5G signal blockers are called in many ways, including signal blockers, cell phone jammers, signal jammers, data signal influencers, data signal blockers, mobile communication technology signal jammers, data signal blockers, mobile phone signal blockers, signal blockers, wireless communication signal blockers, etc.
Choosing a suitable 5G signal blocker requires considering the following factors:
- Safe channel: Analyze the frequency bands required for the upper and lower safe channels of the mobile phone system through memory overclocking, frequency division, frequency hopping filtering and other technologies.
- Shielding output power: According to the required signal shielding output power, customize a spherical shielding indoor space. The blocker should generate an electromagnetic field within a certain range to disable the mobile phones (including PHS-PHS GSM-China Unicom, China Mobile Communications, CDMA-China Telecom) in the space, in order to make the mobile phone unable to make calls or establish connections.
- Signal failure: The blocker should make the data signals sent and received by the mobile phone within a certain range invalid and unusable.
The basic principle of 5G signal jammer is that the mobile phone and the communication base station establish a connection through electromagnetic waves within a certain frequency range, and transmit data information and sound at a specific baud rate and configuration.
The basic principle of mobile phone signal shielding communication is to scan the low-end frequency of the wireless channel at a certain speed. This scanning speed will introduce errors in the received message format data signal, making it impossible for the mobile phone to detect the normal data information sent by the communication base station, resulting in the mobile phone being unable to establish a connection with the base station, resulting in network search failure, poor signal reception, no service and other problems.
The shielding range of the 5G signal jammer depends on its output power, and local natural environmental factors will also affect the range. For example, the indoor data signal shielding is weaker than the outdoor GSM communication base station. In this case, the outdoor shielding range of the GSM data signal is a factor that needs to be considered.
