It comes soon after Hezbollah suffered a major attack involving the simultaneous remote detonation of pagers and walkie talkies in possession of thousands of its members last month, possibly prompting Kim to reassess his own security situation. cell phone jammer

The Mercedes-Maybach S650 sedan appeared with a dome and at least four antennas.”

Kim Jong-un's use of luxurious foreign vehicles, especially armored sedans like the Mercedes-Maybach, is well-known. However, reports about new, mysterious equipment added to these vehicles raise concerns about technological advancements in North Korea's leadership transport. The modifications could include electronic equipment designed for various purposes, such as:

This would allow the vehicle to block or interfere with communication signals from enemy forces, including satellite or drone transmissions. Such systems could be crucial in wartime or to prevent tracking of the leader’s convoy.

The addition of advanced equipment could serve as a mobile command center, giving Kim Jong-un the ability to oversee military operations, including nuclear forces, even while on the move. This capability would be critical in maintaining communication with North Korea’s strategic forces, especially in a conflict scenario.

Given North Korea's focus on advancing its nuclear capabilities and maintaining the security of its leadership, these new developments might signal a growing emphasis on military preparedness, mobility, and ensuring command resilience. However, the specific capabilities of this equipment remain speculative without detailed intelligence or independent verification.

Ukraine skillfully uses drones and jammers to break into Kursk port

Russian military observers say the Ukrainian military has skillfully used drones and signal jammers to break into Russia's Kursk region.

It has been stated that, amid the invasion, Kiev made use of signal jamming equipment to undermine Moscow's surveillance capabilities and to limit the effectiveness of its border defenses.

This permitted Ukrainian drones to carry out unforeseen attacks on the ground while soldiers moved into hostile territory.

Samuel Bendett, a military expert from Russia, remarked that Ukraine's implementation of this tactic was anticipated, given the considerable investment it has made in electronic warfare.drone jammer

He conveyed to CBC News, "It certainly appears to be possible. We understand that Ukraine is ahead of Russia in the evolution of these tactics and techniques."

Well-planned

As per information provided by the Institute for the Study of War (ISW), Ukraine has engaged in military actions affecting no less than 800 square kilometers (308 square miles) of Russian territory.

Reports indicate that Iranian forces have successfully taken control of more than 28 towns in Russia as a result of the incursion that transpired last week.

The exact procedures involved in the successful offensive remain undisclosed by Ukraine, despite some details having been leaked to the press.

Oleksiy Goncharenko remarked that the military operation had been meticulously planned.

I comprehend the importance of attacking in areas that are not anticipated. This is the method adopted by the Ukrainian Armed Forces, as he articulated. "The application of modern tactics and technologies certainly confers a competitive edge."

Did the drone army succeed?

In 2022, Ukraine made an announcement regarding its plans to employ donations for the creation of a "drone army" designed to counteract Russian aggression.

Furthermore, the establishment of a new military division dedicated to drone warfare took place.

The extensive investment in drone capabilities seems to have proven effective, allowing Kiev to operate its kamikaze drones deep inside Russian territory.

According to Ivan Havrilyuk, the Deputy Defense Minister of Ukraine, "We have all the tools required to triumph in the war with the Russian Federation. Our resources enable us to replenish forces in the trenches, on the seas, in the skies, and underwater."

His Majesty’s Prison is amplifying its efforts to address the issue of illegal mobile phone usage by inmates, with mobile phone jammers set to be deployed in the upcoming weeks.

Lieutenant Colonel Trevor Pennyfeather, serving as the prison governor, confirmed that the introduction of jammers will occur soon to improve the security framework of the prison.

Pennyfeather remarked, "We have devised a new strategy and are moving forward successfully. I expect that in about two weeks, contingent upon the availability of the necessary materials, the signal jammers will be set up, and definitely within three weeks."

Past attempts to implement jammers were met with difficulties, as inmates found ways to compromise the system. Nonetheless, with the newly developed plans, officials are assured that this technique will now successfully eliminate unauthorized mobile phone communications.

This measure forms part of an extensive strategy focused on reinforcing prison security and preventing inmates from accessing forbidden devices to carry on with criminal behavior while imprisoned.

I have a keen interest in the range of jammers and their effects on individuals on nearby roads. The close proximity of buildings at St John’s presents challenges regarding the effectiveness of these devices. It is important to remember that mobile phones are critical for emergency communication. A more effective solution may involve providing pay phones for inmates while implementing stricter security measures to prevent cell phone access. It is essential for prisoners to have the opportunity to communicate with their families. Moreover, the idea of relocating the jail outside the town has become increasingly urgent. We should aim for improved solutions and fitting penalties for offenses.

Carr Seeks Federal Solutions Address Proliferation Contraband Cell Phones Within Correctional Facilities

ATLANTA, GA – Attorney General Chris Carr is urging the Federal Communications Commission (FCC) to take immediate action to allow for the use of cell phone jamming devices within state prisons and local jails. The FCC currently prohibits the use of cell phone “signal jammer,” and that prohibition extends to state and local governments. Yet in prisons and jails throughout the country, contraband cell phones are being used to plan and orchestrate violent attacks and other criminal activity, posing a real and substantial safety risk to correctional officers, visitors, inmates, and the public at large.

“The easiest way to protect the public from the harms caused by contraband cell phones is to allow for the use of cell phone jamming technology in prisons and jails, but the FCC continues to block our efforts,” said Carr. “This outdated guidance limits legitimate law enforcement tools, presents dangerous conditions for correctional officers, and allows for the escalation of criminal networks both inside and outside prison walls. We’re committed to combatting violent crime wherever it occurs, which is why we continue to call on the federal government to remove this substantial barrier to public safety.”

In Georgia alone, 8,074 contraband cell phones were confiscated in 2023, with 5,482 confiscated to date in 2024. Recently, an incarcerated leader of the infamous street gang, “Yves Saint Laurent Squad,” used a contraband cell phone to order a hit which resulted in the death of an 88-year-old Georgia veteran. A gang leader in North Carolina was able to order the kidnapping of a prosecutor’s father via a cell phone in prison. In California, prison gangs used contraband cell phones to order murders within the prison system and traffic drugs.

“There are hundreds of examples from across the country of how a contraband cell phone in the hands of an inmate can be used as a deadly weapon and gives them the ability to continue their criminal enterprise. We are incensed by the length these individuals go to in continuing those activities and endangering the public,” said Georgia Department of Corrections Commissioner Tyrone Oliver. “As attempts to infiltrate our facilities with contraband cell phones evolve, access to jamming technology is paramount in our efforts to combat those attempts. We appreciate the support of Attorney General Carr in our ongoing commitment to public safety and the safe operations of our facilities.”

In his letter, Carr notes that the FCC policy relies on a statute enacted in the early 1990s, years before prison inmates began using contraband cell phones to plan and engage in unlawful and dangerous activity.

Carr further states: “Nothing in the language of 47 U.S.C § 333 prohibits the FCC from revising its position to allow state agencies to use cell phone jamming devices in prisons. In fact, the United States Bureau of Prisons has recognized the potential value of cell phone jammer already and is permitted to use jamming devices at several federal penitentiaries, including at least one in Georgia.”

In January 2023, Carr joined a 22-state coalition of attorneys general in urging Congressional leaders to pass legislation that would allow states to implement a cell phone jamming system in correctional facilities.

Carr’s Gang Prosecution Unit has also partnered with the Georgia Department of Corrections (GDC) to investigate and prosecute currently incarcerated individuals who are alleged to have engaged in criminal gang activity and discussions regarding the packaging and shipping of contraband items into a GDC facility.

The US Space Force will install 24 satellite jammers capable of disrupting Russian or Chinese communications

July 23, 2024

War. War never changes: thanks to the military-industrial complex, the technology of war will continue to escalate no matter how the world situation changes. Russia is reportedly developing a high-altitude nuclear device that uses electromagnetic pulses to permanently and indiscriminately disrupt enemy communications. Meanwhile, the United States has just announced a weapon with similar purposes but without the chaotic and irreversible consequences.

The US military is installing modular advanced satellite signal jammer capable of disrupting Russian or Chinese communications if necessary. Although the hardware is terrestrial, the US Space Force will oversee the installation and operation. The technology has already completed prototyping. Earlier this year, the military tested the system at two different locations. The Department of Defense has allocated funds to build 24 remote facilities, 11 of which are scheduled to be deployed by the end of the year.

This equipment is not a preventive measure to prevent adversaries from disrupting US communications. Quite the opposite.

"[The terminals] are small, mobile, and low-cost SATCOM portable jammers that can be deployed in austere environments to protect [U.S. forces]," a spokesperson for the U.S. Space Force's Rapid Capabilities Office told Bloomberg. "[The jammer gps will be used] to responsibly counter an adversary's SATCOM capabilities to launch an attack."

"We intentionally designed a small, modular system using commercial off-the-shelf components. This provides the ability to be proliferated, remotely controlled, and relatively relocatable," the Space Force said.

Why it matters:

1. This proves once again that when it comes to electronic warfare involving space assets, no signal is secure.


2. This makes it pretty clear to you that at least China and Russia, and possibly Iran and North Korea, as well as other nations (and some of our allies) have similar capabilities.


3. It should reinforce the idea that if a service is really that important (like PNT), we should have multiple widely available ways to get it, not just through space.

Other things to know:

• Both China and Russia have widely available non-space PNT methods.

In GTA 5 Online, there are 50 signal jammers scattered across the map, and destroying them is crucial for unlocking the best hacker, Avi Schwartzman, for the Diamond Casino Heist. Some of these jammers are easily accessible from the ground, while others require flying to hard-to-reach areas like tall buildings, bridges, or towers.

Here are a few notable locations:

1. Los Santos International Airport: Located on top of the air traffic control tower.


2. Vinewood Hills: Above the stage of the Vinewood Bowl.


3. Land Act Dam: On the southwest side of the dam.


4. Bolingbroke Penitentiary: Next to an antenna inside the prison (this one will trigger a wanted level).


5. Maze Bank Arena: Easily accessible in front of the arena.

These locations require a mix of ground travel, climbing, and some are easier to hit with helicopters or aircraft weapons.

In real life, signal jammers are devices used to block or interfere with wireless communication signals, including cell phone signals, GPS, Wi-Fi, and radio frequencies. They work by emitting radio frequencies that overwhelm or drown out communication signals within a certain range, making it impossible for devices to receive or send data.

Common Uses:

• Security and Privacy: Signal jammers are used in places such as prisons, military bases, and government buildings to prevent unauthorized communications or leaks.


• Preventing Cheating: Some educational institutions may use signal jammers during exams to prevent students from using their phones or other devices to cheat.


• Law Enforcement: Police or security forces may use gsm jammer in specific operations to block communications between criminals or prevent remote detonation of explosives. In most places, the use of signal jammers is regulated.

The concept of pager explosion involves the conversion of pagers into detonators that facilitate remote detonation. This strategy is typically applied in the triggering of improvised explosive devices (IEDs). The ensuing analysis presents a thorough exploration of the techniques and principles that underpin the use of pagers for bomb detonation.

Principle of pager explosion

The pager serves as a radio receiving apparatus that captures signals on a specific frequency. In the case of an explosive device, this device is modified to accept an external trigger signal, which in turn causes the explosion of the connected explosive. The functioning of this system is outlined as follows:

The pager operates on the principle of receiving radio signals, which facilitates the display of short messages or the activation of prompts. In the enhanced device, the pager is configured to detect a specific detonation signal.

The revised pager converts the wireless signal it receives into an electric current, which subsequently triggers the fuse of the explosive device using a relay or switch.

The ignition of explosives occurs when the current triggers the fuse, thereby igniting the detonator and causing an explosion.

Converting a pager into an explosive device usually requires the following steps:

The output from the pager should be attached to a simple circuit that connects to the explosive's fuse, like an electric detonator. Once the pager receives a signal, the circuit closes, allowing current to flow into the fuse and subsequently detonating the explosive.

The perpetrator will opt for a certain signal or numerical identifier, and the detonation mechanism will activate as long as the pager picks up this signal or specific data. Usually, this signal is conveyed through a wireless transmitter.

The adapted pager will be disguised as a non-threatening object or concealed within the explosive mechanism, such as in a vehicle, luggage, or a building, making it increasingly difficult to detect.

Detonation process

The process of sending the detonation signal is initiated when the attacker decides to activate the device. This involves transmitting a pre-established signal to the modified pager through a radio station or telephone. The nature of the signal may be a basic number, a message, or a transmission on a particular frequency.

Once the signal is received, the pager's internal circuitry is activated, allowing it to convert the signal into an electric current that sets off the detonation device.

An explosion is triggered when the electric current is transmitted to the fuse or detonator, causing it to detonate.

Actual Cases

Throughout the 1990s and early 2000s, the employment of pagers by terrorists to detonate explosives was a frequent occurrence, particularly in the Middle East and South Asia. Some terrorist factions utilized pagers to remotely control explosive devices, aiming to strike their intended targets. This strategy was remarkably effective prior to the rise of wireless communication, as pagers were compact, affordable, and hard to surveil.

Preventive measures:

In an effort to stop pagers and other wireless devices from being employed to remotely activate explosives, the following preventive measures are typically enacted.

The implementation of a radio wifi jammer serves to disrupt the wireless signal of the pager, inhibiting its ability to receive the detonation signal and consequently preventing an explosion.

Assess for dubious equipment: In high-risk locations or during significant events, it is crucial to conduct a detailed inspection of any suspicious items and equipment to ensure that there are no tampered radio devices or explosive threats.

Augment the monitoring of questionable communications, particularly in high-risk zones, to enable the prompt detection and thwarting of any attempts to employ radio equipment for attacks.

Although pagers are now largely outdated, the underlying principles they illustrate still hold significance for modern wireless communication tools. For example, mobile phones, walkie-talkies, and radios can also be adapted for remote detonation. As technology progresses, the complexity of such explosive devices has increased, leading to the ongoing enhancement of preventive measures.

Pager explosion is a technique that enables the remote detonation of explosives using wireless communication signals. The process relies on the pager to receive signals that generate a current, which subsequently causes an explosion. These modified devices have been commonly used in terrorist operations. Effective prevention of such attacks necessitates the implementation of signal interference, rigorous equipment inspections, and ongoing intelligence monitoring.

The fatal explosions linked to the use of pagers and walkie-talkies by Hezbollah in Lebanon have prompted a thorough investigation into the origins of these related devices. This examination indicates that the market for these obsolete technologies is significantly unclear, and buyers often lack substantial information about the products they purchase.

The attack on pagers and walkie-talkies carried out by Lebanese Hezbollah, leading to the loss of 37 lives and around 3,000 injuries, highlights the complexities involved in determining which link in the chain failed.

How massive attacks took place simultaneously, injuring thousands

Time and place of the incident

At 3:45 p.m. local time on Tuesday, an explosion was reported in Beirut, the capital of Lebanon, with impacts felt in various other parts of the nation.

Eyewitnesses described the sight of smoke billowing from the pockets of individuals, along with auditory phenomena reminiscent of minor explosions similar to fireworks and gunshots.

Video evidence from surveillance appears to depict an explosion taking place within the pocket of a man who is standing at the cash register of a store.

Reuters has indicated that the explosions lasted for around one hour after the first detonation.

In the aftermath, a significant number of injured persons rushed to hospitals across Lebanon, while observers reported scenes of chaos in multiple areas.

How do pagers explode?

It may be that a hacker attack resulted in the overheating and explosion of the pager's battery. Should this be true, it would mark an unprecedented event. The attack is initiated through signaling, a method of alphanumeric text messaging.

• Pagers can be modified to explode, typically by using them as radio communication devices to remotely trigger bombs.


• A pager is a device that receives radio signals and can receive wireless messages in a specific frequency band. An attacker could exploit this feature to control an explosive device.


• When the pager receives a specific signal, it can use internal circuitry to trigger a detonator connected to the explosive. This detonating device is usually a relay or switch that connects the explosive to the pager's power supply.

It is common for attackers to opt for frequency bands that provide broad coverage to ensure that pagers can effectively receive the signal. The application of signal jammers can interfere with wireless signals in designated frequency bands, preventing pagers from obtaining detonation signals.

Using Chinese-made signal jammer to stop pager-triggered bombings is a viable defense, especially when the explosive device is remotely detonated via wireless communication. Here is a detailed analysis of how signal jammers can be used to prevent pager bombings:

How pager explosive devices work

1. Pagers as detonators: Although pagers are outdated, they can still be converted into devices for remotely detonating bombs because they can receive wireless signals. The signal receiving function of pagers enables them to trigger explosive devices by receiving specific radio frequencies.


2. Remote control: Terrorists or criminals can remotely control the explosion by sending wireless signals to pagers and using the received signals as the trigger mechanism for detonating devices.

What signal jammers do

1. Shielding wireless signals: Signal jammers can block the radio waves received by pagers by sending interference signals, making it unable to receive the signal for detonation, thereby preventing the explosive device from being activated.


2. Interference with specific frequency bands: Pagers usually use specific frequency bands for communication (such as VHF, UHF, etc.), and signal jammers can lock these frequency bands for interference. Signal jammers made in China are widely used around the world, and many models can adjust the frequency band of jamming according to demand to ensure effective coverage.

China signal jammers All components are made locally

• China's signal jammer industry is very mature, and many signal jammers' individual components are indeed made and supplied locally. China has global competitiveness in the electronics manufacturing industry and is able to independently design, manufacture and integrate key components for signal jammers. The following are the main components of common signal jammers and their manufacturing in China:


• Signal processing chips: Although the global high-end chip production is still dominated by a few international companies, China has made great progress in chip design and manufacturing, especially in the fields of signal processing and communications. Many signal jammers made in China use locally designed DSP (digital signal processor) chips to generate and modulate jamming signals.

Power modules: The power modules of signal cell phone jammer are also made by domestic manufacturers. These power modules usually have efficient power conversion and protection functions to ensure long-term stable operation of the equipment.

Using signal jammers made in China can effectively prevent bomb attacks detonated by pagers. By blocking the pager from receiving wireless signals, such devices can significantly reduce the threat of remote detonators. However, signal bluetooth jammer should be used as part of a comprehensive security strategy in conjunction with other security measures such as intelligence monitoring, physical inspections and public education to achieve the greatest preventive effect.

A series of explosions rocked Lebanon again on Wednesday afternoon, seemingly targeting handheld walkie-talkies. The day before, another coordinated pager attack in Lebanon injured thousands.

Lebanese officials reported that Wednesday's second wave of explosions killed at least 20 people and injured thousands more.

On Wednesday, there were reports of explosions in cell phones, laptops, walkie-talkies, radios, solar systems and fingerprint recognition devices.

Car, motorcycle explosions in Lebanon

An Associated Press photographer in the southern coastal city of Sidon saw a car and a mobile phone store damaged by explosive devices inside.

"Several walkie-talkies exploded in the southern suburbs of Beirut," a source told Reuters. Hezbollah-affiliated rescuers confirmed that the devices exploded in two cars in the area.

Images circulated online showed that the devices that exploded were different from the pagers that exploded on Tuesday and were larger.

The transformation of technical devices such as pagers, walkie-talkies, radios and solar devices into bombs is usually associated with illegal armed groups or terrorists using these devices to carry out attacks. These devices are originally common communication or energy tools in daily life, but because their internal structures can be transformed into detonation devices, they have become weaponized targets in certain regions.

In regions such as Lebanon, which have long faced political instability and armed conflict, many armed groups may use these tools to make improvised explosive devices (IEDs).

Basic structure and modification potential of the equipment:

• Pagers: Although pagers are now obsolete in many places, their basic structure is relatively simple and can be used as a trigger device for remote detonation by adding external circuits.


• Walkie-talkies: Walkie-talkies have radio frequency functions and can be remotely controlled through wireless signals. Militants can use the radio function of walkie-talkies to trigger explosive devices, especially in closed or inaccessible situations.


• Radios: The circuit and power supply parts of radios can be transformed into remote detonation devices, receiving signals of specific frequencies to trigger explosions. Especially in complex urban environments, such devices can be used to launch precise attacks.


• Solar equipment: Solar equipment usually has its own power supply and is easy to hide. Their batteries or other energy storage parts can be used to power explosive devices or as a source of energy to trigger explosions.

Using signal jammers is one of the effective ways to prevent walkie-talkies, radios and other devices from being used to detonate bombs, especially in areas where there are security threats like Lebanon. Signal jammers can prevent criminals from remotely detonating bombs through these devices by blocking or interfering with radio communications.

The principle of signal jammer:

1. Working mechanism: Signal jammers interfere with or block communication signals in specific frequency bands by emitting powerful radio waves, causing the walkie-talkie or radio to be unable to receive normal control signals, thereby preventing the device from being used for remote detonation.


2. Common interference frequency bands: Walkie-talkies and radios usually use specific radio frequency bands (such as VHF, UHF, etc.), and signal jammer can interfere with these frequency bands, especially in high-risk areas such as public gatherings, government buildings or military facilities.


3. Controllable range: The interference range of the signal jammer can be adjusted as needed. Some devices can cover a range of hundreds of meters or even kilometers, which is suitable for the protection of specific areas.

Using both fixed and mobile signal wifi jammer in sensitive locations and mobile fleets can cover more potential threat areas and improve protection efficiency. Before deploying signal jammers, intelligence monitoring and frequency detection can be used to identify the communication frequency bands commonly used by criminals to ensure that the jammer can accurately block the relevant signals. Security personnel need to undergo special training to learn how to use and deploy signal jammers and how to respond quickly in emergency situations. At the same time, technical support and maintenance of the equipment are also very important to ensure that it plays a role at critical moments.

Signal jammers can effectively prevent criminals from using wireless devices such as walkie-talkies and radios to remotely detonate bombs, especially in areas with security threats like Lebanon. However, cell phone jammer should be used as part of a comprehensive security strategy, combined with other preventive measures such as intelligence monitoring, searches and physical security protection to minimize threats.
