How wide is the coverage of the vehicle-mounted frequency signal jammer?
In the following content introduction, let's also clarify the effective coverage range of the vehicle-mounted frequency signal jammer.
1. Although the signal has brought convenience to many people, and the effect of the signal is also very strong in many cases, the limitation of the signal is that it will form a certain interference. In order to reduce the interference caused by the signal, the use of a vehicle-mounted frequency signal jammer can effectively shield the mobile phone signal, so that the mobile phone does not need to be turned off, avoiding some troublesome operations.
2. Since the power supply and antenna are specially designed for the host, they are debugged one-to-one during factory debugging, so do not use them interchangeably.
3. The frequency emitted by the vehicle-mounted frequency signal jammer interferes with the frequency of the mobile phone receiving the base station. The relationship between the shield and the base station is destined to be a competition. If in the current environment, the transmission power of the signal shield is less than the channel power transmitted by the base station to the mobile phone, the shield cannot be shielded, and only the signal shield can be shielded.
4. How many meters a shielding layer can shield depends not only on the transmission power of the vehicle-mounted frequency GPS signal jammer itself, but also on the distance of the base station in the use environment. Buildings and signal amplification are distributed in some buildings, and it also plays an important role. Of course, the effective coverage range of the vehicle-mounted frequency signal jammer does not mean that there is any specific value, and it may also be affected by some factors. When we use the vehicle-mounted frequency signal jammer, we can check the shielding effect of the instrument by checking the mobile phone to see whether the current environment is within a certain range.
