In the field of mobile communications, a WiFi jammer is a device that prevents signal transmission by generating interference. The jammer sends signals in the frequency range used by the handset, and mobile phone users may lose signals in the jammer range. Jammer is usually undetectable, and users may experience slight shocks, such as poor signal reception. Interfering devices can be used anywhere, but are often used in situations where mobile phone use is disruptive, such as in libraries and restaurants.
How to use wifi jammer? The phone must communicate with the network provider through the base station or base station. By sending radio waves on the phone's frequency, the signal blocker launches a denial of service (DoS) attack, resulting in loss of base station traffic. A cellphone jammer is a device that normally blocks signal transmission or reception by generating some form of interference, which interferes with the frequency range used by the cellphone. As a result, mobile phone users will lose signal or signal quality.
Why use a WiFi signal blocker? Cell phones are both good and malicious. Police and the military often use them to limit or interfere with communications when hostage-taking, bomb threats or military operations. Personal portable jammers can place the main unit nearby (up to 60-80 feet) to prevent others from using the phone. Similar devices have also been manufactured to protect signals from environments where mobile activities may be undesirable, such as theaters, churches and operating rooms. In short, a jammer is essentially a signal protection device that sends synchronous radio waves in the same frequency range of a device that needs to be blurred, thereby preventing the device from sending data in the selected area.
