There are multiple ways to block Wi-Fi signals. Here are three common methods introduced by WiFi jammer<\/a> manufacturers:<\/p>\n\n\n\n

1) Brute force attack:<\/h2>\n\n\n\n

This method involves generating interference across the entire frequency band of the target signal (such as the 5G band). By increasing the interference level, the signal-to-noise ratio decreases. When the signal-to-noise ratio is below the minimum threshold required to demodulate the physical layer, the demodulated signal cannot be obtained.<\/p>\n\n\n\n

2) Channel interference:<\/h2>\n\n\n\n

By monitoring the Wi-Fi channel, an interference signal is introduced whenever the router sends a signal. This interference prevents the terminal from successfully detecting the router, effectively blocking it. Alternatively, when the terminal attempts to send data, interference may be introduced, resulting in unsuccessful communication.

3) Exploiting protocol vulnerabilities:<\/h2>\n\n\n\n

In this method, attackers exploit vulnerabilities in the Wi-Fi protocol to disrupt or block signal transmission. By exploiting weaknesses in the protocol, they can interfere with communication between devices and disrupt the normal operation of the Wi-Fi network.<\/p>\n\n\n\n

Wi-Fi blockers usually consist 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 the sweep signal, which is then inverted, modulated to the desired mobile communication frequency band, and amplified by the power amplifier. The voltage regulator controls the power level. The amplified sweep signal is transmitted in the form of radio waves. The chaotic interference caused by the sweep signal disrupts the information signal received by the mobile phone, increasing the ratio of the noise signal to the device threshold. As a result, the mobile phone cannot receive normal data from the base station, resulting in the inability to establish a proper connection. This interference causes the mobile phone to display insufficient signal or service, effectively achieving the desired blocking effect.<\/p>\n\n\n\n
