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.

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.”

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.

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.

There are no jammers in the prison and criminals use cell phones to blackmail

Taking advantage of the lack of a jammer, the prisoners at Mandoli appear to be doing free blackmail, filing complaints, making videos and sharing them with contacts in the glory of the unwavering 4G.

Mandoli Prison in Delhi (which has housed more than 3,000 inmates) operates without interference from mobile phone signals, as the prison administration is still waiting for 4G interference. Administrators at Mandoli Prison (opened to prisoners in 2016 to ease congestion at Tihar Prison in Delhi) confirmed that they had not installed a single jammer.

The device is used to block the cell phone signal, even if the prisoner manages to smuggle the cell phone in, it will also prevent the prisoner from using the phone in the prison.

Inmates are prohibited from carrying or using cell phones in Indian prisons.
Taking advantage of the absence of distractors, the prisoners of Mandori appear to do free extortion, file complaints, make videos, and share them with contacts in the glory of unwavering 4G.

In the past two months, Delhi police have claimed to have destroyed two extortionists led by prisoners at the Mandoli prison complex.
On Thursday last week, three prisoners were reportedly arrested (in this case formally arrested from inside the prison) and demanded 50,000 rupees for a man from Gita settlement.

Two days earlier, the city police task force (counterterrorism force) claimed to have arrested two men who had been sentenced to prison in Mandoli and killed two men, thus avoiding the murder. The police then said they intercepted the phone call from Chandban (aka Amman Yadav) who lived in Mandoli prison to his accomplices Barkishan and Mohamed Atik to eliminate the two who had not paid him protection money. people.

hidden cell jammers

A senior Home Office official said the cell phone jammer was only recently approved by the government. “We have moved for their installation and preliminary work is underway. It takes time to get permission to use jammers and install devices with the latest technology. But once installed, these devices will be the best. and will return all phones. It becomes unnecessary in prison. ”

A fortnight ago, a video of a gang leader in Uttar Pradesh showed the man recording a video on his cell phone while cooking in a Mandori prison cell, which has become popular on the media. social networks.

Prison officials said that although phone jammers may be installed in the new prison, the prison director has asked them to carry out strict inspections on a daily basis.

“Senior officials have ordered us to carry out strict security checks and warned us that we should take action if the cell phone is smuggled inside.” In the case of a small number of prisoners using cell phones, an investigative procedure has been ordered. We were warned that we would take action. Act strictly so that this does not happen in the future. “

Anti-terrorist forces acquire radar jammer

NSG and CISF will have mechanisms such as electromagnetic systems, which incorporate radars and radio frequency jammer, and may have the power to shoot down any object from low altitude to low altitude.

The National Security Agency and the CISF Industrial Security Agency may have the right to shoot down “rogue” low-flying objects such as drones and gliders under a new policy being finalized.

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.
