We are presently tenants of a house. The neighborhood can get quite noisy late at night, even past midnight, as our neighbors blast their music.

Seeking assistance from law enforcement proves to be fruitless. Despite my repeated calls, their commitment to dispatch someone to address the issue remains unfulfilled. Consequently, I commenced researching signal blockers that specifically target wifi signals, excluding cellular ones. Fortunately, I discovered a device that appears to be an ideal choice.

Admittedly, I had my doubts about their payment procedures initially. Nonetheless, I quickly realized that their product was precisely what I had been seeking.

I completed the payment and waited patiently. The standard shipping timeframe is set at 7 to 15 days.

Once day 15 had elapsed, we were provided with the tracking details. Subsequently, it underwent port clearance and was then entrusted to DHL for delivery. Remarkably, within a span of 2 days, the package was delivered to its final destination.

Having extracted it from the packaging, I promptly affixed the antennas and established the connection with the charger. To my satisfaction, the battery was already fully charged.

Several days passed before we were confronted with the unwelcome music that kept us awake. Determined to address the issue, I retrieved the device from the nightstand and switched it on. It is worth mentioning that these neighbors reside a few houses away from us. To my astonishment, the music suddenly fell silent after a few seconds. Subsequently, I overheard individuals discussing the problem. In order to assess the situation, I allowed it to play for a good 20 minutes. Finally, I turned it off and went to bed.

When I first charged the jammer device, it unexpectedly emitted a loud bang and smoke, rendering it inoperable. Upon reaching out to the company, I was assigned an RMA return number and instructed to send the device to China for repair or replacement. The return shipping incurred an additional $25 charge, in addition to the initial cost of over $350. It was a lengthy process to finally obtain the repaired radio signal jammer.

Without a doubt, the cell phone signal jammer is a legitimate enterprise, as you asked. It seems that some reviews are dubious. I can confirm this with evidence in my possession.

Charges have been brought against them for participating in computer criminal activity by supposedly causing disruptions to the network as requested by their companions.

Authorities announced on Monday that two 14-year-old boys are facing charges for intentionally interfering with their school's Wi-Fi network to skip exams.

As per NJ.com, New Jersey high school freshmen have been accused of engaging in computer criminal activity and conspiring to commit such acts. School administrators contacted the police last Thursday after the Wi-Fi network experienced multiple crashes throughout the week.

As per the information provided by Capt. Dennis Miller to NorthJersey.com, the administration of Secaucus High School reached out to the Secaucus Police Department to report that two students were engaged in a "scheme to disrupt the school's WiFi service whenever instructed."

Due to their status as minors, the names of these individuals have not been made public. They have been handed over to their parents and are scheduled to make an appearance in the juvenile family court located in Jersey City, with the exact date yet to be determined.

In a recent statement, Schools Superintendent Jennifer Montesano confirmed that the Wi-Fi has been restored and is operating smoothly. While she refrained from sharing specific details, she did acknowledge that an investigation uncovered two students who may have been responsible for the system disruption.

How did they do it?

A number of students shared with NJ.com their belief that the boys were employing a Wi-Fi interrupter program or app to overload the school's routers with traffic in a denial of service (DoS) attack. This attack led to the network crashing when students tried to log on for classwork or online exams.

A junior student from Secaucus High School revealed to the news outlet that she found out about the Wi-Fi problem when a friend informed her that one of the suspects had been requested to interfere with the signal during an exam.

It was done for both the exam-adverse and for fun, she said:

The motive behind his actions was to escape examinations and similar tasks. Moreover, one of the boys carried out this act on behalf of his friend, ensuring she would not have to undergo a test during the class. Undeniably, it constituted a significant prank.

Jamming phones, Wi-Fi and GPS is illegal

Some students were disgruntled – why should the whole class be disrupted because a few kids didn’t feel like squeezing out some brain juice that day? Others were impressed by the boys’ alleged technical acumen and sported more of a “Meh! Nobody got hurt” reaction, like this 10th grader:

It was unexpected to see someone as young as us, or nearly our age, achieve something like this.

People's education is being tampered with, although no harm is being inflicted upon anyone.

With respect to the first issue, it is recommended that those students do not place too much emphasis on their classmates' alleged technological proficiency. Despite the fact that gsm jammer are illegal to market, sell, or use in the US - except for authorized, official use by the federal government - they are readily accessible online for a few hundred dollars.

signal jammer are not just an inconvenience; they represent a dangerous hazard to public safety as they have the potential to block crucial emergency communications. cell phone jammer are unable to make a distinction between regular phone calls and emergency calls to family members or 9-1-1 responders. In a similar manner, GPS and wifi jammer disrupt both routine and essential communication services.

In the past, there was an incident involving a man who faced felony charges for intentionally interfering with the phone signals of his fellow commuters. His frustration with their conversations led him to take such action.

While it may be true that no harm was caused by the school Wi-Fi jamming, it is important for children to understand that this is not a harmless prank. The potential repercussions are significant and should not be taken lightly.

WBTV reports that CMPD has discovered instances where thieves have skillfully circumvented surveillance cameras during home break-ins, thanks to their use of technology.

Cell-jamming is the term used to describe the interference caused by an individual using a device to disrupt radio or wireless signals.

The Federal Communications Commission has made it clear that intentionally using a phone jammer, GPS blockers, or any other signal jamming device to interfere with authorized radio communications is a violation of federal law. It is essential to recognize that this prohibition applies without exception, regardless of whether it is within a business, classroom, residence, or vehicle.

Cell-jamming is possible from a device roughly 30 feet from the target, or household security cameras.

In a south Charlotte community, a video has emerged showing a suspect surreptitiously navigating through a yard during the nighttime. It is worth mentioning, though, that not all incidents have been captured on camera.

John Shocknesse, VP of Customer Operations for CPI Security, highlighted the need to address potential interference with wireless devices and the importance of implementing strategies to prevent communication disruptions.

In a split second, someone might show up on camera, but the presence of cell-jamming enables their swift disappearance through the mere act of flipping a switch or pushing a button.

In south Charlotte, CMPD has identified this as a recurring problem during residential burglaries.

Shocknesse acknowledged the lack of any such activity, highlighting the significance of being vigilant and equipped with the latest technology.

WBTV sought his opinion on which devices are more prone to cell-jamming.

Shocknesse pointed out that the issue arises primarily with older wireless devices that lack encryption.

He stated that newer security systems and surveillance systems are built with improved technology, such as encryption, to provide heightened security.

Shocknesse pointed out the critical role of cameras and onboard recording in ensuring that events are documented and can be provided to law enforcement if needed.

Additionally, he recommended that the most efficient way to prevent cell-jamming is to utilize up-to-date technology with encryption and to use a wired device instead of relying on Wi-Fi.

Effective measures to prevent break-ins at home include maintaining proper lighting, utilizing alarm systems, and ensuring that bushes are trimmed to a maximum height of three feet.

The Los Angeles authorities have revealed that a group of thieves has been outfoxing smart devices throughout the area.

A statement from the Los Angeles Police Department on March 4 highlighted concerns about a group in Wilshire using Wi-Fi jamming technology to deactivate surveillance cameras and alarm systems that rely on Wi-Fi.

The recent spate of tech-savvy robberies in California forms part of a wider trend of technologically advanced criminal activities occurring nationwide. In the past year, law enforcement authorities in Minnesota and Connecticut also issued cautionary advisories to residents regarding organized groups of thieves skilled in Wi-Fi jamming. These examples are just a fraction of the numerous instances reported.

KARE11 has reported that even though the Federal Communications Commission has prohibited Wi-Fi signal jammers jamming devices, criminals can still purchase them inexpensively. These devices do not necessarily disable other devices but rather overload the network they are connected to.

The intention behind these devices, as explained by cybersecurity expert Mark Lanterman, is to obstruct radio transmitters and create traffic congestion that hinders genuine communication.

He recommended that if you opt for a Wi-Fi camera for your front door, you should perhaps contemplate using a hardline camera inside your home. Wired cameras connected through Ethernet cables do not rely on Wi-Fi networks and are not vulnerable to interference caused by a wifi jammer.

It is strongly recommended by the Los Angeles police to have burglary alarm systems hard wired.

Tom’s Hardware states that while smart technology may be a contributing factor to the issue, it can also be part of the solution. It is recommended by officials to employ timers or smart home devices to simulate occupancy when you are not present. Furthermore, certain smart home technology is capable of notifying users in the event of signal or connection disruptions.

In addition, Tom's Hardware recommends connecting surveillance devices directly to your device for storing camera footage, rather than solely relying on a cloud storage system. This way, even if there is a Wi-Fi disruption, the footage will still be saved and accessible.

The LAPD promotes vigilance among residents through the practice of securing doors, enlisting neighbors to watch over their homes during absences, and reporting any suspicious behavior, including the presence of vehicles with temporary or dealer plates.

Wilshire Park is located in Central Los Angeles.

The significance of mobile phones as a means of communication in people's everyday lives cannot be overstated. Nevertheless, there are certain circumstances where mobile phone signal jammers hold particular importance. This article provides a comprehensive analysis of mobile phone signal jammers, exploring their technical principles and application scenarios. By delving into these aspects, readers can gain a profound understanding of the technology and the valuable applications it offers.

How mobile phone signal jammer works

The key working mechanism of the mobile phone signal jammer is to emit signals at the identical frequency as mobile phone communication, albeit with increased power to disrupt the original signal. This interference signal will mask or overpower the signal typically received by the mobile phone, rendering the mobile phone incapable of establishing normal communication with the base station, thereby effectively blocking the signal.

The interference signals produced by jammers are tailored to disrupt particular frequency bands, such as GSM, CDMA, 3G, 4G, and even the most recent 5G network bands.

The coverage area of cell phone jammer is determined by the power level, where higher power equates to a larger coverage range.

Types of cell phone signal jammers

With its small and portable design, this jammer is well-suited for personal or small-scale applications, such as conference rooms and small offices.

Specifically crafted for environments like schools, examination rooms, prisons, and more, this high-power jammer is ideal for a variety of needs.

Specialized jammers are created to cater to the distinct needs of specific locations, like military compounds, government offices, and other sensitive sites.

The principle and application of GPS signal jammer

GPS signal inhibitors generate electromagnetic waves at particular frequencies that disturb signals from GPS satellites, hindering GPS receivers from properly understanding satellite signals. This method is reminiscent of standard electronic jamming devices, but is tailored to the GPS frequency band.

GPS signal jammers usually work in the 1575.42 MHz frequency band, which is the main frequency of GPS satellite signals. Their operating range can vary depending on design and purpose, from a few meters to hundreds of meters.

The primary use of portable gps jammer is to protect personal privacy, whereas fixed jammers are primarily employed in professional fields like the military and government, providing a higher power output and wider range.

By employing GPS signal jammers, the military can interfere with the navigation systems of the enemy, effectively preventing them from accurately determining their positioning and navigating.

Some people or organizations could make use of GPS signal jammers to stop location tracking and safeguard personal privacy.

The AIIMS entrance exam controversy may have come as a shock to many, but the city university has implemented precautionary measures to avoid such incidents. While certain universities have chosen to install jammers at entrances, others have opted for metal detectors or security guards. However, only a few universities have taken the initiative to implement all of these measures. Jammers effectively detect mobile signals, thereby preventing students from resorting to unfair practices.

Two years ago, Ms. Kang, the director of Punjab College of Technical Education (PCTE), made the decision to install jammers in the exam hall. This action was taken during a period when approximately 900 students were in the midst of their exams. Ms. Kang expressed her belief that a disruptor could effectively address the problems faced by all individuals by disabling their cell range cell phone jammer.

At Guru Nanak Institute of Management and Technology (GNIMT), director HS Singha revealed that the deployment of two jammers on the campus three years ago has significantly decreased cheating occurrences. Moreover, strict physical checks are carried out to prevent students from bringing phones into the premises.

MS Saini, who serves as the principal of Guru Nanak Dev Engineering College (GNDEC), highlighted the concerning trend of students resorting to unfair methods to improve their academic performance. He noted the challenges associated with physical verification, given the students' increased capabilities, leading to the installation of 11 jammers on campus. Moreover, the college has implemented the use of three metal detectors and bolstered security measures at the entrance gates wifi jammer.

Ludhiana College of Engineering and Technology's principal, Pawan Kumar Gupta, informed that they had set up five jammers and two metal detectors on the campus roughly three years ago. He stressed that if all academic institutions followed suit in deploying these tools, the risk of cheating through technology would be significantly reduced.

Can mobile jammers in colleges stop cyber crime?

The idea of banning mobile phones on university campuses has generated concern among students in the city. The Maharashtra government's higher and technical education department is considering this measure as a means to tackle cybercrime within universities signal jammer.

Nonetheless, students were disheartened by the perceived encroachment on their liberties. Lala Atole, a student at ILS Law School, asserts that the proposed ban lacks any logical basis.

"School authorities can impose stricter rules on the use of mobile phones in classrooms, but installing jammers will directly impact students' freedom," he said. Some students believe that installing jammers will not affect most students as they are addicted to gaming during classes. "If cell phones are banned and we can't even answer important calls, students might think of skipping lectures. How does that help students?"

Garware College student Vedang Bhagwat posed a query. Despite students expressing dissatisfaction with the decision, there is a division among university authorities regarding the proposal. The authorities are considering the installation of jammers in classrooms, but are hesitant to implement them throughout the campus gsm jammer.

Hrishikesh Suman, principal, Symbiosis College of Arts and Commerce, opined, "Jammers will definitely help prevent distractions during classes. However, outside the classroom, this may affect the internal academic communication with the teacher." Only by getting the power to control jammers, The authorities will welcome this move. "Signal jamming affects our security systems and hampers emergency communications. Also, students are not used to restrictions and this may do more harm than good," said Dilip Sheth, Principal, SP College. Teachers believe it would be more helpful for students to voluntarily refrain. “Students should voluntarily refrain from using mobile phones without our close attention,” added MMCC principal MD Lawrence. Some even favor the use of cell phones on campus.

Girija Shankar, vice-chancellor of Neswadia Business School, emphasized that disruptors are not the answer, especially considering the large population of out-of-town students in Pune whose guardians regularly need to reach out to them.

Feb. 16 started like any typical Friday night. My husband and I decided to stay home, grill chicken and make a salad for dinner. At about 6:45 p.m., we heard some loud rumbling overhead.

We walked onto the back patio, and two police helicopters were overhead – shining lights all over our property, and a recording echoed, "Police. You are under arrest. Stay right there and I won't shoot you."

As I looked across the fence, a swarm of armed members of the Phoenix SWAT Team with a few dogs were circling our property. One of the guys said, “Yeah, there’s a signal jammer right here.” He picked it up. I leaned over the patio and asked, “What’s going on?”

The police told me to go inside

A SWAT member said, “Ma’am, A South American gang is targeting homes to steal from. The cell phone jammer says you might have been next. Do we have permission to enter your property?” I said, “Yes!” and then he asked something like, “If we find anyone, will you pursue charges so we can arrest them?” I replied, “Of course!”

I opened the driveway gates to our property and the guest house while Barry tossed the police keys to open the security gates. It turns out that when the gang saw we were home, they likely diverted their attention to the house next door. A house four doors down from us wasn't so lucky.

The homeowner left at 5 p.m. to have dinner and got a notification his security cameras were offline at 5:05 pm. He thought the internet went down. The gang broke in and took $25,000 in cash and valuables worth $100,000. They were in and out in less than 10 minutes.

How are they getting away with this?

The gang places cellular and wifi jammer around the homes they’re targeting. This way, security cameras and phones are useless. A Phoenix police officer told me the gang probably noticed nothing was down in our house.

Our home’s security cameras and internet are hard-wired. Even when the thieves tried to jam the Wi-Fi signals, the security camera’s red lights showed they were recording everything. We also still have a landline.

But how frightening is that? Your phone doesn't work. Your cameras aren't recording anything. On the upside, the gang doesn't carry guns. If they get caught, they'll spend about six months in jail before being extradited to Chile.

If you’d like to watch the action captured by my security cameras, I showed them during a Kim Komando Today video stream. I am so thankful for our police force.

Nothing is random

The gang thoroughly scopes out homes beforehand. They drive the neighborhood and look up homes on real estate sites to get an idea of where the primary bedroom is located. They look for dogs, too.

It’s not only a problem in Phoenix. This is happening all over the country. A friend was robbed by a similar gang in a guard-gated community in California. Kudos to Phoenix Police – they arrested three members of the gang who were in my neighborhood that night.

I read a few of the news articles and it sounds like the thieves are jamming WiFi and the sensors. This prevents the system from even triggering. The thieves are walking around the homes without the glass break, door, and motion sensors going off it seems.

Not commonplace, but getting some exposure in the news recently - gangs of organized thieves in metro Detroit area are targeting upper scale homes for burglaries. They are purportedly using wifi jammer to circumvent alarms (like Ring).

What can millions of Ring (and customers from other wifi-dependent alarm companies) do about this? IS there a viable counter to these signal jammer? Maybe it's time to explore legacy, analog wired alarm solutions as backup instead of the reverse?

They're using a wifi jammer, according to this article. No obvious way to prevent this, so hardwired systems would be the only resistant option.

Most Wi-Fi jammers use disassociation flooding to kick the devices off the network. This attack is prevented with WPA3 which can use protected management frames. Unfortunately Ring still hasn’t got around to adding WPA3 support to its devices. It was requested via their feature request process a long time ago, so I’m not overly hopeful they’ll add it.

There are trade offs and risks with each security system. There’s also different types of burglars from opportune amateurs to seasoned pros.

If you’re concerned about this threat, there’s a raft of solutions out there with high definition footage without any reliance on Wi-Fi or internet.

Whatever they're using for jamming must go beyond the WiFi frequencies to affect z-wave and whatever frequency Honeywell et al uses for their RF communications.

This makes sense because most alarm systems these days (even ADT/Brinx/etc) rely mostly on wireless sensors.

This is a huge vulnerability because it's pretty rare to find a security system that's been installed to use all hardwired sensors. To go hardwired you probably had to have it built-in as the house was built or did it while doing some major remodeling.

Cellular jammers are readily available. DSL, cable, or fiber are not jammable, but all devices need to be hardwired.

Zwave can be jammed just as easily as wifi. Cellular is great but if the door/window sensors are blocked and unable to report to the base station, the alarm won't think anything is wrong.

What I found when doing some simple research over the last couple of days is that different manufacturers use different frequencies for their devices so it might be a guessing game for the burglar, although my guess is that the professional burglars carry jammers for most of the common frequencies used by the big name brands like Ring, Simplisafe, Nest(ADT), etc.

To me it makes sense to have devices from different brands. Ring doorbell, ADT alarm, Wyze cameras, etc...

What's scary is that there are a bunch of videos on youtube demonstrating how easy it is to bypass these alarms AND with instructions telling you exactly how to do it and how to get the jammers.

Is this pervasive? If you watch the news, it’s pretty evident thieves aren’t concerned with cameras. They mask up and hood up and go. Be on alert, they have no fear.

Burglars can use wide-band jammers to jam all frequency bands : GSM, LTE, Wifi and Z-Wave. Some alarm systems are robust to such attacks (like Ajax Alarm System -- https://ajax.systems/blog/what-is-jamming/).

In short, the alarm hub must be hardwired with Ethernet to your router; And hub, router and modem on a battery backup. Then, only communications between sensors and hub can be jammed.

Then, alarm hub communicates frequently with sensors. If communication fails, it signals a jamming attack, notifying the user via hardwired Internet. With a working speaker on the hub, it can sound a siren and send a voice alert to the intruders.

SimpliSafe system is another system that offers some jamming protection, but lacks the Ethernet hardwired connection, so it must rely on a GSM/LTE link, which is still better than Wifi alone.

The Department of Telecommunications (DoT) has released a warning regarding the unauthorized use of cellular signal jammers, GPS blockers, or other signal jamming devices by individuals, stating that it is prohibited unless officially authorized by the government.

The Department of Telecommunications (DoT) recently released a memorandum on July 1, addressing the public's interest. In this memorandum, it was explicitly stated that the government-approved jammers can only be procured and utilized by states, union territories, defense forces, and central police organizations.

The advisory indicated that private sector entities and individuals in the private sector are prohibited from purchasing or utilizing jammers in India.

Examination conducting bodies under the union/state government or union territories can utilize jammers procured from authorized vendors and approved models, following the necessary approval from the competent authority.

Additionally, the Department of Telecommunications has declared that promoting, selling, delivering, importing, or otherwise promoting jammers in India is illegal, unless authorized by government regulations.

The Department of Transportation (DoT) has declared the utilization of mobile signal repeaters and boosters by individuals as illegal, not limited to jammers. According to a memo, the unauthorized use of repeaters can have a negative impact on public telecommunication services by compromising their quality and coverage, leading to interference and disruption.

In January, the Department of Telecommunications (DoT) issued a strong caution to e-commerce entities such as Amazon, Flipkart, Snapdeal, Alibaba, Aliexpress, Ebay, and others regarding their involvement in enabling the trade of wireless jammer.

The Federal Communications Commission has imposed a $126,000 fine on an oilfield company for blocking cellphone calls. The company must contest this fine before the May deadline.

The FCC's notice of apparent liability against Taylor Oilfield Manufacturing Inc. of Broussard, issued on April 9, cited the company for allegedly employing four cellular phone jammers to hinder employees' cellphone usage.

Company executives disclosed to the FCC that the cell jammers, which obstruct cellphone signals, were utilized to discourage employees from using their cellphones in the workplace.

From April 9 onwards, Taylor had a 30-day window to either pay the penalty or submit a written response to the FCC outlining reasons for the cancellation or reduction of the fine.

Taylor officials refrained from responding to phone calls seeking comment.

The commencement of the case took place after the FCC was tipped off and dispatched an agent to the company's premises in Broussard in May 2012. According to the FCC notice, company representatives acknowledged the use of four cell jammer and the possession of a fifth cell jammer, which was not currently in use.

The United States has a strict prohibition on the use of cell jammers, and the FCC has explicitly forbidden companies from importing these devices from foreign nations. According to the FCC, the Broussard company confessed to purchasing its cell jammers from overseas sources.

The FCC's notice to the company underlines the concrete risk to public safety resulting from the unlawful operation of signal blockers. This risk includes the possibility of blocking authorized communications, including emergency calls to 911 and law enforcement communications. Additionally, the use of cell jammers can negatively impact global positioning system signals.

As per FCC documents, Taylor's officials disclosed that the company sought to block employee cellphone use after a near accident that was said to be partially caused by an employee using a cellphone.
