The use of devices originally designed to prevent eavesdropping and thwart phone-triggered bombings is on the rise in order to block incoming cell phone calls.

 

The initial observation was made by the reporters. As they were occupied with the coverage of high-profile weddings, they encountered difficulties in reaching their editors due to the lack of cell phone reception at Sacred Heart. Seeking an explanation, they approached the priest who revealed that Israeli counterintelligence was responsible for the interference.

 

Among the paintings of the Madonna and statues of saints in four churches in Monterrey, inconspicuous cell phone blocker, produced in Israel and resembling small books, have been strategically positioned.

 

The harsh polychromatic sound of ringing cell phones is now being prevented in a variety of locations, including religious sanctuaries, India's parliament, Tokyo theaters, and commuter trains, by tools that were originally designed to aid security forces in preventing eavesdropping and stopping phone-triggered bombings.

 

Following the disregard of requests from politicians to silence their cell phones, signal blocker were installed in the Indian parliament to prevent further disruptions during legislative sessions.

 

The adoption of blockers in Italian universities came about when it was discovered that students, who were adept at using cell phones, were resorting to cheating during exams by exchanging text messages or capturing pictures of the test content.

 

In this northern city, the four Roman Catholic Churches have started utilizing devices from Netline Communications Technologies Ltd., a company based in Tel Aviv. These devices were brought in by an insurance salesman as a personal favor for a priest.

 

According to the Rev. Juan Jose Martinez, a representative of the archdiocese, there remains a considerable number of individuals who lack the understanding that being present at Mass involves sharing a significant moment with God. Unfortunately, the use of these small gadgets became the only available option.

 

Acquired at a price of around $2,000 per unit, these devices can be activated using a remote control and emit radio frequencies at a low level. Their primary function is to interfere with cell phone signals within a 100-foot range.

 

When using their cell phones, users may receive a message indicating that there is "no service" or that the "signal is not available."

 

Wedding bells

 

Two years ago, church officials in Monterrey acquired blockers for the Sacred Heart church, a baroque temple often chosen by Mexico's elite for weddings.

 

According to Bulmaro Carranza, a parish clerk, cell phones would constantly ring every five minutes during weddings. This became a major concern, especially when the groom would occasionally forget to switch off his cell phone.

 

Unbeknownst for months, the devices went undetected until reporters, who were assigned to cover the weddings, started voicing their grievances about the perpetual malfunctioning of their cell phones.

 

According to Carranza, following the revelation of the jammers, priests from all over Mexico have been contacting him to inquire about obtaining them.

 

Before the commencement of every Mass at Sacred Heart, a device located at the church entrance and another adjacent to the altar are activated. However, the clergy consistently remind parishioners to power off their mobile phones prior to the start of the services, in the hope that a culture of good cell phone manners will eventually prevail.

 

The Rosario, San Juan Bosco, and Our Lady Queen of the Angels, along with other Monterrey churches with the devices, are visited by wealthier parishioners, according to Martinez.

 

According to Martinez, the cell phone may be essential for many individuals, however, this should not be an excuse for neglecting proper etiquette and failing to respect sacred sites.

 

Margarita Escobedo, a committed Catholic who faithfully attends church twice a week and selflessly dedicates her time to volunteering at the San Genaro church, expresses her support for the implementation of jammers in her parish. She acknowledges the growing annoyance caused by cell phones and believes that their interference can be effectively addressed through the use of such technology.

 

According to Escobedo, people who bring cell phones to church are showing a lack of dedication to God. He pointed out that hearing sounds like birds chirping or techno music can be extremely distracting while trying to pray.

Congressman David Kustoff (TN-08) has reintroduced the Cellphone Jamming Reform Act of 2022, which targets the problem of contraband cell phone use in federal and state prison facilities. This bill would authorize state and federal prisons to utilize cell phone jamming systems in order to protect inmates, guards, and the public.

 

The companion bill was introduced in the U.S. Senate by Senators Tom Cotton (R-AR) and Lindsey Graham (R-SC), with support from Representatives William Timmons (SC-04), Tom Rice (SC-07), Ralph Norman (SC-05), and Jeff Duncan (SC-03) as co-sponsors.

 

The statement made by Congressman Kustoff emphasized that inmates in correctional facilities nationwide are utilizing contraband cell phones to conduct illegal activities, such as running drug operations, facilitating sex trafficking, and coordinating escapes.Congress must take decisive action to address the problem of contraband cell phones, as they enable dangerous criminals to perpetuate illegal activities from within prison walls, posing a threat to public safety.It brings me great pleasure to team up with Senators Cotton and Graham in reintroducing this essential bill that will safeguard our communities in West Tennessee and the United States.

 

Inmates have employed illicit cell phones to coordinate illegal activities beyond the confines of correctional facilities, such as orchestrating attacks on adversaries, engaging in sex trafficking, running drug enterprises, and conducting business deals.Despite the potential of cellphone signal jamming devices to stop this, the Federal Communications Act prohibits facilities from implementing this technology. The proposed bill seeks to remedy this situation, ensuring that criminals can serve their sentences without posing a threat to public safety.

 

The Correctional Leaders Association, the Council of Prison Locals, the American Correctional Association, the National Sheriff's Association, and the Major County Sheriffs of America stand behind this legislation.

 

In both federal and state prison facilities, the prevalence of contraband cell phones is widespread. Inmates have exploited these unauthorized devices to engage in a range of illegal activities, such as orchestrating targeted attacks on individuals beyond prison confines, operating illicit drug networks, conducting unlawful business transactions, facilitating sex trafficking, and organizing escapes that pose risks to correctional staff, fellow inmates, and members of the public.

 

The South Carolina Prison Incident was ignited by the presence of cell phones and contraband. A brawl ensued inside the Lee Correctional Institution near Bishopville, South Carolina, as rival gangs clashed over territorial control. The use of cell phones to trade contraband further fueled the intensity of the confrontation. Tragically, this violent incident resulted in the deaths of seven inmates and left 20 others injured.

 

In 2013, Lt. Osvaldo Albarati, a correctional officer at the Bureau of Prisons, was killed for disrupting an illicit contraband cell phone business. The inmate responsible for his assassination used a contraband cell phone to contact the gunman, as detailed in the indictment.

 

In 2018, a report exposed how an FCI Fort Dix inmate in New Jersey orchestrated a murder and assault through a smuggled phone within the prison. Another inmate at the same facility faced charges for possessing and disseminating child pornography using a contraband phone. Additionally, six other inmates confessed to their involvement in criminal activities.

 

Contraband cell phones not only enable violent criminals to carry out their illicit activities but also have wider implications. The Wall Street Journal reported that Martin Shkreli, the disgraced pharmaceutical executive sentenced to seven years for securities fraud, managed to make decisions at Phoenixus AG by using a contraband cell phone.

The ability to communicate with others at all times is truly advantageous. Nevertheless, the excessive use of cell phones in restaurants, movie theaters, concerts, shopping centers, and churches has led to disruptions, as some individuals do not know when to cease their conversations.Is there anyone who hasn't felt annoyed by being privy to a conversation about a very personal issue, where the speaker discloses intimate details to their friend and the people nearby?

 

Despite most people merely grumbling and moving forward, there are those who resort to extreme measures for retribution. Cell phones, essentially functioning as portable two-way radios, are susceptible to signal disruption or jamming, much like any other radio device.

 

The function of jamming devices is to overpower cell phones by transmitting a signal on the same frequency and with enough power to cause the two signals to collide and negate each other. Cell phones are equipped to enhance their power in the presence of low-level interference, therefore the signal jammer must be capable of identifying and matching the power increment from the phone.

 

Cell phones are designed as full-duplex devices, utilizing two distinct frequencies for talking and listening simultaneously. Certain jammers disrupt one of the frequencies used by cell phones, causing both frequencies to be blocked. This results in the phone being misled into thinking there is no service available, as it can only receive one frequency.

 

Basic devices are capable of blocking a single group of frequencies, whereas advanced wifi jammer can simultaneously block multiple types of networks. This prevents dual-mode or tri-mode phones from automatically switching between different network types in search of an available signal. Certain high-end devices have the ability to block all frequencies simultaneously, while others can be adjusted to target specific frequencies.

 

To disrupt a cell phone signal, one only needs a device that can broadcast on the right frequencies. Despite differences in signal processing among various cellular systems, all cell phone networks utilize radio signals that are susceptible to interruption.Europe and Asia employ GSM in digital cellular and PCS-based systems, utilizing the 900-MHz and 1800-MHz bands, while in the United States it operates within the 1900-MHz (sometimes referred to as 1.9-GHz) band.Jammers have the ability to transmit signals on various frequencies, enabling them to effectively disrupt AMPS, CDMA, TDMA, GSM, PCS, DCS, iDEN, and Nextel systems. Regardless of whether it is an old-fashioned analog cell phone or a modern digital device, both types are equally prone to being affected by jamming.

 

The actual range of the gps jammer depends on its power and the local environment, which may include hills or walls of a building that block the jamming signal. Low-powered jammers block calls in a range of about 30 feet (9 m). Higher-powered units create a cell-free zone as large as a football field. Units used by law enforcement can shut down service up to 1 mile (1.6 km) from the device.

 

I'll give you a serious answer since many others won't. I know from experience that, yes, your neighbor COULD have such a device. They're rather inexpensive. $150 can get someone a cell phone jammer conveniently delivered to their door.

 

Is it likely though? Anything is possible. You never really know who your neighbors are. I move around a lot & after all the awful neighbors I have had, I put nothing past anyone.

 

FCC probably won't take your claim seriously without proof. Just repeat the performance a few times & record the results. However, if the guy has a gsm jammer it would probably be best not to talk about your test out loud.

 

Reason being, when someone has a jammer, they usually also have a listening device. No, I am not joking. Every person in this would be paranoid if they knew the number of people who buy listening devices so they can spy on their neighbors for shits & giggles....or worse more malicious reasons.They're easy to acquire & work wonderfully. Don't talk about your plan to test him so you can record it. If he has a jammer, chances are that he's the type to have such a device to listen to you in your home.

The utilization of cellphone jammers within the country's penitentiaries falls short in preventing incarcerated criminals from transmitting messages to individuals outside the confines of the prison.

This is the view of senior prison officials who tell the Sunday Express that even though the jammers (which they say are operational) are used to block signals from cellphones within the prisons, other interception technologies are needed for the system to be effective.

The utilization of cellphone jammers is prevalent, however, their optimal efficiency is achieved when integrated with complementary technologies like Wi-Fi jammers. This practice has been successfully implemented in other jurisdictions, yet its proper implementation is yet to be realized here.

Within the prison, there will be individuals in possession of cellphones and tablets, but they will not have the capability to place phone calls. Nevertheless, they can still communicate by utilizing the device's data or, if they have access to a hot-spot device or a Wi-Fi box, they can make calls through social media platforms like WhatsApp, Facebook, and Instagram. Hence, the challenge of maintaining communication with the outside world persists. Communication remains ongoing.

“In other jurisdictions, you will see the cellphone jammers being used with other interception devices to determine the frequencies used by these devices, and then target those specific frequencies. If this is not done, then it’s almost like spinning top in mud,” a senior source in the Prison Service explained yesterday.

Furthermore, as per the Sunday Express, the signal blockers employed and operated within the confines of the Prison Service are under the management of a third party.

In response to recent inquiries, Acting Prisons Commissioner Deopersad Ramoutar chose not to address the specific questions regarding the functionality of the cellphone jammers. He deemed this information as privileged and clarified that it does not fall under the jurisdiction of the Prison Service.

According to additional senior officials, as reported by the Sunday Express, they are still functioning.

Among the illicit items confiscated at the Maximum Security Prison in Arouca, officials uncovered a Wi-Fi box.

As part of the search operation, law enforcement conducted meticulous searches, resulting in the discovery and seizure of a bag in a particular cell situated near the toilet area. The bag contained 53 grammes of marijuana, as well as cellphones and the Wi-Fi box.

Within a separate enclosure, authorities uncovered and apprehended a satchel holding 104 packs of cigarettes and marijuana, amounting to a total weight of 241 grams.

Two inmates asserted ownership of the confiscated items.

Concerns were voiced by prison officers on Friday regarding the presence of drones flying over prisons. A senior officer stressed the urgency of addressing this issue, referring to it as a potential "ticking time bomb."

A single drone that manages to evade our detection could have severe consequences. It could potentially transport dangerous weapons like knives or guns, creating a highly precarious situation. Although we have successfully confiscated prohibited items like cigarettes, marijuana, phones, and chargers, the failure to intercept even one drone poses a significant risk to the prison and the entire country.

The officers obtained information that pointed them towards the cells within the B Division of the prison.

According to Ramoutar, the Prison Service has recognized a surge in the prevalence of drones being employed around correctional institutions, particularly over the past year, leading them to take necessary actions.

With the support of multiple divisions within the National Security portfolio, he mentioned that the majority of the items that were dropped over prison walls were intercepted before they could be accessed by the inmates.

With the imminent arrival of the exam, the utilization of 5G signal jammers has been extensively promoted and put into practice. These mobile phone jammer are actively employed and can be spotted in exam rooms across major schools. The rationale behind the escalating installation of this equipment in educational institutions is worth exploring.

Mariam Aly, an assistant professor at Columbia University, has employed a range of strategies in her quest to prevent her students from cheating. In her cognitive neuroscience class, she grants her students a week to finalize an open-book exam. Additionally, as part of this exam, the class's nearly 180 students must adhere to an honor code by signing it.

 

Nonetheless, the act of cheating persists. When it comes to handling student misconduct, she claims it to be the most challenging part of her profession. Aly acknowledges, "It creates an awkward and painful situation for all parties involved." She further states, "It is exceedingly difficult to place blame solely on them. One cannot help but feel disappointed and frustrated."

 

She acknowledges that her students are facing extraordinary levels of stress and uncertainty, and she can empathize with them. Having never attended school during a pandemic, she understands the unique challenges they are going through.

 

The level of popularity attained by something is contingent upon the demand it generates. This phenomenon can be attributed to the growing prevalence of cheating, which has become more and more widespread in recent years, accompanied by the frequent appearance of alarming cheating methods.

 

To address the problem in an effective manner, a specialized form of shielding equipment is utilized within the examination room to counteract cheating facilitated by electronic signals. The presence of this equipment proves immensely beneficial for a wide range of examinations, leading to an increasing number of individuals choosing to employ it as a means of preventing cheating.

 

With its advanced technology, this type of exam signal blocker can efficiently disrupt the communication signals of 5G mobile phones, as well as effectively block 2.4G and 5.8G WIFI signals. Consequently, individuals using mobile phones or specific electronic devices will encounter signal transmission and reception issues within the designated range of this shielding device.

 

Regardless of the product, only this guarantee can provide fairness to test takers who struggle with their exams, and this exam signal jammer operates in complete silence and without any noise. This shielding technique poses no harm to the human body, allowing candidates to take the exam with peace of mind.

We extend our help to parents and guardians who seek to ensure additional online safety for children using internet-enabled devices. Our service efficiently blocks inappropriate digital content and enables tracking of the child's online activities.

 

Dad Uses Signal Jammer to Stop His Kids from Going Online

 

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

 

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

 

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

 

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

 

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

 

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

 

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

 

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

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

 

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

 

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

 

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

 

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

 

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

A cell phone jammer is an electronic device that blocks signal transmission between a cell phone and a cell tower. By using the same frequencies as cell phones, signal jammers can cause strong interference with communications between callers and receivers. Can effectively block signal transmission from networks such as UMTS, 3G, CDMA, GSM and PHS.

For any jammer circuit, there must be three important sub-circuits:

RF amplifier

Voltage Controlled Oscillator

Tuning circuit

These 3 circuits combine to form an efficient cell phone jammer circuit.

 

Cell phone signal jammer working

 

Within the RF amplifier circuit, there is transistor Q1, as well as capacitors C4 and C5, and resistor R1. This particular circuit serves the purpose of amplifying the signal that is generated by the tuned circuit. Once amplified, the signal is then sent to the antenna through capacitor C6. By doing so, capacitor C6 prevents the transmission of any DC current, allowing only the AC component of the signal to pass through.

 

The turning on of transistor Q1 triggers the activation of the tuned circuit located at the collector. Comprised of capacitor C1 and inductor L1, this circuit operates as a zero resistance oscillator, producing exceptionally high frequencies with minimal damping.

As time progresses, the magnetic charge passing through the inductor decreases, resulting in the capacitor being charged in the opposite or reverse polarity. This sequence is repeated, and eventually, the inductor charges the capacitor until it reaches a neutral state.

 

The cessation of oscillation occurs when internal resistance is established, signifying the continuation of this process. Before reaching the collector terminal, the RF amplifier feed is directed through capacitor C5, followed by C6. Capacitors C2 and C3 generate random pulses (noise) at the frequency generated by the tuned circuit.

 

The frequencies generated by tuned circuits are amplified using RF amplifiers. These amplifiers combine and amplify the frequency produced by the tuned circuit with the noise signal generated by capacitors C2 and C3 before transmitting it.

The fact that parents often consider purchasing cell phones for their children and teenagers is quite understandable. The primary reason behind this is to maintain a constant connection with their children. With a phone at hand, children have the convenience of reaching out to their parents whenever required, whether it is to coordinate a pick-up from school or to seek immediate assistance during an emergency.

 

It is crucial to take into consideration certain matters that accompany the purchase of a cell phone for your child. These matters hold considerable importance and should be acknowledged by many parents, as they encompass not only the risks associated with cell phone usage but also behavioral issues. Before providing your child with a mobile phone, it is essential to closely monitor their behavior.

 

Addiction is problematic

 

The technological advancements found in cell phones have a strong appeal to children and teenagers, making them susceptible to addiction. Engrossed in texting, browsing social media, and constantly communicating with friends, they find it difficult to detach from their phones. Regrettably, the prevalence of cell phone addiction is escalating, adding to the gravity of the situation.

The inclination towards excessive cell phone usage can result in a lack of concentration on academic pursuits and other essential matters. This phenomenon arises as students persistently utilize their phones to browse social media platforms such as Facebook or Twitter, engaging in chats instead of dedicating time to studying and fulfilling course-related obligations.

 

Misconduct

 

The worst part about cell phones for kids is that many of them can engage in extremely inappropriate and potentially dangerous behaviors. Questions about bullying and how easily it spreads online have persisted for years. With mobile devices, people can easily be bullied. Children and teenagers can send each other angry messages non-stop. They may even make it harder for other children to enjoy their lives, or they may even ruin their own lives.

 

Additionally, children may send inappropriate images and text to others. They may send or receive dirty and possibly sexually explicit messages. They may not know how inappropriate these things are.

 

The pictures children take of themselves can also be quite disturbing. Children may take photos of themselves without clothes and send them to others. This can be harmful because children expose their bodies to others who want to see them. This is a serious threat and not many children realize what they may sometimes encounter.

How teens and parents can deal with screen time and device distractions

 

54% of U.S. teens say they spend too much time on their phones, and two-thirds of parents are concerned about their children’s screen time.

 

Parents are also concerned about the impact of screen time on their children, a separate survey showed. About two-thirds of parents said they were concerned about their children spending too much time in front of screens, and 57% reported setting screen time limits for their children in some way.

 

Meanwhile, some parents of teens admit they too struggle with the lure of screens: 36% say they themselves spend too much time on their phones. 51% of teens said they often or sometimes find their phones distracting them when trying to talk to their parents or caregivers.

 

With the rapid development of mobile communication technology and the popularization of smart devices such as smartphones and tablets, students’ use of smartphones has reached the level of one for every student. In the past two years, due to the epidemic, students’ use of smartphones has also increased. Come more and more. It is impossible to learn school class knowledge through online classes on mobile phones. Although the school has repeatedly banned students from bringing mobile phones to campus, some students still bring mobile phones to campus. Schools face many challenges in managing smartphones:

Students use mobile phones to play games and chat online, and even adolescent children browse unhealthy content online, which seriously affects physical and mental health;

 

Students do not sleep at night after school, cannot concentrate in class the next day, and easily fall asleep in class, etc., resulting in serious deterioration in academic performance;

Use mobile phones and other devices to cheat in exams, etc.

 

Based on the current situation, what we can do is:

Parents should increase the time for interaction and communication with their children, pay more attention to their children's life and study, and take their children for outdoor sports. This will reduce the time children spend playing at home when they have nothing to do, and will also help cultivate parent-child relationships.

 

Guide children to play some educational games or learnin

 

g software to make education interesting and emphasize that the Internet is a learning tool, not a toy.

 

Control the time children play games: Use a cell phone jammer to properly control the Wi-Fi network signal of the mobile phone so that students’ mobile phones cannot play online games within a certain period of time. Reduce conflicts between children and parents during the communication process.

 

Jamming mobile phones can be installed in school classrooms. Mobile phone wifi jammer can be turned on during class to block mobile phone signals in the classroom, and mobile phone signals can be restored during breaks.

 

The dormitory can be equipped with a mobile phone signal jammer. After turning off the lights at night, turn on the mobile phone signal jammer to restore the mobile phone signal late at night. Use cell phone signal jammer wisely.

A cellphone-free zone surrounding their cars is a coveted concept for numerous drivers. However, the daily actions of a Florida man, who reportedly achieved this, did not necessarily contribute to a safer highway.

 

According to the U.S. Federal Communications Commission, Jason R. Humphreys, a resident of Seffner, Florida, was discovered to have operated a cellphone jammer in his Toyota Highlander sport-utility vehicle for a duration of two years. This illicit behavior occurred during his daily commute, but he was eventually located and apprehended by both the FCC and the local sheriff.

 

Humphreys stated to the FCC that he utilized the vehicle cell phone jammer to prevent individuals from engaging in cellphone conversations while operating a vehicle. It is worth mentioning that in Florida, talking on a cellphone while driving is permissible, even without a hands-free kit, although texting while driving is prohibited.

 

Not only do jammers prevent consumers from making emergency calls, but they can disrupt critical communications by safety agencies, the FCC said. Hillsborough County sheriff's deputies confirmed that firsthand when they pulled Humphreys over. They said their two-way portable radios lost contact with the dispatcher as they got close to the SUV.

 

A stretch of Interstate 4, spanning from Seffner to downtown Tampa, approximately 12 miles apart, caught the attention of Metro PCS, the regional mobile operator now owned by T-Mobile USA. On April 29, 2013, Metro PCS notified the FCC about interference issues affecting their cell towers along this route during the morning and evening commutes. Prompted by this report, the FCC conducted an investigation utilizing direction-finding techniques, ultimately identifying strong wideband emissions emanating from a blue Highlander.

 

After halting the SUV, FCC agents and sheriff's deputies engaged in a discussion with Humphreys and proceeded to meticulously examine the vehicle. The search led to the discovery of the signal blocker, cleverly concealed behind a seat cover on the backseat, as confirmed by the FCC. Humphreys allegedly confessed to utilizing the jammer during his daily commute for a period of 16 to 24 months. Subsequent testing revealed that the device possessed the capability to interfere with cell signals across three distinct bands.

 

The allegations against Humphreys involve the unauthorized operation of a jammer, the use of an illegal device, and the deliberate interference caused.
