Many customers came to ask, what is the shielding range of the wifi jammer , 500 square meters, can it be achieved with two 20W wifi jammers?
The answer is not necessary.
The effective shielding range of the wifi jammer mainly depends on the following points:
1. The power of the machine itself. Now there are many machines on the market that are said to be 5W, but the actual power is less than 1W. So, it must be the actual power. For low-power machines within 1W, the shielding distance is about 1-10 meters, and the shielding range is 10-30 square meters. Remember, such a machine cannot pass through walls.
2. The density of base stations near you. Now many customers buy back the phone, 2G and 3G calls can be blocked, but 4G cannot be blocked. What is the reason? It is because there is a base station near you. Generally speaking, there is a base station within 100 meters. If you buy a low-power machine, it is basically useless, because the signal strength of the base station is too strong. It is recommended to buy a shield with medium power, with a ratio of more than 2W per channel. There is a customer who has a mobile base station on the roof and insists that the wifi jammer is ineffective. No one can solve this. Unless you buy a super-powerful machine.
3. Field wall environment. What is a field wall environment? It is the place where you install the shield, whether it is a cement wall or a glass partition. Ordinary shields have no effect if they pass through walls. Like many customers, come to consult us. If a child hides in a room to play games alone, can there be a partition wall to shield it, and the price is lower? In a situation like this, it's hard to do. Generally, the price of the shielding device through the wall is very high, at least above 700.
To sum up the above, the shielding range of the wifi bluetooth jammer is not solved by a single factor. Before buying in large quantities, the best way is to use a field wall meter to test the signal strength of your installation environment. The other is to buy several machines with different powers and test them to see how they work. Then decide which machine to choose in the end.
