During the investigation, it is very important how to ensure that the shielding device is normal and useful, and can achieve the shielding effect. When many jammers buy, they often buy shields with different prices. How can they be judged? Is it worth that much money?
First, let's make the relationship between price and power known. The wifi jammer is divided into low power, medium power and high power.
Low power, ie within 2W, these 2W refer to 2W per channel. If it's 8 channels, the shield is also 16W. This is suitable for home use, small meeting room, etc., usually within 15 square meters.
Average power refers to between 2W and 4W. If each channel is 4W, 8 channels is 32W. This can generally be counted as average power. This is suitable for examination rooms, gas stations, etc. In general, the shielding area is relatively large.
High power refers to over 5W, if it is 8ch, it means the machine is over 40W. This power is very great. Applicable factories, etc.
Currently on the market, many fake power machines are generally powered by 5V, which is also known as 24W or 36W. This means that the car you originally drove had a displacement of 1.0, but you literally wrote a displacement of 3.0 in the advertisement. From a consumer capital perspective, the larger the shift, the higher the cost performance.
What is the relationship between the rate and the price of the shield?
1. Look at the shell. Is it a metal shell, hardware shell or aluminum alloy shell? Different bowls and shapes have different prices.
2. Take a closer look at the design of each module. Generally, manufacturers use the same module, change a hull, and make shields with different performances.
3. What is the actual performance? For each power, the corresponding electronic components are different. Especially for some high-performance products, electronic components are very expensive to achieve this effect.
4. How much power supply depends on it? Just like a 1.0cc car, your performance is the same. If it's a 5V power supply, it's very difficult to reach 24W or 36W.
