5G signal jammers have many different titles, signal jammers, mobile phone jammers, signal jammers, data signal influencers, data signal blockers, mobile phone isolator, mobile phone disconnector, mobile communication technology signal Jammer, data signal shielding device, mobile phone blocker, data signal blocker, mobile phone blocker, data signal blocker, mobile phone signal isolator, signal isolator, data signal disconnector, wireless communication signal jammer.
For the uplink and downlink security channels of the mobile phone system, it selects technologies such as memory overclocking, frequency division, and frequency hopping filtering to analyze the necessary shielding frequencies; according to the output power size of the signal shielding device, a ball-shaped shielding indoor space is customized, The electromagnetic field is automatically generated and shielded in a specific area, so that mobile phones (including PHS-PHS-GSM-Unicom, China Mobile Communications, CDMA-China Telecom) are invalid on the mobile phone in an indoor space here. When the signal jammer is in operation, it can invalidate the function of receiving and sending data signals by mobile phones in a specific category, and cannot dial out and dial in, thereby achieving the purpose of compulsory prohibition.
The basic principle of the 5G 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 the data information and sound transmission are carried out with a certain serial port baud rate and deployment method.
The basic principle of mobile phone signal jammer communication, the signal jammer passes to the middle and low end frequency of the wireless channel at a certain rate during the whole process of work to the high-end scanner. The rate of the scanner can produce error codes in the message format data signal received by the mobile phone. The mobile phone cannot check all normal data information transmitted from the communication base station, so that the mobile phone cannot establish a connection with the communication base station. The main manifestations on the mobile phone are the search network, poor signal, no service system, etc.
Before purchasing a 5G signal jammer, everyone must pay attention to some practical elements:
1. The total area of the application. The shielding category of 5G signal jammer is based on the size of the output power of the signal jammer. If it is detected in the field according to the level of the local natural environment data signal, the shielding category is different. For example, the data signal in the room is weakly shielded. , Outdoor application accessories have GSM communication base station which, so the GSM data signal is shielded in the outdoor field, the principle is close!
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 shield. The general data signal (2345G) is alternatively shielded. If you only shield 23G Or just shield 34G, which can be adjusted before the original factory. In addition, there are 2.4gWIFI, 5.8GWIFI and other frequency bands. General data signals can all be quickly shielded.
3. The category of frequency. Shield the frequency band: CDMA800, GSM900, SCDMA1800, DCS1800, PHS1900, TD-SCDMA (Mobile 3G), CDMA2000 (Telecom 3G), WCDMA (China Unicom 3G).
