With the rapid development of technology, various signals have become more destructive, and the use category has also increased. The scope of application has been extended to many industries, including airports, hospitals, libraries, university examination rooms, etc. If a discreet person uses a signal jammer device, important files can be protected from theft. The WiFi network has become a must for work, but even if we set a password for the WiFi router, someone can easily crack it, and then access your network and use it. In this case, some hackers can steal your data without your knowledge. Therefore, more and more people pay more attention to network security, and some fields have gradually used frequency band jammers that can interfere with various bands.

UAV jammers play an important role in war

In a statement on NBC News, officials of the Ministry of Defense did not confirm whether they had lost any drones due to traffic congestion, but one official said the blockade had an operational impact on Syria ’s military operations. The European Organization for Security and Cooperation, which has been monitoring the Ukrainian conflict, also reported that the drone they used to monitor the front line has been intercepted several times.

Commanders may be more hesitant to use GPS-guided bombs or rockets, especially near friendly forces, if they are worried about getting them on the wrong target due to interference or other forms of electronic warfare. In turn, this may greatly limit the fire support options available to the US military or its allies.

The drone did not appear to be hit by a projectile or laser when it descended (although the evidence to do so would change this analysis). In addition to physical projectiles, there are three known non-dynamic methods of preventing drones: radio frequency jammer, satellite interference, and identity fraud. Due to the interference of the drone jammers, the connection between the drone and its operator will be cut off, which usually causes the drone to descend or return.

Using a drone jammer, the drone will lose its link to satellite navigation, and the drone will usually float in place, land or return home. Through identity theft, the attacker will provide new information to the drone to control its flight.

Drone jammers block radio frequency and signals from satellites

What is a drone jammer gun? The device has certain configurations, is a fully integrated rifle-type countermeasure, and can be used with a variety of UAV models. Although it looks like the most powerful electron gun you have ever seen, it is actually a high-power military jammer device capable of interrupting multiple frequency bands simultaneously.

By blocking radio frequency and signals from positioning satellites, the device interrupted the control functions of commercial drones. Britain is ready for a robot-to-robot war. A new type of anti-drone weapon system developed by Blighter Surveillance Systems called “Anti-Drone Defense System” is a combination of radar, camera and jamming system, all integrated into the device.

This is how it works. First, radar recognizes and tracks flying drones. Then, once the drone is within range of the jammer, the drone jammers device attacks it: three antennas send radio frequency signals to the target drone, trying to isolate it from the original controller. Within seconds, the stuck drone stopped in midair and then fell to the ground.

Among the challenges he faced while working at the signal station, Eng Hosni said: “I have to get all parts from East Asian countries. Gather enough information on how to operate this equipment. I travel to France, Spain, Italy, South Korea and Malaysia To understand how the system works. “He said that the drone jammer has been successfully tested on a drone about 300m high in remote areas. “In the future, I plan to manufacture jammers with screens.”

UAV jammer equipment used in Nanshan Islands, China

China seems to be planning to use electronic attacks designed to damage or control U.S. drones. There are reports that China is attempting to interfere with U.S. drones. In recent years, the United States has at least once been willing to use drone jammers to prevent aircraft from taking off from the United States. The United States carries out surveillance missions in the Nansha Islands.

Murmansk-BN is the world’s most powerful long-range electronic warfare (EW) system developed by KRET, a subsidiary of Rostec Holding. The EW system is designed to disrupt radio communications within a maximum range of more than 3,000 kilometers (1,864 miles). The jammer is specially designed to solve high-frequency communication systems (including global high-frequency communication systems).

Some jammers launched at the beginning of the war, such as GPS jammers in vehicles, reported later updates aimed at overcoming various threat signals. Ryan explained that, for example, the in-vehicle gps interference radiation currently present in thousands of cars in theaters represents a technological capacity increase.

Electronic warfare jammers need to analyze a wide bandwidth with low signal-to-noise ratio (SNR) to detect critical and time-sensitive threats. One way to achieve this is to channelize a wide bandwidth through a filter bank and fast Fourier transform (FFT) to separate the signal of interest from noise and interference sources.

 

Powerful and portable 8-wire WiFi signal jammer

To avoid any noisy noise from your phone, you will need a wifi jammer. This is a new product-CDMA DCS PCS GSM 3G 4G WiFi signal jammer. Do you need a jamming device that can block all mobile phones and WiFi signals at the same time?

8 bands cell phone signal wifi jammer

This 3G / 4G / WiFi / cell phone jammer can definitely help you. This jammer is 4 with the latest design appearance, and has an excellent cooling system inside. Its 8 frequency bands can be used independently. That is, a single frequency band can be adjusted or disabled without affecting the operation of other frequency bands. Because it is equipped with a car charger and adapter, it can be used directly on the car, which is very convenient for users who want to use it while driving. According to the signal capacity of the application area, its interference range can reach 20 meters.

Use a WiFi jammer to block hidden cameras

It is often misunderstood that “voyeurism” is not a crime. The crime is to show clothes, nudes, skirts, etc. If evidence of sexual harassment, power harassment or domestic violence is left, it is not a crime.
Otherwise, all shops that sell hidden cameras will contribute to this crime. Since you do n’t know what hidden camera to buy, you can only link to a mail order store.

The Aichi County Police announced a security store robbery that occurred on the 15th day of the morning. The image security surveillance camera of the suspect fled from behind the suspect and was captured. The criminal is about 160 cm tall and thin. In the published image, you can see the characteristics of the black headscarf, covering the face, black leather jacket and blue jeans. When committing a crime, the suspect pushed a kitchen knife or something to the clerk, and robbed 55,000 yen in cash and escaped. Another feature besides clothes is that he is a bend.

Hino’s true intentions are reflected! The first protagonist of Yano Makoto’s TV series “Yorozuya Johnny” will be broadcast. The original episode “Yorozuya Johnny” will be aired in two episodes / animations of CS Broadcasting Fuji TV on Friday, November 20th. This work is a human observation drama, using Johnny’s miniature night vision camera to inspire human desire to watch the invisible human real intentions. The hero Johnny with special skills can install hidden cameras anywhere and sneak into various places under the command of the boss. Whenever he starts to study this ability, he is always immersed in a miniature camera and becomes a human observer. Use a wifi jammer to block the WiFi frequency band and to some extent invalidate the camera.

At the 2015 IT Week in Japan held at Makuhari International Exhibition Center as of the 30th, National Defense Labor Aviation demonstrated the DEFENDER-X security surveillance system. “DEFENDER-X” is a system that automatically analyzes a person’s mental state and detects suspicious people from the video of a surveillance clock camera, the purpose of which is to prevent crime. According to the correlation between the body’s subconscious vibration and human emotions, the technology used can be obtained by analyzing the psychological state of the object.

Signal jammers prevent exam cheating and wire fraud

Cheating seems to occur at the same time as the examination system is started, and the rapid development of electronic communication means seems to be diversifying examination cheating means. On the other hand, we have taken measures such as prohibiting the use of mobile phones, considering the use of metal detectors and checking the names of people who use the toilet. Among them, there is a product that attracts attention. It is a signal shielding device that blocks radio waves from mobile phones. This product is a device that has a mechanism to block radio waves from mobile phones by emitting special radio waves.

In fact, signal jammers are not only suitable for university entrance exams, but also for qualification exams, high school entrance exams, national exams, etc. This means that cheating using mobile phones is already very common and difficult to control, and it is the most effective way to install signal jammer and temporarily “out of range” test centers. Equipment installation requires a radio station license.

By transmitting weak radio waves having the same frequency as radio waves broadcasting information, the display of the mobile terminal becomes “service interruption”, and communication is suppressed. The device will be installed around the bank. We will begin to restrict the use of mobile phones in ATM corners. This is an initiative of financial institutions to work together to prevent crimes such as wire fraud. Several financial institutions will jointly install equipment in ATM corners. We use it as a transfer fraud measure.

Signal jammer can help prevent cell phone use

Definition of interference equipment: A signal jammer is a device that emits radio waves in the same frequency band as mobile phones and other devices. After installing the machine, the phone will not be in the service range. You cannot make or receive calls. During this time, with the rapid popularity of smartphones and other devices, I felt uncomfortable with cell phone ringtones in cinemas, cafes, museums and concert halls.

There are many situations that bother other people. There are bad behaviors, such as cheating on a mobile phone at the test site, creating unfair results. In addition, sensitive information may leak in sensitive locations such as military bases and government agencies, and hospitals also need to provide patients with a tranquil environment. Using a signal jammer can prevent ringing and talking on the phone, prevent cheating, prevent the leakage of private and confidential information, and prevent radio noise.

The radio waves from the base station are blocked, so that the mobile phone and the base station cannot be connected normally, and the terminal cannot be used. The phone is disabled. This means that you can make and receive calls temporarily.Cut-off signal: Compatible with GPS / 3G / 4G / CDMA / GSM / DCS / PHS / Wi-Fi.
