The functions of mobile phones are getting stronger and better, does the mobile phone signal jammer still have an effect on it?
As the functions of current mobile phones are getting more and more powerful, does the mobile phone signal jammer still have an effect on it? If you want to know more, then follow our editor to learn about it today!
1. The size of the shielding instrument power
The power of the mobile phone signal shielding device is relatively small, the range of the shielding signal is also small, and the low-power signal shielding device has poor wall penetration ability, and basically has no effect across the wall, which means that it can shield the signal. Can the shielding device you buy match your location, and it must be in an open area.
2. The location of the signal base station
The distance between the base station and the mobile phone is also one of the factors that should be considered when purchasing a shielding device. If the distance between the base station is relatively far, one is enough, but if the distance has fallen below 500, it will be another matter, maybe one in each test room. The shielding instrument is not enough, it may be necessary to increase the number of shielding instruments, or replace the signal shielding instrument with high efficiency.
3. It is related to the strength of the magnetic field
When the magnetic field is not strong, it is enough to use two units for five classrooms. If it is a double-row classroom, it is even better. Two units are used for ten classrooms, which saves trouble and money. However, in a place with a strong magnetic field, the magnetic field affects the direction of electromagnetic waves, so the signal shielding effect will be very poor. At this time, a stronger shielding device should be used, or the number should be increased to increase the shielding effect.
