The performance of mobile phones is getting stronger and stronger, is the full-band signal jammer still effective?

Now that the functions of mobile phones are getting more and more powerful, sometimes it feels that the computer is useless, but in fact, the signal of the mobile phone can be blocked, and it will have no effect if it is blocked. The performance of the mobile phone is already so powerful, can the full-band signal blocker still block the mobile phone signal?

1. The location of the signal base station

The distance between the base station and the mobile phone is also one of the factors to consider when purchasing a full-band signal jammer. If the base station is far away, one is enough, but if the distance has fallen below 300 meters, it will be another matter. , it may not be enough to have a full-band wifi jammer in one examination room. It may be necessary to increase the number of full-band signal jammers, or replace them with high-efficiency full-band signal jammers.

2. It is related to the strength of the magnetic field

When the magnetic field is not strong, it is enough to use two for five classrooms. If it is a double-row classroom, it is even better. Two 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 full-band signal shielding device should be used, or the number should be increased to increase the shielding effect.

3. The power of the full-band signal jammer

The power of the full-band signal jammer is relatively small, and the range of the shielded signal is also small, and the low-power full-band GPS Jammer has poor wall penetration ability, and basically has no effect across the wall, which means that it can shield the signal. It depends on whether the full-frequency signal jammer you buy can match your location, and it needs to be in an open area.
