5G signal jammer has many different names, signal jammer, mobile phone jammer, signal jammer, signal interference device, signal blocker, mobile phone isolator, mobile phone disconnector, mobile communication signal Jammer, signal blocker, mobile phone jammer, signal jammer, mobile phone blocker, signal blocker, mobile phone signal isolator, signal isolator, signal disconnector, wireless communication Signal jammer.

For the upstream and downstream channels of the mobile phone system, it uses memory overclocking, frequency division, frequency hopping filtering and other technologies to analyze the necessary shielding frequencies; it customizes a spherical shielding space according to the power size of the signal jammer, Automatically generate electromagnetic shielding within a specific range, making mobile phones (including PHS - PHS, GSM - China Unicom, China Mobile, CDMA - China Telecom) invalid on mobile phones in this space. When the signal jammer is in operation, it can invalidate the signal receiving and sending functions of mobile phones within a specific range, making it impossible to dial in and out, thus achieving the purpose of forcibly prohibiting use.

5g jammer

The basic principle of the 5G signal jammer: Within a certain frequency range, the mobile phone and the communication base station are connected through electromagnetic waves, and data and sound are transmitted at a certain serial port baud rate and deployment method.

The communication principle of the cell phone blocker is that the signal jammer transmits the low-end frequency of the wireless channel to the scanner at a certain rate during the working process. This scanner speed may cause errors in the packet signal received by the mobile phone. The mobile phone cannot detect any normal data transmitted from the base station, making the mobile phone unable to establish a connection with the base station. The main symptoms on the mobile phone include network search, poor signal, and no service system.

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

1. Total area of application. The shielding range of the 5G signal jammer is based on the size of the signal jammer's output power. If the shielding range is different according to the local environmental signal level during on-site testing, for example, if the signal in the room is weak, the shielding range will be larger. , outdoor accessories include GSM communication base stations, etc. So the GSM signal is shielded outdoors based on the principle of proximity!

2. Output power size. As everyone knows, 2G, 3G, 4g and 5G: before purchasing, you need to know what signal you want to block. General signals (2345G) can be blocked instead. If you only block 23G Or only block 34G. This can be adjusted before the original factory. In addition, there are also 2.4gWIFI, 5.8GWIFI and other frequency bands. Generally, ordinary signals can be blocked quickly.

3. Frequency range. Block out frequency bands: CDMA800, GSM900, SCDMA1800, DCS1800, PHS1900, TD-SCDMA (Mobile 3G), CDMA2000 (Telecom 3G), WCDMA (China Unicom 3G), etc.
