The uproar surrounding the AIIMS entrance exam may have surprised many, but the city university has proactively taken measures to prevent such incidents. While some universities have installed jammers at entrances, others have opted for metal detectors or security guards. However, only a few have implemented all of these precautions. Jammers play a crucial role in detecting mobile signals and discouraging students from resorting to unfair means cell phone jammer.

The installation of jammers at the exam hall of Punjab College of Technical Education (PCTE) was initiated by Ms. Kang, the college's director, two years ago. This measure was taken when nearly 900 students were undergoing their examinations. Ms. Kang highlighted the potential of a disruptor to resolve the issues faced by everyone, as it would render their cell range inoperable.

The director of Guru Nanak Institute of Management and Technology (GNIMT), HS Singha, highlighted the successful implementation of two jammers on the campus three years ago to combat cheating. Furthermore, stringent physical verification measures are in place to ensure students do not have phones in their possession wifi jammer.

The principal of Guru Nanak Dev Engineering College (GNDEC), MS Saini, raised an issue regarding students' inclination towards using unfair means to secure better grades. He pointed out the difficulty in conducting physical verification due to the advanced skills of students, which prompted the installation of 11 jammers on campus. Additionally, the college has introduced three metal detectors and reinforced security protocols at the entrance gates.

The principal of Ludhiana College of Engineering and Technology, Pawan Kumar Gupta, revealed that the institution had introduced five jammers and two metal detectors on campus around three years back. He highlighted that the utilization of these devices across all educational establishments could greatly diminish the potential for academic dishonesty via technological means signal jammer.

Can mobile jammers in colleges stop cyber crime?

The possibility of prohibiting mobile phones on campus has caused unease among students in universities throughout the city. In an effort to combat cybercrime, the Maharashtra government's higher and technical education department has put forward this proposal.

Nonetheless, students felt let down by the perceived infringement on their rights. Lala Atole, a student at ILS Law School, contends that the proposed ban is devoid of logic.

"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?"

A student named Vedang Bhagwat from Garware College raised a question. Although students are unhappy with the decision, there is a disagreement among university authorities regarding the proposal. While they are contemplating installing jammers in classrooms, they are reluctant to extend this measure to the entire 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.

The vice-chancellor of Neswadia Business School, Girija Shankar, pointed out that disruptors are not an effective solution given the significant presence of out-of-town students in Pune whose guardians frequently require communication with them.

Authorities with the Los Angeles Police Department are warning residents in Los Angeles’ Wilshire-area neighborhoods of a series of burglaries involving wifi jamming technology that can disarm surveillance cameras and alarms using a wireless signal.

According to police, the burglaries typically involve three to four suspects who enter homes through a second story balcony.

Once inside, the thieves target primary bedrooms in search of high-end jewelry, purses, U.S. currency and other valuables.

“On many occasions, these suspects will have a getaway vehicle and driver to act as a look out,” authorities said in a community alert.

To deter these types of burglaries, authorities provided the following tips:

• Ensure your electrical circuit boxes are secured with a padlock to make it harder for thieves to tamper with alarm systems


• Never tell Uber, Lyft or taxi drivers or post on social media that you will be on vacation or away from home


• Stay alert for suspicious vehicles with temporary or dealer plates, as well as rental vehicles


• Share your cellphone number with trusted neighbors and ask them to clear your mail and keep an eye on your residence if you plan to be away


• Place cameras around the home and ensure that the alarm DVR is secure and cannot be tampered with


• Consider moving to an alarm system that is hard wired rather than running on a wireless signal


• Provide extra security such as a pole to sliding glass doors to eliminate easy opening


• Place tracking devices, such as Apple AirTags, on valuable items like jewelry boxes, purses or vehicles


• See what shrubbery or trees can be trimmed or cut to keep your residence highly visible


• Install proper lighting and security signage and always leave light on in your home, especially while away

Anyone with information on any of these crimes is encouraged to contact LAPD’s Wilshire Burglary Detectives at [email protected]. Those wishing to remain anonymous can contact L.A. Regional Crime Stoppers at 800-222-8477 or online at L.A. Crime Stoppers.

A recent caution has been issued for those who rely on wireless security cameras like "Ring" for safeguarding their residence.

In Detroit, a woman reported that her Ring camera failed to record the theft of her car from the front of her residence. An expert in the area suggests that this occurrence signifies the growing technological expertise of criminals.

The woman stated that her car was stolen from her driveway earlier this month. Upon reviewing the footage from her Ring camera, she noticed that there were missing hours.

The statement made by Chris Burns, the proprietor of Techie Gurus, highlights that security cameras relying on WiFi for recording purposes are primarily focused on convenience rather than security. This is attributed to the vulnerability of WiFi signals to interference, potentially leading to the camera's inability to effectively surveil the surroundings of your home, a concern that criminals are exploiting.

According to Burns, using wireless for security measures is a flawed approach. He pointed out that wireless signals can be easily interfered with or obstructed.

These individuals can employ this as a wifi jamming device, or a deauther, that could potentially be as compact as an Apple Watch.

By standing within close range, a deauther can overpower a WiFi system, compelling the WiFi camera to cease its recording operations. This accessory is available at a relatively affordable price, typically ranging from $10 to $50. On the other hand, a jammer comes at a significantly higher cost, with prices ranging from $150 to $1,000.

Due to their illegal nature, singal jammer are not easily accessible. Nevertheless, a strong camera jammer can effectively stop an entire street from being captured on WiFi security cameras by a mere push of a button.

In a statement, a representative from Ring highlighted the potential impact of WiFi signal interference on Ring device performance, similar to other wifi-enabled devices. Customers encountering connectivity issues are urged to seek help from Ring Customer Support.

How can customers protect themselves?

According to Burns, true security can only be achieved by utilizing hard-wired connections like ethernet.

The spokesperson representing Ring stated that they are mindful of the situation, highlighting its infrequency.

According to Burns, as technology becomes more affordable, the demand for jammers is expected to rise. Hence, it is imperative to ensure that people are adequately educated on this subject.

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.

How to stop wifi jammer attacks on home security systems

Recently, a news story originating from Queens, New York captivated audiences as it depicted a burglar smoothly gliding across the floor, clutching an unknown device. Speculation arose, suggesting that the device in question was a wifi jammer, cleverly utilized by the intruder to disrupt the home's wifi network and render the alarm system useless, thereby ensuring his undetected presence.

Is this even possible? Yes, yes it is.

So what is a wifi jammer?

Generally, these jamming devices create a signal that causes interference on the spectrums utilized by 3G, 4G, 5G, cordless, and wifi networks. Essentially, they impact all of these networks.

The excessive noise effectively hinders devices from utilizing the frequencies required for normal operation. Consequently, this interference also affects emergency networks utilized by first responders, leading to the prohibition of such devices. However, these illegal devices are manufactured and sold on the black market, and individuals have the capability to construct their own. It is advised against searching for instructions online, as it may result in being placed under surveillance.

The purpose of a jammer is to produce interference that interferes with the frequencies used by our devices, rendering them ineffective. As these frequencies propagate from the signal blocker device, they have the capability to impede a wide range of devices, even those not specifically targeted by the user.

Now that you are aware of this, do you think it could cause disruptions to your phones, alarm sensors, alarm base station, smart locks, and wifi cameras? Yes, it is a valid concern.

It is understandable if you have the following question: "Andy, my alarm system has a cellular backup in case the wifi connection fails. Will it continue to operate?" Unfortunately, that is not the case. The sensors will lose their ability to communicate with the base station due to the interference caused by these jammers. It is important to remember that these jammers not only disrupt wifi signals but also block mobile spectrums, thereby preventing your base station from making calls over wifi or a cellular network.

How To Stop Wifi Jammer and Deauth Attacks

Now that we have insight into the types of attacks and their effects, how can we effectively counteract them? Have you heeded my advice against prominently displaying the alarm company branded sign in your yard?

That is the rationale behind keeping your home security details private to prevent criminals from taking advantage of any vulnerabilities. Identifying businesses that operate on the 2.4 GHz band is a straightforward task.

When investing in new smart home technology, prioritize devices that support dual-band connectivity or operate on the 5 gigahertz spectrum. While WPA3 security is said to offer protection against such attacks, the extent of its effectiveness remains unclear to me as a beginner. Unfortunately, wireless alarm systems are currently vulnerable to jammer attacks.

You have the option to choose a conventional method by setting up a fully wired home alarm system that functions using a landline connection. As long as there are no wireless features, you should be fine.

Security Cameras With SD Card Storage

Cameras offered by companies like Ring are equipped with local storage functionality. This means that in situations where wifi is down or cloud storage is not available, these cameras utilize their internal storage to store recorded clips. Although you may not receive notifications, you can conveniently review the footage by accessing the SD card directly within the camera.

In order to enhance the security of your home, it is advisable to supplement your wifi camera system with an affordable local storage camera. This way, even if you encounter a jammer or deauth attack, you will have one camera that continues to capture footage. However, it is important to consider that if the attackers become aware of the camera's presence, they may attempt to destroy it and steal it.

An advisory has been issued by the Department of Telecommunications (DoT) cautioning against the utilization of cellular signal jammers, GPS blockers, or other signal jamming devices by members of the public, as it is considered unlawful unless expressly approved by the government.

On July 1, the DoT issued a memorandum of public importance, clarifying that the government-approved jammers are exclusively available for procurement and usage by states, union territories, defense forces, and central police organizations.

According to the advisory, private sector organizations and individuals in the private sector are not allowed to acquire or operate jammers in India.

Authorized vendors provide jammers that can be utilized by examination conducting bodies under the union/state government or union territories, subject to approval from the competent authority.

Moreover, the DoT has affirmed that the advertising, selling, distribution, importation, or any other form of marketing of jammers in India is prohibited, unless authorized by official government directives.

In addition to jammers, the use of mobile signal repeaters and boosters by individuals has been deemed unlawful by the Department of Transportation (DoT). A memo issued by the DoT highlights that the unauthorized use of repeaters can have detrimental effects on public telecommunication services, as it can interfere with and disrupt the quality and coverage of such services.

The DoT had previously issued a firm warning to various e-commerce companies, including Amazon, Flipkart, Snapdeal, Alibaba, Aliexpress, Ebay, and others, about their role in facilitating the sale of wireless jammer back in January.

The oilfield company is required to challenge a $126,000 fine imposed by the Federal Communications Commission before the May deadline. This fine was levied against the company for interfering with cellphone calls.

On April 9, the FCC issued a notice of apparent liability against Taylor Oilfield Manufacturing Inc. of Broussard for allegedly deploying four cellular phone jammers to restrict cellphone usage among employees.

The company representatives informed the FCC that the cell jammers, which interfere with cellphone signals, were implemented to deter employees from using their cellphones during work hours.

Taylor was granted a 30-day period starting from April 9 to either settle the penalty or provide a written response to the FCC explaining why the fine should be waived or decreased.

Taylor officials failed to reply to phone calls requesting a statement.

The case commenced subsequent to the FCC receiving a tip and dispatching an agent to the company's premises in Broussard in May 2012. As per the FCC notice, company representatives acknowledged the utilization of four cell jammer and the possession of a fifth cell jammer, which was not operational at that time.

The United States strictly prohibits the use of cell jammers, and the Federal Communications Commission (FCC) has imposed a ban on importing these devices from foreign countries. According to the FCC, the Broussard company admitted to purchasing its cell jammers from overseas.

The company was notified by the FCC that the illegal use of signal blockers presented a significant risk to public safety as it could potentially disrupt authorized communications, including emergency calls to 911 and law enforcement communications. Additionally, the use of cell jammers can have a negative impact on global positioning system signals.

Taylor's officials informed the FCC that they made an attempt to restrict employee cellphone usage following a close call that the company attributed in part to an employee using a cellphone, as per FCC records.

Prisons no longer possess any cellphone jammer as Corrections has quietly removed them all.

The technology that was introduced in 2008-09 to stop inmates from using smuggled mobile phones has led to expenditures exceeding $17 million.

Following their discovery of causing interference with the newly implemented safety systems for prison guards, the use of jammers has been discontinued since June.

The announcement of cellphone blocking in New Zealand prisons was accompanied by Corrections Minister Phil Goff's assertion that this measure represents a crucial progression in deterring prisoners from perpetrating further crimes while confined.

Recent information obtained under the Official Information Act discloses the number of cellphones confiscated from the 18 prisons under the management of Corrections over the past three years.

Corrections staff found 626 cellphones and over 750 cellphone-related items, which included batteries, chargers, and SIM cards, between January 2020 and November of the current year.

In response to the question of why inmates were smuggling cellphones despite the presence of cellphone jammers in the prison, Neil Beales, the Corrections chief custodial officer, stated that the jammers were removed in June.

The discovery was made that the jammers were causing disruptions to newly installed safety systems, particularly impacting the effectiveness of alarms used to ensure the safety of corrections officers.

The evolution of cellular technology has rendered jammers progressively obsolete.

Beales pointed out that the tool mentioned was just one of several methods employed to deter the use of cellphones in prisons. He emphasized that there are still several other more effective tools in place.

The array of features offered by Cellsense devices sets them apart in the field of cellphone detection. These devices are capable of detecting a diverse range of metals commonly found in cellphones, while also incorporating screening and x-ray functionalities. Furthermore, they employ the assistance of detection dogs to further enhance their metal detection capabilities.

Beale pointed out that some prisoners are willing to take extreme and elaborate measures to bring contraband into prisons, and we are always striving to be one step ahead of the new methods used for smuggling contraband into our correctional facilities.

In order to enhance their existing systems, Corrections has been evaluating new and emerging technology, as stated by the spokesperson. They have already started implementing full body imaging technology at multiple locations to identify contraband that may be hidden on or inside a person's body.

Corrections authorities in 2018 recognized that cellphone jamming technology had caused a communications blind spot near Rimutaka Prison, preventing the tracking of residents in a child sex offender unit located outside the prison perimeter.

Cellphones have the potential to enable inmates to exert pressure on individuals outside the prison, as well as to coordinate criminal activities such as drug deals. In May of this year, nine prison employees at Rimutaka were suspended for suspected misconduct, which involved the smuggling of cellphones into the facility.

The decision made by Corrections to discontinue the use of jammers is in line with the concerns expressed by Roger Brooking, a criminologist and drug and alcohol counsellor, who has consistently questioned the effectiveness and cost of this technology.

He expressed that their performance is inadequate and has consistently been so.

Prisoners have shared with me that they have identified specific areas in the prison where the signal blockers does not work as intended. This loophole has enabled inmates to make illicit phone calls for activities like drug transactions or personal conversations.

A cell phone jammer is a piece of equipment that can disrupt the reception or transmission of cell phone signals by creating interference at the frequency bands used by cell phones. This interference results in the absence of signal or a significant deterioration in signal quality. Although cell phone jammers can be utilized in diverse settings, they are primarily deployed in areas where silence is anticipated or mandated.

Techopedia delves into the topic of cell phone jammers.

A cell phone jammer is made up of:

• Antenna


• Voltage-controlled oscillator


• Tuning circuit


• Noise generator


• Power supply


• RF amplification

When a cell phone jammer is active, the majority of cell phones experience a lack of network signal. Conversely, when the cell phone jammer is turned off, the cell phones regain their ability to connect. It is worth noting that cell phones operate on distinct frequencies for transmitting and receiving data. As a result, most cell phone jammers obstruct either one or both of these frequencies, thereby effectively preventing communication on both ends.Cell phone jammers function according to the principles akin to those of jammers used for blocking radio communication. They disrupt either the frequencies from the cell phone to the base station or from the base station to the cell phone.

Cell phone jammers find utility in the arsenal of law enforcement and military personnel to restrict and disrupt communication in different circumstances. To counter corporate espionage, specific organizations employ these jammers to impede communication within sensitive areas. Furthermore, portable cell phone jammers are utilized by certain individuals to prevent others from using their phones in close proximity.

Cell phone jamming is prohibited in numerous countries, including the United States, except for specific military and law enforcement purposes. The United States has implemented some of the world's most rigorous laws regarding cell phone jammers, making their sale or purchase illegal. However, in countries like Mexico, the use of cell phone jammers is allowed in public areas like hospitals. It is important to acknowledge that different countries have varying regulations concerning the use of cell phone jammers.

The legality issue surrounding cell phone jammers stems from three specific reasons

Cell phone jammers are designed to prevent you and others from reaching out to 911 and other emergency services. Moreover, they can jeopardize public safety communications and interfere with various other types of daily communication.

In this article, you will find an explanation of how signal jammers operate, the legal restrictions surrounding their use in the United States, guidelines for addressing instances of jammed authorized communication, and information on how Cellbusters can address any queries regarding cell phone jammers.

Dealing with Jammed Authorized Communication: Recommended Measures

Is it possible that a signal jammer is causing the interference? Poor network connections can be attributed to various factors, one of which could be signal jammers:

1. faulty equipment


2. physical obstructions that block the signal


3. lawful devices that are operating on the same frequencies

Before initiating an interference complaint through the FCC Consumer Complaint Center, it is important to troubleshoot any equipment and connectivity issues as per the guidelines provided by the manufacturer and service provider. In addition to referring to the owner's manual and contacting the company's technical support, conducting an online search for your device/model and the specific issue can help in identifying or ruling out potential causes.

A cell phone jammer is a device specifically designed to obstruct the reception or transmission of cell phone signals by generating interference within the frequency bands utilized by mobile phones. By transmitting signals on the same radio frequencies as cell phones, the jammer disrupts the communication between the phone and the nearest cell phone base station, effectively preventing any phones within its range from receiving signals.

When opting for a cell phone jammer, it is worth considering certain factors:

• What is the desired coverage area for the cell phone jammer?


• Do you require a compact and inconspicuous cell phone jammer that can be easily carried in your pocket?

The utilization of cell phone jammers presents numerous advantages, whether you seek to silence individuals in close proximity within public areas or suppress the usage of cell phones in your business or educational institution. However, it is imperative to conduct thorough research in advance to guarantee the purchase of a signal jammer that effectively fulfills your specific requirements.

When searching for cell phone jammers for sale, you should take the following into consideration…

1. How much time has the vendor spent in the business industry?


2. Is the vendor providing a wide range of products, or are they only selling signal jammers?


3. What extent of space do you require the cell phone jammer to encompass?


4. Are you looking for a discreet (pocket-sized) cell phone signal jammer?


5. Are you looking for a cell phone jammer that is tailored to your application, offering options such as portability, fixed installation, or vehicle-based usage?


6. Are you interested in a novelty product or a legitimate cell phone signal disruptor?
