I believe everyone is familiar with signal jammers for cell phone. Nowadays, various jammers appear on the market non-stop. Everyone claims that their jammers are very good, and all jammers have their effectiveness. The shielding range, then, what determines the effective shielding range of the jammer? Let’s take a look together below.
1. The power of the jammer body. There are many bodies on the market today that are said to be 5W, but the actual power is not even 1W. Therefore, it must be actual power. For low-power bodies within 1W, the shielding range is about 1-10 meters, and the shielding range is 10-30 square meters. Remember, this kind of fuselage cannot penetrate walls.
2. The density of base stations around you. Nowadays, many customers have bought the phone and can block 2G and 3G calls, but not 4G. What's going on? In fact, it is because there are base stations around you. Usually there are base stations within 100 meters. If you buy a low-power camera, it basically won’t work because the base station’s signal strength is too strong. It is recommended to buy a cell phone signal jammer with medium power, accounting for above 2W per channel. There is a customer who has a mobile base station installed on the roof, which means that the equipment does not work. This is difficult for anyone to solve. Unless you buy a very powerful machine.
3. Field wall environment. What exactly is a field wall environment? This is where you install the cell phone signal jammer, either on a cement wall or a glass partition. Ordinary jammers have no effect if they penetrate the wall. Like many customers, come to consult us. If a child hides in a room and plays games alone, can there be a partition that can shield the child? The price should be low. In a situation like this, it is difficult to do. Generally, the price of wall-penetrating shielding meters is very high, at least 700 yuan or more.
Based on what has been said above, the shielding range of a signal blocker is not determined by a single factor. It is recommended that before purchasing in batches, the best way is to use a field wall meter to test the signal level of your installation environment. Another one is to buy a few fuselages with different powers, test them, see how they work, and then decide which fuselage to choose.
