Question: Are portable radio frequency jammers as effective as bomb jammers?

Answer: It depends on several factors. Many manufacturers claim how their portable radio frequency jammers will use their interference methods and the interference methods they use. Although we did not explain in detail how portable radio frequency jammers such as portable jammers participate in countering improvised explosive devices to the public, we can disclose open source information.

These factors are the interference methods used by portable radio frequency jammers; the spatial factors of the radio transmitter related to the radio receiver and the characteristics of the knock signal related to the specific frequency used by the RCIED.

The intelligent frequency jammer is a new generation of multifunctional jamming system, which can significantly enhance the protection of vehicles against radio-controlled improvised explosive devices (RCIED).

The new mobile frequency jammer combines intelligent jamming capabilities with signal intelligence (also known as electronic support measures-ESM) to understand threats in detail, thereby significantly improving mission planning and force protection.

The multifunctional frequency jammer analyzes the signal spectrum around the vehicle, so it can block radio signals used to trigger roadside bombs in a targeted manner, instead of suppressing noise through a wide spectrum, preventing friendly communications or operating on specific frequency bands, leaving This is a fragile gap that could be exploited by the insurgents.

The multi-function jammer adopts a new ultra-fast intelligent response jamming technology, which can greatly improve the protection level. The system detects and classifies radio signals used to ignite roadside bombs. Then it transmits interference signals in real time, which are completely suitable for the harsh frequency band. Thanks to the new digital receiver and signal processing technology, it is possible to achieve response times far below milliseconds.

The new jammer also uses an extension to provide signal intelligence in combat space images-this task could only be completed by relatively complex systems that were difficult to deploy and consume a lot of energy. The new instrument obtains the “electronic warfare” of the radio communication threat situation in a shorter time. This new feature can help users gain power protection and intelligence vital to further operational planning.

“The lessons learned in recent conflicts prove that the enemy often changes the type of radio transmission used to trigger signals in asymmetric scenarios,” explained the head of the Sensors and Electronic Warfare Unit. “Therefore, continuous analysis of threats and the resulting adjustments to countermeasures are indispensable. Multifunctional frequency jammers are needed to accomplish these two tasks faster and easier.”

GPS jammers are becoming more and more popular

As GPS systems become more and more popular, GPS signal jammers have become necessary for us. You may want to know what GPS jammers are and what potential applications they have. In order to explain the GPS jammer, we first need to know how the GPS system works. Global Positioning System—GPS for short, is a system used by many people, companies and military for navigation purposes. The GPS system uses a series of satellites that emit radio signals. Such signals reach the electronic GPS receiver to determine the position by triangulating the shape. GPS can be used for personal portable electronic devices, vehicle navigation and positioning systems, and can also be used for small GPS tracking devices. The position of a person can be found by triangulation, which is a method of measuring three separate points to calculate the position. In the GPS system of the vehicle, the position of the car is measured by three satellites orbiting the earth. GPS can accurately transmit location information to the receiver through triangulation.

Let us now look at GPS signals, which are radio signals occupying specific frequencies. GPS actually has two main frequencies, one is for public and non-military use, and the other is only for the US military. Since GPS is nothing more than weak radio waves, although technical equipment and expertise are required for this purpose, GPS jammers can be used to block or distort these waves.

GPS jammers were originally created by the government for military organizations and spy agencies. Some themes can be combined with cell phone jammers (also called cell phone jammers and wifi jammers). Uses include messing up the enemy at exact locations, or making enemy GPS guided missiles or bombs fall in these places.

Recently, civilians have sought these devices to ensure their privacy in a world increasingly tracked by GPS. However, most civilians do not have the technical ability to create their own devices because it is much more complicated than blocking radio signals through basic radio interference.

In the future, many companies’ anti-drones will become the focus of development

Countries all over the world have accelerated the pace of development in the field of drones. Many countries and companies regard it as the most attractive piece of cake in the military industry market. Under the impetus of this cake, the development of drones will naturally mean buying drones. Become a trend. However, spears and shields are always relative terms. With the booming development of drones, some countries have also invested in research on how to counter drones. Many companies in our country are naturally not far behind, such as Beijing Shenzhou. Mingda’s anti-UAV technology is favored by many customers at home and abroad due to its excellent performance and quality. Because they have successfully solved the existing deadly threats from drones by using its anti-drone technology.

According to the official website of Beijing Shenzhou Mingda, the total sales of their company’s drone jammer sales are expected to exceed about 200 million US dollars. At the same time, the market will increase to about 1 billion US dollars in about 2-3 years. The total amount of these transactions in the global arms market is not high, but it can be regarded as the performance of a major breakthrough in the field of anti-UAV by Beijing Shenzhou Mingda. The outstanding performance of Beijing Shenzhou Mingda’s anti-UAV technology is due to a series of anti-UAV control products developed by the company in recent years. The company launched the DZ01 bag single-soldier portable low-altitude UAV control system in early 2017. , Launched the third-generation product DZ01 PRO gun-type single-soldier portable low-altitude UAV control system in May 2017, and officially launched the fourth-generation portable four-channel strike gun DZ03 PRO in 2019. The latest generation strike gun has a higher single-channel power , The interference distance is longer than the previous two generations of products (the interference distance is more than 2.5 kilometers), and the current advanced interference technology is adopted to deal with the interference of the flight control signal and the navigation signal to achieve a faster and more accurate interference effect. Really achieve long interference distance, low radiation, lightness, and simple use. Individual soldiers are portable and can achieve non-destructive precision strikes against drones from the sky!

New anti-drone guns impose order in the sky

In recent years, drones have become a rare pastime for amateurs. Now drones are everywhere, from people taking selfies, to commercial photography, to search and rescue missions.

Because of its ubiquity, accidents started to happen. The sky has become a drone infestation, and laws must be enacted to maintain order in the air, mainly in cities and airports. Due to their number and ability to carry all kinds of luggage, they have also become a serious threat to security expert review.

As mentioned earlier, it is not uncommon for drones to almost collide with aircraft, and drones equipped with cameras (or worse, explosives) may pose unique threats to the safety of the ground and facilities. However, in most cases, there are not many safe methods to deal with them.

Now, a new device that looks like a weapon in science fiction uses electromagnetic signals to knock drones out of the air quickly and safely.

drone jammer gun high power

Drone jammer guns are described as providing “safety countermeasures against various drone models.” It allows controlled management of UAV payloads (such as explosives) without causing damage to common UAV models or the surrounding environment. “This anti-drone device weighs about 8 kilograms and has an effective range of up to 1 km. It can be used on a rechargeable lithium-ion battery. As far as design is concerned, it will not be used by Stormtroopers in Star Wars movies.

It is very simple: you point the gun at the drone and pull the trigger. Transmit a series of electromagnetic signals and block the connection between the drone and its pilot. It uses radio frequencies to stop the drone from transmitting video and block the drone’s signal, forcing it to return to the launch point or land on the spot. “If the drone’s response is to go back to the beginning, this provides an opportunity to track it back to the operator.

Of course, there are other high-end technologies that can also attack aerial drones. It is an automatic defense strike system for drones.

The Union Secretary of the Interior recently held a meeting with representatives of the Indian Air Force, Ministry of Civil Aviation, Central Industrial Security Force (CISF) and others stakeholders to discuss this issue.

“The draft drone policy is in its final stages. It focuses on regulating the use of unmanned aircraft and similar flying objects at low altitude. The policy itself is expected to be released into the public domain this time. this month to consult with stakeholders. ” the official Say.

The official said that if the National Security Guard (NSG) and the CISF consider him a “thug,” they may have the right to shoot down any low-flying object that “makes mistakes.”
Both forces will have defense mechanisms such as electromagnetic systems, which will have built-in radars, radio frequency wave jammers and detectors.

The policy will have a preventive function to ensure that terrorist organizations or other anti-national elements will not abuse any low-flying object.

The policy was formulated after several drones were discovered at airports and border areas, which hampered air traffic and caused security concerns.

“There is a need to supervise drones to prevent their abuse in sensitive areas like airports. This policy will stipulate how to control thieves who operate drones.” Another official said.

The policy will have two aspects of enabling functions: granting permission to use drones at international borders and enabling national protection of important facilities and disaster relief operations.

Can 4G Cell Phone Jammers Really Protect Your Personal Information?

The development of communication systems has slowly evolved from slow network connections to fast network coverage at first. This development is driven by the need for a more reliable, efficient, and congestion-free network that can transfer large amounts of data. The information and communication technology field is not idle. It is always in the R & D program and ensures that it is properly placed in the world of dynamic technology. The jammer shop company wants to share news about 5G networks. South China, an Asian giant of technology discovery, is heading towards the introduction of a fifth-generation network planned as a universal communications technology after 2020.

5G networks are 1000 times faster than the 4G networks currently in use. This is an invention and progress that every country wants to associate with. The Seoul government has promised to support this project and will raise $ 1.5 billion to ensure that the program is implemented effectively.

It has been reported that the entire movie can be downloaded in less than a second using such a network. In fact, it’s unbelievable for other countries struggling to connect their rural environment to 3G networks. Advances in this technology are costly, and citizens, governments, and governments need to upgrade their communications devices to cope with this rapid pace. It’s not surprising that the government is spending such money to ensure the success of American communications technology.

Just as South China developed 2G networks in the 1990s and 3G in 2000, developing 5G networks has many advantages, and the US economy is speculated. I will. The country has 82.7% more Internet users than the United States. This percentage is expected to reach saturation soon, making China a country where anyone can access and use the Internet.

With the growing number of Internet users and the growing demand for more data traffic channels, this upgrade is appealing to many investors interested in communications technology. Huawei is some of the companies that have registered their willingness to use 5G networks. The Beijing government plans to deploy the network from 2017 and will be fully deployed by 2020. If you’re still unsure, you can track your location on a 5G network.

5G networks can connect billions of connected devices. This is a further development of current 4G on video. Using 5G networks reduces the chance of network outages and improves coverage. Good coverage is associated with low power consumption, resulting in lower battery consumption and significantly lower energy consumption.

China’s information and communication technology is a world leader. Genuine news media such as CNN and Miller report increasing use of devices with portable technology over American communications networks. Therefore, in China, 5G does not disrupt the network, so citizens can be encouraged to buy advanced electrical equipment that can be controlled from anywhere. However, keep in mind that all mobile devices and networks can be hacked. Therefore, we recommend using cell phone jammer to protect your personal information.

U.S. Army tests could not stop the new GPS last fall

Last fall, after Russia was suspected of jamming GPS signals in Europe and elsewhere, the U.S. Army will test an anti-jamming GPS to solve the defense breakthrough problem.

GPS jammer can also pose a major threat to the United States and allied forces, and everything from troop movement to guided missile and UAV guidance depends on the system. Last fall, the United States and NATO allies launched a large-scale joint exercise called Trident Juncture in Norway to test the joint preparations and training of a large multinational alliance. During the exercise, the military noticed that GPS signals interfered with signals attributed to Russia by Finnish and Norwegian officials. In April 2018, US officials stated that the Russian military had blocked the GPS system of UAVs used in Syria.

Members of the German Second Cavalry Regiment will be equipped in the fall. According to reports, the Army is considering developing a new generation of inertial navigation system that can be used as a backup system.

At the C4ISERnet conference in Arlington last week, Colonel Nickolas Kioutas, project manager for Army procurement developer Positioning, Navigation and Timing (PNT), said that it’s important to deliver equipment to troops quickly, and the Army is working hard to roll out the Equipment used in the iterative process. Breaking the defense points out that by putting the system in the hands of units like the Second Cavalry, the Army can quickly evaluate technology and make improvements if necessary-without spending years developing and testing equipment that turns out to be the wrong one.

Mobile phone signal interference in urban village rental houses helps to rest

The shadow behind the splendor of every big city is the village in the city. For example, there are many large and small urban villages in Guangzhou. Shipai Village is the largest and oldest among them. People’s first impression of urban villages is crowded, noisy, and a lot of garbage. The alleys are densely packed, with wires and spider webs crisscrossing overhead.

Because the village is too dense and surrounded by high-rise buildings, the village in the city has a weak signal or even no signal at all in addition to being dark and humid. However, most of the people living in urban villages are fresh graduates or young people who have come to the city to struggle. The lack of mobile phone signal is very difficult for young people to accept. The lack of mobile phone signal not only affects their social activities, but also affects their job prospects. Therefore, many renters hold a mobile phone when they look at the house, and when they come in, if there is no signal in the house, they immediately shook their heads and left.

So, how to solve the problem of bad mobile phone signal? The cell phone jammer is a wireless communication device, which is different from general electrical installations. It may seem simple to install such wireless communication devices, but there are many knowledges in it:

1. First of all, before installing the equipment, fully test the signal and electromagnetic environment to determine the type of equipment, wire and antenna to be selected. To complete this work, it is difficult to do without relevant instruments and professional knowledge. Many people did not understand the reason and bought the equipment and materials at will, but the results were ineffective, and money was wasted.

2. Secondly, during the installation process, there are certain tricks in the design, layout and connection of the circuit. The same equipment and materials, let professional and technical personnel and ordinary electricians to install, the effect will be different, let alone ordinary people.

3. Once the equipment is installed, it needs to be debugged carefully. Equipment debugging is a complex and professional work, which is often far from perfect, and it is difficult for it to be a professional.

4. Finally, the current mobile phone signal amplifiers on the market are mixed, and most of the products are not guaranteed in quality. Many machines only have amplifier circuits, but there are no quality control and anti-interference control circuits. It felt good at first, but it didn’t take long to get worse. Such an amplifier is not only easily affected by environmental changes, but also has a great impact on the surrounding electromagnetic environment, and even interferes with the normal operation of the base station.

At present, many rental houses in urban villages have installed cell phone signal amplifiers, but most of the owners buy them and install them by themselves. In addition, because of the desire to be cheap, the quality of the equipment purchased is very poor, so the signal effect is not good. How many companies have made the outdoor signal environment more and more complicated.
