When using some types of signal shielding devices in daily life, it is necessary to ensure that they do not interfere with communication in other places. The use of these signal shielding products should be reasonable and compliant, ensuring that they meet the needs of signal shielding and other communication requirements. Many people should be very clear that mobile phone communication is transmitted through the signals of base stations, and the coverage of Mobile phone signal in China is relatively high. The three major state-owned operators are sparing no effort to build infrastructure such as base stations to enhance the coverage of Mobile phone signal signals, so that people can receive Mobile phone signal anytime, anywhere, and complete the transmission of signals.

And what frequency jammers do is block the base station signals within a certain frequency band or region, making it impossible for mobile communication devices within the frequency jammer range to transmit signals. Generally speaking, shielding devices are mainly targeted at places such as prisons, public security, military areas, schools, courts, and other places.
When using signal shielding devices, it is necessary to achieve reasonable compliance and not interfere with the normal signal communication of others in order to meet personal signal shielding needs. This is very unacceptable. When selecting frequency jammers, it is necessary to choose professional shielding manufacturers, which not only improves the effectiveness of the shielding device, but also ensures technical support and product maintenance in the future.
