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.

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.

Overflying drones brings security risks anti-drone systems become the main force

The development of unmanned aerial vehicle technology has threatened the safety of many fields, especially some indiscriminate flying drones, which has brought security risks to important places such as airports. In order to be able to effectively prevent the occurrence of dangers and to effectively solve the interference of drones, Beijing Shenzhou Mingda Company has made great efforts to develop anti-UAV defense systems to protect safety and privacy in various fields. As an expert in anti-UAV systems, Beijing Shenzhou Mingda has developed various types of anti-UAV products, which are applied in various fields and scopes, and become the main force in combating unmanned aerial vehicles.

It is understood that the Greatjammer drone jammer mainly uses signal infection technology. Through advanced interference technology, the signal between the drone and the operator is blocked, and the data transmission is cut off to ensure that information is not leaked. Not only that, the Beijing Shenzhou Mingda counter-UAV system can also detect commercial small UAVs, and use signal interference technology to locate the invading UAV in mid-air, and at the same time, change the UAV’s route and target. Drive them out of defensive airspace, or prevent other UAVs from entering the airspace over areas that are prevented and controlled by counter UAV systems. The most important thing is that Beijing Shenzhou Mingda has continuously upgraded its drone technology during its development process. No matter what kind of drone it is, it will be detected by the Beijing Shenzhou Mingda UAV countermeasure system and be effective. Interference, there will never be any slipping fish. As the industry’s leading manufacturer of UAV countermeasures, Beijing Shenzhou Mingda has leading anti-UAV technology, guaranteed product quality and good interference countermeasures. It is a wise choice for all walks of life to counter UAVs.

How to prevent eavesdropping in the car?

The ever-changing technology also makes it easier to expose people’s privacy to the public’s vision. Recently, a small gsm eavesdropping on the market is very popular. It is understood that many buyers install this type of eavesdropping device in the car. Many people also responded to our colleagues that they were afraid that their private conversations would be eavesdropped. This kind of eavesdropping equipment can be installed in a very hidden place and is not easy to be found. Even many professional anti-eavesdropping equipment cannot be detected. What is it? The reason?

It is understood that this gsm bug is only the size of a coin. It can be placed in the car, or it can be attached to a certain place on the car using a magnetic device. What is more, it can be placed in a place that is difficult for people to detect (such as the instrument In the built-in electrical equipment), the driver’s conversation information can be recorded unconsciously. Of course, the eavesdropper may also receive a car battery or a large-capacity battery for continuous GSM tracker. On the other hand, this makes the threat more persistent and keeps the privacy of the eavesdropped being stolen. This GSM bug can be placed in a hidden place in the office or at home, such as under the desk or built-in in household electronic devices such as alarm clocks, TVs, and chargers. It is very hidden. The power supply under the table may be cut off and may be unintentionally discovered, but it is not only difficult to be detected when it is built into an electrical appliance, but it can also be directly used for indefinite long-term work. Illegal tracking of vehicles, eavesdropping of conversations in vehicles, and eavesdropping of private households are illegal acts and a great threat to personal privacy, and should be paid attention to.

Why is this kind of eavesdropper so difficult to detect? Because it is an analog mobile phone signal, it is mixed in many mobile phone signals, and it is not easy to detect. Even if some professional detection equipment is not operated by someone who is very familiar with wireless signals, it may be No results are found. When the eavesdropper dials the phone card number in the eavesdropper in a remote place, the eavesdropper starts to work, and the surrounding sounds are transmitted to the eavesdropper through the mobile phone signal. Tracking and positioning. It is always threatening people’s normal work and life.

For such a very concealed eavesdropping device, should it be located and swept away? The following is a practical anti-eavesdropping GSM jammer recommended by the security experts of Shenzhou Mingda, because the working principle of gsm eavesdropping device is similar to that of mobile phones, so The mobile phone detector can well detect the source of such gsm bugs, so as to find the eavesdropping equipment, remove hidden dangers, and completely eliminate the threat of eavesdropping and tracking. It can find hidden mobile phones in the environment (turn on or off, even without batteries). It is a short-range mobile phone scanner, which is different from traditional metal detectors: it can detect the common material of all mobile phones, not just for metal, which can reduce false alarms for other metal materials, such as watches , Keys, coins, belt buckles, etc. This anti-eavesdropping detector is very easy to use. It can quickly complete environmental security detection and find hidden mobile phones in time (even if they are covered by metal or packages can be detected). The device is easy to operate, with LCD interface display, and 9V battery power supply, which is convenient to carry. It can help car owners to detect eavesdropping on their cars.

Why do schools use mobile phone jammers?

We used to be students in the school. We know that the school has a box similar to the size of a speaker. This is what we call a mobile phone jammer. Why do schools install mobile phone jammers? The answer is obvious: mobile phone signal jammers will block mobile phone signals and prevent mobile phone use.

The main reason for the installation of mobile phone shielding devices in school equipment is the increase in the number of students using mobile phones. Almost every student has a smartphone. They cannot control the use of mobile phones well, whether it is in class or during class time. Part of the time is spent on mobile phones. What do they use mobile phones for? Many teachers find that students now mainly use mobile phones to play popular games. Games have become an important part of their lives. Many topics they talk about in daily life are also related to games.

Students use mobile phones in many ways, the main purposes are different, but almost all have nothing to do with learning. The way of learning is very bad. The influence of mobile phones occupies most of their time. They spend very little time on study and rest, which not only affects their studies, but is detrimental to their bodies and growth. In addition, the school knows that the use of mobile phones by students will greatly affect the various ranking factors of the school and the construction of school style, which has a very unfavorable effect on the development of the school.

There are several reasons for the installation of mobile jammers in schools, but the main purpose is to block students’ mobile phone signals and prohibit students from using mobile phones in schools.

First of all, the school uses mobile phone jammers for the academic considerations of students. Students are the backbone of the country’s future, and the country’s development cannot be separated from generations of students. Therefore, in the student days, mobile phones cannot be destroyed by a generation of talents. The national key qualification examination adopts mobile phone jammer.

Secondly, the use of mobile phones by students not only affects their own learning, but also affects their health. They also affected the school’s ethos and its development.

Third, schools also show a responsible attitude. Schools are places to learn, to educate and educate people, and schools to cultivate talents. The vast majority of parents send their children to school so that their children can learn more and become people who will contribute to the country and society in the future. Using a mobile phone signal blocker can prevent students from using mobile phones and spend more time studying and resting so that they can grow up healthily.

Finally, mobile phone jammers used in schools are mainly purchased online, and school staff will select interference devices suitable for installation in the classroom according to the scope of use of the school. As you can see, the shielding equipment used in ordinary schools is waterproof. It can be used not only in schools, but also in prisons or theaters, cinemas, etc. Mainly designed for larger situations, with powerful power, interference radius of up to 100 meters, all mobile phones can interfere with frequency, can also block wireless WiFi and Bluetooth signals, built-in antenna, and easy to use, just turn on the power, high temperature , Can work for a long time, is an important device that prohibits the use of mobile phones.

US military develops new electronic jammer

An overview of US federal government policy on activities where jammers can cause loss of GPS signal:
Sometimes the US federal government has to perform GPS tests, training activities, and exercises involving jamming of GPS receivers. These events are the subject of long-term coordination by the Federal Aviation Administration (FAA), United States Coast Guard (USCG), Department of Defense (DoD) and other government agencies.
The Army Threat System Management Office (TSMO) team visited the National Training Center on December 2 to demonstrate the newly developed electronic jammer at the Redstone East Arsenal office in Alabama.

Curtis Leslie, TSMO electronics engineer, said the team briefly introduced senior leaders at the National Training Center to how to program a small purchase direct injection jammer based on prompts to simulate radio signals used for detection and electronic communication in battlefield training scenarios. interference.

Leslie said, “We can put them on Hummers, Hummers and other 5 ton tactical vehicles.” “Our injection jammers can be used to replace outside interference.”

The interference box is installed between the antenna and the radio transceiver. When prompted by a simple line-of-sight signal sent remotely by the observer-controller-trainer, it can be programmed to digitally generate various interference signals.

Leslie said typical jamming transmitters broadcast live on “public” radio waves require approval from the military, Federal Communications Commission, or Federal Aviation Administration, which generally limits interference to late nights and early in the morning. He said that while the concept of jammer injection is not new, recent technological advancements have made wifi jammer smaller and require less power, making them ideal for military training centers, as in training centers, the radio spectrum can be very crowded and problematic.
The National Training Center demonstration is part of the Army’s space training strategy, which will provide cutting-edge technology developed by TSMO for the combatant training community.

Devices that can detect jammers are used by law enforcement

Humphreys is a University of Texas expert and is frequently consulted by law enforcement agencies and other government security experts. He said there may be other jammer incidents that have not been made public.
He said: “When I was questioned by the FBI, they often mentioned incidents of frequency jammer and even deception … but of course they did not reveal the details to me.”

Humphreys demonstrated how to use deception to use GPS for navigation to control a vehicle. In June 2012, he and several graduate students demonstrated the technology to Department of Homeland Security officials by commanding civilian drones; The following year, they had a larger run – a 213-foot superyacht – and tricked its GPS navigation system, causing the ship hundreds of meters to deviate from its course in the Mediterranean without issuing any vessel warnings.

Humphreys said these demonstrations require considerable effort and expense, and it is estimated that it took five years to develop “devices capable of simulating and then overwhelming real GPS signals.”

But last year, when Chinese technical experts showed the Defcon Hacking Conference how to use a $ 300 software radio to spoof a GPS, the situation changed dramatically.

Humphries said, “Now I have the ability to download what’s available online to a commercial RF card and build your own scooter.” “For those with little experience of RF work, it will only take a few hours.”

Humphries estimates that the result is that “since 2012, the difficulty of launching wave jammer attacks has decreased by about 100 times”.
Although interference “in the wild” is generally an annoying crime causing a brief interruption of the GPS or a fall of a cell phone tower when someone is nearby, the risk of cheating with inappropriate hands may be greater. tall.

As the head of NovAtel Soar said, “The runny-nosed kid in the bedroom can now be our worst nightmare.”
The police began to retaliate. Curry said, for example, that jammer detection equipment manufactured by Chronos Technology had been in use for about a year and “was starting to find a way to use it as standard.”

Install a network jammer near the meeting room

The National Congress and the Nationalist Congress Party (NCP) require that frequency jammer be installed outside the locker rooms, and EVM and VVPAT are kept in the locker rooms to eliminate any possibility of tampering.

The conference also called for a 50% EVM verification against VVPAT documents to increase transparency. The results of the poll will be announced on October 24.

“Much of society thinks EVM can be impaired, which poses a threat to democracy. To ensure free and fair elections, network jammers should be installed in and around solid rooms before and during the counting process. This will eliminate the possibility of tampering via mobile towers, Wi-Fi networks and other wireless networks. We also ask you to leave candidates the freedom to choose which EVM to test against VVPAT, ”he stressed in the letter. NCP also made similar requirements.

Congress is also asking organizations that have announced their withdrawal from public opinion polls to divide their booths and constituencies. “Citizens are not satisfied with the way to withdraw from the ballot box. We suspect that withdrawing from the ballot box is an activity that helps people to accept results beneficial to the ruling party. The institutions that conduct the polls should explain the results. survey results in more detail to maintain transparency. ”

At the same time, the Election Commission took legal action against a person who committed a fault on an EVM at Navalewadi in Katav, Satara. Workers in a political party complained that even after pressing other buttons, they still voted for the BJP. However, the European Community clarified that there was no difference.

“The complainant refused to file a written complaint. He then spoke about the machine malfunction on the TV channel. In the mock vote conducted before the actual vote, the machines were inspected in front of polling officers from all political parties. We are now taking action against voters, including installing phone jammers. Said Dilip Sind, Chief Electoral Officer of Maharashtra.

Prison security audit says mobile jammers are expensive

Given that an average of three cell phones are collected each day in state prisons, an internal prison security audit conducted by the state prison department found that the installation of the 4-G cell phone jammer and body scanners might not be of much help in suppressing harassment.

In addition to the estimated high cost and the frequent escalation of human interventions, authorities have also expressed concerns about the health of individuals and prisoners.

Police Director General Sinha said that even after investing heavily in complex technology, it was not a permanent solution. It costs around 1.25 crore and disrupts cell phone signals within a 30-meter radius, he said.

He said the assessment process was conducted after the higher courts in Punjab and Haryana ordered jammers installed in all prisons last year.
“As a pilot proposal to reduce the cost of human disruptors, we have identified 24 high priority areas in 14 prisons in which serious criminals are held. It is estimated that after spending 22 million rupees, we will only cover 10% of these prisons, leaving a large gray area, ”Sinha said.

Once approved by the secretary of the central cabinet (security) secretariat, it takes about nine months to purchase and install the jammer.

“As we explore cell phone jammer, technology upgrades accelerate 5-G. In this case, it will make these jammers unnecessary. Our assessment shows that the interference will affect people within two miles of the prison. However, mobile phone service providers are considering improving the signal for users living near prisons. In this case, we might have to spend more time indefinitely on the upgrade, which is a never-ending process. ”

The National Prison Service recovered 1,086 cell phones from various prisons in 2019. According to relevant officials, in January and February of this year, authorities only seized 580 cell phones.

“We recently launched a system where prisoners can use 10 different phone numbers to call for 10 minutes a day. We are designing more effective methods to monitor unauthorized use of cell phones in prisons,” the official said. .

The ADGP said that ensuring that the installation of the wave jammer does not lead to adverse effects on the health of prison staff is indeed a concern.

Sinha said the full body scanner costs around ₹ 3 crore and cannot detect the phone or anything hidden in the body cavity.

“Full body x-ray scanners are very effective at detecting any other object hidden in the phone, rectum or other body cavities. But there are no legal penalties in the country for the use of such. scanners in prisons, ”he added.
