jammer

As technology becomes more and more advanced, the use of the Internet is becoming more and more popular for the modern generation. In particular, with the invention of 5G and smartphones, the Internet has ushered in a "golden age." Wi-Fi life has now become everyone's life. It changed the world. The topic about the advantages and disadvantages of WIFI has been very hot. Some people think WIFI makes the world a better and more convenient place; We should use WIFI extensively in our life. While some people think that WIFI and smart phones are not appropriate for some special occasions.

To prevent interference, you know you need a signal jammer to improve your quality of life. While many countries make it illegal to use a cell phone blocker for personal use, be sure to check your local laws before you buy one from a professional blocker online store, and if the laws in your country allow it, you will be entitled to a useful jammer device.

Whether in a class, conference room, presentation, or religious service, calling at the wrong time can be a huge distraction. Cell jammers can stop these calls from coming in the first place. This is what we call preventing interference and unwanted calls or blocking phone noise by using cell phone signal jammers; You will have the power to stop them.

Have you ever been in a situation like this? The phone rang for a long time and no one cared about the interruption. You say loudly, "Please cover your phone." The result is that no one answers you. The unfortunate reality for any large group is that telling people to mute their devices just doesn't work. There will always be a small percentage of people who will leave their devices on for whatever reason.

How to use cell phone blocker to restrict students from using cell phone?

The use of mobile phone signal blockers is worthy of recognition, whether it is to reduce the interference of mobile phones on students' learning, improve the quality of students' learning, or to facilitate school management. You know the truth is that many schools and colleges have installed several different types of cell phone signal blockers so that parents and teachers can let students and children play with their phones. Some students expressed support. Because the use of mobile phones will make mobile phone noise immediately disappear, creating a quiet environment.

The NFL and federal law enforcement are on high alert for unauthorized drones after one caused a play stoppage at a playoff game two weeks ago.

Super Bowl LVIII will feature a tough defensive scheme that has nothing to do with a football. This one is about stopping drones.

The NFL and federal law enforcement officials are taking a hard line Sunday to keep players and fans safe from unauthorized drones at Allegiant Stadium in Las Vegas where the Kansas City Chiefs will play the San Francisco 49ers.

Unapproved drone flights have become a persistent problem for the NFL, as well as for other sports leagues and large public gatherings. The NFL said there were about 2,500 drone incursions near stadiums during the 2022-2023 season, an increase of about 90% from a year earlier.

The flights have sometimes encroached on televised broadcasts, including two weeks ago at the AFC championship game in Baltimore when an unapproved drone violated the restricted airspace. Federal prosecutors later charged a Pennsylvania drone pilot who said, according to the FBI, that he wasn’t aware of the flight restrictions.

Possible criminal charges and civil penalties await anyone trying something similar Sunday, officials said.

“So please leave your drone at home,” Cathy Lanier, the NFL’s chief security officer, said at a news conference Wednesday.

Most of the drones are operated by hobbyists seeking aerial video, according to experts, but especially at a high-profile event such as the Super Bowl, authorities said they’re also looking out for people with more nefarious intentions.

Homeland Security Secretary Alejandro Mayorkas said the incident two weeks ago was a warning.

“It does not require much imagination to understand the significant threat such an incident could pose,” he said at the news conference Wednesday. Although no one was hurt in that incident, he said, “what happened in Baltimore underscores the vital importance of the mission.”

Mayorkas added that there were no known credible specific threats to the Super Bowl or Las Vegas.

Federal law enforcement designates the Super Bowl as a top-tier security event, on roughly the same level as a presidential inauguration ceremony or a visit by the pope. Allegiant Stadium, where the teams will play, has a capacity of about 65,000 people.

Any stadium’s defense against drones has multiple layers, said Mary-Lou Smulders, chief marketing officer for Dedrone, a Virginia-based company. Its drone countermeasure technology is in use by the Las Vegas Metropolitan Police Department, which covers Las Vegas and its major stadiums.

“Like any security issue, the more layers you add, the safer you are,” she said. “The same applies to airspace security.”

The first layers, she said, are all designed to detect and track drones using at least three types of technology: radio-frequency sensors, cameras and radar. They have different strengths, she added: Radio-frequency sensors can distinguish between drones and other objects better than radar, while radar has a longer range and a camera can help determine if a drone is carrying a payload.

With a camera, Smulders said, “the most interesting thing to ask is: Is it carrying a payload, yes or no?” If it were, that “would dramatically affect your security posture.”

A second set of layers is designed to interfere with a drone’s flight, she said: “cell phone jammer jamming” or cutting off the radio communication between a drone and its pilot; hacking into a drone to take over control; and locating the pilot on the ground and arresting the person.

drone jammer Jamming and hacking are not usually available as security tools for an NFL game. Federal law restricts who can interfere with a drone’s flight, and in the United States, only a few government agencies including the Department of Homeland Security and the FBI have the authority to do so. Congress is considering legislation to change that but, for now, the federal government provides agents for high-profile events like the Super Bowl but not for a game on any given Sunday.

At a regular season game in Baltimore in November, play was delayed twice because of drone activity.

The NFL game stoppages are helping raise the profile of drone countermeasures, a growing industry that experts say will become more important as drone technology improves and becomes cheaper.

Allegiant Stadium has one advantage over Baltimore’s: It’s a domed stadium, with a roof to shield the game from anything overhead. But it’s not completely enclosed, Smulders noted: The stadium has 80-foot walls that are retractable if weather allows. The doors have usually been closed during games.

Still, the NFL is on higher alert for drones than it used to be. In 2017, a California man used a modified drone to drop leaflets on the 49ers stadium, authorities said. He then drove to nearby Oakland and did the same at a Raiders game. He later pleaded guilty and was sentenced to probation.

For Sunday, the Federal Aviation Administration has banned drones within a radius of 30 nautical miles (about 35 miles) of the stadium beginning one hour before kickoff. There have also been restrictions in place for additional events in Las Vegas the past few days.

Lanier has previously told NBC News that the NFL had a close call at the Super Bowl in Atlanta in February 2019, when an FBI team spotted a drone just before six Air Force F-16s were set to conduct a flyover before the game. The F-16s flew at a higher altitude to avoid a possible collision, she said.

Illegal GPS signal jamming can disrupt local GPS devices and cell phone towers, according to UK reports.

Findings from the Sentinel study presented at the GNSS Vulnerability 2012 conference at England's National Physical Laboratory on February 22 revealed a rise in jamming incidents, as reported by TechWeek Europe. Over a span of six months, roadside monitoring stations documented a total of 60 violations.

Sean Gallegher, writing in Ars Technica, reported on the dangers of interrupting GPS signals. Cell phone systems and even electrical grids rely on GPS signals for time-keeping. Jammers built for auto use to obscure location can affect other devices from 100 yards away and more. Powerful jammers can disrupt signals as far away as 32 kilometers. Yes, jammers have caused problems at airports already. They are illegal to use, but legal to own, in the UK.

Surprise

I had no idea little GPS jammers could cause so much havoc though.

First hand

I know a guy who bought that exact jammer in the picture. I think it was a little over $100 shipped from China. It works. It kills my AT&T iPhone dead. It kills his Sprint phone. It killed everything except one device he's ever tried to test with.

A word of caution has been issued by the Los Angeles Police Department to the residents regarding the utilization of WiFi jammers by criminals. These jammers are being employed to easily deactivate "connected" security cameras and sirens. It is important to be aware that these jammers can be purchased at low prices from platforms like Amazon.

Los Angeles news station KTLA5 has highlighted a concerning trend where tech-savvy thieves are utilizing WiFi jammers. These small devices have the ability to confuse wireless devices and inundate them with excessive traffic. By doing so, these criminals can gain access to homes without triggering any alarms. This raises questions about the vulnerability of affordable housing to security devices like Ring and Eufy.

According to a recent report by Tom's Hardware, instances of criminals employing WiFi jammers have been documented for quite some time. These jammers can be conveniently purchased online for a modest price of $40.

From a legal perspective in the United States, their use is considered illegal...

In a 2020 FCC alert, it was stated that the deliberate use of phone jammers, GPS blockers, or other signal jamming devices to block or interfere with authorized radio communications is considered a violation of federal law.

Despite the warnings, it appears that they were disregarded. Recently, law enforcement in Minnesota uncovered that nine robberies within a six-month period were linked to the use of wifi jammers. Luckily, the thieves are still opting for non-violent methods and focusing on empty houses.

In light of the current circumstances, the Los Angeles Police Department is suggesting that homeowners opt for hardwired alarm systems instead of relying solely on WiFi. Furthermore, they are urging residents to ensure their homes are well illuminated during the night.

The LAPD further suggests that you take precautions to keep your departure from your residence for an extended period of time confidential.

Cell phones serve as two-way radios that communicate via cell towers. cell phone jammer operate by emitting a strong signal on the same frequencies utilized by mobile devices, effectively blocking communication between the device and the cell tower. As a result, the mobile device loses connectivity and shows "No Network" on the display.

Cell phone jammers prevent and disable any mobile phone communications from entering specific areas of a building or open space to

1. Take proactive steps to counter industrial espionage by implementing stringent measures to deter the use of mobile devices as eavesdropping tools or for unauthorized photography purposes.


2. The endeavor to combat terrorist threats encompasses the mitigation of actions such as remotely triggering explosive devices in areas of heightened vulnerability.


3. The eradication of public nuisances in establishments such as movie theaters, restaurants, and churches is essential.

This item is available in a range of sizes and shapes. You can find pocket-sized versions as well as larger ones. Moreover, some models are cleverly disguised as regular cell phones or briefcases.

Things to consider before buying a cell phone jammer:

• What is the effective interference range (more than 10-50 meters)


• Which cellular systems can it block (cdma in north america, gsm in europe and asia, tdma, 4G, 3G, pcs, dcs or all?)


• How many cellular systems (cdma etc..) it can block simultaneously (low-end models can only block 1 type at a time, while more complex models will block multiple systems at a time)


• Appearance: Regular device or one disguised as another type of device?


• Dimensions and weight

Cell phone calls are more and more being blocked by technology initially created to assist security personnel in preventing unauthorized listening and stopping phone-activated explosive devices.

The reporters were the first to notice the issue. While they were busy covering the weddings of prominent individuals, they found themselves unable to contact their editors. Curious about the lack of cell phone signal at Sacred Heart, they inquired with the priest. His response pointed to Israeli counterintelligence as the reason behind the connectivity problem.

Israeli-manufactured cell phone blocker, resembling paperbacks in size, have discreetly been placed among religious artworks depicting the Madonna and statues of saints in four churches in Monterrey.

The disruptive multicolored noise of ringing mobile phones is being more and more effectively blocked in various places, such as religious sanctuaries, India's parliament, Tokyo theaters, and commuter trains, thanks to devices initially created to assist security forces in preventing eavesdropping and stopping phone-activated bombings.

The installation of signal blocker in the Indian parliament came after repeated requests for politicians to switch off their cell phones were disregarded, leading to frequent interruptions during legislative sessions.

Italian universities have implemented the use of blockers as a response to the issue of tech-savvy teenagers cheating on exams by sending text messages or capturing images of test materials.

The four Roman Catholic Churches in this northern city have recently adopted the devices provided by Netline Communications Technologies Ltd., a Tel Aviv-based company. These devices were imported by an insurance salesman as a personal favor for a priest.

The Rev. Juan Jose Martinez, a spokesperson for the archdiocese, expressed that there are still numerous individuals who fail to comprehend that attending Mass entails participating in a sacred moment with God. Regrettably, the utilization of these small devices became an unavoidable necessity.

These devices, which were acquired at a cost of approximately $2,000 each, have the capability to be activated remotely and emit radio frequencies at a low level. Their purpose is to disrupt cell phone signals within a radius of 100 feet.

Cell phone users often encounter a message stating "no service" or "signal not available" on their devices.

Wedding bells

The Sacred Heart church in Monterrey, a baroque temple popular among Mexico's upper class for weddings, had their blockers purchased by church officials two years ago.

Bulmaro Carranza, a parish clerk, mentioned that during weddings, cell phones would ring every five minutes. This posed a significant issue, as there were instances when even the groom would neglect to silence his cell phone.

The devices remained unnoticed for several months until journalists, who were covering the weddings, started expressing their dissatisfaction with the constant malfunctioning of their cell phones.

Carranza mentioned that ever since news about the signal blocker spread, priests from various parts of Mexico have been reaching out to inquire about acquiring them.

Prior to each Mass at Sacred Heart, a device positioned at the church entrance and another near the altar are activated. Nevertheless, the clergy consistently emphasize the importance of switching off mobile phones before the commencement of the services, with the aspiration that proper cell phone etiquette will gradually become more widespread.

Martinez mentioned that wealthier parishioners also frequent The Rosario, San Juan Bosco, and Our Lady Queen of the Angels, among other Monterrey churches with the devices.

Martinez emphasized that many people consider the cell phone a necessity, yet this should not excuse them from practicing good manners and showing respect for sacred locations.

Margarita Escobedo, a devout Catholic who attends church services at least twice a week and actively volunteers at the San Genaro church, expresses her willingness to embrace the use of jammers within her parish. She believes that the increasing presence of cell phones has become a bothersome distraction, and thus, welcomes any measures that can alleviate this nuisance.

Escobedo stated that individuals who bring cell phones to church are lacking in commitment to God. He emphasized that the sounds of birds chirping or techno music can be highly disruptive during prayer.

The individuals are being accused of engaging in computer criminal activity for reportedly interfering with the network at the behest of their acquaintances.

Two teenagers, aged 14, have been accused of disrupting their school's Wi-Fi system in order to avoid taking exams, as reported by authorities on Monday.

NJ.com reported that high school freshmen in New Jersey are facing charges related to computer criminal activity and conspiracy to commit such acts. Authorities were alerted by school officials last Thursday following a series of Wi-Fi network crashes over the course of a week.

Capt. Dennis Miller, as reported by NorthJersey.com, stated that school authorities at Secaucus High School contacted the Secaucus Police Department to inform them about two students who were involved in a "plot to intentionally disrupt the school's WiFi service whenever requested."

The identities of the individuals have not been disclosed due to their status as minors. They have been reunited with their parents and are anticipated to attend a hearing at the juvenile family court in Jersey City, the specific date of which remains undisclosed.

On Monday, Schools Superintendent Jennifer Montesano announced that the Wi-Fi has been restored and is functioning properly. Although she did not provide specific information, she did mention that an investigation identified two students who potentially played a role in the disruption of our system.

How did they do it?

Several students informed NJ.com that they suspect the boys utilized a Wi-Fi interrupter program or application to overwhelm the school's routers with traffic in a denial of service (DoS) attack. This attack resulted in the network failing when students attempted to access it for classwork or online exams.

The news outlet interviewed a student at Secaucus High School who mentioned that she became aware of the Wi-Fi issue after a friend informed her that one of the suspects had been asked to disrupt the signal during an exam.

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

One of the boys engaged in this behavior as a means to evade tests and similar obligations. Additionally, he did it on behalf of his friend, so that she could avoid taking a test during the class. Undoubtedly, it was a substantial 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:

I found it astonishing that a child of our age, or near our age, could accomplish such a task.

The manipulation of individuals' education is occurring, yet it is not causing harm to anyone.

Concerning the initial point, it is advisable for those students not to be overly influenced by their peers' supposed technological expertise. Despite the fact that gsm jammer are prohibited from being marketed, sold, or utilized in the United States - with the exception of authorized, official use by the federal government - they can easily be purchased online for a few hundred dollars.

With regards to nobody getting hurt when Wi-Fi crashes, the Federal Communications Commission (FCC) begs to differ. When you use a signal jammer, you’re jamming critical communications, the FCC points out in its jammers FAQ:

Jammers present a significant threat beyond mere annoyance; they endanger public safety by obstructing the transmission of vital emergency communications. cell phone jammer fail to differentiate between casual conversations and urgent calls for help to loved ones or emergency services. Likewise, GPS and wifi jammer intentionally disrupt essential communication services, both routine and critical.

Several years ago, an incident occurred where a man was charged with a felony for deliberately disrupting the phone signals of his fellow commuters. This action was driven by his annoyance towards their conversations.

It is possible that no one was injured as a result of the school Wi-Fi jamming, however, it is crucial that children do not develop the belief that this is a harmless joke. The consequences are not trivial, and they can be quite serious.

Utilizing technology, thieves have successfully eluded surveillance cameras in a number of home break-ins, as per CMPD's findings reported by WBTV.

The act of cell-jamming takes place when someone employs a gadget to obstruct radio or wireless signals.

As per the Federal Communications Commission, it is against federal law to purposefully employ a phone jammer, GPS blockers, or any other signal jamming device to disrupt authorized radio communications. It is crucial to understand that this prohibition applies universally and does not provide any exemptions for usage within a business, classroom, residence, or vehicle.

Cell-jamming might take place from a device about 30 feet away from the intended target, or home surveillance cameras.

Surveillance footage from a south Charlotte community reveals a suspect discreetly moving through a yard at night. Nevertheless, it should be acknowledged that not all incidents have been documented on camera.

According to John Shocknesse, VP of Customer Operations for CPI Security, the presence of wireless devices opens up opportunities for interference, making it crucial to take preventive measures.

Within a matter of seconds, a person could be captured on camera, but the use of cell-jamming technology allows for their immediate disappearance with just a single action like flipping a switch or pressing a button.

CMPD has acknowledged that this matter has arisen during a number of home break-ins in south Charlotte.

The absence of such activity has been noted by Shocknesse, who emphasized the importance of being aware of it and having access to cutting-edge technology.

WBTV questioned him regarding the devices that exhibit higher susceptibility to cell-jamming.

According to Shocknesse, the significance arises when dealing with older wireless devices that do not possess encryption.

According to him, modern security and surveillance systems come equipped with superior technology, including encryption, resulting in increased security measures.

Stressing the importance of cameras and onboard recording, Shocknesse highlighted the value of having memory devices to capture and preserve footage in case of any incidents.

Furthermore, he suggested that the optimal approach to thwart cell-jamming is to utilize state-of-the-art technology that includes encryption, as well as utilizing a wired device rather than relying on Wi-Fi.

To reduce the risk of home invasions, it is advisable to adhere to basic precautions such as keeping the surroundings well-lit, using alarm systems, and maintaining bushes at a height of no more than three feet.

According to authorities, a gang of thieves has been outmaneuvering sophisticated devices in various locations across Los Angeles.

On March 4, the Los Angeles Police Department released a statement alerting the public to a group in Wilshire employing Wi-Fi jamming technology to neutralize surveillance cameras and alarm systems that are Wi-Fi-enabled.

The current wave of tech-savvy robberies in California is indicative of a larger-scale "smart" crime wave that is sweeping the nation. Similar alerts were issued by the police in Minnesota and Connecticut last year, warning residents about groups of thieves proficient in Wi-Fi jamming techniques. These incidents serve as just a glimpse into the multitude of similar cases.

According to KARE11, criminals can readily purchase Wi-Fi signal jammers jamming devices at a low cost, despite the Federal Communications Commission's ban on them. These devices do not directly disable other devices but rather overload the network they are connected to.

According to cybersecurity expert Mark Lanterman, these devices are designed to disrupt radio transmitters, causing traffic jams that prevent legitimate communication.

According to his advice, if you intend to employ a Wi-Fi camera for your front door, it might be worth considering the use of a hardline camera inside your home. Wired cameras that are connected via Ethernet cables do not rely on Wi-Fi networks and are immune to disruptions caused by a wifi jammer.

The Los Angeles police highly advises the use of hard wired burglary alarm systems.

According to Tom’s Hardware, smart technology may play a role in both the problem and the solution. Officials suggest the use of timers or smart home devices to give the appearance of someone being at home while you are away. Additionally, some smart home technology can alert users of any interruptions in the signal or connection.

Tom's Hardware suggests connecting surveillance devices to your device for storing camera footage, rather than solely relying on a cloud storage system. By doing so, you can ensure that even during a Wi-Fi disruption, the footage will be saved and accessible.

Individuals are urged by the LAPD to stay cautious by locking their doors, asking neighbors to keep an eye on their surroundings while they are away, and informing law enforcement about any suspicious activity, particularly concerning vehicles with temporary or dealer plates.

Wilshire Park is located in Central Los Angeles.

In today's society, mobile phones have become an indispensable tool for communication in people's daily routines. However, there are specific situations where mobile phone signal jammers play a crucial role. This article presents a comprehensive analysis of mobile phone signal jammers, covering their technical principles and application scenarios. By delving into these aspects, readers can develop a deeper comprehension of the technology and the valuable applications associated with it.

How mobile phone signal jammer works

The primary operational principle of the mobile phone signal jammer is to transmit signals at the same frequency as mobile phone communication, but at a higher power level to disrupt the original signal. This disruptive signal will overpower or drown out the signal normally received by the mobile phone, preventing the mobile phone from communicating with the base station as intended, ultimately achieving the goal of signal blocking.

Jammers emit signals that disrupt specific frequency bands, commonly targeting GSM, CDMA, 3G, 4G, and even the newest 5G network bands.

cell phone jammer have different coverage ranges depending on their power levels, with increased power leading to wider coverage.

Types of cell phone signal jammers

Designed to be easily carried, this portable jammer is perfect for personal or small-scale use, including conference rooms and small offices.

Tailored for use in schools, examination rooms, prisons, and similar settings, this high-power jammer offers a wide range of coverage.

Personalized jammers are crafted to suit the specific demands of different environments, such as military bases, government facilities, and other secure areas.

The principle and application of GPS signal jammer

GPS signal blockers emit electromagnetic waves with specific frequencies that disrupt signals transmitted by GPS satellites, causing GPS receivers to struggle in interpreting satellite signals. This approach mirrors that of conventional electronic jamming devices, albeit with a focus on 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.

Typically, portable gps jammer serve the purpose of ensuring personal privacy, whereas fixed jammers are predominantly utilized in professional sectors such as the military and government, offering substantial power and an extensive coverage area.

The utilization of GPS signal jammers by the military enables them to disrupt enemy navigation systems, effectively hindering their ability to accurately determine positioning and navigate.

There are those who may opt to employ GPS signal disruptors in order to block location tracking and ensure the protection of their personal privacy.

The commotion surrounding the AIIMS entrance exam may have caught many off guard, however, the city university has implemented precautionary steps to prevent such occurrences. While certain universities have opted for jammers at entrances, others have chosen metal detectors or security guards. Nevertheless, only a few have implemented all of these measures. Jammers are effective in detecting mobile signals and deterring students from engaging in unfair practices cell phone jammer.

Ms. Kang, the director of Punjab College of Technical Education (PCTE), mentioned that two years ago, they implemented jammers in the examination hall during a period when approximately 900 students were sitting for their exams. She further emphasized that the utilization of a disruptor could effectively address the concerns of all individuals by disabling their cellular network coverage.

HS Singha, the director of Guru Nanak Institute of Management and Technology (GNIMT), mentioned that the installation of two jammers on the campus three years ago effectively reduced cheating incidents. Additionally, regular physical verifications are conducted to prevent students from carrying phones with them wifi jammer.

MS Saini, the principal of Guru Nanak Dev Engineering College (GNDEC), expressed concern over the fact that some students resort to unfair practices in order to achieve higher grades. He highlighted the challenge of conducting physical verification due to the enhanced capabilities of students, leading to the installation of 11 jammers on campus. Furthermore, the college has implemented the use of three metal detectors and enhanced security measures at the entrance gates.

Pawan Kumar Gupta, the head of Ludhiana College of Engineering and Technology, mentioned that they had implemented five jammers and two metal detectors on the premises approximately three years ago. He emphasized that the widespread adoption of such devices in educational institutions could significantly reduce the chances of cheating through technological methods signal jammer.

Can mobile jammers in colleges stop cyber crime?

The proposed ban on mobile phones at universities in the city has left students feeling apprehensive. The Maharashtra government's higher and technical education department is considering this measure to address the issue of cybercrime within university campuses.

Nevertheless, students expressed their dismay over what they perceived as a violation of their freedoms. Lala Atole, a student at ILS Law School, argues that the suggested prohibition lacks logic gsm jammer.

"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?"

Vedang Bhagwat, a student from Garware College, inquired about the situation. Despite students voicing their discontent with the decision, there is a lack of consensus among university officials regarding the proposal. The authorities are considering the installation of jammers in classrooms, but are hesitant to implement them campus-wide.

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, the vice-chancellor of Neswadia Business School, mentioned that disruptors are not a viable solution due to the high number of out-of-town students in Pune whose guardians often need to get in touch with them.
