SIGNAL JAMMER

Of course, the size of the wall penetration ability is also related to the transmit power of each frequency band of the mobile phone jammer. Generally speaking, the larger the transmitting power, the stronger the penetrating ability. It is the same as listening to the sound of the next door through a wall. If the sound of the next door is louder, you can hear it clearly. won't hear it.

We all know that the lower the frequency of the wireless signal, the stronger the diffraction performance, just like the radio stations that everyone usually listens to. The frequencies emitted by radio stations are basically tens of megabytes to more than 100 megabytes, and the frequency is very low. One transmission tower can cover more than 100KM. The lower the frequency of the wireless signal, the stronger the penetration ability will be.

Therefore, when using a mobile phone signal jammer, if it can be determined that the wall is made of gypsum board and wood board, then you can choose whether to install it on a partition wall. If the wall is made of brick or steel, it is not recommended to install a mobile phone jammer on the partition wall. Recently, at the request of university users, on-site investigation was carried out, and on-site interference range detection was carried out. After testing, the interference effect of the mobile phone jammer on telecommunications and China Unicom can meet the signal interference of the entire classroom, but the interference range for mobile phones is very small, only two or three meters.

During the inspection by technicians with professional equipment, it was found that a large number of antennas for indoor signal distribution were installed in the ceiling of the corridor of the teaching building, and after inspection, it was found that the indoor signal distribution system was indeed installed by mobile, which caused the interference of mobile phones. The reason why the device does not interfere with the mobile phone in the classroom is not good.

At present, domestic operators will configure base stations and indoor signal amplification on campuses of colleges and universities. This is because the capacity of each base station and indoor signal amplification is very limited, and there are many teachers, students and faculty members in colleges and universities, so they must be on campus. Configure the base station and indoor signal amplification. Everyone knows that the size of the interference range of the mobile phone signal jammer is closely related to the distance of the base station and whether indoor signal amplification is installed in the teaching building.
