jammer

In connection with the recent scandal in South Korea, two men have been taken into custody while another pair is being probed. A significant number of concealed cameras were unearthed inside digital TV boxes, wall sockets, and hairdryer holders.

Hidden cameras were allegedly found by a tourist staying at an Airbnb in Miami.

Upon his arrival at the two-bedroom apartment he had rented, Max Vest stumbled upon two inconspicuous devices discreetly plugged into electrical outlets. One of these devices was cunningly concealed beneath a large mirror, while the other remained hidden beneath an air freshener. It was later confirmed by the police that these devices were, in fact, covert cameras.

Law enforcement authorities have apprehended an Airbnb host who was found guilty of surreptitiously filming over 2,000 tourists.

In November 2021, Jay Allee was first taken into custody when the authorities were notified by a guest at his San Antonio rental regarding a power adapter that was camouflaged as a camera. The local police later confirmed the device to be a camera.

A man has been formally charged with the offense of secretly installing a covert camera within the confines of a restroom at a Starbucks coffee shop.

The prevalence of hidden cameras is far greater than most people realize. Esteemed publications like The New York Times, Washington Post, and BBC have extensively covered this issue, bringing it to public attention. It is disconcerting to think that any hotel, Airbnb, or restroom could potentially house a covertly installed spy camera without your knowledge.

Individuals who have undergone extensive examinations are well-acquainted with this phenomenon, as it is frequently mentioned prior to the exam that mobile phone signal jammers might be deployed within the examination venue. In certain instances, the examination rooms themselves explicitly notify candidates through the integrated speakers, ensuring that they are aware of the presence of mobile phone signal jammers within the examination premises.

The primary purpose of a mobile phone signal jammer is to disrupt or block the transmission of signals between mobile devices and cellular towers.

Mobile phone signal jammers are employed to disrupt mobile phone calls and network transmission within a specific vicinity. Typically, these devices find application at college entrance examination venues to deter certain students from surreptitiously carrying advanced electronic gadgets into the examination room for cheating purposes. However, it should be noted that the primary objective of a cell phone signal jammer extends beyond this particular scenario.

To guarantee the security of crucial locations and positions, numerous confidential establishments will deploy mobile phone signal jammers in select sensitive areas, adhering to pertinent management regulations and requirements. These jammers effectively disrupt the transmission and reception of mobile phone signals, including 2G, 3G, 4G, 5G, WiFi, Bluetooth, and other signals, within a specific range. Consequently, communication connections and data transmission become unattainable, effectively enforcing a mandatory ban.

Mobile phone signal jammers possess the capability to obstruct mobile phone signals. These devices are commonly employed in examination rooms to deter candidates from engaging in cheating activities. Due to their remarkable shielding effectiveness, mobile phone signal jammers have raised concerns among individuals regarding their potential impact on base station signals within the vicinity or surrounding communities.

A mobile phone signal blocker operates by emitting targeted signals to disrupt, obstruct, or impede the connection between a mobile phone and the base station. As a result, the mobile phone is unable to receive any signal or access network services. Additionally, the text messages transmitted and received by the mobile phone will be distorted, rendering the original content unrecognizable.

An installation plan for the outdoor signal jammer is being devised.

In order to install the signal jammer outdoors, it is crucial to implement waterproofing and lightning protection measures. It is generally advised to opt for a dedicated installation box designed specifically for signal jammers. This installation box is constructed using flame-retardant plastic and can be extended with additional meters on both sides. It features a window-type ventilation position to enhance heat dissipation. The antenna of the mobile phone jammer protrudes from the top of the box through a sealed hole using hot melt glue. At the bottom of the box, there are power input holes and diversion holes to prevent water accumulation.

The signal jammer's host is positioned at the top of the box, while the antenna protrudes from it. It is crucial for the antenna to extend out of the box to maintain the optimal shielding effect. As for the power adapter, it should be placed in the lower and middle section of the box.

It is imperative to implement lightning protection measures when installing the signal jammer (along with the installation box) outdoors, for instance, on the exterior wall of a building. This precaution becomes even more crucial in areas prone to thunderstorms. Extra attention should be given to ensure safety in such circumstances.

The installation of a lightning rod on the shield is the actual measure taken for lightning protection. In case a ready-made lightning rod is not available for purchase, one can create their own lightning rod using the following method.

You have the option to select 3-4 steel bars ranging from 5-10mm in diameter and 50cm in length. One end of each bar is sharpened to resemble a needle, while the other end is welded together to create a "Y" shape. The welded end is then connected to a steel bar with a diameter of 2-3mm. The ground, where the iron wire is protected by PVC pipes, is connected to one end of the iron wire. This iron wire is further connected to an iron strip. Typically, the iron strip measures around 50-100cm in length and 2-5cm in width, and is driven deep into the ground. In case iron strips are not readily available, you can substitute them with 10mm steel bars.

It is imperative to install the lightning rod at a height of 30-50cm above the antenna of the mobile phone signal jammer. To avoid any interference, it is crucial that the lightning rod, including the grounded steel wire, does not come into contact with either the mobile phone jammer or the installation box. The appropriate distance between them should be maintained.

As a result of the lethal consequences inflicted by explosive drones relentlessly pursuing their vehicles, Russia seems to be adopting jamming technology on its tanks as a countermeasure.

On August 2, 2022, DJI Matrice 300 reconnaissance drones were observed conducting test flights in the vicinity of Kyiv. These drones were being prepared for deployment to the front line. The test flights were captured in a photograph taken by SERGEI SUPINSKY/AFP and depict the advanced capabilities of these drones.

DJI Matrice 300 reconnaissance drones were tested near Kyiv on August 2, 2022, before being sent to the front line. A photo of the test flights was taken by SERGEI SUPINSKY/AFP via Getty Images.

Based on the visual evidence, it appears that Russia is deploying jammers on its tanks and vehicles, specifically intended to interfere with the drones utilized by Ukraine.

An advertisement video highlights the jammers, while Russian Telegram channels collaborate in crowdfunding efforts to secure additional units for the Russian troops.

In the ongoing conflict in Ukraine, both warring factions are striving to find effective measures to combat the menace of drones.

To address the ongoing threat of drones exploding, it appears that Russia is outfitting its tanks and vehicles with signal jammers.

The recent development exemplifies the ongoing electronic warfare dynamics witnessed on the battlefield. In response to the escalating threat posed by unmanned aerial vehicles (UAVs), both factions are intensifying their defensive efforts to safeguard their troops. These UAVs have emerged as a major peril, relentlessly targeting and eliminating main battle tanks, armored vehicles, supply trucks, infantry squads, and even individual soldiers.

A Russian Telegram channel recently posted a photo of a tank that was camouflaged and had a cell phone jammeron its roof screen. The tank was also fitted with a cage to safeguard against first-person view (FPV) drone attacks.

The Volnorez C-UAS EW jammer has been identified by observers as the cone-shaped system in question. Prior to this, the same channel had shared multiple photographs featuring the unboxing and attachment of this jammer system onto various vehicles, including tanks and pickup trucks.

Furthermore, a video was circulated to advertise the system, providing insights into its manufacturing process and showcasing its successful interference with Ukrainian drones. Reports indicate that Russian Telegram channels have launched crowdfunding campaigns to secure additional GPS jammers for deployment within Russian units.

The installation of jammers on vehicles by Russia indicates their increasing concern about the danger of FPV drone attacks. Nonetheless, it is unclear how many drone jammer are currently being used or how effective they are. In the past, tank and armored crews have resorted to welding cages onto their vehicles as a makeshift defense.

Nonetheless, even with the deployment of electronic warfare defenses by military forces, both sides involved in the war have been engaged in a relentless pursuit to fabricate drones that possess immunity against jamming. These sophisticated systems could potentially compel anxious vehicle crews to seek alternative remedies.

A new drone has been introduced by Ukraine, claiming its ability to conduct missions in enemy-controlled areas with remarkable efficiency. Notably, this drone has been specifically engineered to counteract Russian attempts to disrupt its communication signals.

Ukraine claims that the Backfire is equipped with a GPS antenna for navigation purposes and has a range of 20 miles.

The dominance of UAVs in modern warfare has spurred Ukraine and Russia to make notable progress in their drone technology.

The latest drone introduced by Ukraine has the remarkable ability to traverse extensive distances beyond enemy borders while effectively countering ongoing Russian attempts to disrupt its operations.

Constant technological advancements and the omnipresence of drones on the battlefield and in the airspace have fueled the ongoing drone war between Russia and Ukraine, marking the latest development in this conflict.

The Backfire unmanned aerial vehicle (UAV) was introduced by Mykhailo Fedorov, the Vice Prime Minister of Ukraine for Innovation, Education, Science, and Technology, on Monday. Fedorov referred to it as a "formidable drone" that can fly up to 20 miles and cause "tremendous losses" to the enemy's rear positions.

Ukrainska Pravda reported that Federov mentioned the drone's ability to aid Ukrainian forces in striking Russian artillery, logistics hubs, enemy storage points, and command posts.

According to Fedorov's statement on X, the social networking site formerly referred to as Twitter, the Backfire's key characteristic is its "highly effective GPS antenna, resilient against Russian interference" and electronic warfare. Ukrainska Pravda conveyed that Fedorov also emphasized that this antenna is "nearly impervious to disruption," and thanks to the drone's "complete autonomy, the Russians cannot trace its coordinates and ground crew."

Ukraine's Backfire drone is on the verge of being mass produced and will soon join the country's array of UAVs in combat. Fedorov revealed that it has already completed more than 50 successful missions in the recent months.

Ukraine's latest contribution to the ongoing drone warfare is the Backfire, a development that has kept both sides on high alert due to the constant need for innovation driven by technological advancements. In combat scenarios, troops have increasingly relied on drones, with one Ukrainian service member disclosing in September that his unit had barely used rifles in the past six months, instead heavily relying on drones for their fighting capabilities.

Amidst the ongoing conflict, cost-effective UAVs have proven to be highly efficient in eliminating tanks and armored vehicles, which are primarily asymmetrical targets, as well as any mobile entity encountered on the battlefield. Regularly documented videos from the war exhibit first-person view (FPV) drones engaging in collisions with tanks, penetrating open hatches in armored vehicles, discreetly approaching troops in trenches, and causing explosions upon impact.

The continuous hum from above acts as a constant warning of the lurking danger, signifying that an unassuming target may fall victim to a sudden attack by an exploding UAV. Both Ukraine and Russia are actively involved in a race to acquire superior drone capabilities, driving them to pursue innovative technologies in order to gain an advantage over their adversary.

The significance of operators cannot be overlooked in the progress of Ukraine and Russia's specific flight and control abilities, in addition to the advancements in autonomous drones. Nevertheless, their importance also exposes them to enemy threats, leading to operators engaging in drone-based conflicts.

Efforts to counter the growing impact of drones have intensified over time. The front lines are now equipped with advanced jamming signal technology that disrupts the navigation controls of drones. While drones controlled by operators are usually less susceptible to such interference and are more affordable if lost or destroyed in battle, gps jamming still poses a significant obstacle. This underscores the vital importance of Ukraine's new Backfire system in blocking Russian interference, granting Ukraine the upper hand to maneuver along and behind enemy lines.

PENTAGON: The United States Army is straining to phone fund the increasingly important electronic warfare wifi capabilities it has developed since the gps fall of the Soviet Union. The Army possesses over 32,000 short-range defensive jammer device to block roadside explosives, but an offensive handheld jammer will not be available until 2023, according to current plans.

"Can that be sped up?" "Yes," replied Col. Jeffrey Church, the Army's Pentagon staff's chief of electronic warfare. "Technology exists today that does a lot of things that we would like MFEW [the Multi-Function Electronic Warfare system] to do," he said, adding that some of it might even phone be purchased commercially by the Army.

However, with the Army decreasing faster than any other service and sequestration looming, "there's no money tree," Church told me in an interview. "So if you're going to grow a robust electronic warfare program, who's going to pay for that?"

where is the Army's electronic warfare today?

"I have a theory. I've got folks. "I have facilities," Church explained. "What we lack is equipment."

"If you go to a unit gps today in the Army and phone you say, let me see your 'electronic warfare equipment,' and you go to the EWO (Electronic Warfare Officer) and he opens up his wall locker, it's empty," Church went on to explain. "Right now, the Army relies on borrowing assets from other people," such as the Growler aircraft from the Navy.

"Our senior army leaders have known and continue to know that electronic warfare is something the Army must have," said Church, the Army's senior electronic warfare specialist. (The fact that the highest senior EWO is a colonel rather than a general demonstrates how nascent the field is). "It's a matter of resource prioritization and wifi where do you fall in those priorities."

What category does electronic warfare fit under? The Pentagon's fiscal 2016 budget contains $2.5 million for something called the Electronic Warfare Planning & Management Tool, which is a rounding error for a significant weapons program. EWPMT, which went into service in September 2016, is much-needed software that will allow electronic warfare forces to gather data from sensors such as Navy Growlers and the Army's DCGS-A intelligence network.

"EWPMT is what allows them to see the phone battlefield in the electromagnetic environment," Church explained, "so you can tell your commander, 'this is where we have interference.'" This is the situation. This is where the adversary is. I'm not sure what it is, but gps I'm getting some sort of signal."

EWPMT, on the other hand, is now a command-and-control system with nothing to command and control. The 32,000 CREWS gps blocker that defend wifi Army vehicles from roadside explosives are strong at short range, but they aren't connected to any type of network, so EWPMT can't utilize them as a data source, much alone manage them. For the particular circumstances of Afghanistan and Iraq, the Army possesses just a few longer-range systems purchased using emergency funding and/or quick equipping authorities.

"We got good technology into wifi the field to save soldiers' lives," he remarked. "We didn't get any programs of record, so we phone don't have budgets, we don't have base dollars."

The Multi-Function Electronic Warfare system is designed to address this issue. MFEW will be a network of sensors and wifi blocker deployed on various sized drones, ground vehicles ranging from Humvees to heavy trucks, stationary locations, troops' backpacks, and maybe helicopters.

Church underlined that, unlike Cold War electronic warfare units, MFEW will not require a specialized vehicle to carry it: "The Army can't afford it," he stated, and current miniaturized electronics don't require it. Instead, MFEW will ride on ground vehicles while they go about their regular tasks, giving data to and receiving commands from Army electronic warfare experts at the gps command post. MFEW will be another plug-and-play module on drones, to be used or not depending on the task, as many specialized sensors already are.

How near is this vision to becoming a reality? "Right now, MFEW is not a program," Church explained, limiting the Army's capacity to support it. MFEW is now a "concept" in the arduous process of becoming a formal Army requirement. "We're on about the fifth rewrite of the MFEW CDD (Capabilities Development Document)," Church stated in a statement. MFEW can become a program of record and receive base budget money after thephone CDD is completed and authorized.

The MFEW is expected to start service in 2023 and achieve full operational capability (FOC) in 2027. We're still playing catch-up till then.

"Guys like the Russians, guys like the Chinese, their surrogates, they've spent the last 20 years continuing the development and acquisition of an electronic warfare capability, whereas… the Army got out of the business," he stated. When the battlefield was brought back to life, he stated, "Army electronic warfare started from nothing, and it started from nothing in a combat environment where a lot of US soldiers were being killed or wounded due to the radio-controlled IED."

Church stated, "Now we have to take this to the phone next level, and MFEW is the next level."

Of course, all of this is taking place as the Pentagon's senior leadership assesses its electronic warfare portfolio. The newly formed Electronic Warfare Programs Council is the place to be; it is led by Frank Kendall, the undersecretary for acquisition, technology, and logistics, and Adm. James Winnefeld, vice chairman of the Joint Chiefs of Staff.

Electronic Jamming Tactics

Jamming has increased in sophistication as electronic warfare gps has developed and phone includes an array of tactics. Barrage jamming is performed against two or more frequencies phone. This can be useful when the aggressor does not know exactly which radio or radar frequencies their adversary is using. Nonetheless, they may know with reasonable gps certainty which phone waveband of frequencies they may be using. Spot jamming is performed against specific frequencies known to gps be in use.

The advent of solid-state electronics in the 1960s revolutionized jamming technology. It facilitates the development of complex phone digital radio frequency memory (DRFM) systems. These are particularly useful for jamming radar equipment. DRFM detects incoming radar signals, samples the signal, and then cleverly sounds an alert before retransmitting it to phone the radar. This new false signal could confuse radar by showing two or gps more targets where there used to be only one. The target may move faster or slower than its actual speed. This strategy is called deception gps jamming.

Likewise, DRFM can collect and send false signals to trick the radar into believing there is a more prominent or attractive target in its field of view than the one initially detected. This strategy is called temptation interference. In the long term, the emergence of artificial intelligence will make interference tactics and techniques increasingly sophisticated.

Jamming is the basis of the electronic attack mission. Electronic attack is a subset of the broader discipline of gps electronic warfare (EW), which is discussed in more detail elsewhere. Jamming was first used during World War II to attack radar and radio phone equipment. Both latter systems transmit phone radio signals. Radar does this to detect and track objects, radio does this to send and receive voice and data traffic.

In the simplest case, the purpose of cell phone jamming is to impair a radar or radio's ability to perform its mission, or even prevent them from completing it entirely. The jamming process also uses radio signals, but in a way that attacks these systems. Simply put, jamming is gps an attack using artificially generated radio interference. An example of how interference works can be seen when a car drives under power lines with the radio on. The sound of the radio was suddenly drowned out by interference. This is caused by electromagnetic radiation from power lines.

Interfering signals, called waveforms, are sent to the radar or radio's antenna. The antenna should detect the gps signal. To ensure this, the signal is sent at a frequency that the antenna can gps detect and that matches the phone frequency of the interfering target signal: If the radar sends a signal at a frequency of 3.6 GHz/GHz, the signal must be the same in the event of a malfunction.

However, successful radar or radio jamming depends on more than just the frequency of phone the interfering signal. Signal amplitude is also important. Let's consider a radio that receives amplitude traffic at a specific wattage. If the interfering signal is weaker than the signal received by the radio, these signals will remain uninterrupted. Interference signals were also detected, but were too weak to have a noticeable effect.

If the interfering signal is stronger than the traffic received by the gps radio, the former will be "washed away." In electronic warfare, jamming is effective when a radio or radar device is receiving rather than transmitting. This is because the incoming radio signal is already relatively weak. This reduces the power required for the signal jammers to be effective. To explain how improvisation works, imagine a violin soloist and a heavy rock band on the same stage. The solo violinist begins to play, but their music immediately becomes inaudible as the rock band begins. This does not mean that the phone violinist's music has stopped, just that the volume of the orchestra drowns out the soloist's voice.

Starlink and other low-Earth orbit constellations face new security risks

Russia's invasion of Ukraine in 2022 really threw Ukrainian communications into a tailspin: Shortly before the invasion, Russian hackers disabled Viasat satellite ground receivers across Europe. Then entrepreneur Elon Musk stepped in and offered access to Starlink, SpaceX's growing network of low-Earth orbit (LEO) communications satellites. Musk soon reported that Starlink was suffering from cell phone jamming attacks and software countermeasures.

In March, the U.S. Department of Defense (DOD) concluded that Russia was still trying to block Starlink, according to leaked documents from U.S. National Guard pilot Ryan Teixeira seen by The Washington Post. According to the "Defense One" website, the Ukrainian military also blamed the Starlink problem on Russian gps jamming. If Russia blocks low-Earth orbit constellations, this will be a new height in the silent war between space and earth communications.

“There’s really not a lot of information about it,” said Brian Weeden, program director at the Secure World Foundation, an NGO focused on space governance. However, Weeden added, "My sense is that Starlink is harder to jam or interfere with [than GPS satellites]."

LEO satellites face new security risks

Regardless of their altitude or size, communications satellites transmit more power and therefore require more energy to jam than navigation satellites. However, low-Earth-orbiting satellites orbiting the Earth at altitudes of 2,000 kilometers or less switch frequently, which "results in delays and creates more interference" than large geostationary satellites, said Mark, professor of data protection and data protection. Mark Manulis said. Applied cryptography at the Cyber ​​Defense Institute (CODE) of the Bundeswehr University Munich.

Security and communications researchers have mostly studied defenses and countermeasures behind closed doors, but several publications and open-source research have revealed how unprepared many low-Earth orbit satellites are for a direct attack, and what defenses may be needed for future low-Earth orbit satellites.

For years, private companies and government agencies have been planning low-Earth orbit constellations, each with thousands of satellites. For example, the Department of Defense has been designing its own network of low-Earth orbit satellites to complement its more traditional geostationary constellation for more than a decade and has begun awarding contracts to build it. University research groups also launch miniature standardized CubeSats (CubeSats) into low Earth orbit for research and demonstration purposes. This proliferation of satellite constellations coincides with the emergence of off-the-shelf components and software-defined radio—both of which make the satellites more affordable, but perhaps less secure.

Russian defense authorities have commissioned a system called "Tobol" to counter jammers that could interfere with Russian satellites, journalist and author Bart Hendricks reports. This means that either Russia can deliver jamming signals to satellites, or it suspects that its adversaries can.

Many agencies and organizations launching the latest generation of low-cost satellites have yet to address the biggest safety issues they face, researchers write in the 2022 Low Earth Orbit Safety Report. This may be because one of the lures of low-Earth orbit is the relatively cheap ability of new hardware to handle smaller tasks.

"Satellites are getting smaller and smaller. Their purpose is very clear," said Ijaz Ahmad, a telecommunications security researcher at the VTT Technology Research Center in Espoo, Finland. “Less resources are devoted to computing power, processing, and storage.” Lower computing power means less encryption capabilities and a lower ability to detect and respond to outages or other proactive outages.

The rise of software-defined radio (SDR) is also making it easier to deploy hardware for new missions, including the ability of small satellites to cover multiple frequency bands. "When you make it programmable, you provide some kind of remote connection to that hardware so that you can program it. But if you ignore the security aspect, there are serious consequences," Ahmed said.

In today's fast-paced world, high-speed Internet and mobile services have become necessities rather than luxuries. But as data services continue to evolve and mature, requiring higher Internet speeds, and as operating systems need protection, hackers and adversaries continue to interfere. For some, this involves hacking into wireless connections in homes and offices for the purpose of extracting personal or business data.

But whether they're targeting government agencies, private companies, or individual users, these attackers typically use high-power signal jamming devices - wireless portable devices that block communication between devices. Such jammers are also a means of defense for users seeking to escape these attacks.

With this dichotomy in mind, former Khoury doctoral student Hai Nguyen and his advisor Guevara Noubir, both members of the Institute for Cybersecurity and Privacy at Khoury College, have pioneered a novel approach that can essentially eliminate these high-performance cellphone jammer in the event that traditional techniques fail. This failure occurs because traditional technologies are designed for non-malicious interference, require mechanical moving parts that are slow to respond to interference, or require additional radio frequency bands to achieve resilience. Their technique, known as JaX, can circumvent these scenarios.

"When you use wireless communication, you want to make it as robust and reliable as possible. As researchers, we like to solve difficult problems, and this problem has always been there, "Nubier said. "We want to approach this problem from a unique perspective, which is to develop secure communication technologies for GPS and Wi-Fi."

Nguyen and Noubir started working on this machine learning-driven idea about a year ago, when signal jamming played a major role in the Russia-Ukraine war. As they built up large amounts of synthetic data and collected experimental materials, their goal was to build a kind of black box that could be placed in front of the network and seamlessly protect users. The solution does not require complex machinery, thus simplifying the process of eliminating high-power signal gps jammer.

"For data collection, we set up a test bench, and for transmitters, we used software radios, and for jammers and receivers, we used other radios," explains Nubier. "We sent a legitimate signal, and then we also sent interference. We receive them through two antennas that store data, so we know what we are sending and what is interfering.

"The cool thing about our work," he added, "is that we can get an adversary's jammer to emit a more powerful signal than a legitimate one, and we can eliminate the interference as if it never existed!"

Nubier believes the paper's findings could be useful for a wide range of individual and organizational users who want to avoid malicious attacks on their data.

"The fact that we were able to achieve a very low bit error rate shows that we can outperform an adversary that can transmit a hundred times faster than a legitimate signal," he said. "There can be an extremely noisy signal in the environment, but because we have JaX, we can estimate what the gsm jammer is really transmitting, subtract it, and just leave the legitimate signal."

While this process sounds promising, the benefits only matter if the technology is logically sound and affordable - two barriers that often prevent innovative technologies from becoming ubiquitous. But Noubier believes he and Nguyen have cleared that hurdle, too.

"Our machine learning model is compact, so if you're designing any new system, you can easily incorporate it," he says. "Again, if the Department of Defense wanted to integrate JaX, the cost would be negligible compared to other models, and the model would be much more efficient."

Noubir and Nguyen, who recently defended their dissertation and joined Meta as a research scientist, acknowledge that new approaches to old problems always need tweaking and fixing. Still, they expect JaX to solve long-standing network problems and want to bring it to market.

UPDATE: A mobile man accused of interfering with emergency communications pleaded not guilty on Thursday, June 15, 2023. Trenton Lisak was charged with interfering with public safety communications and drug possession.

Prosecutors allege he used expensive, sophisticated equipment from an apartment in Ryan Park Towers. Mobile County 911 officials said communications in downtown Mobile were nearly paralyzed on June 6 and were disrupted the rest of the week.

The judge set a preliminary hearing for Lisak on July 19.

Ability:

Mobile, Alabama. (WALA) - Interference from expensive, “sophisticated” black market equipment disrupted police and emergency service transmissions for much of last week, according to law enforcement officials.

Police arrested Trenton Edward Lisak Saturday on a charge of interfering with public safety communications, a Class C felony punishable by one to 10 years in prison. He also faces drug charges. Prosecutors said the FBI is also investigating.

"This is an unusual charge," Mobile County District Attorney Keith Blackwood said Monday. "This is certainly something very serious. We need our law enforcement and first responders to be able to communicate, not just downtown but everywhere."

How unusual?

"This is a first for me," Blackwood said. "I don't recall any other case where this has happened - certainly not to this extent. That's a lot of equipment."

Lisak was arrested for theft, burglary, possession of a forged instrument and criminal mischief.

Mobile County District Judge Jennifer Wright set bail at $15,000, the recommended limit for the crime, and ordered 10 percent to be paid in cash. She also posted an additional $5,000 bond on the drug charge.

Additionally, the judge imposed a curfew between 8 p.m. 8 a.m. and ordered Lisak, 31, to stay away from the tower in Ryan Park downtown. Authorities said they found jammer device at the apartment complex that interfered with communications for all 57 law enforcement, fire and EMS agencies in the Mobile County Communications District.

That's also the home address listed on Lisak's booking information, but prosecutors told the judge investigators don't believe he lives there.

County Executive Robert Jackson described it as "very sophisticated cell phone jamming device placed in homes specifically designed to interfere with our frequencies."

Jackson added, "We actually had to modify our instrument to accommodate this."

911 system chief Charlie McNichol told Fox 10 News last week's outage effectively knocked out communications for a day.

"Last Tuesday this caused serious problems for the city centre," he said. "We actually have a tower site in Government Square. That's where the alarm came from. The first people who came here had serious communication problems."

Officials said it was unclear what the motive was. Blackwood said he had no idea what the defendant planned to do or where he obtained the equipment.

McNicholl said he didn't know if Lisak was just watching the chaos for fun, or if he was planning something more sinister and trying to disrupt communications as part of it.

"This individual was in possession of gps blocker that was purchased on the black market," he said. "It's illegal to even possess it. That's what's causing the problem."

WashingtonCNN — Russia has been hindering US-created mobile rockets more frequently in Ukraine recently, using electronic jammers to overthrow its GPS-based targeting system, this causes rockets to misfire their targets, multiple people who were involved with the project told CNN.

Ukrainian military officials have had to invent multiple different solutions to the problem of their own equipment, with the American help, they have employed the High Mobility Artillery Rocket System (HIMARS) as the most celebrated and feared piece of military hardware in Ukraine's conflict.

The medium-range rocket systems were touted as a significant game changer in the conflict, and have had a significant role in the past year since their arrival in Ukraine last summer, including in the offensive that led to the takeover of territory that was significant to Ukraine last year.

However, recent months have seen the systems become increasingly less effective as a result of the Russians' increasing blocking, five American, British and Ukrainian sources tell CNN that the HIMARS have been modified to counter the Russians' increasing jammer device.

It's a constant pursuit of a solution to the cell phone jamming, a Pentagon official said, only for the Russians to then reverse the solution. And it's not clear how long-term the game is sustainable.

With a large-scale Ukrainian offensive expected to begin soon, and the country's reliance on HIMARS, solutions are now more important to make sure Ukrainian soldiers can gain significant advantage.

It's still one thing to successfully oppose the Russians at their current location. Another goal for them is to drive out the Americans, the retired US Army Brig. said. Gen. Steven Anderson explained to CNN. They're sunk in, they've been there for a year.

Ukraine needs to keep HIMARS in the game

HIMARS has been of great importance, he said. They must have the capacity to preserve these HIMARS and utilize them to perform effective punches.

Ukraine has currently received 18 American HIMARS, and the U.S. has pledged to send 20 more. Other members of NATO have given 10 Multiple Launch Rocket Systems to the State Department, according to the Department of State.

The common proclamations from the Biden administration regarding hundreds of millions of dollars in military aid for Ukraine, including one on Wednesday, typically include HIMARS weapons, called GMLRs, as the most significant item. However, the exact number is not revealed.

The U.S. has also assisted the Ukrainians in locating the Russian jammers and destroying them, a “important priority” task, according to a concealed document in the Pentagon that was part of a volume allegedly leaked by Airman Jack Teixeira.

The document continues by advocating for the continued destruction of jammers as much as possible.

GPS jamming can adversely affect other "intelligent'' US weapons like the guided Excalibur artillery shells that are fired from Howitzers and the air-dropped bombs called JDAMs. The document with the leaked Pentagon described the JDAMS as being particularly vulnerable to the disruption.

A U.S. official acknowledged that the U.S. has advised the Ukrainians on how to recognize and destroy the Russian jammers, because there is only a limited number of ways to alter HIMARS and their rockets.
