Although the signal brings convenience to many people, and in many cases the function of the signal is also very strong, but the limitation of the signal is that it can form some interference. In order to reduce the interference caused by the signal, the test room shield can effectively shield the mobile phone signal, so that the mobile phone does not need to shut down, avoiding some more troublesome operations.

1. When the site area is larger than the effective shielding range, it is recommended to install multiple shielding devices. Since the power supply and antenna are specially designed to support the host, do not use them interchangeably when factory debugging. _

2. The frequency emitted by the test site shield interferes with the frequency of the mobile phone receiving base station. The relationship between the shield and the base station is bound to be a race. If the transmission power of the signal shield is less than the transmission power of the base station to the mobile phone in the current environment, the shield can not be shielded, only the signal can be shielded.

3. How many meters a shielding layer can shield depends not only on its transmission power, but also on the distance of the base station in the usage environment. It also plays an important role in building and signal amplification, which is done in some buildings. Of course, the effective coverage of the shield is not a specific value, but may also be affected by some factors. When we use it, we can check the shielding effect of the device by checking the mobile phone, and whether the current environment is in a certain range. _

Therefore, at a certain transmission power, the field strength in the interference area affects the interference range, no matter how large the device is, as long as the transmission power is a fixed value, as the distance increases, the interference signal strength of the device will gradually decay, thus losing its interference ability. This is why the interference range is also different under different signal field intensities.
