Sometimes cell phone jammers are essential, but sometimes they can be superfluous. Sometimes GPS can help people. Sometimes GPS is really bad, for example, it’s used for tracking. So there are two sides to the matter. Today’s social and economic development is getting faster and faster, and the progress of science and technology is obvious to all. The 4G era has replaced 3G and 2G as a reality. 5G is already here. But at this stage, 4G data signals still exist as the mainstream. So, can cell phone jammer only block 4G data signals? This is a very important question. In fact, the new signal jammers on the market at this stage have been upgraded, and shielding 4G data signals is basically standard. However, some cheap mobile phone jammers on the market can only block 2G or 3G data signals.
5G signal jammers have many different names such as signal shielding, cell phone shielding, signal jamming, data signal influencer, data signal shielding, mobile communication technology signal jamming, data signal shielding, cell phone signal shielding, signal shielding, wireless communication signal shielding .
For the upper and lower safe channels of the mobile phone system, select memory overclocking, frequency division, frequency hopping filtering and other technologies to analyze the necessary shielding frequency; customize the spherical shielding indoor space according to the signal shielding output power, and automatically generate shielding electromagnetic fields within a specific range, so that the mobile phone ( Including PHS-PHS GSM-Unicom, China Mobile, CDMA-China Telecom) in the indoor space here. When the signal shield is working, it can make the data signal sent and received by the mobile phone in a specific range invalid, and cannot dial and dial, so as to achieve the purpose of compulsory prohibition.
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 baud rate and configuration. The signal shield passes the low-end frequencies of the wireless channel at a certain speed throughout the operation. This scanning speed may result in error codes when the phone receives a data signal in SMS format. The mobile phone cannot detect all the normal data information sent by the communication base station, so that the mobile phone cannot establish a connection with the communication base station. The mobile phone is mainly manifested in the search network, poor signal, no service system and so on.
