Mobile phone jammers work on the same principle as jammers that prevent radio communications

When the mobile phone blocking program is active, most mobile phones will not display the network signal, and when the mobile phone gsm blocking program is closed, the phone will be activated. Mobile phones use unique frequencies for talking and listening. Most cell phone jammers will block either of these two frequencies, thereby indirectly providing the prevention of both. Mobile phone jammers work on the same principle as jammers that prevent radio communications. They work by interrupting the frequency from the mobile station to the base station or from the base station to the mobile phone. China uses GPS to block the US military. Traffic jams and GPS spoofing are often classified by US officials as “electronic warfare” rather than “cyber warfare.” We don’t understand why this happens, because interference and deception will offset the equipment used by the end user, cut off IT channels and introduce false data. In various systems. For cyber fighters, detecting and preventing GPS blocking and phishing may be a shortcut.

The operating frequency and signal strength of the gps jammer are higher than the expected signal of the receiver. Therefore, if the jammer has enough power and a sufficiently wide signal spectrum, it may block all receivers on one pedestal. Another method is to jam a copy of the expected signal and trick the receiver into receiving the interference signal instead of the expected signal. NBC News quoted four sources inside the Pentagon as reporting that the broadcast of GPS signals began a few weeks ago. It started shortly after the Syrian regime allegedly carried out a chemical attack in the Ghouta area controlled by the rebels. According to reports, the Russian military is worried that the US military will retaliate for the use of chemical weapons and drones to prevent the US military from collecting intelligence.

According to a new intelligence report, weapons capable of destroying or destroying U.S. military and commercial satellites will reach initial combat capabilities within the next few years. Now, you can use any smartphone or PC to control the jammer, just connect to the ESP8266 module to search for WiFi networks from your phone or PC or MAC and connect to AndroidAP. The password is killwifi. You can change this SSID and password from the uploaded code. After connecting, you can use this ANDROID APP to control this wifi broadcast. Although NBC News claims that it is affecting small drones, not MQ-9 Reaper or large drones, it is not clear which drones are being affected. This means that the jammers are effective, but have a short operating range, and larger drones can fly above them. On the other hand, as the maritime supervisor pointed out, large drones also have backup inertial navigation systems and do not rely entirely on GPS. Paper jams can affect smaller tactical drones, such as RQ-7 Shadow or ScanEagle.
