The basic principle of 5G mobile phone signal jammer

5G signal jammers have many different names, signal jammers, mobile phone jammers, signal jammer, data signal influencers, data signal blockers, isolators on mobile phones, disconnectors on mobile phones, mobile communication technology signals Jammer, data signal shielding device, mobile phone shielding device, data signal shielding device, mobile phone blocking device, data signal blocking device, mobile phone signal isolator, signal isolator, data signal disconnector, wireless communication Signal jammers.

For the uplink and downlink security channels of the mobile phone system, it adopts technologies such as memory overclocking, frequency division, and frequency hopping filtering to analyze the necessary shielding frequency; according to the output power size of the signal shielding device, a spherical shielding indoor space is customized. Automatically generate and shield electromagnetic fields within a specific range, making mobile phones (including PHS-PHS-GSM-Unicom, China Mobile, CDMA-China Telecom) ineffective on mobile phones in an indoor space. When the signal jammer is in the running state, it can make the mobile phone in a specific category invalid to receive and send data signals, and it is impossible to dial out and dial in, thereby achieving the purpose of forcibly prohibiting the use.

The basic principle of 5G mobile phone signal jammer: within a certain frequency range, the mobile phone and the communication base station are connected to each other according to electromagnetic waves, and transmit data information and sound with a certain serial port baud rate and deployment method.

The basic principle of mobile phone signal jammer communication, the signal jammer goes to the scanner at a certain rate at the middle and low end frequencies of the wireless channel during the whole process of operation. The scanner rate can cause errors in the mobile phone receiving the data signal in the message format. The mobile phone cannot detect all normal data information transmitted from the communication base station, so that the mobile phone cannot establish a connection with the communication base station. On the mobile phone, it is mainly manifested as searching for the network, poor signal, and no service system.

Before buying a 5G mobile phone signal jammer, everyone must pay attention to some practical factors:

1. The total area of ​​application. The range of 5G mobile phone signal jammers shielded is based on the size of the output power of the signal jammer. If the range is different according to the level of the local natural environment data signal during on-site detection, for example, the data signal in the room is weak and the range is shielded. Large, outdoor application accessories include GSM communication base stations, so the principle of GSM data signal shielding outdoors is close to the scope!

2. The size of the output power. As everyone knows, 2G, 3G, 4G and 5G: Before purchasing, you must know what data signal you want to block. The general data signal (2345G) can be blocked instead. If you only block 23G Or just block 34G, which can be adjusted before the original factory, and there are also 2.4gWIFI, 5.8GWIFI and other frequency bands. General data signals can be quickly shielded.

3. The range of frequency. Block out the frequency band: CDMA800, GSM900, SCDMA1800, DCS1800, PHS1900, TD-SCDMA (Mobile 3G), CDMA2000 (Telecom 3G), WCDMA (Unicom 3G).
