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.

On-board frequency jammer: used for fleet safety and safe travel

How many on-board frequency jammers are needed for fleet safety? This question plagues those who are responsible for transporting their fleet from one place to another. In many countries, the threat of RCIED weapons (also called roadside bombs) is high. frequency jammer is a solution to the threat of roadside bombs; but some knowledge about RCIED failure is required.

Since the late 1970s, we have had experience in countering remote-controlled weapons and introduced a series of bomb attacks. Our current bomb jammer series can withstand the current threat of radio-activated weapons. We install IED jammers in many countries.

At home, we can explain the working principle of our fleet protection solution. Our professional RF technical team members can outline the defensive capabilities of small, medium and large vehicles in the fleet. These people use frequency interference series IED jammers to prevent radio detonators from receiving their commanded knock signals.

What does the security assessment involve? Those who seek our advice either come to our office for consultation, our factory for demonstration, or bring a head of RF technical team to the country to seek electronic warfare defense technology in order to conduct an on-site review of the area. There, we can explain what is involved during RF jamming operations in a fleet scenario, the advantages of our technology, and the limitations of RF interoperability in other radio communication telemetry.

Our extensive knowledge of the subject of RF interference is helpful for those who have little understanding of what is involved in fleet protection operations. We can explain in basic terms how our systems work, how they work, they work well, and what happens when RF interference starts.

Application of military jammers in various fields

The role of drones in interfering with war

The jammer usually causes the drone to perform a vertical controlled landing or return to its starting point-the default action for most drones to lose communication-“to assist in the investigation to determine the pilot,” the company said.

It shows the existence of Mi-8MTPR-1 helicopters in Crimea, equipped with Rychag-AV jamming stations, making these aircraft powerful weapons for electronic warfare operations. One of the main ways Russia adopts these systems is to deal with air defense systems and complexes by reducing the mute of its radio signals and the efficiency of UAV jammers. The results of a survey conducted by Ukraine in March this year showed that in 2016, Russia deployed such helicopters on the territory of SMD and the Western Military District (WMD).

The radar jammer forces the drone to land or return to the drone operator immediately, which means it can protect personnel and infrastructure assets from drone attacks.

The weapons being developed or the arsenals of China, Russia and the United States are undergoing various space arms races. Space weapons include satellite jammers, lasers and high-power microwave gun systems.

Experts say that the biggest threats seen today are non-kinetic threats, such as jamming satellite-based capabilities such as GPS and communications. And the threat is not limited to aerospace countries, because satellite jamming technology is relatively cheap.

North Korea has used ground gps signal jammer in the past to affect military and civilian aircraft and ships. Harrison said there is evidence that insurgents in Afghanistan and Iraq also used interference.

Russian media claimed that the technology developed by the Russian military can neutralize opponents’ aircraft, ships and missiles within a radius of 5,000 kilometers. Vesti News first reported on April 14 that a Russian fighter plane had successfully tested the electronic jamming device on a US warship, the Black Sea destroyer Donald Cook.

Intelligent frequency jammer protects life safety

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.”

What needs do we need GPS jammers to meet?

Since the GPS system has been installed in place, it is of great help to us. Based on the GPS system, we have developed many devices to help us carry out military use and life. But the GPS system also poses a very dangerous threat to us, it can easily reveal our location. Anyone can easily find our location by putting a small GPS device in our car or even pocket. In order to protect ourselves from the danger of illegal tracking, we need GPS jammers. GPS jammer is an anti-GPS electronic device, which can transmit a stronger signal to cover the GPS signal with the same frequency as the GPS signal. Since this signal from the GPS jammer is stronger than the GPS signal, it may cover and hide the GPS signal, so that all GPS devices in a certain area cannot receive the GPS signal and therefore cannot work normally.

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.

Prison installs Jammers to prevent illegal trade

With great concern and for many reasons, I support the legalized control of Cell Phone Jammers for use within correctional institutes.

A cell phone in a prisoner’s possession allows him to contact outside partners in the crime to coordinate evacuation plans, creating life-threatening situations for the guards and the public surrounding the institution. More often, reports from correctional facilities overwhelmingly indicate that hidden cell phones have been used to harass victims of their crimes, or an inmate repeatedly intimidates his victim in an effort to persuade the victim to retract his charges or change his mind. history. the testimony.

Many inmates continue to organize their illicit drug trafficking within the prison walls. A cell phone is an essential way for the inmate to keep the drug organization running and tightly controlled. By communicating with visitors prior to their arrival, prisoners can arrange for a transfer of drugs and drug paraphernalia, allowing them to perpetuate the same illegal habit that brought them into custody. Frequently, the family experiences harassment from their incarcerated parent, demanding bail when the family recognizes that the parent is better served and remains in detention.

A significant concern is a detainee’s ability to contact witnesses prior to an impending hearing, trial or appeal. By matching alibis or correcting conflicts in testimony, an accused can achieve a reduction or a complete dismissal of the charges. The most frightening concern that correctional institutes claim are undetected cell phones used by inmates to warn other inmates ahead of surprise searches that could confiscate cell phones, knives, drugs, syringes and other contraband . This contraband can pose a threat to the lives of correctional officers and medical personnel working in one of the most hostile and dangerous workplaces.

In summary, prisons in accordance with Cellular cell phone jammer is imperative, with a cell phone jammer you can prevent prisoners from using cell phones for illegal transactions or contact with the outside world, endangering the cell phone. public order and cause irreversible injury. Our cell phone jammer is very easy to use. Just turn on the switch, and within 5 seconds, it will enter the state of no network within 40 meters. The phone will display the no service status. Will not affect the use of other equipment.

How can the villa area interfere with the mobile phone signal to prevent theft?

1. The signal of the villa itself is poor, it is far from the signal tower, and the mobile phone cannot receive the signal in the weak signal area.
2. The thick structure of the wall in the villa area blocks the signal.
3. The signal is bad due to interference.

Since the mobile phone receives signals through the propagation of electromagnetic waves, the base station establishes a connection with the mobile phone by transmitting electric waves, so as to achieve the purpose of voice calls. Therefore, the cell phone jammer of electromagnetic waves will have an adverse effect on mobile phones.

It is normal for the mobile phone to display 4G signal and make a call to 3G or 2G signal! It is not caused by cell phone failure or base station failure. The following explains why this phenomenon occurs:
1. 4G has only one data channel (commonly called the Internet channel); 2G ​​and 3G have two channels, data channel and voice channel. So 2G and 3G can surf the Internet and make calls, while 4G can only surf the Internet because it only has a data channel.

2. In the early days of 4G, in order to satisfy the requirement that the mobile phone can make calls when using the 4G network, a solution called CSFB (Circuit Domain Fallback) was developed. Automatically fall back from 4G network to 2G or 3G network before starting to make calls. But this technology has a disadvantage, that is, you cannot access the Internet when making a call, so it is inconvenient for some business users.

3. Now that 4G technology has matured, in order to satisfy mobile phone users with a better experience, VoLTE (High Definition Voice Call) has been developed, which is a technology that can use the 4G network to make calls while also being able to access the Internet. The mobile phone uses the data channel of the 4G network to make calls and surf the Internet, and the call quality is clearer than that of 2G and 3G.

4. Dropping due to handover failure. Network operators use base stations to transmit wireless signals to serve users. The range of base stations is limited. Therefore, there may be many base stations in an area. The combination of all base stations is a network system. Each base station has its own range. If this range is exceeded, the mobile phone must replace the base station to keep the mobile phone in the network at all times.
