Basic understanding of signal jamming device

To be able to successfully break a cell phone signal means to be able to block any other type of cell phone communication with a standard signal blocker. To be able to successfully break a cell phone signal means to be able to block any other type of cell phone communication with a standard signal blocker. It is designed to help people solve various problems arising from cell phones, radio signals, and wireless connections. Each type of it is designed for a specific frequency range. Of course, signal jammer design tends more and more to be a comprehensive performance. This means that a jammer can block more and more frequencies. Remember that a wireless device is capable of communicating directly with the specified service network through a base station or tower. These towers divide cities into cells or smaller areas.

The ability to successfully jam a cell phone signal is basically the same as the ability to jam any other type of cellular communication with a standard signal blocker. Note that a wireless device can function by communicating directly with the specified service network through a base station or tower. These towers divide cities into cells or smaller areas.

When a user of a cell phone drives down the street, the signal is relayed like a soccer ball between towers along the way. A cell phone disruptor can successfully transmit over the same radio frequencies used by these wireless devices.

This "white noise" effectively interrupts communication between the base station in the tower and the handset. This is technically referred to as "Denial-of-Service". The cell phone jamming kit was specially developed to cancel (reject) a signal within the radio spectrum to the handsets that are within range of the jamming device.

Jammers are used to protect privacy and are widely used

Nowadays, people are paying more and more attention to the issue of privacy and security, especially the issue of anti-leakage of mobile phones. Mobile phones have become an indispensable communication tool in people's lives, and mobile phone privacy issues cannot be protected. In recent years, there have been many cases of loss of important information and confidential information due to mobile phone signals. The places where mobile phone leaks are generally targeted at various examination rooms, schools, gas stations, churches, courts, libraries, conference rooms, hospitals, prisons, and public security. , Places where the use of mobile phones is prohibited in military powerhouses.

The mobile phone signal jammer is used to quickly detect and evaluate whether the mobile terminal can still work normally under the interference of the jammer in the mobile communication, WIFI and other wireless communication facilities. Covers all frequency ranges of current mobile communications. Stored in the device are the uplink and downlink frequency bands corresponding to all the services of China Mobile, China Unicom, and China Telecom that are currently operating on 2G, 3G, and 4G. The device has five main functions, of which there are three detection and evaluation functions, including: wireless communication shielding detection, rapid detection, and wireless communication signal scanning.

In the information age with the rapid development of the Internet, people pay more and more attention to the demand for anti-eavesdropping devices in their daily lives. In an era when the drawbacks of eavesdropping incidents emerge, people increasingly feel that their privacy is shrinking. Nowadays, various eavesdropping devices of various sizes have appeared on the market. The eavesdroppers will hide the eavesdropping devices in secret-related areas such as offices and conference rooms to achieve the purpose of eavesdropping. Common bugs are tiny cell phone bugs, which use cell phone signals to obtain secrets in conference rooms and discussions. Dojammer recommends that everyone use cell phone signal jammers to ensure the safety of the conference room.

Before you buy, however, you need to be clear about what features you want to signal to the jammer and which frequency bands you want to block so you can go straight to the right catalog and choose exactly the jammer you need.

The signal jammer uses frequency multiplication, frequency division, frequency hopping filtering and other technologies for the uplink and downlink channels of the mobile phone system to analyze the required shielding frequency; customize a spherical shielding space according to the power of the shield, and automatically form a shield within the specified range The magnetic field invalidates the mobile phone in this space. When the jammer is in the working state, it can make the mobile phone's signal receiving and sending function in the specified range invalid, unable to dial out and dial in, so as to achieve the purpose of compulsory prohibition.
