Now basically everyone has their own mobile phones, and mobile phones have become a necessity for each of us. Nowadays, the functions of smart phones are getting stronger and stronger, and there are more and more APP applications. Sometimes it feels that computers have long become a decoration, but in fact, the signals of mobile phones are still easily interfered by some unknown interference. After the mobile phone is interfered, it will have no effect, just like a brick. In fact, the emergence of this situation is inevitable, but some people still have concerns about this. Nowadays, the functions of smart phones are getting stronger and stronger. Will the data signals be blocked by mobile phone signal blockers?
1. According to the location of the base station
When buying a mobile phone signal blocker, the distance between the mobile base station and the mobile phone is one of the issues to be considered. For example: in a remote area from the base station, one is enough, but if the shielding range is within 300 meters, it is another matter. Generally, in this case, one mobile phone signal blocker in an examination room is not enough. It is very likely that the total number of signal blocking devices needs to be increased, or replaced with a mobile phone signal blocker for sale with a higher power.
2. It depends on the size of the magnetic field nearby
If we are in a place with a weak magnetic field, generally 5 classrooms can use two or so devices. If it is a single or double row classroom, it is better. 7 or 8 classrooms use two, which is convenient and cost-saving. However, if it is a place with a high magnetic field, the magnetic field affects the direction of radio waves, so the signal shielding effect will be relatively poor. At this time, a more powerful mobile phone signal blocker should be used, or the number should be increased to improve the shielding effect.
3. It depends on the power of the mobile phone signal blocker
The power of the mobile phone signal blocker is very small, so the power range of the shielded signal is also small, and the low-power mobile phone signal blocker has poor wall-penetrating ability, and it is basically ineffective across the wall. In other words, whether the signal can be shielded depends on whether the cell phone blocker you buy is consistent with your location, or whether it is in an open area.
