Prior to assessing the effect of a mobile phone signal jammer on laptop Internet access, it is crucial to comprehend the interference frequency band utilized by the jammer and the frequency band employed by laptops to access the Internet.

First of all, if the interference frequency band of the mobile phone signal jammer overlaps with the frequency band used by the laptop to access the Internet, it will affect the laptop’s Internet access function. Let’s first take a look at the interference frequency band of cell phone jammers. Due to the wide signal coverage of domestic operators and the wide range of application standards, mobile phone signal jammers must achieve the effect of blocking the entire network. Generally, they will effectively block interference for 2G, 3G, 4G band signals, WiFi, GPS, and Bluetooth signals.

Having identified the frequency bands that the cell phone signal blocker described above can interfere with, let us now turn our attention to the frequency bands that laptops utilize for Internet connectivity.

Laptops generally have two ways to access the Internet, one is wired Internet access, that is, Ethernet network port Internet access, and the other is wireless Internet access. At present, mobile phone signal jamming device cannot block or interfere with wired Internet access, so here we mainly describe the frequency bands for laptop wireless Internet access. According to the current classification of laptops on the market, wireless Internet access supports single-band and dual-band. The so-called single-band refers to only supporting WiFi2.4 frequency band to connect to the Internet, while dual-band supports WiFi2.4 and WiFi5.8 frequency bands to connect to the Internet. Most laptops only support single-band, and some that are more expensive or have more conscientious configurations will be equipped with dual-band Internet access.

The interplay between signal blockers and laptop computers’ working frequency bands becomes apparent to keen observers, who can readily recognize the potential disruption of laptop Internet access by mobile phone signal jammers.

Detailed requirements are broken down into the following situations:

1.The mobile phone signal jammer does not have a WLAN module and will not affect the wireless Internet access of laptops;

The mobile phone signal jammer supports the WiFi2.4 frequency band, which affects the wireless Internet access of single-band laptops but does not affect the wireless Internet access of dual-band laptops;

The mobile phone signal jammer supports WiFi2.4 and WiFi5.8 frequency bands, which will affect the wireless Internet function of the laptop.

Through the comprehensive understanding gained from the preceding explanation, we have obtained a clear answer regarding the potential interference of a mobile phone signal jammer on a laptop’s Internet access. It has been established that the laptop’s wireless Internet connectivity may be disrupted by the operation of a signal jammer. To ensure uninterrupted access, customers who utilize signal jammers for shielding purposes should consider equipping their laptops with Ethernet cables to establish connections with external network offices. This approach will enable them to achieve optimal performance in both aspects.

Advantages of cell phone signal jammer

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

• Prevent industrial espionage using mobile devices as eavesdropping devices or for taking photos (cameras)
• Counter terrorist threats, such as remotely detonating bombs in high-risk areas
• Eliminate public nuisance in places such as cinemas, restaurants and churches

How cell phone blockers work

Cell phones are two-way radios that communicate via cell towers. cell phone jammer work by sending a strong signal on the same frequency used by mobile devices to effectively interfere with communication between the device and the cell tower. The result is that the mobile device does not work and “No network” is displayed.

Physical description of cellular jammer

It comes in different sizes and shapes. Some are pocket sized, some are bigger. Some masquerade as plain phones or briefcases.

Precautions before buying a mobile phone jammer:

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

Which cellular systems can it block (cdma in North America, gsm, tdma, 4G, 3G amplifiers, pcs, dcs or all?)

• How many cellular systems can it block simultaneously (cdma, etc…) (Low-end models can only block one type at a time, while more complex models block multiple systems at once)

Indoor 3G cell phone signal blocker

As we all know, for a certain purpose, in order to achieve the ideal state, now mobile phone signal blockers are used to help people achieve the purpose, and in the various types of mobile phone signal blockers sold on the market to buy one that can meet your requirements is the best choice. For those who are looking for a signal blocker that can cut off 3G cell phone signals and also has adjustable features, they can take a look at this “4 antenna Adjustable Cell Phone Signal” remote control jammer that will be introduced here soon.

As we all know, in different situations people may need to cut off the signal of different frequency bands, if this is the case, gain one with adjustable function may be a good choice, because it allows you to choose the interference frequency band you want, and since this 3G mobile phone signal blocker design has adjustable buttons, so you can easily reach the target. In addition, since this is a high-power 3G phone jammer and is designed with 4 antennas, it can also easily cut off 2G 3G phone signals at the same time. This adjustable 3G mobile phone signal blocker features a high-power design that interferes up to 40 meters depending on the signal strength in a given area.

More importantly, the 3G mobile phone signal blocker is also designed with a good cooling fan system, so that the 3G mobile phone signal blocker always maintains a good working condition, without producing high temperature harmful to the 3G mobile phone signal blocker itself. Therefore, one aspect that people will also consider is the application field of this high-power 3G mobile phone signal blocker, if so, you do not have to worry about this high-power 3G mobile phone signal blocker, you can easily use it in churches, churches and other places, theaters, concert halls, classrooms, libraries, banks, museums and other places do not allow loud talk, But some people can’t resist talking on their mobile phones, and other places where the use of mobile phones is not allowed, this 3G mobile phone signal blocker can also be used.

4G cell phone signal blocker

The full name of this handheld signal blocker is “6 antenna Handheld 3G 4G full frequency mobile Jammer”, this is a 3G 4G full frequency mobile jammer, with 6 antennas, in addition to cutting off 3G, 4G(LTE) and 4G(Wimax), the jammer can also block normal 2G mobile signal at the same time. Such as CDMA, GSM, DCS and PCS mobile phone signals. And with a portable design, it is lightweight and can use a rechargeable battery as a power source, so this portable 3G 4G signal jammer is easy to remove when needed.

So while this is a handheld 3G 4G phone jammer, it’s also designed with a high-quality cooling system so you can use it without worrying about the temperature. In addition, this handheld 4G signal blocker has also been designed with an on-board charger, so that it can easily be used in the car, so for people who need to use this handheld signal blocker in the car, just choose this one. . Therefore, this handheld 4G mobile phone blocker is also designed with selectable buttons so that you can decide the interference frequency band according to the actual situation you are in.

This is a common misconception. Many people tend to think that in an emergency, cell phone jammer do block emergency calls. They couldn’t be more wrong.

Did you know that your regular smartphone can still make emergency calls even without a SIM card installed? Most cell phones are designed so that if you run into trouble and can’t connect to the network provider you signed up for, you can still call 911 and other emergency services.

As a precautionary safety measure, you can always connect to emergency services. This is the international standard. For example, in the United States and other countries, there is a law that requires cell phones to be able to make emergency calls even in the event of a complete shutdown of service.

Similar to roaming services when you are abroad, your phone can be connected to any other available network to make emergency calls. 911 in the US, 999 in the UK and 112 in Europe will override any roaming listings or unregistered ones and will force the phone to try to connect to any network it can receive.

The basic understanding is that if you have a cell phone, all providers must accept 911 calls and forward them to a call center. Mobile phones are designed to allow calls to local emergency numbers using any available and compatible network, even without a subscription to the provider (i.e. SIM card via GSM phone).

Since most jammers emit low-power signals, the following bands will still be able to communicate with cell towers and will not be blocked (in most cases) anyway:

Police band

EMS Band (Emergency Medical Services)

Fire band

Cellular jammers can prevent teenagers from negligent driving

This is a big concern for many parents. Knowing that your son or daughter is driving will always worry you. Today, most accidents are caused by distraction while driving using a cell phone. The number of deaths caused by distracted driving is staggering.

Cellular jammers, which are installed in vehicles and automatically activated once a certain speed limit is reached, will go a long way towards reducing these numbers and allowing for more accurate and careful driving. No more Facebook or Instagram; No more WhatsApp messages while driving. We could all be safer on the roads.

Considering everything in this article, it’s clear that we’re in favor of legalizing the sale of cell phone signal jammer. Although they are illegal, there is great public interest in them and their use has increased over time. In this technological world, the need for such devices cannot be ignored.

The demand exceeded our expectations, and more and more people came to us for solutions to this never-ending problem called the mobile phone.

Currently, we are renting a house. The neighborhood becomes very noisy in the late evening, well past midnight, as our neighbors play loud music.

Contacting the police proves to be of no avail. Despite my multiple attempts to seek their intervention, their assurances to send assistance remain unfulfilled. Consequently, I initiated an investigation into signal blockers that solely disrupt wifi signals, not cellular ones. Fortunately, I stumbled upon a device that seems to perfectly meet my requirements.

I must confess that I was initially skeptical about their payment processes. Nevertheless, I soon came to the conclusion that their product was exactly what I had been in search of.

I submitted the payment and waited with patience. The standard shipping policy outlines a delivery period of 7 to 15 days.

After the passage of 15 days, we were furnished with the tracking information. It then proceeded to clear the port and was subsequently taken into the possession of DHL for transportation. In a remarkably short period of 2 days, the package arrived at its designated location.

Once I had taken it out of the box, I proceeded to attach the antennas and connect the charger. It was a pleasant surprise to find that the battery had been fully charged.

We endured a few days of sleep disturbance caused by the unwanted music before taking action. Retrieving the device from the nightstand, I activated it. It is important to note that these neighbors live a few houses away from us. Surprisingly, within a few seconds, the music ceased. Subsequently, I overheard people discussing the issue at hand. In order to investigate further, I left it playing for a solid 20 minutes. Finally, I switched it off and retired to bed.

The jammer device experienced a loud bang and emitted smoke when I charged it for the first time, resulting in irreparable damage. After contacting the company, I was provided with an RMA return number and directed to ship the device to China for repair or replacement. The return shipment cost me an extra $25, on top of the initial payment of over $350 for the device. It took a significant amount of time to receive the restored radio signal jammer.

Indeed, the cell phone signal jammer is a trustworthy business, as you inquired. It appears that some reviews are untrustworthy. I have tangible proof to support my statement.

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.

Security forces are utilizing technology originally intended to prevent eavesdropping and thwart phone-triggered bombings to block ringing cell phones.

The reporters were the ones who first became aware of the situation. While they were engaged in reporting on the extravagant weddings of celebrities, they discovered that their cell phones were not functioning at Sacred Heart. Upon questioning the priest about this issue, they learned that Israeli counterintelligence was the cause of the disruption.

In Monterrey, four churches have inconspicuously integrated Israeli-made cell phone blocker, which are compact and resemble paperbacks, amidst their collection of religious artwork featuring the Madonna and statues of saints.

The loud and colorful ringing of cell phones is increasingly being stopped in places like religious sanctuaries, India’s parliament, Tokyo theaters, and commuter trains, thanks to devices that were originally developed to assist security forces in preventing eavesdropping and stopping phone-triggered bombings.

Jammers were put in place in the Indian parliament as a response to politicians consistently ignoring calls to power off their cell phones, causing disruptions in legislative proceedings.

After uncovering instances of exam cheating through text messaging or photographing test papers, Italian universities decided to introduce blockers as a preventive measure.

After being imported as a personal favor for a priest, the devices from Netline Communications Technologies Ltd., a Tel Aviv-based company, are now being used by the four Roman Catholic Churches in this northern city.

The Rev. Juan Jose Martinez, a spokesperson for the archdiocese, highlighted the fact that there are still many people who do not grasp the concept that attending Mass means partaking in a sacred moment with God. Regrettably, the utilization of these small devices became an inevitable choice.

Each unit was purchased for approximately $2,000, and they possess the ability to be remotely activated 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 may receive a notification on their devices stating that there is “no service” or that the “signal is not available.”

Wedding bells

Monterrey’s Sacred Heart church, a baroque temple favored by Mexico’s elite for weddings, had their blockers obtained by church officials two years ago.

The parish clerk, Bulmaro Carranza, noted that at weddings, cell phones would ring every five minutes without fail. This created a troublesome situation, as there were occasions when even the groom would overlook turning off his cell phone.

Unnoticed for an extended period, the devices only came to attention when reporters, who were present at the weddings, started registering complaints regarding the persistent failure of their cell phones.

Carranza stated that in light of the signal blocker becoming known to the public, priests from different regions in Mexico have been phoning him to learn how to acquire them.

At Sacred Heart, a device positioned at the entrance of the church and another near the altar are activated just before each Mass. Nonetheless, the priests consistently urge parishioners to silence their phones before the services commence, with the expectation that proper cell phone etiquette will eventually be embraced.

Martinez noted that The Rosario, San Juan Bosco, and Our Lady Queen of the Angels, as well as other Monterrey churches with the devices, attract wealthier parishioners.

Martinez pointed out that while the cell phone is indispensable for many, individuals should still uphold good manners and demonstrate respect for sacred places.

Margarita Escobedo, a practicing Catholic who diligently attends church services at least twice a week and actively contributes to the San Genaro church as a volunteer, openly embraces the idea of introducing jammers in her parish. Recognizing the increasing nuisance caused by cell phones, she believes that implementing jammers would help restore the sanctity and focus during religious gatherings.

It was mentioned by Escobedo that those who bring cell phones to church are not fully devoted to God. He highlighted the disturbance caused by unexpected noises such as birds chirping or techno music during prayer.

The AIIMS entrance exam has sparked a great deal of commotion, catching many off guard. However, the city university has implemented precautionary measures to avoid such incidents. While certain universities have installed jammers at entrances, others have opted for metal detectors or security guards. Nonetheless, 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 cell phone jammer.

The installation of jammers at the exam hall of Punjab College of Technical Education (PCTE) was carried out by Ms. Kang, the college’s director, two years ago. This decision was made when approximately 900 students were undergoing their exams. Ms. Kang pointed out that the implementation of a disruptor could effectively resolve the issues faced by all individuals by disabling their cell range.

The director of Guru Nanak Institute of Management and Technology (GNIMT), HS Singha, stated that the implementation of two jammers on the campus three years ago has successfully deterred cheating. Furthermore, stringent physical verifications are conducted to ensure students do not have phones in their possession wifi jammer.

MS Saini, the principal of Guru Nanak Dev Engineering College (GNDEC), voiced concerns about students resorting to unethical means to achieve better academic results. He emphasized the challenges posed by the students’ increased capabilities, making physical verification nearly impossible and necessitating the installation of 11 jammers on campus. Furthermore, the college has implemented three metal detectors and enhanced security measures at the entrance gates.

The head of Ludhiana College of Engineering and Technology, Pawan Kumar Gupta, stated that the institution had installed five jammers and two metal detectors on the campus approximately three years ago. He suggested that if other educational institutions adopted similar measures, the likelihood of cheating through technological means would be greatly diminished signal jammer.

Can mobile jammers in colleges stop cyber crime?

The prospect of prohibiting mobile phones on campus has caused a sense of unease among students at universities across the city. The Maharashtra government’s higher and technical education department is contemplating this ban as a preventive measure against cybercrime in universities.

However, students were disenchanted by the perceived violation of their liberties. Lala Atole, a student at ILS Law School, argues that the proposed ban makes no sense 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?”

A student from Garware College, Vedang Bhagwat, brought up a question. Despite students expressing their discontent 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.

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, highlighted that disruptors are not a suitable solution, given the abundance of out-of-town students in Pune and the necessity for their guardians to contact them.

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.

A deadline in May looms for the oilfield company to contest a $126,000 fine imposed by the Federal Communications Commission. This fine was assessed against the company for its disruption of cellphone calls.

Taylor Oilfield Manufacturing Inc. of Broussard was accused of utilizing four cellular phone jammers to restrict cellphone use by employees, leading to the FCC adopting a notice of apparent liability on April 9.

The FCC was informed by company officials that the cell jammers, intended to disrupt cellphone signals, were utilized to prevent employees from using their cellphones while at work.

Taylor has been allotted 30 days starting from April 9 to either remit the penalty or present a written argument to the FCC as to why the fine should be annulled or lessened.

Taylor officials chose not to answer phone calls asking for a response.

The case was instigated following a tip received by the FCC, prompting them to send an agent to the company site in Broussard in May 2012. As stated in the FCC notice, company officials confirmed the usage of four cell jammers and the possession of a fifth cell jammer, which was not operational at the time.

Cell jammers are not allowed to be used within the United States, and the FCC has imposed a ban on companies importing these devices from outside the country. The FCC stated that the Broussard company admitted to acquiring its cell jammer from overseas suppliers.

In its notice to the company, the FCC emphasized the tangible danger to public safety posed by the illegal use of signal blockers. This hazard includes the potential blocking of authorized communications, such as emergency calls to 911 and law enforcement communications. Moreover, the use of cell jammers can have adverse effects on global positioning system signals.

According to FCC records, Taylor’s representatives reported that the company endeavored to prohibit employee cellphone use following a near accident that was partly associated with an employee using a cellphone.

The removal of all cellphone jammers from prisons has been carried out quietly by Corrections.

The introduction of technology in 2008-09 to prevent inmates from accessing smuggled mobile phones has resulted in a total cost of over $17 million.

As of June, jammers have been rendered obsolete after being found to interfere with the effectiveness of the newly introduced safety systems for prison guards.

Minister of Corrections, Phil Goff, highlighted the introduction of cellphone blocking in New Zealand prisons as a pivotal development that will effectively prevent inmates from carrying out additional offenses while incarcerated.

The Official Information Act was utilized to gather recent data on the amount of cellphones taken from the 18 prisons overseen by Corrections during the previous three years.

From January 2020 to November of this year, the Corrections staff discovered 626 cellphones and more than 750 cellphone-related items, like batteries, chargers, and SIM cards.

Neil Beales, the Corrections chief custodial officer, clarified that the absence of cellphone jammer in the prison since June was the cause behind inmates smuggling cellphones.

As per his statement, it was found that the jammers were interfering with the functionality of recently implemented safety systems, specifically affecting alarms utilized for the safety of corrections officers.

Improvements in mobile technology have caused jammers to become increasingly outdated.

According to Beales, the mentioned tool was just one of several tools utilized to prevent the use of cellphones in prisons. He highlighted that there are still numerous other more effective tools that continue to be implemented.

Cellsense devices excel in the detection of metals commonly found in cellphones, offering a comprehensive solution. Alongside their screening and x-ray capabilities, these devices utilize specially trained dogs to enhance their metal detection capabilities.

Beale highlighted that certain individuals in prison resort to extreme and elaborate measures to introduce contraband into prisons, and we are consistently working to anticipate the new methods used for smuggling contraband into our correctional institutions.

As per the spokesperson, Corrections has been exploring new and emerging technology to complement their current systems. They have initiated the use of full body imaging technology at several sites to detect contraband concealed on or within individuals.

It was revealed in 2018 that Corrections had implemented cellphone jamming technology, resulting in a communications blackout near Rimutaka Prison and the subsequent inability to monitor residents of a child sex offender unit outside the prison grounds.

Inmates may exploit cellphones to manipulate individuals outside the prison walls and to organize illegal activities like drug transactions. Nine prison staff members at Rimutaka were suspended in May for alleged misconduct, including the smuggling of cellphones into the facility.

It is unsurprising that Corrections has opted to abandon the use of jammers, as Roger Brooking, a drug and alcohol counsellor and criminologist, has been vocal about his reservations regarding the expenditure on this technology.

It was his assertion that they are ineffective and have never been successful.

From what I have been told by prisoners, they have found certain locations within the prison where the signal blockers is ineffective. This has allowed inmates to continue using cellphones for purposes such as conducting illegal deals or communicating with their families.
