actual power? For each power, the corresponding electronic components are different. Especially for some high-power products, electronic components will be very expensive to achieve that effect.
2. How many volts does it depend on? Just like, you are a 1.0 displacement car, your power is the same. If it is a 5v power supply, it will be very difficult to achieve 24w or 36w.
3. Look at the shell. Is it a metal shell, a metal shell, or an aluminum alloy shell? With different shells and opened molds, the price is not the same.
4. A little more detail is to look at the design of each module. The general manufacturer is the same module, changes the shell, and makes a shield with different power.
The price of a wifi signal jammer varies according to different uses. For example, GPS cell phone signal jammers are specially used for mortgage car services, and the price is very cheap about 150 yuan. Small power and medium power, high power, the price will be a little more expensive.
The price of low power is between 300-700 yuan, the price of medium power is about 700-1000 yuan, and the price of high power is more than 1200 yuan. The price of the built-in wifi frequency jammer will be relatively high, such as the one that hangs on the wall, the price is very cheap, because the shell of the built-in wifi jammer device is plastic and the cost is relatively low, and the outer shell of the wifi bluetooth jammer is relatively cheap. It is aluminum alloy.
