What is the role of wifi jammers?

In today’s world, Wi-Fi networks have become an integral part of our lives, both in public places and at home. Computers rely on Internet access, and many smartphone functions also rely on Wi-Fi. However, there are situations where you may not want to be interfered with by Wi-Fi signals. In this case, a WiFi jammer can solve your problem. Please visit JAMMERSIGNAL to learn more about what Wi-Fi jammers are and what they do.

To understand WiFi jammers, we need to know the frequency range used by WiFi signal transmission devices, which is usually between 2400 and 2500MHz. Mobile phones and computers receive these signals to establish communication. Based on this working principle, a Wi-Fi jammer usually consists of a power supply, an electronic scanning control unit, a segmented RF module unit, an amplifier unit, and a transmitting antenna unit. The signal generator generates a swept frequency signal, which is modulated by an oscillator to match the mobile communication working frequency band. The power amplifier amplifies the sweep signal, the voltage regulator controls the power, and the amplified sweep signal is transmitted in the form of radio waves, which interferes with the received Wi-Fi device information signal, making it impossible for the mobile phone to receive the information sent by the Wi-Fi device normally, unable to establish a normal connection, and causing the mobile phone to be unable to search for network signals and access the service system, thereby achieving the expected shielding effect.

The interference power of any signal jammer is fixed, and the range of the unprotected space depends on the path attenuation and the signal strength of the receiving base station. To interfere with the Wi-Fi network signal, the signal field of the jammer must be greater than the signal strength of the mobile device in the interference area. The closer the jammer is to the device transmitter, the better the interference effect, and the farther the distance, the worse the interference effect.

It should be noted that at a certain transmission power, the interference range is determined by the field strength of the affected area. No matter how powerful the cell phone jammer is, as long as the transmission power remains unchanged, increasing the power of the interference signal will reduce its interference ability.

The development of wireless networks for smartphones has greatly accelerated technological progress. Mobile phones have become an indispensable function for mobile communications, mobile Internet access, etc., which has greatly affected people’s lives. However, this convenience also brings challenges, especially in home networks where children may be addicted to the Internet, mainly accessed through Wi-Fi. Therefore, many families choose to install mobile Wi-Fi screen shielding devices to control children’s online time.

Although wireless networks provide a convenient way to access the Internet, the problems they may bring should not be ignored. These problems are not limited to network accessibility, but also network security. In order to maintain a safe network environment, many institutions have begun to install Wi-Fi filters to protect network security and prevent excessive network use. Such devices are widely used around the world, and common examples include schools, prisons, libraries, reading rooms, and gas stations.
