NBC News reported that online retailers and drone technology companies are marketing radio frequency jammers as drone deterrence or privacy tools, bypassing laws that prohibit the sale of such devices in the United States.

The warning issued by the Federal Communications Commission (FCC) says signal jamming devices can block emergency calls and pose a serious risk to public safety communications, as well as interfere with other forms of daily communication and air navigation systems.

"The use of telephone jammers, GPS jammers, or other signal jamming devices designed to intentionally block, interfere with, or interfere with authorized radio communications violates federal law," the FCC said. "There are no exemptions for use in businesses, classrooms, homes or vehicles. Local law enforcement agencies do not have independent powers to use jamming devices; With certain limited exceptions, use by federal law enforcement agencies is authorized under applicable statute."

The FCC's warning also states that "it is illegal to advertise, sell, distribute, import, or otherwise market interfering devices to consumers in the United States."

But NBC reported that Amazon third-party sellers, independent online stores based in China, and small domestic companies specializing in drone-related equipment flouted the law. The FCC told NBC that it is investigating the sale of jammers, including on Amazon.

As part of its investigation, NBC interviewed the CEO of an American company that offers portable anti-drone RF jamming devices online. The CEO told NBC that the devices are easy for consumers to buy if they have the money, but they are mainly seeing interest from large corporations and government agencies as they prepare for domestic drone terrorism.

GPS technology has fundamentally altered the way companies oversee their vehicle fleets. Real-time tracking capabilities now enable managers to monitor their vehicles effectively, a crucial aspect for businesses heavily reliant on transportation. Fleet GPS tracking has significantly improved operational efficiency and speed for these companies.

Azuga's high-tech tracking system offers a plethora of benefits, ranging from optimized route planning to effective fuel management. However, the presence of fleet GPS jammers can hinder your fleet's progress. Let us delve further into the topic of GPS jammers and explore preventive measures to ensure uninterrupted fleet operations.

What are Fleet GPS Jammers?

Concealing their whereabouts is made possible for drivers through the use of GPS jammers, which are small transmitter devices. These jammers operate by emitting radio signals on the same frequency as your fleet GPS device, resulting in interference that disrupts the GPS device's ability to track the vehicles' locations. Despite being illegal, the convenience of GPS signal jammers leads to many drivers disregarding the law and utilizing them.

How Do GPS Jammers Work?

A GPS jammer disrupts standard GPS signals. This disruption makes it difficult for devices to determine their location accurately. A driver can activate a GPS jammer with three easy steps:

1. They plug the jammer into the auxiliary power outlet.
2. The driver then places the unit near the fleet GPS tracker.
3. When the driver activates the jammer, it creates an interference signal that lasts over a 5-10 meter radius of the fleet GPS signal.

Of course, you want to prevent your fleet drivers from using GPS jammers. Not only are they bad for your business, but they can also have serious consequences. They are illegal because they interfere with essential services like navigation and emergency communications.

Three Tips to Combat GPS Jammers

• Tip #1: Privacy Mode Authorization
• Some authorized drivers use their work vehicle for personal tasks, like taking it home or running errands during lunch breaks. In these situations, they might prefer not to be tracked. GPS tracking devices often have a "privacy mode" feature, allowing drivers and dispatchers to hide their location and activity temporarily. This feature helps protect their privacy without resorting to using GPS jammers.
• Tip #2: Jamming Detection for Added Security
• Advanced GPS tracking devices, like Azuga's Fleet tracking software, can detect GPS signal jamming. This feature safeguards against vehicle theft and aids in recovering stolen fleet vehicles.
• Tip #3: Tracking Employees Using GPS Blockers
• Even without jamming detection, you can still catch employees using GPS blockers. When an employee activates a GPS blocker, it shows as a missing or interrupted trip on the tracking map. Additionally, you can set up alerts for GPS signal errors to notify management when interference occurs. Using a blocker would likely draw more attention to their actions.

Glendale police issue warning about burglars using WiFi signal jammers to disable alarms, security cameras

GLENDALE, Calif. (KABC) -- Glendale police have issued a warning about residential burglars who use WIFI jammers to disable security alarms and surveillance cameras.

As described by police Sgt. Victor Jackson, the devices used by thieves block the signal or scramble the WiFi. "So if you have a Ring camera, a Nest camera -- any kind of alarm system that is WiFi-based or a camera that's WiFi-based -- it blocks the signal and knocks it out," he said.

A disproportionate surge in residential burglaries plagued Glendale and Southern California in the fall, leading investigators to the crime trend.

"As our detectives started going into these cases, that's when they realized what was happening," Jackson said. "In some cases, because of the way the device works, it made it look like when you went back and rewound your tape and looked, it wasn't a black screen -- it was seamless. It didn't exist there, so there was no evidence."

Police recommend that residents increase security by:

• hardwiring alarm systems and cameras,
• using back-up batteries in those security devices,
• installing sturdy locks on security gates,
• enhancing exterior lighting,
• securing windows and balconies,
• and having a trusted neighbor or housesitter look after your home, when away.

The Glendale Police Department's residential burglary task force has been working to lower the number of break-ins, officials said.

"Our patrol officers, our motor officers, our special enforcement detail, and detectives -- we have them undercover in the area -- and we saturated the area," Jackson said.

Nora Alabi, a Glendale resident, told ABC7: "I feel like there's no part of the city that you can be in and not run into a cop or not run into a police car.

"If I stand here for five minutes, I might see like three cop cars drive by," she said. "So, because of that, I feel like it's a safe city."

In a statement by the Los Angeles Police Department, officers warn that a group in Wilshire is using wifi jamming technology to disarm surveillance cameras and alarm systems that rely on Wi-Fi.

(TNS) — A group of thieves have been outsmarting smart devices across the Los Angeles area, authorities said.

In a March 4 statement by the Los Angeles Police Department, officers warn that a group in Wilshire is using Wi-Fi jamming technology to disarm surveillance cameras and alarm systems that rely on Wi-Fi.

This swarm of tech-savvy robberies in California is part of a larger “smart” crime wave happening nationwide. Last year, police in Minnesota and Connecticut issued similar warnings to residents when groups of Wi-Fi jamming thieves made their rounds. And those are just two examples of many.

While the Federal Communications Commission has banned Wi-Fi jamming devices, this doesn’t stop criminals from buying them cheaply, KARE11 reported. Wi-Fi jamming devices don’t necessarily deactivate devices, but work by overloading the network the devices are connected to.

“These (signal jamming) devices create traffic jams for the radio transmitter so that real traffic cannot get through,” cybersecurity expert Mark Lanterman told the outlet.

“If you are going to use a Wi-Fi camera for your front door, perhaps consider using a hardline camera inside your home,” he said. Wired cameras connected via Ethernet cables do not rely on Wi-Fi networks and would not be disrupted by a Wi-Fi jammer.

Los Angeles police also recommends hard wiring burglary alarm systems

While “smart” technology may be part of the problem, it may also have a hand in the solution, according to Tom’s Hardware. Officials recommend using timers or smart home devices to make it look like someone is home while you are away. Some smart home technology also comes with the ability to alert users if the signal or connection has been interrupted.

Tom’s Hardware also recommends connecting surveillance devices that store camera footage directly on your device, and not just to a cloud storage system. By having a camera that records to itself, you’ll have footage saved during a Wi-Fi disruption.

The LAPD also encourages people to stay vigilant by locking their doors, relying on neighbors to check on things when away and reporting any strange activity, including suspicious vehicles with temporary or dealer plates.

Jammers don't target individual phones - they actually block all phones in the affected area. They drown out communications between cell phones and base stations by generating RF noise - the equivalent of you trying to talk to someone while I'm standing next to you screaming at the top of my voice.

I doubt anyone is using jammers - jammers are uncommon, and the penalties for using jammers are quite severe in many places. Start by talking to your mobile carrier. If after all of this you still have reason to believe that jammers are being used, complain to the body responsible for radio and communication systems in your country - this could be the FCC in the US, or Ofcom in the UK - other countries will have their own equivalent.

Someone used a signal jammer on me. How do I find it and stop it?

I thought it was the same at my house where the signal was always down to 3g and I couldn't use the service unless I was outside. It turned out to be an IMSI trap installed in the apartment next door. I started getting phishing pages from my bank and realized that my email had been compromised, the virus software on my computer had been disabled, and everything I did had been copied because it acted as MITM.

How to prevent jammers?

This happened to me at the school where I worked. Now, a private company has rented the school building to conduct the exams. As previously agreed, in order to prevent rampant unfair practices in public exams, the company installed jammers in all 108 classrooms of our school. This was done a few days before the exam. Children are curious and mischievous by nature. One morning, we found that none of our smartphones on or off campus had received a signal. Several departments at a university next door were also affected. It's almost impossible for us to find the malicious jammer we suspect is at work. Fortunately, however, the school LAN as well as Internet connections and landlines are working. As head of technology, I had to come up with a solution, and today I'm going to share that solution.

Compared to GSM 4G cellular networks, Wifi uses a higher frequency (2.4 Ghz). The trick for all users with a phone that supports WiFi calling or VoIP is to route calls through the WiFi network. For other users with smartphones, the solution is to use Whatsapp to talk to FBM (Skype works too, only no one uses it except me).

This went on for a few days, and after the test was over, the renters left with their jammers.

Have you ever secretly used a cell phone blocker in a restaurant, theater, or on public transportation to end an unusually loud, obnoxious, and unnecessary phone conversation with a stranger sitting next to you?

I once rode the quiet Amtrak car between Boston and New York.

A woman was on the phone, completely oblivious to the signs posted and the announcements made over the public address system.

She replied, "The train hasn't moved yet," and continued the conversation.

From now on, all I have to do is ask the conductor for help, even if he's sitting next to me. I've gotten too many smart-aleck - or worse - replies.

Once, at a movie, I asked a young woman next to me to turn off her lit cell phone, and she reported me for harassment.

God, I'm easily twice her age, but that obviously doesn't count.

How to use cell phone jammer? Where can I buy one?

To use this phone number, first make sure you have the lawyer's phone number on hand - it is illegal to use a lawyer's phone number in most countries.

It's easy to find them online - try Google, but you'll have to check if they're allowed to be imported into your country. It's easy to find unsophisticated devices that broadcast across the entire spectrum (kind of like sparks, but more sophisticated), but this would obviously annoy more people and authorities even more, not least because it would block 911 calls and potentially also communications for emergency services, WiFi, Bluetooth, etc.

If you want a device that allows 911 calls but blocks other calls, it's very complicated and expensive. In addition, as more and more frequencies (from about 800Mhz to more than 3GHz) are used in cellular networks, these devices must cover a range of radio spectrum.

Prior to midday on September 11, 2018, Jared Johns, a former Army private, positioned himself on his bed, activated the camera on his iPhone, and bid farewell to his loved ones.

As the two-minute video neared its conclusion, Johns's eyes grew wide upon reading a message on his screen: "She is heading to the authorities, and you will be incarcerated," the message stated.

Johns, a veteran of the Afghanistan conflict, inhaled deeply before positioning a 9 mm handgun beneath his chin and squeezing the trigger.

A large number of ex and current military personnel, including a 24-year-old veteran, have fallen victim to a malicious scheme known as "sextortion." This tragic plot, which resulted in the young veteran's suicide, involved deceitful individuals pretending to be underage girls on dating platforms. These scam artists then tried to extort money from men who fell into their trap, according to prosecutors.

However, the most surprising element of the storyline in Johns' situation was that it was reportedly executed by prisoners at Lee Correctional Institution, a high-security prison located in South Carolina approximately 150 miles east of Greenville. Moreover, the inmates managed to accomplish this using smartphones - prohibited gadgets that were supposed to be prevented by the prison's $1.7 million "managed access system."

Prison authorities, along with certain federal organizations, are considering acquiring a more advanced and possibly pricier technology to prevent illegal cellular and Wi-Fi communication from contraband phones in correctional facilities: a signal blocker device capable of blocking all calls within its designated area.

Bryan P. Stirling, the director of the South Carolina Department of Corrections, has emphasized that inmates may be physically incarcerated, but they still have digital freedom.

However, certain individuals with expertise caution against the use of jamming technology, as demonstrated by the recent testing conducted by the federal Bureau of Prisons in a South Carolina correctional facility. They argue that such technology may jeopardize public safety by disrupting emergency 911 calls and other cellphone services in close proximity. In the case of rural prisons, the worry extends to drivers on local roads and highways. Furthermore, these experts assert that the effectiveness of this technology is highly doubtful.

Jamming all calls, even to 911

The utilization of cellphone jammers, a technology that has long been opposed by the communications industry, has been proposed by corrections officials and federal agencies to address the issues at hand. These problems highlight the need for such measures, as they aim to prevent all calls, including those made from phones owned by staff or emergency workers.

Managed access systems enable individuals to place calls only if their numbers are pre-approved, whereas jammers have the capability to disrupt all frequencies, including data and Wi-Fi, without discrimination. This poses a significant challenge for the country's 911 phone system, as it operates on a frequency similar to that of commercial carriers.

Solely federal agencies have the legal authority to utilize jammers, under specific conditions related to national security. However, with the approval of FCC Chairman Ajit Pai, who was appointed by President Trump in 2017, and the U.S. Department of Justice, the use of jammers in prisons may be permitted.

During the month of September, announcements were made by the department and state officials regarding a test conducted at South Carolina's Broad River Correctional Institution. The test revealed that a micro-jammer had the capability to block calls within a cell block, while still permitting "legitimate calls" just one foot outside the walls.

However, the technical report conducted by the National Telecommunications and Information Administration presented a different perspective. It highlighted that the test solely focused on one out of the 14 jammers necessary to obstruct calls in half of the cellblock. Additionally, the report indicated that jamming was detected at a minimum distance of 65 feet, although the extent of its impact on regular cell-phone service remained uncertain.

A Chinese government-affiliated trade body sought to purchase drone-jamming equipment for Russian buyers, but dismissed accusations, claiming the Russians tried to buy children’s toys, FT says.

FT: China trade promotion body eyed drone jammers for Russia

China’s Guangdong Province Trade Promotion Association for Russia, established under the guidance of the provincial commerce department, posted a “Notice of foreign enterprises purchasing [unmanned aerial vehicle] equipment” on its WeChat social media site, seeking “interference generators, drone detectors (trade names BorisTone, Assel Labs, Bulat) or other similar technological solutions, UAV suppressors, communication frequency band signal blockers,” according to Financial Times.

China claims neutrality in the Russo-Ukrainian war, positioning itself as an alleged proponent of peace. Despite this, it provides economic support to Russia, including drone technology and gunpowder ingredients, following the announcement of their “no limits” relationship.

FT notes that the agency was set up last year to help Russian customers buy goods ranging from trucks to boats. This time, the buyers specifically wanted a locally produced equivalent to the Bulat drone detectors developed by the St. Petersburg company 3mx, which has said its products have been used “on the front lines” during Russia’s invasion of Ukraine.

The procurement notice was later removed from the association’s WeChat account. When contacted by the Financial Times, a person from the group claimed it was “some sort of mistake” and alleged the Russian buyers were actually looking for “children’s toys,” contradicting the detailed drone countermeasure descriptions in the original post.

The US aims to disrupt supplies to Russia’s defense industry via China, a crucial support route for Putin’s war efforts. US Deputy Treasury Secretary Wally Adeyemo emphasized in Berlin on 31 May that Chinese firms must choose between trading with Western economies or supplying Russia with dual-use goods.

The Financial Times report highlights the dominant role China plays in the global drone supply chain through companies like DJI, the world’s largest commercial drone maker.

Earlier, British Defense Minister Grant Schapps stated that forthcoming evidence from American and British intelligence would show China providing lethal combat equipment to Russia for use in Ukraine. However, US National Security Adviser Jake Sullivan dismissed Shapps’ claims, noting at a White House press briefing that the US has not observed such activities and he anticipates coordinating with the UK for a unified understanding.

The FCC says illegal devices that block cell phone signals could pose a security risk.

The FCC has noticed a rise in people selling "jammers." The devices can block cell phone calls, text messages, Wi-Fi networks and GPS systems and could be used to cause chaos in public places.

The small, battery-powered devices can be used to create "blind spots" in a small area (usually about 30 feet) and have been used by movie theaters, restaurants and schools to prevent people from using their phones. But they can also cut off 911 calls, interfere with navigation near airports and have been used to jam radio communications near police stations. FCC officials say they have noticed an increase in the flow of jammers, which are banned by federal law, into the U.S. Many of the cheaper versions, which sell for as little as $25, are imported from Asia, according to the agency.

It is illegal to sell, advertise, use or import jammers under the Communications Act of 1934, which prohibits blocking radio communications in public.

Earlier this week, the FCC issued subpoenas to eight individuals and companies that posted ads for jammers on Craigslist.

The FCC said cities including Orlando, Philadelphia, Austin, Mississippi, Charlotte, North Carolina, Washington, D.C., Cincinnati and Corpus Christi, Texas, advertised jammers on the site. Officials said they do not believe the cases are related.

"Simply posting an ad for a signal jammers on a site like Craigslist.org is a violation of federal law. Signal jammers are contraband for a reason," Michele Ellison, director of the FCC's enforcement bureau, said in a statement. "One person's moment of peace or privacy could jeopardize the safety and well-being of others."

According to the citations, most sellers advertised the jammers as a way to take an "undisturbed nap" on the bus, quiet a classroom or keep your area "free of interference," without mentioning the more nefarious uses the devices could be used for.

"We are increasingly concerned that individual consumers operating jammer devices do not appear to understand the serious consequences of using jammers," one of the citations read. "Instead, these operators mistakenly believed that their illegal operations were a matter of personal convenience or should be excused."

But the FCC said at least one seller appeared to know that jammers were contraband.

Keith Grabowski allegedly advertised on Philadelphia Craigslist for sale a "cell phone blocker, wifi blocker" for $300. In his ad, he said that "due to the nature of this item, we are revealing very few details," that the jammer was "not a toy," and that "I just wanted to get rid of it as quickly as possible."

"The nature of the ad suggests that Mr. Grabowski knew about the sensitive and/or illegal nature of the equipment he was selling on Craigslist," the citation reads.

People who receive the ticket have 15 days to remove the ad from the site and provide the FCC with information about where the jammer was purchased and to whom it was sold. Simply posting an ad for the sale of a jammer could result in a fine of more than $100,000.

The FCC has set up a "jammer tip line" for people to report to the agency people who may be selling or using jammers.

"We intend to take increasingly tough enforcement action against offenders," Ellison said. "If we find you selling or operating a jammer, you will be punished."

Expanding the scope of cell phone jammer applications

Cell phone jammers were initially created for law enforcement to intercept messages from terrorists and criminals. Over time, they have undergone significant advancements. Nowadays, they play a crucial role not only in combating terrorism but also in various official and civilian applications. Their capability to block communications as a precautionary step against organized crime and to disable remote-controlled explosive devices makes them essential in contemporary security measures. Furthermore, there have been instances where signal jammers have prevented attempts to assassinate prominent figures, underscoring their vital function in high-risk security situations.

Technological advances enhance jamming capabilities

The efficiency of cell phone jammers is attributed to the sophisticated technology powering them. These gadgets emit precise signals that disrupt the functioning of the remote-controlled receiver, thus thwarting the implementation of any programmed instructions. It is crucial to note that this interference is limited to a specified zone, guaranteeing that devices beyond this shielded region remain unaffected. This accuracy is vital for upholding uninterrupted communication across a broader expanse while safeguarding the intended area.

Jammers employ uniquely coded signals to trick GSM device receivers, stopping mobile phones from linking up with their respective base stations. This advanced method guarantees that any effort to communicate through a cell phone within the jammed area is successfully disrupted, while authorized communications beyond the jammed area continue without interruption.

Applications Beyond Terrorism

1. Educational Institutions:
   - Cell phone jammers are increasingly used in educational institutions to prevent cheating in exams. By blocking signals within exam rooms, authorities can ensure a fair exam environment.
2. Prisons and Detention Centers:
   - In detention centers, jammers are essential to prevent inmates from making unauthorized calls, which could coordinate criminal activity outside the facility.
3. Corporate Security:
   - Companies use jammers to protect sensitive information during high-level meetings, ensuring that no unauthorized recording or transmission occurs.
4. Public Events and Venues:
   - During large public events such as concerts or sporting events, jammers can prevent disruptions and ensure the safety of attendees by blocking potential threats such as remote control devices.
5. Hospitals:
   - In medical settings, jammers help maintain security in areas where cell phone signals could interfere with sensitive medical equipment.

It is evident that cell phone jammers offer numerous advantages; however, their utilization necessitates a careful balance between ethical and legal factors. The deployment of jammers is subject to regulations that differ across countries and regions. In numerous locations, their usage is restricted to authorized individuals and specific situations to prevent any potential abuse and guarantee uninterrupted access to emergency communications.

With the continuous advancement of technology, it is expected that cell phone jammers will undergo further improvements. These future enhancements may involve refining the targeting capabilities to minimize any unintended disruptions, enhancing the portability for quick deployment in dynamic scenarios, and strengthening the encryption to ensure that jamming signals remain impenetrable.

Cell phone jammers have transformed from a niche law enforcement tool to a versatile device with widespread use in security, privacy, and public safety. By leveraging advanced technology, these devices play a vital role in protecting against threats ranging from terrorism to cheating on exams. However, their use must be strictly regulated to balance security needs with individual rights and freedoms. As we move forward, the continued development of jamming technology promises to enhance our ability to protect and secure society from emerging challenges.

Dissatisfaction plays a vital role in the advancement of individuals, societies, and human civilization. While an excess of discontent can be detrimental, a moderate amount of dissatisfaction can prove to be advantageous. If everyone is content with their circumstances, there will be no impetus for progress, ultimately resulting in the regression of humanity. Today, we will discuss the importance of discontent in the innovation of cell phone signal jammers.

The fundamental role of a cell phone jammers is to prevent unauthorized communication signals from being transmitted when required. This device is especially beneficial for individuals working within government and correctional institutions. Nevertheless, it is crucial to acknowledge that signal jammers can potentially disrupt communications, thereby posing a substantial security concern.

The necessity for security in certain facilities is evident. A prime example is military establishments that strictly prohibit any form of communication without prior approval.

Cell phones play an important role in our daily life. Why are there cell phone blockers now? Dissatisfaction is dissatisfaction, dissatisfaction with the improper use of mobile phones in some formal occasions. Discontent is also a driving force of human civilization as a whole. It can be said that in primitive society, science came into being because ancestors were not satisfied with their understanding of the world, and technology came into being because ancestors were not satisfied with simple manual labor. This curiosity and desire, in fact, also led to the prosperity of technology later.

Use jammers to prevent interference and block unauthorized communications

To maintain uninterrupted communication, the use of a signal jammersis necessary to enhance your lifestyle. Many countries have restrictions on the personal use of cell phone jammers. It is advisable to familiarize yourself with the laws in your region. Some individuals resort to installing jammers, particularly cell phone jammers, to prevent signal interference. If permitted by the laws of your country, you can obtain a valuable jamming device.

Whether it occurs during a class, conference, presentation, or religious gathering, an untimely phone call can cause considerable disturbances. To address this issue, the utilization of cell phone signal jammers can effectively prevent such interruptions. By employing these devices, interference and unwanted calls can be blocked, granting you the authority to maintain a peaceful environment.

Have you faced this situation previously? The phone continued to ring, but no one paid attention to the disruption. You exclaimed, "Please switch off your phone." Regrettably, your plea went unheeded. In any sizable crowd, instructing people to silence their devices simply doesn't suffice. There will always be a significant number who opt to keep their phones on for one reason or another. The solution lies in a cell phone jammer.

The question of whether this indicates a more significant societal concern can be subject to discussion, but the fact remains unchanged. Even during funerals, it is inevitable that occasional phone calls will interrupt the silence or be made for prayer.

Regardless of the scenario, the signal jammer can obstruct the necessary frequency for the phone to receive calls, ultimately preventing the phone from ringing.
