How does the 5G full-band mobile phone jammer interfere with the signal?
The 5G full-band mobile phone jammer has become the standard test equipment in the exam and is used in various exam occasions to prevent candidates from communicating with the outside world through wireless signals. However, many people don't understand how it works. This article will detail how the 5G full-band signal jammer interferes with the signal.
The full-band mobile phone jammer interferes with mobile phone signals by emitting radio frequency signals of the same frequency as mobile phones. When using a mobile phone, it is necessary to access the base station of the communication operator, and mobile phones of different standards use different frequencies. The full-band signal jammer emits the same frequency band as the mobile phone, making it impossible for the mobile phone to distinguish which signal is a conventional base station signal, thereby achieving "interference".
Specifically, the spherical shielding space emitted according to the set frequency will automatically form a shielding magnetic field, and the function of sending and receiving signals of mobile phones will be disabled within the specified range. This makes it impossible for the mobile phone to dial out or dial in when the full-band signal jammer is in working condition, thereby achieving the purpose of forcible disabling.
It should be noted that the mobile phone signal includes not only mobile data, but also Bluetooth and WiFi signals. Different wireless communication technologies work in different frequency bands. For example, 2G mainly works in the 900-1700MHz frequency band, while Bluetooth and WiFi work in the 2.4GHz frequency band. Therefore, the 5G full-band signal jammer needs to accurately identify the communication frequency band and develop a jammer with the same frequency band in order to completely shield the mobile phone wireless signal.
To sum up, the 5G full-band signal jammer is a device that interferes with wireless signals by emitting radio frequency signals of the same frequency as mobile phones.
