Remote control high-power wifi jammer is widely used in prisons, protection, surveillance and other fields. If you are looking for a powerful and effective office interference device, you can stop here. Just put the device in the shopping cart, if you use this interference in the office, you can easily block the cell phone signal in the office. Since you have locked the cell phone signal in the entire area, your employees will not have the right to disclose more information.

The first use of electronic jamming countermeasures can be traced back to World War II. Radar-controlled artillery shot down many Allied aircraft. These systems use radar signals to block and track air targets and direct air defense firepower. When conducting critical joint operations, resistance forces place RF interference near these weapons. Video footage from news movies shows how the shells spun suddenly and fired randomly due to interference. The barrel designers were too arrogant and did not consider the possibility of interference, so they never used a "manual override" switch.

The operating frequency and signal strength of the GPS jammer are greater than the expected signal of the receiver. Therefore, if the jammer has enough power and a wide enough 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.

Military officials declined to say whether GPS was in battle. But solutions have been developed to overcome this problem. First, the Air Force and Navy have electronic warfare aircraft that were modified in the 1990s to detect GPS jams, said James Hasik, co-author of "Precision Revolution: GPS and the Future of Air Warfare." Hasik added that military officials have also updated Raytheon’s "hazard" missiles so that they can identify GPS jamming launches.

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 is the case, because interference and deception will offset the equipment used by the end user, cut IT pathways and introduce false data. In various systems. For cyber fighters, detecting and preventing GPS blocking and phishing may be a shortcut.
