Full-band signal jammers interfere with mobile phone signals by emitting radio frequency signals at the same frequency as mobile phones. When using a mobile phone, you need to access the base station of a communication operator.

5G full-band signal jammers have become standard test equipment in examinations and are used in various examination situations to prevent candidates from contacting the outside world through wireless signals. However, many people don't understand how it works. This article will introduce in detail how the 5G full-band signal jammer interferes with the signal.

Full-band signal jammers interfere with mobile phone signals by emitting radio frequency signals at the same frequency as mobile phones. When using a mobile phone, you need to access the base station of a communication operator. 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 regular base station signal, thus achieving "interference".

Specifically, the spherical shielding space emitting according to the set frequency will automatically form a shielding magnetic field, disabling the function of the mobile phone to send and receive signals within the specified range. This means that when the full-band signal jammer is in working condition, the mobile phone cannot dial out or dial in, thus achieving the purpose of forced disabling.

6 Bands Signal Jammer

It should be noted that mobile phone signals include 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, 5G jammers need to accurately identify the communication frequency band and develop jammers in the same frequency band to achieve the purpose of completely blocking mobile phone wireless signals.

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. Its principle is based on disabling the function of mobile phones sending and receiving signals within a specified range to achieve the purpose of forced disabling.
