Utilized extensively worldwide, the GPS satellite positioning system is the most prevalent satellite positioning system. It facilitates vehicle tracking, route navigation, information inquiry, traffic command, emergency assistance, and other essential functions. Although the GPS satellite positioning system has greatly enhanced convenience in our daily lives, it has also introduced certain issues that can jeopardize individual safety.

To illustrate, in the case of a mortgage car company, they temporarily assume control of the car by providing financial assistance to the original owner. In order to prevent any covert retrieval of the vehicle by the original owner, these companies invest in GPS shields. These shields are installed both in the vehicle's parking lot and on the car itself, effectively preventing the original owner from locating the vehicle and thus ensuring the safety of the property.

As the GPS locator market expands, there is a growing interest in GPS signal blockers among those who wish to evade GPS signal tracking. However, it is crucial to ascertain whether the GPS signal blockers currently available in the market are capable of effectively shielding signal tracking.

Most GPS locators can be effectively shielded by gps blocker. The use of blockers disrupts the normal functioning of the GPS locator, preventing complete data transmission to the locator monitoring platform. Similar to mobile phones, GPS locators require the insertion of a mobile phone card or an Internet of Things card to retrieve data. Therefore, as long as the GPS signal blocker can obstruct the signal transmission of the mobile phone card, it can also block the GPS locator.

What to Do if Authorized Communication is Being Jammed

Do you suspect that a signal jammers may be causing interference? Bad network connections can be caused by a variety of factors including:

• faulty equipment


• physical obstructions that block the signal



Before filing an interference complaint via the FCC Consumer Complaint Center, you should troubleshoot equipment and connectivity issues in accordance with manufacturer and service provider recommendations. In addition to consulting your owner’s manual and the company’s tech support, searching the Internet for your device/model and specific issue may help to either identify or rule out possible causes.






Cell Phone Jamming is Prohibited in the USA




Like many countries, the United States prohibits the employment of mobile signal jammer in practically every use case.




According to the Federal Communications Commission, “Federal law prohibits the operation, marketing, or sale of any type of jamming equipment that interferes with authorized radio communications, including cellular and Personal Communication Services (PCS), police radar, and Global Positioning Systems (GPS).”




It is also illegal to sell, distribute, advertise, import, or market jamming devices to consumers in the United States. The use or marketing of a jammer in the U.S. may subject a person to:





1. significant monetary penalties (fines of up to $11,000)


2. seizure of the unlawful equipment


3. criminal sanctions including imprisonment



There are no exemptions for use within a residence, business, vehicle, or classroom. Local law enforcement agencies do not have independent authority to use jamming equipment. Jamming equipment employment by federal law enforcement agencies is authorized in accordance with applicable statutes only in certain limited exceptions.




Though signal jamming is prohibited, cell phone detectors are legal in the United States.




Cell Phone Jammers – 3 Reasons Why They’re Illegal




Cell phone jammers can prevent you and other persons from making 911 and other emergency calls. They can also create dangerous risks to public safety communications in addition to interfering with other forms of daily communication.

Once more, state prosecutors from different parts of the country are calling on Congress to pass a law that permits state prisons to block cellphone signals used by incarcerated individuals. These prosecutors argue that these devices enable prisoners to orchestrate violent acts and engage in criminal behavior.

In a letter addressed to House Speaker Kevin McCarthy and Senate Majority Leader Chuck Schumer, a group of 22 Republican prosecutors, headed by South Carolina Attorney General Alan Wilson, expressed their plea for Congress to pass legislation. This legislation would empower states to implement a cell phone jamming system, aiming to protect inmates, guards, and the wider public.

Wilson's office has announced their intention to engage with Democratic state prosecutors, asserting that the issue is not a partisan matter.

A letter, provided to The Associated Press, has been brought forward by the attorneys. This letter outlines a number of criminal incidents that the attorneys claim were coordinated by prisoners using contraband cellphones. These incidents include a drug conspiracy in Tennessee and a double homicide that was reportedly ordered by an inmate from Indiana.

Furthermore, they made mention of a siege in 2018 that was connected to gang activity and took place at a prison in South Carolina. This violent incident persisted for more than seven hours and claimed the lives of seven inmates. A harrowing description provided by one prisoner depicted the grim sight of bodies literally stacked on top of each other, resembling a morbid pile of wood. The authorities responsible for corrections attributed the orchestrated violence, which stands as the most severe prison riot in the past 25 years in the United States, partially to the use of illegal cellphones.

According to the prosecutors, the prohibition of contraband cell phones among inmates would act as a deterrent against the escalation of drug trafficking, violent riots, and other criminal offenses.

In order to render the phones worthless, which are often smuggled into state prisons through various means like hiding them inside hollowed-out footballs, corrupt employees facilitating their entry, and even dropping them using drones, prosecutors are urging for a revision in a federal communications law that has been in place for almost a century. This revision would allow state prisons to utilize jamming signal technology to neutralize illegal cell signals.

For years, there has been a continuous drive to combat the presence of illicit cellphones in state prisons. South Carolina Corrections Director Bryan Stirling has emerged as a prominent figure in this effort, rallying corrections directors nationwide to advocate for enhanced technological measures to effectively tackle the issue of contraband phones.

A notable accomplishment was attained in 2021, as the Federal Communications Commission adopted a ruling permitting state prison systems to request licenses to identify and deactivate illegal cell signals, one at a time, in collaboration with cellphone providers. South Carolina took the lead by submitting an application to utilize this technology, but according to Stirling's statement to AP on Tuesday, no action has been taken on the state's application.

According to Stirling, federal prisons have the legal authority to interfere with cell signals within their premises, but as of now, they have opted not to employ this practice.

The wireless industry group known as CTIA opposes the implementation of jamming technology, as it believes it could hinder legal phone calls. However, in a 2020 document from the FCC, CTIA informed the commission that it has been collaborating effectively with its member companies to cease service to illegal devices as directed by court orders they have obtained.

Calling combating contraband phones “a serious issue,” CTIA officials said in a statement to the AP that the “wireless industry remains committed to working with corrections officials and policymakers at all levels of government to implement effective solutions that combat contraband phones while protecting lawful communications.”

A prompt seeking comment on the renewed push for jamming has been sent via email, but the FCC officials have not yet issued a response.

Previously, Congress has deliberated on the subject of jamming legislation, yet no bills have been approved or even given the opportunity for a hearing. U.S. Senator Tom Cotton, representing Arkansas and belonging to the Republican party, reintroduced a similar measure in August during the previous Congress.

“We’re not going to stop advocating,” Wilson told AP on Tuesday. “I can only hope that at some point, Congress is going to take note.”

As the exam date approaches, the prevalence of 5G signal jammers has significantly increased. These jammers are being actively endorsed and utilized, especially in prominent educational institutions where exam mobile phone jammer are visibly present in examination halls. The growing installation of this equipment in schools raises the inquiry: what motivates this trend?

Mariam Aly, a faculty member at Columbia University, has exhaustively explored different approaches to discourage academic dishonesty among her students. In her cognitive neuroscience class, she allows her students a full week to complete an open-book examination. Moreover, as a component of this examination, the nearly 180 students in the class are required to affix their signatures to an honor code.

Nevertheless, cheating continues to occur. Dealing with student misconduct, she asserts that it is the most arduous aspect of her job. Aly emphasizes, "It creates an uncomfortable and distressing situation for everyone involved." She goes on to say, "It is truly challenging to hold them solely accountable. One cannot help but experience a sense of disappointment and frustration."

She acknowledges that her students are currently dealing with unprecedented levels of stress and uncertainty. She understands their plight, having never encountered a pandemic during her own school years.

The rise in popularity of something is directly proportional to the demand it garners. This correlation can be attributed to the escalating issue of cheating, which has become increasingly common in recent years, accompanied by the frequent emergence of daunting cheating methods.

In order to tackle the problem effectively, a particular kind of shielding equipment is employed within the examination room to combat cheating resulting from electronic signals. The utilization of this equipment proves highly advantageous for numerous examinations, resulting in a growing preference among individuals to employ it as a preventive measure against cheating.

The exam signal blocker in question is designed to effectively impede the communication signals of 5G mobile phones, while also proficiently obstructing 2.4G and 5.8G WIFI signals. As a result, individuals using mobile phones or certain electronic products will find themselves unable to send or receive signals within the range covered by this shielding mechanism.

No matter the product, only this guarantee can ensure fairness for individuals facing difficulties in their exams, and this exam signal jammer operates silently and without any noise. This shielding method poses no harm to the human body, enabling candidates to take the exam with a peaceful state of mind.

The utilization of cellular phone jammers is commonly regarded as illegal by the FCC, primarily because it hampers the communication capabilities of emergency personnel who heavily depend on the same frequency as cell phones for their crucial communications, as well as their own use of mobile phones.Nonetheless, the promotion of signal jammers by correctional facilities, schools, and local governments has gained momentum. The objective behind this initiative is to combat cheating in classrooms, enhance the focus of taxi drivers and limousine chauffeurs while driving, and prevent prisoners from accessing contraband cell phones.

Wave Bubble Cell Phone Jammers

The use of cell phone jammers is against the law, leaving individuals with two options: obtaining them illegally from overseas or constructing them unlawfully at home. This requires a considerable level of expertise in working with chips and antennae. One noteworthy example is the Wave Bubble Jammer, which has the ability to interfere with radio frequencies beyond those used by cell phones.To ensure power supply, it is necessary to install a lithium-ion battery, which can deliver a jamming duration of up to two to four hours, depending on the frequencies present nearby. Recharging can be done through a USB connector or a common 4 mm DC jack. Alternatively, AAA batteries can be employed.

Within a twenty to twenty-five foot radius, the microchips in the jammer have two antennae that capture various frequencies.The successful installation of the designated chips, crucial for the functionality of this device, demands a substantial amount of intricate SMT soldering. This includes multiple TSSOP and SOT chips, 0603 RC's, as well as obscure parts. Additionally, the proper construction and debugging of the device require specific equipment.Due to the device's illegality within the United States, the specific sources for these are not obtainable.

Cell Phones Modified to Jammers

A number of cell phone jammer have been adapted from obsolete cell phones to function on the same frequency as the targeted cell phone, emitting a tone that renders any phone conversation unfeasible. It is important to emphasize that these jammers are illegal and pose a challenge to construct without adequate knowledge and skill in soldering microchips and manipulating radio frequencies.The operation of police CB radios mirrors that of cell phone jammers, as both devices are capable of detecting and picking up all frequencies within their proximity, facilitating communication over the CB. Nevertheless, cell phone jammers take it a step further by blocking transmissions.

The prevalence of a significant quantity of malicious wireless devices, which have the sole purpose of intentionally interfering with wireless networks, is a matter of great concern. Although their procurement is clearly against the law, these devices can now be conveniently purchased online at a moderate price.

The functionality of these jammers is based on the following principle: they emit a robust wireless signal that interferes with the physical layer of the wireless communication protocol employed. As a result, they possess the ability to disrupt protocols operating at different frequency bands. Their primary influence is exerted on the medium, which constitutes the first layer of the OSI stack.As a result, any higher-level communication protocols will suffer the consequences. This includes Wifi, bluetooth, 3G, 4G, GSM, GPS, and various other forms of communication. It can be compared to an erratic individual who suddenly starts shouting in the midst of a conversation. Whether the speakers are conversing in English or Russian, they will no longer be able to effectively communicate with each other.

After the new wipe that made its way into Escape from tarkov on 28th December, players have been trying to grind in the game and have been completing quests given by traders to reap rewards, experience points, and reputation. Broadcast - Part 1 Quest is the starting point for a series of quests under trader Sergey Arsenyevich Samoylov, known by his alias "Mechanic." Once you finish this quest, you will have the opportunity to finish the other Broadcast quests and also do other ones offered by Mechanic. This particular quest happens on Lighthouse, the eighth location that was added to the game.

When you take up this quest from the Mechanic, he says that he does not really understand anything in life and that he heard something about a live broadcast in the city somewhere. He adds, “They say that someone is performing surgeries and filming it on their camera. I'd understand if it was an actually good willed doctor helping people. I would even understand if there was an organ trade, although that in itself is disgusting. But tell me, why stream this? Is this a kink for some perverted oligarchs? I honestly don't have an answer. But I do know that this broadcast must be shut down. Can you put a cell phone blocker near them?”

The Broadcast - Part 1 quest objectives are:

• Locate the hidden recording studio on Lighthouse


• Place a Signal Jammer inside the studio

For this task, you will need the Operating Room key. This can be found in the pockets and bags of Scavs as well as in jackets. However, that being said, it is a rare key. It can sometimes also be bought from the flea market.

Firstly, you will have to go to the Water Treatment Plant on Lighthouse for this quest and enter Building 1. Your PMC will start just outside Building 1 and as you enter it, you will have to hug the right-side wall and walk all the way straight till you find a door. This door leads you to the Operating Room where you will use the key.

Once you enter the room, you will immediately be prompted to plant the signal jammers anywhere in the room. It is a 10-second timer and if you happen to die while planting, you will have to start from scratch. However, the good news is, if you successfully plant the jammer, the Broadcast - Part 1 quest will get auto completed and you will not have to survive an extract from the raid.

Wi-Fi jammers: The tool of choice for criminals

The use of Wi-Fi jammers in burglaries is on the rise, indicating a growing trend among burglars. To counteract this, the police have taken proactive measures by securing arrest warrants to thoroughly investigate and apprehend those involved.Exploiting vulnerabilities present in wireless networks, thieves and criminal organizations are capitalizing on these weaknesses, while law enforcement agencies are actively pursuing these criminals by means of arrest warrants. By employing signal jammers, these perpetrators can effectively disable security systems and surveillance cameras, enabling them to clandestinely infiltrate homes without raising any red flags for the police.

Exploit wireless network vulnerabilities

Due to the extensive adoption of wireless networks in residential settings, perpetrators and criminal syndicates have discovered an alternative method to perpetrate illegal actions without legal permission. Exploiting the dependence of numerous home security systems and cameras on Wi-Fi connections for communication and surveillance, thieves take advantage of this vulnerability.This legal loophole was cleverly employed by the crew to evade the requirement of a search warrant. By utilizing Wi-Fi jammers, thieves can effectively disrupt these connections, rendering security measures useless without proper authorization.

Disable security systems and cameras

The presence of Wi-Fi interference raises apprehension as it allows thieves to tamper with the signals that security systems and cameras heavily depend on. By disabling these devices, criminals can carry out their illicit actions without the worry of being recorded or triggering any alarms.

By employing this technique, they gain a significant upper hand as they can enter the residence without alerting anyone or leaving any incriminating evidence, even in the absence of a search warrant. Moreover, it affords them a greater window of opportunity to act before authorities or homeowners become aware of the intrusion, without requiring a warrant.

The mechanism of Wi-Fi interference

Jamming wireless signal

Wi-Fi interference serves as a tactic employed by criminals to hinder or obstruct wireless signals, effectively preventing communication between devices connected to a Wi-Fi network. The radio frequencies emitted by these jammers can disrupt the seamless operation of the Wi-Fi network, resulting in its unreliability or complete inability to function.

Radio frequency interference

The functioning of jammers involves the transmission of radio signals on the same frequency band utilized by Wi-Fi networks. This interference hampers the smooth transmission and reception of data packets, thereby rendering it impossible for legitimate users to gain access to the network. Consequently, individuals attempting to connect to the targeted network will encounter severe connectivity problems or may find it completely unattainable.

Wi-Fi networks can be subjected to specific frequency bands through the use of different types of jammers. For instance, certain jammers are designed to operate on the 2.4 GHz band, which is commonly utilized by older Wi-Fi standards like 802.11b/g/n. On the other hand, there are jammers that can specifically target the 5 GHz band used by newer standards such as 802.11ac/ax.

By concentrating on specific frequency bands, criminals possess the ability to selectively disrupt devices or networks with certain capabilities and vulnerabilities. This strategic approach empowers them to exploit security system weaknesses, ultimately gaining unauthorized access to homes or businesses.

The invasion of organized crews and high-end homes

The tactics employed by organized crime syndicates to gain unauthorized access to homes are growing more sophisticated, with the utilization of Wi-Fi jammers for upscale break-ins. These criminal networks specifically set their sights on high-end residences boasting advanced security systems, deeming them as optimal targets to engage in illicit pursuits.

Through the utilization of Wi-Fi jammers, thieves can effectively evade alarm systems and surveillance cameras that would typically obstruct or capture their actions. This technology enables them to operate covertly, providing them with a substantial advantage over homeowners who depend on these security measures to ensure their safety.

These well-organized operatives employ a methodical approach when selecting their targets, often investing considerable time in conducting thorough research and surveillance beforehand. Their primary objective is to identify residences with valuable assets, such as precious jewelry or valuable artwork, to ensure that the potential rewards outweigh the inherent risks. Once a target has been chosen, they meticulously plan every detail to ensure a successful break-in.

There are situations where these wrongdoers may go to the extent of impersonating service personnel or delivery personnel to gain entry into a property. By mingling with authentic professionals, they can seamlessly penetrate a heavily guarded residence without raising any red flags.

It is imperative for homeowners to acknowledge this growing menace and take appropriate actions to ensure their safety and protect their property. Going beyond traditional alert systems, investing in additional layers of security can act as a deterrent to these organized criminals. For instance, the installation of motion sensor lights around the house or the use of smart locks that require biometric authentication can provide an extra level of protection against these resourceful wrongdoers.

Homeowners must prioritize staying well-informed about the latest techniques employed by criminals and maintaining a vigilant mindset to ensure the safety of their homes. By staying ahead of the game and implementing comprehensive security measures, homeowners can greatly diminish the likelihood of falling prey to these organized wrongdoers.

Dad Uses Signal Jammer to Stop His Kids from Going Online

Inadvertently, a resident from the town of Messanges in southwestern France may be sentenced to six months in jail for unknowingly causing disruption to telephony and mobile internet services in his neighborhood by using a signal jammers.

Unexpectedly, his actions were not driven by ill will. His sole purpose was to hinder his teenage kids from going online on their mobile devices after their designated bedtime.

In a recent development, the French planning and radio frequency management agency (ANFR) highlighted an unusual grievance lodged by a local mobile phone operator. According to the complaint, the residents of Messanges faced a disruption in their cellular and mobile internet services every week, precisely from before midnight until 3 AM.

A peculiar complaint was lodged by a local mobile phone operator, as revealed by the French planning and radio frequency management agency (ANFR). The complaint highlighted the inconvenience faced by the residents of Messanges, who were unable to utilize their cellular and mobile internet services from midnight until 3 AM every day of the week.

After a thorough investigation, the ANFR has determined that radio frequencies in the area were being disrupted by a mobile phone jammer, a device that is prohibited in numerous European countries, including France.

At approximately 1:30 am, a skilled technician managed to pinpoint the exact location of the signal to a residence situated in the coastal town. Subsequently, the investigators, in the company of police personnel, proceeded to knock on the door of the individual. Without delay, the man openly acknowledged his use of a multi-band jammer.

The ANFR provided an explanation stating that the father of the family had installed a jammer in order to stop his teenagers from using their smartphones to access the internet instead of going to bed. The primary reason for this action was the children's addiction to social networks and various applications. After conducting research on online forums, the father concluded that a jamming wifi
would be the most suitable method to put an end to his kids' excessive screen time.

Version 2: In addition to instructing the owner to disable the jammer and discontinue its usage, the ANFR agent highlighted the significance of complying with the regulatory framework, as mentioned by the agency.

According to experts, teenagers should strive to keep their screen time under two hours per day. The excessive use of phones can have adverse impacts on their physical and mental health. Additionally, excessive screen time has been linked to the development and progression of myopia, as well as conditions such as dry eye syndrome, digital eyestrain, and discomfort resulting from poor head and neck postures cell phone blocker.

The curiosity surrounding the activities of teenagers on their smartphones led Harvard researchers Emily Weinstein and Carrie James to embark on a study. Their findings revealed a complexity that often eludes adults. By surveying a vast sample of over 3,500 teenagers across the United States, they gained insights into the motivations behind sexting and the strategies employed by teens to navigate online friendship dilemmas.Their research has made a profound impact on me. It is astonishing to realize that as adults, we frequently offer unhelpful advice and simply dismiss teen phone use as a mere addiction. As a result, parents are failing to seize genuine opportunities to aid teenagers, as stated by their study wifi blocker.

Again and again from teens that they don't want to feel dysregulated when it comes to their technology use, and that they actually have pretty impressive, even amazing awareness of what tech habits they have that are serving them and the tech habits that they wish they could change. We had so many quotes from teens about just this feeling of, I don't know why, but this app, TikTok is running my life, or I keep falling asleep on social media and I wish I didn't. And what we found that's actually so powerful about that recognition is that adults often get really stuck in this position of being like a referee when it comes to teens technology use, where we're just blowing the whistle when kids do something wrong or calling teens out when they misstep. We get stuck in this position.

Want to Keep Your Teens (or Employees) from Texting Behind the Wheel?

I have reason to believe that there is a rising trend of individuals tampering with GPS applications while driving, leading to potential distracted driving dangers that are contingent upon the particular app and the location of the device.

I like the texting-blocking angle myself, but I’m leery of the general data-blocking one. What about apps that use differential GPS? (Satellite plus base station data-path corrections, for greater precision.) What about streaming audio apps, like Audible or Spotify? (I use both on extended drives, and I’d hate to tell either a teen or employee she couldn’t, just to block texting). What if the driver wants to hand her smartphone off to someone else in the car to use for some data-related function, say looking up a restaurant or fiddling with the GPS or just checking email or text messages on behalf of the driver? (My wife did this for me for over a year whenever I drove, until she got her own smartphone.)
