When some customers inquire about wireless jammer products, they often only ask how much coverage they need and a psychologically affordable price. But when it comes to in-depth technical docking or recommendation of specific product models, it is easy to be surprised by the price difference. Why is this? In fact, the customer does not know the correspondence between the transmission power and the coverage of the wireless signal interference. A large coverage area is often proposed, which actually requires the use of high-power interference equipment to solve the application requirements, but the psychologically expected price is only the corresponding low-power interference equipment. As everyone knows, in the field of signal interference, The price difference between high-power and low-power products is very huge, and the difference is not a little bit. So, how is the transmission power of the wireless jammer divided into grades? Here we will explain in detail:

Here we take the most common wireless jammers for mobile phone applications as an example. Usually, it can be divided into 4 grades according to the size of the transmit power:

1. Micro-power file: refers to the transmission power of each frequency band at 0.5-1W. This kind of wireless jammer is mainly palm-sized and hand-held. It is characterized by small size and light weight, but at the same time its effective coverage is also very limited. , generally only suitable for use in indoor environments, and its radius of action is within the range of 1-5 meters;

2. Low power file: It means that the transmit power of each frequency band is 2-5W. This kind of wireless jammer is the most common and has a very high cost performance. Most manufacturers make its appearance as a desktop type or wall-mounted type, which is basically only a It is limited to use in indoor environment, and its action radius is within the range of 5-20 meters;

3. Medium power file: This means that the transmit power of each frequency band is around 10-20W. When the wireless jammer reaches the medium power level, it basically has the conditions for outdoor application, and of course it is also suitable for indoor application, such as some large transparent spaces, such as theaters, venues, workshops, etc. Its effective radius can reach 20-50 meters;
