jammer

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

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

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


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

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

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

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


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


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


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


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


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

The Cellphone Jamming Reform Act of 2022 has been reintroduced by Congressman David Kustoff (TN-08) to address the issue of contraband cell phone use in federal and state prison facilities. This legislation would empower state and federal prisons to utilize cell phone jamming systems in order to safeguard inmates, guards, and the broader community.

Senators Tom Cotton (R-AR) and Lindsey Graham (R-SC) brought forth the companion bill in the U.S. Senate. In addition, Representatives William Timmons (SC-04), Tom Rice (SC-07), Ralph Norman (SC-05), and Jeff Duncan (SC-03) have co-sponsored this legislation.

According to Congressman Kustoff, inmates in correctional facilities nationwide are employing contraband cell phones to engage in illegal activities, such as overseeing drug operations, supporting sex trafficking, and planning escapes.Congress is urged to address the pressing issue of contraband cell phones, ensuring the safety of the public from criminals who persist in engaging in illegal activities while in prison.It is with great satisfaction that I join Senators Cotton and Graham in reintroducing this significant bill, which is designed to enhance the safety of our communities in West Tennessee and throughout the United States.

Convicts have employed contraband cell phones to oversee illicit operations outside prison premises, which encompass targeting rivals, facilitating sex trafficking, running drug schemes, and negotiating business agreements.The use of cellphone signal jamming devices can effectively halt this activity, yet the Federal Communications Act currently prohibits facilities from employing such technology. The proposed bill seeks to rectify this situation, ensuring that criminals can be incarcerated without jeopardizing public safety.

This legislation has the backing of 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.

Within both federal and state prison facilities, the utilization of contraband cell phones is widespread. Inmates have exploited these unauthorized devices to carry out unlawful activities, including commissioning assaults on individuals outside prison walls, managing illicit drug operations, conducting illegal business transactions, facilitating sex trafficking, and organizing escapes that jeopardize the safety of correctional employees, fellow inmates, and the public.

The South Carolina Prison Incident was instigated by the combination of cell phones and contraband. A territorial dispute among gangs within the Lee Correctional Institution near Bishopville, South Carolina escalated into a chaotic brawl, with cell phones being utilized to facilitate the illegal exchange of contraband. Regrettably, this violent confrontation claimed the lives of seven inmates and caused injuries to 20 others.

The tragic death of Lt. Osvaldo Albarati occurred in 2013 at the hands of an inmate involved in an illicit contraband cell phone scheme. The inmate utilized a contraband cell phone to communicate with the hired shooter, leading to the fatal attack, as described in the official report.

A report from 2018 detailed how an inmate at FCI Fort Dix in New Jersey used a smuggled phone to plan a murder and assault while incarcerated. Another prisoner at the same facility faced charges for possessing and distributing child pornography via a contraband phone. Furthermore, six other inmates confessed to their involvement in various crimes.

Contraband cell phones serve a purpose beyond facilitating the unlawful activities of violent criminals. The Wall Street Journal recently disclosed that Martin Shkreli, the disgraced pharmaceutical executive who received a seven-year sentence for securities fraud, continued to exert control over decision-making processes at Phoenixus AG through the use of a contraband cell phone.

It is wonderful to have the ability to contact anyone at any given moment. Regrettably, establishments such as restaurants, cinemas, music venues, shopping centers, and places of worship are negatively impacted by the prevalence of cell phones, as some users do not recognize the appropriate times to end their conversations.Has anyone not experienced the frustration of overhearing a conversation about a deeply personal matter, where the speaker divulges intimate details to their friend and everyone else nearby?

Many individuals tend to express their dissatisfaction and continue with their lives, but there are those who take drastic measures to seek revenge. Cell phones, in essence, function as portable two-way radios, susceptible to signal disruption or jamming, just like any other radio device.

Jamming devices are capable of overpowering cell phones by emitting a signal on the identical frequency and with sufficient power to cause the two signals to collide and nullify each other. In order to counteract low-level interference, cell phones are programmed to amplify their power, thus the signal jammer needs to identify and match the power boost from the phone.

Mobile phones operate as full-duplex devices, utilizing distinct frequencies for talking and listening at the same time. Certain gps jammer disrupt one frequency used by cell phones, resulting in the blocking of both frequencies. This causes the phone to believe there is no service available as it can only pick up one frequency.

Less intricate devices have the capability to obstruct a single set of frequencies, whereas advanced wifi jammer possess the ability to obstruct multiple network types simultaneously in order to prevent dual-mode or tri-mode phones from seamlessly switching between different networks to locate an available signal. Certain high-end devices have the capability to block all frequencies simultaneously, while others can be adjusted to target specific frequencies.

In order to block a cell phone signal, a device capable of transmitting on the appropriate frequencies is required. Despite variations in how different cellular systems handle signals, all mobile networks rely on radio signals that are susceptible to disruption.In Europe and Asia, GSM is employed in digital cellular and PCS-based systems, operating within 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 possess the capability to transmit signals across various frequencies, thereby rendering them efficient against a wide range of systems including AMPS, CDMA, TDMA, GSM, PCS, DCS, iDEN, and Nextel. Both outdated analog cell phones and modern digital devices are equally vulnerable to interference caused by jamming.

The actual range of the gsm 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 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.

Drones have left an indelible mark on the Ukraine war, unlike any other conflict, as they range from small quadcopters equipped with cameras and grenades hovering over front-line trenches to aerial bombs carrying warheads weighing several dozen kilograms (pounds) into Kyiv and Moscow.

Over the past few months, Kyiv and other major cities have faced a series of attacks from Russian forces, who have deployed Iranian-manufactured Shahed "kamikaze" drones. In response, Ukraine has also carried out unmanned assaults in Crimea and the Russian border region of Belgorod.

On Tuesday, the Russian government went as far as accusing Ukraine of launching an attack on Moscow using these very devices.

The current image starkly contrasts with the excessive excitement that once surrounded the Turkish-manufactured Bayraktar TB2 drones during the initial stages of the conflict.

The aircraft garnered significant attention and received accolades in music for their contribution in dismantling Moscow's armored columns and the flagship of the Black Sea fleet, the Moskva.

However, the ongoing conflict has rendered these models, referred to as MALE (Medium Altitude, Long Endurance), obsolete.

According to an anonymous source from the European defense industry, the front line has now reached a state of stability and has become impervious due to the deployment of Russian defense systems to counter airborne attacks, as reported by AFP.

The drone war has now transformed into a battle of statistics.

According to a senior French military source, the majority of suicide drones are intercepted by air defenses, which are strategically employed to compel the defenders to engage their missiles and deplete their reserves.

“You also create terror and uncertainty at all times. Over the long term, that has value,” the source added.

It is crucial for Russia to degrade enemy air defense systems at a low cost, as highlighted by analysts Jack Watling and Nick Reynolds from the British defense think-tank RUSI in a recent report. Russia's production of long-range missiles is currently limited to approximately 40 per month.

According to reports, the air force of Moscow deploys a significant number of aircraft to expand the range of potential threats and to detect vulnerabilities in the Ukrainian air defense system. This strategy aims to identify areas where conventional missiles could penetrate.

According to the European industrial source, Kyiv utilizes commercially available Chinese propeller-powered drones or old Soviet jet-powered reconnaissance drones to carry out attacks deep within Russian territory.

– Front lines –

Most drones in use are compact models deployed for reconnaissance and offensive operations on the battlefield.

Ukrainian forces have shared numerous videos on various social media platforms depicting altered commercially accessible drones releasing explosives on Russian troops' locations.

It is common to find between 25 and 50 UAVs from each side on a 10-kilometre front line, as stated by RUSI's Watling and Reynolds.

Ukrainian Furia and Russian Eleron-3 drones are designed for specific purposes and can cover distances of up to 50 kilometers. In contrast, commercially modified quadcopters, often purchased through crowdfunding, have a limited range of less than 10 kilometers.

The deployment of electronic defenses by both sides has been prompted by the swarms, resulting in a reduction in the cost of countering inexpensive devices that are not worth shooting down with expensive missiles.

According to RUSI, the Russian forces currently utilize around one significant electronic warfare system for every 10 kilometers of frontage. Furthermore, there are additional, more specialized electronic warfare capabilities that are deployed higher up in the chain of command.

The senior French officer expressed that the Russians have intensified their electronic warfare tactics, signifying a significant shift in their approach.

Russian platoons are now outfitted with anti-drone weapons, as stated by RUSI, which include directional jammers and arrays designed to hijack UAVs drone jammer.

Anti-drone “rifles” that emit jamming signals are “the absolute basics of defence, what really works are non-portable jammers deployed close to the front line”, the European industry source said signal jammer.

However, these "large spheres mounted on tripods with generators" are easily identifiable and have a short lifespan, according to their statement.

– High attrition –

The French officer described drone and anti-drone warfare as a modern iteration of combined arms combat.

Similar to the presence of infantry, cavalry, and artillery, we also possess drones, electronic warfare, and connectivity.

The officer emphasized that due to the extensive efforts made to destroy them, the majority of small drones will not remain airborne for more than four to six instances before being intercepted and shot down.

Ukraine has claimed that they are experiencing a significant loss of approximately 10,000 drones every month across their extensive range of devices. However, the accuracy of this figure cannot be confirmed, and it is speculated that this statement may be an attempt to secure additional aid from Western nations.

In the event of breakthroughs and counter-offensives leading to the resurgence of quickly changing front lines, drones will continue to be significant.

Ukraine has the potential to employ drones in eliminating Russian defensive obstacles during its anticipated summer offensive, such as utilizing them to deliver explosives into a minefield, effectively creating a passage, as suggested by Vikram Mittal, a faculty member at the US military institution West Point, in an article for Forbes.

In situations where fast-moving troops become isolated, drones could provide a solution for delivering essential supplies like ammunition to ensure their operations can carry on.

GPS signal jammers come in a variety of designs, each suited for slightly different uses.GPS, Galileo, Chinese, Japanese and Russian satellite navigation systems and their enhancements all use essentially the same technology and the same frequency bands.Even more serious than jammers are civilian GPS spoofers, which have been shown recently.Spoofing is sending fake GPS signals; the receiver locks on to them, and the spoofer takes control of the receiver.Vehicles will also be able to avoid a purely GNSS-based road user pricing system.But there are already low-cost GPS generators with programmable scenarios that can use Google Earth to input trajectories.

The models intended for cars, for instance, only work while the car and thus the GPS signal jammer is powered on.They use them to disrupt tracking systems, thereby stealing vehicles and their valuable content.Jammer: A low-power radio transmitter that can overwhelm GPS reception at a range of tens of meters.It blocks the data channel of any tracking system and disables mobile devices that can be used to call for assistance or track themselves using cell site analysis.Nearby jammers can easily deafen a vehicle's sat navigator because it's hard for them to hear these tiny signals.

Today, it’s almost ridiculously easy to gain access to such a transmitter.Many people produce fake GPS locations to prevent applications from precisely tracking their movements.In a GPS spoofing attack, a terrestrial radio transmitter mimics GPS signals at a greater signal strength than the actual system can muster, effectively replacing real GPS signals with a fake signal.Spoofing GPS is no longer something that requires the resources of a nation-state.One of the reasons that GPS is easy to spoof is that the signal is unencrypted.Since no form of authentication or verification is required for GPS transmissions, just about anyone can use the publicly available specifications and falsify a location.

It might be a bit mystifying to some as to why someone might want to jam a GPS signal.Improve its technology to detect jammers and try to legally ban their sale and use.GPS and other Global Navigation Satellite Systems (GNSS) circle the earth in medium earth orbit, which is around 12,550 miles above the ground – the equivalent of almost five trips from San Francisco to New York.Since those satellite signals are transmitted across such a great distance, they are pretty weak by the time they actually reach your device.This used to be complicated, expensive electronics that only militaries could do.

GPS jammers can also disrupt many communication systems, including the Tetra Airwave system used by emergency services.And you can still be tracked by your mobile phone’s own signals if you don’t take precautions.However, just because you have a GPS signal jammer doesn’t mean you still can’t be tracked.Of course, terrorists fighting on the ground in Afghanistan and other countries also make use of GPS signal jammers, some Russian-made.Not enough to disrupt signals from other cars, but enough to keep you in a cone of gps jamming silence.

This jammer would beat GPS-based road user pricing systems, and jammers ten times more powerful than those on the market today.The first, and most popular model to hit the mainstream market was one that plugs into the cigarette lighter of a car, effectively disrupting the signal for a 15-foot radius.There are a number of types of noise signals it can send; some call for a narrowband Gaussian signal, others for a simple continuous wave.The GPS signal jammer works by sending out its own signal on the same frequency as the GPS unit, a noisy signal that prevents it from receiving or transmitting any useful information.

Fraudsters will allow criminals to hijack and divert the vehicle, while the tracking system shows it's still following its planned route, so no alarms will sound.Now, chances are, any GPS you will have contact with uses the radio frequency set aside for civilian use.The basic purpose of cell phone jammer is to prevent GPS loggers from either receiving satellite signals or sending signals back to their base station.However, there are those with a particular need for privacy, be it to massage their paranoia, keep law enforcement from engaging in warrantless car tracking, take an unauthorized lunch break with a GPS-enabled company car, or a teenager not want their parents to track their GPS phone.

But these two are harder to jam than GPS and don't draw people's attention.Some rare can only be found in certain parts of the world – if you can’t travel to get them, placing your phone there virtually is the next best thing.Spoofing your device’s GPS receiver so it displays another place is also a popular way to obtain access to country-specific features of games and other applications.Some do it to maintain control over their personal data by telling location services that are overtly or covertly tracking users that they’re in Kazakhstan.GPS spoofing technology is virtually free, widely available, and very popular.

Effective measures should be taken to eliminate potential safety hazards and jammer gps buy ensure the safety of gas stations.On the one hand, the customer does not know the safety management regulations of the gas station, and believes that it is unnecessary for the gas station employees to let them use their mobile phones in the gas station, which is prone to rebellious psychology.

One of the more difficult to manage is the prohibition of customers using mobile phone calls in gas stations mobile signal jammer.The exercise of any right is limited and must not prejudice the rights of others or the public interest.The freedom of communication and speech that citizens enjoy in accordance with the Constitution and the law shall not exceed their due scope.As we all know, gas stations dealing with flammable and explosive materials are high-risk industries, and "safety first" is the most basic requirement for gas stations.Common safety measures at gas stations mainly include turning off motorcycles to refuel, gas station employees must wear anti-static clothing to work, prohibiting open flames and using mobile phone calls in gas stations, and not refueling in plastic buckets, etc.

Because refueling and gas stations are now generally controlled by computers, high-intensity mobile phone signals will cause induction with computer equipment, and the instantaneous electronic friction between the two may ignite fuel vapor and cause an explosion.Therefore, it is recommended to connect the power of the shield to the battery of the car as much as possible to ensure that the device can work continuously.In recent years, with the rapid development of mobile phones, it is not uncommon for students to use mobile phones to affect their life and learning.It is still one or two o'clock, so in order to prevent students from playing mobile phones in the middle of the night and give themselves a better rest, many schools have to choose to install wifi jammer in their dormitories.

On the other hand, the customer knew that he could not use the mobile phone in the gas station, but he was lucky, and one-sidedly believed that the accident would not happen when he was using the mobile phone, so he did not listen to the persuasion of the gas station staff and went his own way.Strictly speaking, vehicle anti-monitoring and anti-tracking is a comprehensive professional discipline.It integrates communication engineering, radio technology, electromagnetic research, information science, network security, psychology and other disciplines.If the car turns off halfway, the jammer gps will definitely be powered off, then the location information of the car will be exposed again.

As long as the RF spark lasts for more than one microsecond and the energy is greater than 6 milliwatts, it will ignite the methane-air mixture.So is it enough to put a high-power mobile signal jammer? Is every room in the school dormitory like a school exam room? Actually, how to select and install it is explained below.The cell phone signal jammer gps in the school dormitory are mainly used at noon and evening when students are resting.The wifi jammer gps can be big or small, and there are many channels in any frequency band of mobile communication.Obviously, the school's behavior is mild and does not affect students' freedom of communication and expression.

Some students often use their mobile phones to surf the Internet in bed, and some even use their mobile phones to surf the Internet in the middle of the night.At the same time, in order to make the communication signal clearer, the frequency of mobile phone use is very high, and the transmission power is relatively strong.Since gasoline is a volatile substance, in the combustible danger area formed by the leakage of oil and gas tanks and natural gas pipelines, the radio frequency sparks generated by mobile phones can easily cause explosions and lead to disasters.When RF current circulates between metal conductors, RF sparks will be generated in case of corrosion or poor contact.

This type of jammer gps can basically be powered by the cigarette lighter, so after being installed in the car, it must be ensured that the jammer GSM is always in working state.At present, the main way for gas stations to prohibit customers from using mobile phone calls at gas stations is to persuade, but sometimes the effect of persuasion is not ideal.The current required to ignite the fuel gas is very small, and the static current generated by the mobile phone in the working state can completely reach this limit.Although it meets the national standard, it still poses a serious threat to refueling and gas stations.

That is to say, there is no need to shield the mobile phone signal 24 hours a day, so the shielding device of the ordinary power supply such as the external adapter is also optional.As a radio communication tool, the mobile phone emits radio waves, which can induce radio frequency currents in the antenna that receives the radio.Why can't you make phone calls in the gas station? Some people think that it is alarmist that a mobile phone can cause an explosion at a gas station, and they have never heard of an explosion caused by a mobile phone.First of all, people have misunderstandings about the safety hazards caused by using mobile phones in gas stations.

Teacher suspended for blocking students' cellphones

LAND O' LAKES, Fla. --The suspension of a science teacher in Florida has been enforced due to his utilization of a signal jammers to impede his students from utilizing their cellphones during class.

Dean Liptak, as reported by CBS Tampa affiliate WTSP-TV, aimed to divert students' attention from their phones and encourage them to concentrate on their lessons.

The decision to impose a five-day, unpaid suspension on Liptak was approved by the school board members in Pasco County on Tuesday. Liptak, without contesting, accepted the decision.

The activation of the mobile signal jammer in his Fivay High School classroom by Liptak has been confirmed by officials, spanning from March 31 to April 2.

In his statement to the school district investigator, he clarified that he had no intention of causing any trouble. He believed that the jammers were permissible as long as they were not intended for any harmful purposes.

Verizon's decision not to press charges against him has been acknowledged by the district, as reported by WTSP.

In a formal reprimand letter, Superintendent Kurt Browning highlighted the potential violation of federal law by Liptak and the possible interference caused by signal jamming, which could have hindered emergency calls to 911.

"Verizon had come to the school saying someone had a jamming device, because the cell phone service was being interrupted in the area," WTSP quotew Pasco County School District spokesperson Linda Cobbe as saying.

According to Cobbe, Liptak's jamming device successfully impeded communication to the cell tower located on the Fivay High campus.

The installation of cellphone signal jammers in steering wheels is long overdue.

Using a mobile phone while driving is against the law in California and several other states, with at least twelve states enforcing this regulation. However, despite its illegality, individuals continue to engage in this behavior.

It is a common occurrence to witness individuals who lack consideration and entitlement, jeopardizing their own safety and that of others by engaging in conversations or texting while driving on a daily basis.

According to the National Highway Traffic Safety Administration, a total of 37,133 individuals lost their lives in motor vehicle accidents last year, with over 3,000 of these fatalities attributed to distracted drivers. Furthermore, each year, numerous individuals suffer injuries due to drivers diverting their attention away from the road.

I contacted the Alliance of Automobile Manufacturers, an industry association, to gain insight into the stance of car manufacturers. According to Bryan Goodman, a representative of the organization, automakers consider this issue with utmost seriousness.

“We can all agree that hands on the wheel and eyes on the road continue to be critical to safe driving,” he said, adding that cellphones “were never designed to be used while driving.”

It is evident that distracted driving poses a significant threat to public safety, as the number of annual fatalities surpasses those caused by the Sept. 11 terrorist attacks.

Protecting your phone from unauthorized tracking or hacking is of utmost importance. However, by utilizing a Faraday pouch, you can effectively vanish from the digital landscape, shielding your device from any potential threats signal jammer device.

ALBERT EINSTEIN KEPT a portrait of the 19th-century scientist Michael Faraday on his wall, alongside a picture of Isaac Newton. Genius recognizes genius: Faraday's many discoveries led to electric motors, to electricity being put to practical use in technology, and to the concept of electromagnetic fields in physics. Faraday also figured out that an enclosure made of a mesh of conductive metal can absorb and redistribute electromagnetic interference. It is this work that's honored every time someone slips a cell phone into a pouch coated with metal, made for the specific purpose of preventing signals from getting in or out. The low-tech hack shields phones from digital buttinskies by blocking cellular signals, Wi-Fi, GPS, NFC, RFID, and Bluetooth. Privacy-craving citizens can put their phone into a Faraday pouch like this, where a metal lining renders the device inside invisible to snoops. “The biggest threat is a law enforcement agency using the signals on your phone to prove you were at a protest or demonstration that they decide later is illegal, and using that information to arrest you,” says Cooper Quintin, a security researcher with the Electronic Frontier Foundation, a nonprofit digital rights group. He doesn’t believe a Faraday cage would protect a phone any better than turning it off or putting it into airplane mode, but says the cage’s advantage is that it’s harder to forget or screw up. If you know you're the forgetful type, though, or just don't trust airplane mode on your phone, a Faraday cage means your vanishing act is in the bag mobile signal jammer.

→ With its three layers of nickel- and copper-coated fabric, the Faraday cage provides superior protection when compared to a single-layered design.

→ The efficacy of the metal fabric in suppressing signals would be compromised due to the damage caused by regular use; nevertheless, the inclusion of a soft liner shields it from abrasion.

→ To shield the phone from jolts and falls, a thin cotton padding layer is incorporated within the leather or nylon outer shell.

→ Should you prefer the convenience of a pre-made pouch, you can find them readily available on Amazon.

Despite the presence of cellphone jammers within the nation's correctional facilities, incarcerated criminals continue to find ways to communicate with individuals outside the prison walls.

This is the view of senior prison officials who tell the Sunday Express that even though the signal blockers (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.

Cellular signal blockers are currently employed, although their effectiveness is enhanced when combined with other technologies such as Wi-Fi jammers. This phenomenon has been observed in various jurisdictions, yet its full potential remains untapped in our own.

Prisoners will possess cellphones and tablets, yet they will be unable to make direct calls. However, they can utilize 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 applications such as WhatsApp, Facebook, and Instagram. Consequently, the matter of communicating with the outside world remains unresolved. Communication continues to persist.

“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.

Additionally, the Sunday Express has informed us that the jammers, which are utilized and controlled within the premises of the Prison Service, are actually overseen by a third party.

Acting Prisons Commissioner Deopersad Ramoutar refrained from providing a direct response to the inquiries posed to him regarding the effectiveness of the cellphone jammers. He stated that such information is privileged and falls outside the scope of the Prison Service's responsibilities.

The Sunday Express was informed by other senior officials that they continue to be operational.

At the Maximum Security Prison in Arouca, authorities discovered and confiscated a number of prohibited items, including a Wi-Fi box.

The officers were given information that guided them to the cells situated in the B Division of the prison.

During the investigation, thorough searches were carried out, leading the police to discover and confiscate a bag in a specific cell adjacent to the toilet area. This bag contained 53 grammes of marijuana, along with cellphones and the Wi-Fi box.

In an alternate compartment, law enforcement discovered and confiscated a pouch containing 104 packs of cigarettes and marijuana, with a combined weight of 241 grams.

The items seized were claimed by two prisoners.

Prison officers raised apprehensions on Friday regarding the utilization of drones above correctional facilities. A senior officer emphasized that this matter is a pressing concern that must be promptly dealt with.

The presence of a single undetected drone, capable of delivering knives or firearms, could lead to an extremely grave scenario. Up until now, the items we have confiscated have been illicit goods such as cigarettes, marijuana, mobile phones, and chargers. However, the failure to intercept even one drone could pose a significant threat to both the prison and the nation.

Ramoutar highlighted that the Prison Service has acknowledged a surge in the usage of drones near penitentiaries, particularly in the past year, prompting them to take appropriate measures.

Using the assistance of different branches within the National Security portfolio, he stated that the majority of the objects that were thrown over prison walls were confiscated before they could be obtained by the inmates.

The Communications Act of 1934, as amended, prohibits the operation, manufacture, importation, marketing, and sale of equipment designed to jam or otherwise interfere with authorized radio communications, such as radar, global positioning system (GPS), and cell phone communications. These jamming device pose significant risks to public safety and potentially compromise other radio communications services.

• Section 301 of the Act requires a valid FCC authorization or license for the operation of radio transmitting equipment. Unlike other radio transmitting equipment, jamming equipment cannot be authorized by the FCC because the main purpose of jamming equipment is to interfere with radio communications.


• Section 302(b) of the Act prohibits the manufacture, importation, sale, offer for sale, or operation of devices that do not comply with the equipment authorization rules. Jammers do not comply with the rules because they are designed to jam or disrupt authorized communications.


• Section 333 of the Act prohibits willful or malicious interference with any radio communications of any station licensed by or authorized under the Act, or operated by the United States Government.


• Consequently, the operation of jamming equipment violates Sections 301 and 333 of the Act. The manufacture, importation, sale, or offer for sale of jamming equipment violates Section 302(b) of the Act.


• As a result of past enforcement efforts, jammers are rarely marketed by domestic entities and now are almost exclusively marketed online by foreign retailers. When the retailer is located outside of U.S. territory, The Hague Convention on Service Abroad may apply and require that Commission documents only be served in a manner prescribed by authorities in the retailer’s country of residence.


• The Enforcement Bureau has released Enforcement Advisories specifically designed to inform retailers, importers, consumers, and state and local government agencies that jammers are illegal and may not be operated, marketed or imported into the United States. The Advisories warn that violators risk substantial civil and criminal penalties.
