When some customers inquire about wireless wifi 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 corresponding relationship between the transmission power and the coverage of the wireless wifi signal jammer. A large coverage area is often proposed, which actually requires the use of high-power shielding equipment to solve the application requirements, but the expected price is only the corresponding low-power shielding equipment. As everyone knows, in the field of signal shielding, 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 wifi signal jammer divided into grades? Here we will explain in detail:
Here we take the most common wifi blocker 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 between 0.5-1W. This wifi jammer device 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 gear: It means that the transmit power of each frequency band is 2-5W. This kind of wifi signal blocker is the most common and has a very high cost performance. Most manufacturers make its appearance as a desktop type or wall-mounted type, basically It is also limited to use in indoor environments, and its radius of action 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 wifi frequency jammer reaches the medium power level, it basically has the conditions for outdoor application, 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;
4. High-power gear: This means that the transmit power of each frequency band reaches 50W or 100W. This power level wifi blocker is completely suitable for outdoor applications, such as towers in large prisons, protection of large oil depot areas, etc. It is also suitable for mobile work scenarios after vehicle modification.
