The European Football Championship is one of the most prestigious football tournaments in the world, attracting millions of fans and widespread attention from the media and stakeholders. With the stakes high, the integrity of the tournament is of paramount importance. One of the tools used to ensure this integrity is the deployment of cell phone jammers. These devices are essential to preventing players from manipulating matches, a significant issue in professional sports.


Match-fixing refers to the manipulation of the results of sporting events for financial gain, often orchestrated by gamblers and criminal organizations. This illegal activity undermines the integrity of the sport, reduces fan trust, and can have serious legal and financial consequences. Players, referees, and other officials may be contacted and coerced into participating in match-fixing schemes through a variety of means, including cell phones.




How Cell Phone Jammers Work



Cell phone jammers interfere with communications by sending signals on the same frequency as mobile phones, creating a "noise" that clogs communication channels. These devices can be used to block phone calls, text messages, and data transmissions within a specific area. By blocking mobile communications, signal blocker can thwart attempts to influence or coerce players and officials at critical moments, such as before or during a match.



Implementation at the European Football Championship



Mobile phone jammers were implemented as a strategic measure to preserve the integrity of the competition during the European Championship.



Here are their typical uses:




  • Dressing Rooms: Jammers are placed in the players’ dressing rooms to prevent players from receiving or sending messages before a match or at half-time.

  • Referee Areas: Ensure referees are not contacted during critical moments.

  • Team Benches: Prevent communication with the outside world during matches.

  • Jammers are activated during specific periods when the risk of communications for match manipulation is highest, such as pre-match preparation, half-time and during matches.

  • Clearly communicate the presence of jammers to players, referees and staff. This transparency helps manage expectations and ensures all parties understand the importance of these measures in maintaining the integrity of the sport.



Advantages of using mobile phone jammers




  1. By blocking potential match-fixers from accessing players and referees, jammers reduce the risk of undue influence on match outcomes.

  2. Players and officials can focus fully on the game without the distraction of mobile devices, creating a fairer, more competitive environment.

  3. The use of jammers sends a strong message that UEFA is committed to maintaining the highest standards of integrity in the sport of football.

  4. Knowing that communications are being monitored and potentially blocked acts as a deterrent to those who would like to manipulate matches.

An oilfield company faces a May deadline to contest a $126,000 fine assessed by the Federal Communications Commission against the company for jamming signal cellphone calls.


that on April 9, the FCC adopted a notice of apparent liability against Taylor Oilfield Manufacturing Inc. of Broussard, accusing Taylor of using four cellular phone jammers to curtail cellphone use by employees.




Company officials told the FCC the cell jammers, which disrupted cellphone usage, were used to prevent employees from using cellphones at work.


Taylor was given 30 days from April 9 to pay the penalty or respond to the FCC in writing as to why the fine should be canceled or reduced.


Taylor officials did not respond to phone calls seeking comment.


The case began after the FCC received a tip and sent an agent to the company site in Broussard in May 2012. The FCC notice said company officials confirmed use of four cell jammers and possession of a fifth cell jammer, which was not then in use.


Use of cell jammers is prohibited in the United States, and the FCC prohibits companies from importing cell jammers from outside the country. The Broussard company said it bought its cell jammers from overseas, the FCC said.


“These unlawful jammer operations posed a tangible public safety hazard by potentially blocking authorized communications” such as 911 emergency calls and other law enforcement communications, the FCC said in its notice to the company. Cell jammers can also adversely affect global positioning system signals.


Taylor representatives told the FCC it tried to block employee cellphone use after a near accident the company said was partly connected to an employee using a cellphone, according to FCC documents.

We heard from our friend Charles Curry of Chronos Technology over the long weekend. He had a “yes and” to last week’s post about a jammer company with a new product line. – Full disclosure, Chronos has long be an RNTF corporate member.


Charles is semi-retired but still keeps an eye on the jammer market.


He and Chronos have quite the history detecting GNSS interference and recommending ways to mitigate it. They have worked with police departments advised governments, and published several papers.


Their “Sentinel Project – Report on GNSS Vulnerabilities” was issued in 2014. Most of its findings and recommendations are as pertinent today as they were seven years ago.


Here is Charles’ list of 100 active websites selling GNSS/
GPS jamming equipment, and a list of over 200 that used to do so, but that have links that appear inactive.


Charles said there are more sites, he just stopped when he got to 100. – Yeah, a hundred ought to make the point reasonably well…




FCC investigates Amazon over alleged marketing of wireless signal jammers


The FCC is the federal agency that has the authority to enforce the law on this, and establish and enforce supporting regulations.


The Federal Communications Commission (FCC) says it is taking action to enforce the law against marketing, selling, and using wireless jammers, including those that target GPS/GNSS. While reports do not mention anything about spoofing, it is against the law also.


What Else to Know:



  • While news reports do not mention anything about the FCC addressing spoofing, that is against the law also.

  • Unfortunately, over the last 20 years the FCC’s enforcement bureau has been greatly reduced in size while the incidents of accidental (also not allowed) and intentional interference with GPS has greatly increased.

  • While it is illegal to market, sell, and use jamming devices, they are not illegal to own.

  • The U.S. does not have a systematic way to detect interference with GPS/GNSS signals. The 2022 interference event at Denver lasted 33 hours before it was geo-located and terminated. The event at Dallas the same year lasted for 24 hours and the source was never located.

  • We looked for the original statement from the FCC spokesperson, but were unable to find it on the FCC site. It looks as though it was made directly to NBC in response to their inquiry.

What’s the context?


US prison officials harness new technology to crack down on contraband cellphones but some still want powers to jam signals



  • South Carolina programme shuts off more than 800 phones

  • Federal action on broader signal jamming tech seen as unlikely

  • Activists raise privacy, rights concerns for prisoners

Digital privacy rights advocates and tech experts say even solutions less far-reaching than full-blown signal jamming - like the South Carolina pilot - threaten to trample on the rights of prisoners by, for example, sharing legally protected information with private phone companies or carriers.


Digital rights groups have long raised concerns over the push for cellphone jamming systems in prisons, describing them as overreach.


Under federal law, state and local facilities are not allowed to use jamming technology, which is opposed by the telecommunications industry amid concerns that it could knock out signals in areas surrounding prisons.


The Federal Communications Commission (FCC), which regulates communications technology in the U.S., has been wary of signing off on full-blown signal jamming but cleared the way within the last few years for states like South Carolina to implement so-called "contraband interdiction systems."


Stirling is convinced signal jamming is a solid option but does not think it will be authorised in state prisons. It is already allowed in federal institutions.


"I would love to get jamming – I don't see it happening, unfortunately," he said.


Asked if the FCC was contemplating changes, a spokesperson pointed to the federal law banning jamming devices.


Albert Fox Cahn, founder of the Surveillance Technology Oversight Project (S.T.O.P.), says both jamming and interdiction systems like the one used in South Carolina are "chilling options" that could have unintended consequences.

NBC News reported that online retailers and drone technology companies are marketing radio frequency jammers as drone deterrence or privacy tools, bypassing laws that prohibit the sale of such devices in the United States.


The warning issued by the Federal Communications Commission (FCC) says signal jamming devices can block emergency calls and pose a serious risk to public safety communications, as well as interfere with other forms of daily communication and air navigation systems.


"The use of telephone jammers, GPS jammers, or other signal jamming devices designed to intentionally block, interfere with, or interfere with authorized radio communications violates federal law," the FCC said. "There are no exemptions for use in businesses, classrooms, homes or vehicles. Local law enforcement agencies do not have independent powers to use jamming devices; With certain limited exceptions, use by federal law enforcement agencies is authorized under applicable statute."


The FCC's warning also states that "it is illegal to advertise, sell, distribute, import, or otherwise market interfering devices to consumers in the United States."


But NBC reported that Amazon third-party sellers, independent online stores based in China, and small domestic companies specializing in drone-related equipment flouted the law. The FCC told NBC that it is investigating the sale of jammers, including on Amazon.


As part of its investigation, NBC interviewed the CEO of an American company that offers portable anti-drone RF jamming devices online. The CEO told NBC that the devices are easy for consumers to buy if they have the money, but they are mainly seeing interest from large corporations and government agencies as they prepare for domestic drone terrorism.

In a statement by the Los Angeles Police Department, officers warn that a group in Wilshire is using wifi jamming technology to disarm surveillance cameras and alarm systems that rely on Wi-Fi.


(TNS) — A group of thieves have been outsmarting smart devices across the Los Angeles area, authorities said.



8 Bands Jammer Device

In a March 4 statement by the Los Angeles Police Department, officers warn that a group in Wilshire is using Wi-Fi jamming technology to disarm surveillance cameras and alarm systems that rely on Wi-Fi.


This swarm of tech-savvy robberies in California is part of a larger “smart” crime wave happening nationwide. Last year, police in Minnesota and Connecticut issued similar warnings to residents when groups of Wi-Fi jamming thieves made their rounds. And those are just two examples of many.


While the Federal Communications Commission has banned Wi-Fi jamming devices, this doesn’t stop criminals from buying them cheaply, KARE11 reported. Wi-Fi jamming devices don’t necessarily deactivate devices, but work by overloading the network the devices are connected to.


“These (signal jamming) devices create traffic jams for the radio transmitter so that real traffic cannot get through,” cybersecurity expert Mark Lanterman told the outlet.


“If you are going to use a Wi-Fi camera for your front door, perhaps consider using a hardline camera inside your home,” he said. Wired cameras connected via Ethernet cables do not rely on Wi-Fi networks and would not be disrupted by a Wi-Fi jammer.


Los Angeles police also recommends hard wiring burglary alarm systems


While “smart” technology may be part of the problem, it may also have a hand in the solution, according to Tom’s Hardware. Officials recommend using timers or smart home devices to make it look like someone is home while you are away. Some smart home technology also comes with the ability to alert users if the signal or connection has been interrupted.


Tom’s Hardware also recommends connecting surveillance devices that store camera footage directly on your device, and not just to a cloud storage system. By having a camera that records to itself, you’ll have footage saved during a Wi-Fi disruption.


The LAPD also encourages people to stay vigilant by locking their doors, relying on neighbors to check on things when away and reporting any strange activity, including suspicious vehicles with temporary or dealer plates.

The FCC says illegal devices that block cell phone signals could pose a security risk.


The FCC has noticed a rise in people selling "jammers." The devices can block cell phone calls, text messages, Wi-Fi networks and GPS systems and could be used to cause chaos in public places.


The small, battery-powered devices can be used to create "blind spots" in a small area (usually about 30 feet) and have been used by movie theaters, restaurants and schools to prevent people from using their phones. But they can also cut off 911 calls, interfere with navigation near airports and have been used to jam radio communications near police stations. FCC officials say they have noticed an increase in the flow of jammers, which are banned by federal law, into the U.S. Many of the cheaper versions, which sell for as little as $25, are imported from Asia, according to the agency.



It is illegal to sell, advertise, use or import jammers under the Communications Act of 1934, which prohibits blocking radio communications in public.


Earlier this week, the FCC issued subpoenas to eight individuals and companies that posted ads for jammers on Craigslist.


The FCC said cities including Orlando, Philadelphia, Austin, Mississippi, Charlotte, North Carolina, Washington, D.C., Cincinnati and Corpus Christi, Texas, advertised jammers on the site. Officials said they do not believe the cases are related.


"Simply posting an ad for a signal jammers on a site like Craigslist.org is a violation of federal law. Signal jammers are contraband for a reason," Michele Ellison, director of the FCC's enforcement bureau, said in a statement. "One person's moment of peace or privacy could jeopardize the safety and well-being of others."


According to the citations, most sellers advertised the jammers as a way to take an "undisturbed nap" on the bus, quiet a classroom or keep your area "free of interference," without mentioning the more nefarious uses the devices could be used for.


"We are increasingly concerned that individual consumers operating jammer devices do not appear to understand the serious consequences of using jammers," one of the citations read. "Instead, these operators mistakenly believed that their illegal operations were a matter of personal convenience or should be excused."


But the FCC said at least one seller appeared to know that jammers were contraband.


Keith Grabowski allegedly advertised on Philadelphia Craigslist for sale a "cell phone blocker, wifi blocker" for $300. In his ad, he said that "due to the nature of this item, we are revealing very few details," that the jammer was "not a toy," and that "I just wanted to get rid of it as quickly as possible."


"The nature of the ad suggests that Mr. Grabowski knew about the sensitive and/or illegal nature of the equipment he was selling on Craigslist," the citation reads.


People who receive the ticket have 15 days to remove the ad from the site and provide the FCC with information about where the jammer was purchased and to whom it was sold. Simply posting an ad for the sale of a jammer could result in a fine of more than $100,000.


The FCC has set up a "jammer tip line" for people to report to the agency people who may be selling or using jammers.


"We intend to take increasingly tough enforcement action against offenders," Ellison said. "If we find you selling or operating a jammer, you will be punished."

Expanding the scope of cell phone jammer applications


Cell phone jammers were initially created for law enforcement to intercept messages from terrorists and criminals. Over time, they have undergone significant advancements. Nowadays, they play a crucial role not only in combating terrorism but also in various official and civilian applications. Their capability to block communications as a precautionary step against organized crime and to disable remote-controlled explosive devices makes them essential in contemporary security measures. Furthermore, there have been instances where signal jammers have prevented attempts to assassinate prominent figures, underscoring their vital function in high-risk security situations.



Technological advances enhance jamming capabilities


The efficiency of cell phone jammers is attributed to the sophisticated technology powering them. These gadgets emit precise signals that disrupt the functioning of the remote-controlled receiver, thus thwarting the implementation of any programmed instructions. It is crucial to note that this interference is limited to a specified zone, guaranteeing that devices beyond this shielded region remain unaffected. This accuracy is vital for upholding uninterrupted communication across a broader expanse while safeguarding the intended area.


Jammers employ uniquely coded signals to trick GSM device receivers, stopping mobile phones from linking up with their respective base stations. This advanced method guarantees that any effort to communicate through a cell phone within the jammed area is successfully disrupted, while authorized communications beyond the jammed area continue without interruption.


Applications Beyond Terrorism



  1. Educational Institutions:

    - Cell phone jammers are increasingly used in educational institutions to prevent cheating in exams. By blocking signals within exam rooms, authorities can ensure a fair exam environment.

  2. Prisons and Detention Centers:

    - In detention centers, jammers are essential to prevent inmates from making unauthorized calls, which could coordinate criminal activity outside the facility.

  3. Corporate Security:

    - Companies use jammers to protect sensitive information during high-level meetings, ensuring that no unauthorized recording or transmission occurs.

  4. Public Events and Venues:

    - During large public events such as concerts or sporting events, jammers can prevent disruptions and ensure the safety of attendees by blocking potential threats such as remote control devices.

  5. Hospitals:

    - In medical settings, jammers help maintain security in areas where cell phone signals could interfere with sensitive medical equipment.




It is evident that cell phone jammers offer numerous advantages; however, their utilization necessitates a careful balance between ethical and legal factors. The deployment of jammers is subject to regulations that differ across countries and regions. In numerous locations, their usage is restricted to authorized individuals and specific situations to prevent any potential abuse and guarantee uninterrupted access to emergency communications.


With the continuous advancement of technology, it is expected that cell phone jammers will undergo further improvements. These future enhancements may involve refining the targeting capabilities to minimize any unintended disruptions, enhancing the portability for quick deployment in dynamic scenarios, and strengthening the encryption to ensure that jamming signals remain impenetrable.


Cell phone jammers have transformed from a niche law enforcement tool to a versatile device with widespread use in security, privacy, and public safety. By leveraging advanced technology, these devices play a vital role in protecting against threats ranging from terrorism to cheating on exams. However, their use must be strictly regulated to balance security needs with individual rights and freedoms. As we move forward, the continued development of jamming technology promises to enhance our ability to protect and secure society from emerging challenges.

The individual who fitted a laser jamming device in his commercial vehicle to evade speeding fines has received a suspended prison term, been instructed to pay a fine of £3000, and subjected to a two-month curfew.


Jason Moore was convicted by a jury at Swansea Crown Court for obstructing justice by installing a Laser Star jamming device on a VW Transporter van to obstruct a laser speed camera operator from Dyfed-Powys Police in determining the vehicle's speed.


James Hartson, the prosecutor, informed the court that in September 2018, the van was observed traveling at a high rate of speed as it neared the speed camera near Nantyci Showground on the A40, St Clears, heading towards Camarthen.


The camera operator encountered an error message while trying to measure the speed of the vehicle. Despite this, the operator had received training from Road Safety Support experts to identify the specific conditions that could trigger such an error message.


Dyfed-Powys Police, as part of Road Safety Support, enlisted the expertise of Steve Callaghan, a forensic video analyst and laser jammers specialist employed by the company.


Mr. Callaghan received a copy of the video and verified the presence of a suspicious device in the footage. Additionally, he observed that the laser signal jammers emitted light from the van's grille while error messages were being displayed by the laser speedmeter.


Following Mr. Callaghan's initial assessment and recommendations to Dyfed-Powys Police, the van was retrieved in order to conduct testing on the device and gather evidence.


A comprehensive report was compiled detailing the examination results and the circumstances surrounding the incident, during which the speed could not be determined. Road Safety Support determined that the van was traveling at a speed of 72 mph, exceeding its maximum permitted speed of 60 mph.


Mr. Moore stated that he was unaware of the Laser Star jamming system's ability to interfere with the speed measurement feature of a police speedmeter. He asserted that he purchased the device specifically for its parking sensor function.


Mr. Moore selected David Winstanley, a former police collision investigator, who asserted his proficiency in laser and video systems, to serve as his expert witness.



Mr. Winstanley emphasized that the Laser Star should be marketed as a 'parking sensor' rather than being viewed primarily as a laser jamming device.


Mr. Callaghan clarified that utilizing a laser beam for identifying parking obstacles was completely unsuitable and mostly ineffective. He pointed out that a parking sensor does not have to be set to disrupt a laser speedmeter in any circumstance. Additionally, the Laser Star is advertised as being able to disrupt speed cameras in its instructions and marketing materials, which is not a feature of a parking sensor.


Mr. Moore further mentioned in his explanation that the security firm he was employed by required staff to cover the costs of any harm inflicted on company vehicles. He argued that he installed the device to minimize the likelihood of damage.


Moore was convicted by a jury and received a sentence at Swansea Crown Court on October 18, 2021.


Judge Vosper QC deemed Moore's defense as baseless, expressing no astonishment over the jury's dismissal of it.


Moore received a suspended 32-week custodial sentence, which will remain in effect for a period of 2 years. Additionally, he has been instructed to settle costs and fines amounting to £3,000, and a curfew lasting two months has been imposed upon him.


Can police tell if you have a laser jammer?


The utilization of a lidar gun by the police, directed towards a vehicle, will result in the device displaying either "no response" or cosine error. In the event of such an error, the police will be unable to determine whether the vehicle is equipped with a laser jammer or if they are simply not targeting the vehicle accurately. Consequently, this grants the driver an opportunity to modify their speed before the police can retrieve the data once more.


Since police need to be stationary and able to see a vehicle at close range without cover for lidar to work properly, if police receive a false response the first time they fire their lidar gun, the targeted driver will likely have time to adjust his speed when out of range. Lidar is most often used by motorcycle police or identifiable patrol cars, who use it most effectively on major roads, which limits when and where they can be used. In the case of heavy traffic, the police lidar gun is very effective at focusing on the vehicle and instantly calculating its speed, distance and direction.

Why use cell phone blockers?


Signal jammers are deemed essential in locations where adhering to cellphone etiquette proves challenging; however, their prohibition stems from the potential hazards they present to public safety and communication infrastructures.


Are cell phone blockers legal?


In South Africa, the preservation of communication network integrity is crucial, leading to the strict prohibition of mobile jammers by law. Similar to numerous other regions worldwide, the utilization of such devices goes against the legal structure put in place to uphold public safety and guarantee communication reliability.


The South African signal jammers are considered illegal due to their inherent interference with authorized radio communications. Their disruption of signal transmission between mobile devices and cell towers poses a substantial threat to public safety. This interference can obstruct crucial emergency calls, cause delays in response times, and potentially put lives at risk. Furthermore, signal jammers have the capability to disrupt law enforcement communications, impede the effectiveness of police operations, and jeopardize public safety.


Does a signal booster work against cell phone jammers?


Regrettably, the signal booster proves to be ineffective when faced with a signal jammer. This is primarily due to the fact that signal jammers intentionally disrupt the transmission of cellular signals, thereby interfering with the very signal that the signal booster is intended to enhance.


A signal booster's purpose is to receive a cellular signal from outside a building or vehicle, boost it, and transmit the emer signal within a specific area. But, when a signal jammer is in use, it disrupts or replaces natural cellular signals, hindering the signal booster's ability to receive and amplify them effectively.


Detect and respond to cell phone jammers


Detecting signal jammers poses a significant challenge for the average consumer due to their stealthy nature and lack of clear indicators. Service interruptions or sudden loss of connection may suggest the presence of jammers, but these signs can also be caused by other factors like network congestion or technical issues.


Specialized equipment or expertise is often necessary to accurately determine the exact location of a signal jammer. Most consumers do not have access to advanced spectrum analyzers or RF detectors, which are typically required for pinpointing the source of interference. Therefore, if there are suspicions of illegal interference activities, it is recommended to seek help from law enforcement agencies or relevant regulatory bodies. These authorities possess the necessary resources and expertise to effectively investigate and resolve such incidents.
