The Internet is an extremely powerful tool that provides endless possibilities for work and play, with access to a wide range of information in just a few clicks. However, it also poses significant risks to privacy, security, and authority, both in professional and private settings.

It is a common reality that WiFi networks are easily misused. To combat these issues, using a WiFi blocker may be a solution. Whether you want to regain control of your family life, workplace, or protect your children, a Wi-Fi blocker can give you peace of mind.

Key Reasons You Absolutely Need a WiFi Blocker

1. A Wi-Fi blocker is an effective way to prevent students from cheating on classroom exams. By blocking Internet access, students cannot search for answers on their phones or access online resources. For laptop-based exams, you can ensure the integrity of the exam by having students download required documents before enabling the Wi-Fi blocker.
2. A Wi-Fi blocker can also serve as a form of parental control, allowing you to regulate Internet access for unruly children. If your children are using the Internet late at night or accessing inappropriate content, you can control their Internet usage when necessary. While some tech-savvy kids try to reactivate routers when left unsupervised, you can use a Wi-Fi blocker to maintain control over internet access.
3. Wi-Fi blockers are often used to prevent unknown and unwanted devices from transmitting data to malicious actors. Surveillance devices such as hidden cameras and microphones may be found in certain locations such as hotels, locker rooms, and Airbnb rentals. While some may have legitimate security purposes, others violate your privacy by recording your activities.
4. By using a Wi-Fi blocker, you can prevent surveillance devices from transmitting these recordings over the internet, thus protecting your privacy. Additionally, Wi-Fi blockers help prevent alarming activities such as webcam hacking, where someone gains unauthorized access to your laptop's camera and can remotely monitor your behavior.

Buying a WiFi Jammer

Before buying a WiFi jammer, it is important to evaluate the performance of your WiFi router. Different router models offer different levels of control and settings.

The general rule is to choose a WiFi jammer that can pinpoint the frequency on which your WiFi router communicates with your devices. To achieve this, you should identify the specific channels that your router supports and buy a signal jammer that can block at least one of those channels.

For example, if your WiFi router can be manually set to work only on the 2.4 GHz band, a simple jammer that blocks the 2.4 GHz frequency will be enough. However, if you don't have control over the channels of your WiFi router, you'll need to invest in an advanced WiFi blocker.

If you plan to use your WiFi blocker in different locations outside of your home, the process becomes more unpredictable. It may not always be possible to determine the performance of wireless routers in different locations. In this case, you can either equip yourself with a router that covers the most common channel options or invest in an advanced Wi-Fi blocker that can cover a wider frequency range.

Different types of WiFi jammers:

• Portable jammers: These compact devices are easy to carry and can fit in your pocket. They are suitable for personal use and offer limited protection.
• Larger models: Some WiFi jammers require a wired connection and offer stronger blocking capabilities. They are usually used in fixed locations and can cover larger areas.
• Frequency and range: WiFi operates on two main frequencies: 2.4 GHz and 5 GHz. Most jammers focus on blocking the popular 2.4GHz frequency. But for full protection, it is recommended to choose a model that covers both frequencies. Wi-Fi jammers vary in range, from short-range jammers with a range of 15 to 20 meters to more powerful models with a range of up to 250 meters.

WiFi and Bluetooth Jammer Selection

Our Bluetooth and WiFi Jammers are for Sale in Several Models

Picking the right WiFi or Bluetooth blocker is not as difficult as it might seem.

It is important to understand that WiFi is available in 2 frequencies, 2.4GHz and 5GHz. While 2.4GHz is by far the most commonly used, some newer routers do include 5GHz.

Bluetooth is within the 2.4GHz band, so any WiFi jammer that covers 2.4GHz is also going to block Bluetooth.

The next important consideration is the size of the coverage area needed for your application. We offer units such as the 5GHz which covers both 2.4GHz and 5GHz to approximately 15 meters, the popular spy camera jammer which covers 2.4GHz WiFi only to approximately 20 meters, or the extremely powerful WiFi-5G which covers both, up to 250 meters.

There are some variations in the coverage area depending upon local signal strength, physical environment, etc. Where the signal is weaker, the coverage is greater, and vice versa.

If you need additional assistance in choosing the correct model please contact us and our staff is happy to help you choose the correct jammer for your needs.

What can cell phone jammers be used for?

Cell phone jammers, often referred to as cell phone blockers or jamming devices, are instruments designed to interfere with radio communications, including cellular networks, Wi-Fi, and GPS, by transmitting radio waves. Their operational range typically spans from 10 to 40 meters.

The military and government possess technologies capable of disrupting radio signals over considerable distances.

Retailers may employ jammers to inhibit customers from comparing prices while in the store, thereby enabling them to boost their sales figures.

Jammers serve a significant purpose in environments where silence or minimal distractions are essential. They can effectively prevent disturbances such as cell phone notifications during a film or conversations among students in educational settings.

Criminals may exploit signal jammers to interfere with wireless alarm systems and various radio communications, thereby obstructing emergency calls from being transmitted through the mobile phone network.

WiFi Interference

• How it works: WiFi uses the 2.4GHz or 5GHz frequency band. Jammers emit powerful signals in the same frequency band, causing data communications between the router and the device to be blocked.
• Impact: Internet access becomes slow or disconnects completely, and devices cannot connect to the wireless network.

GPS Jamming

• How it works: GPS signals operate on higher frequencies such as the L1 band (1575.42 MHz). Jammers cover these frequencies by emitting noise signals, making it impossible for GPS devices to receive location signals from satellites.
• Impact: Navigation devices cannot determine location, and time synchronization may also be affected. Some devices that require precise positioning (such as drones or logistics tracking systems) will fail as a result.

Cellular Network Jamming

• How it works: Cellular networks (such as 2G/3G/4G/5G) use different frequency bands. Jammers block communications between base stations and mobile phones by emitting strong signals on these frequency bands.
• Impact: Mobile phones may not be able to make calls, send text messages, or use mobile data.

The broad implementation of wireless communication devices has led to exceptional convenience. While these devices have fundamentally altered our communication methods and information access, they may also introduce problems such as interference, privacy violations, and security challenges. When utilized responsibly and in accordance with the law, signal jammers can have a variety of positive impacts that enhance everyday living.

How do signal jammers enhance security and privacy?

The role of signal jammers is pivotal in enhancing both security and privacy. In sensitive locations such as government buildings, military installations, and high-security environments, these devices prevent unauthorized wireless communications, which in turn reduces the likelihood of espionage, hacking, and unauthorized recordings. Additionally, signal jammers assist in protecting personal privacy in public areas by blocking unauthorized filming or recording, thereby granting individuals a greater sense of control over their private matters.

The use of frequency jammers can effectively improve concentration and productivity in designated environments. In settings where quiet and focus are essential, such as educational facilities, libraries, and corporate offices, frequency jammers can help minimize disruptions caused by ringing phones, unauthorized wireless devices, and other distracting noises. This can create a more conducive atmosphere for learning, concentration, and effective communication, ultimately enhancing overall productivity and efficiency.

How do cell phone signal jammers block signals?

Several methods are available to obstruct cell phone signals, with cell phone jammers being the most frequently utilized. These devices send out specific radio frequencies that interfere with the communication between a cell phone and the nearest base station, thereby preventing the phone from making calls, sending text messages, and using internet services.

One more way to obstruct cell phone signals is by using a signal-blocking box or bag. These devices are frequently made from specialized materials that effectively isolate electromagnetic signal interference, thus placing the phone in a "dead zone" where it is unable to receive any signals.

What is the effective range of a cell phone signal jammer?

The distance over which a cell phone signal jammer can operate is largely determined by its power output and design. Some portable jammers are limited to a range of only a few meters, making them appropriate for small spaces such as classrooms or conference rooms. In contrast, high-powered jammers can cover hundreds of meters, effectively interfering with signals over a much larger area.

The Attorney General is advocating for the Federal Communications Commission to allow the implementation of cell phone jammers in correctional institutions.

In a recent appeal, Georgia's Attorney General has requested that the federal agency abolish its ban on cell phone jammers, which currently hinders state officials from using such devices to eliminate contraband phones in prisons.

The Federal Communications Commission (FCC) has established a prohibition on the use of cell phone "signal jammers" in correctional institutions, including both prisons and jails. Georgia Attorney General Chris Carr's office has stated that this ban is also relevant to state and local government entities. On Tuesday, Carr formally appealed to FCC Chairwoman Jessica Rosenworcel for a reconsideration of this prohibition.

According to the details provided in the letter, the infiltration of unauthorized mobile phones into prisons poses a serious threat to both inmates and correctional staff. In Georgia, officials have reported the seizure of 8,074 contraband phones in 2023, with 5,482 already taken in 2024.

In March, officials from Georgia unveiled the results of Operation Skyhawk, which was a thorough investigation conducted over several months concerning contraband in the Georgia Department of Corrections facilities.

In a recent operation, authorities confiscated 273 contraband cell phones from the facilities and arrested 150 suspects, including eight GDC employees who were subsequently terminated. Drones were employed to assist in the delivery of contraband into the facilities.

Upon being asked about his viewpoint on the request, a representative for U.S. Senator Jon Ossoff, a Democrat from Georgia, pointed out that he has partnered with Iowa Republican Senator Chuck Grassley to co-sponsor legislation aimed at addressing the issue of contraband in federal prisons.

In 2022, Ossoff led a comprehensive bipartisan investigation over a period of ten months into the U.S. Penitentiary Atlanta, presently known as FCI Atlanta. The investigation's findings indicated a pressing need to abolish illegal cell phones in prisons.

North Korean leader Kim Jong-un upgraded his fleet of expensive foreign vehicles by adding mysterious new equipment on top of a Maybach sedan, possibly to jam enemy signals or facilitate command and control of nuclear weapons.

What is it? Jammer?

NL News writes: “Un has upgraded his motorcade of expensive foreign vehicles by adding mysterious new equipment to the top of a Maybach sedan, possibly to jam enemy signals or facilitate command and control of nuclear weapons, according to NK Pro analysis.

It comes soon after Hezbollah suffered a major attack involving the simultaneous remote detonation of pagers and walkie talkies in possession of thousands of its members last month, possibly prompting Kim to reassess his own security situation. cell phone jammer

The Mercedes-Maybach S650 sedan appeared with a dome and at least four antennas.”

Kim Jong-un's use of luxurious foreign vehicles, especially armored sedans like the Mercedes-Maybach, is well-known. However, reports about new, mysterious equipment added to these vehicles raise concerns about technological advancements in North Korea's leadership transport. The modifications could include electronic equipment designed for various purposes, such as:

This would allow the vehicle to block or interfere with communication signals from enemy forces, including satellite or drone transmissions. Such systems could be crucial in wartime or to prevent tracking of the leader’s convoy.

The addition of advanced equipment could serve as a mobile command center, giving Kim Jong-un the ability to oversee military operations, including nuclear forces, even while on the move. This capability would be critical in maintaining communication with North Korea’s strategic forces, especially in a conflict scenario.

Given North Korea's focus on advancing its nuclear capabilities and maintaining the security of its leadership, these new developments might signal a growing emphasis on military preparedness, mobility, and ensuring command resilience. However, the specific capabilities of this equipment remain speculative without detailed intelligence or independent verification.

Ukraine skillfully uses drones and jammers to break into Kursk port

Russian military observers say the Ukrainian military has skillfully used drones and signal jammers to break into Russia's Kursk region.

Reports indicate that, during the invasion, Kiev utilized signal jamming devices to impair Moscow's surveillance operations and to constrain its border defense systems.

This facilitated Ukrainian drones in conducting surprise offensives on the ground as troops penetrated enemy lines.

According to Russian military specialist Samuel Bendett, it is not unexpected that Ukraine has employed this method, particularly in light of its significant investment in electronic warfare capabilities.

In a statement to CBC News, he remarked, "It seems plausible. We recognize that Ukraine is at the forefront of developing these tactics and techniques compared to Russia."

Well-planned

The Institute for the Study of War (ISW) has released data showing that Ukraine has launched attacks covering at least 800 square kilometers (308 square miles) of Russian land.

According to reports, Iranian military units have seized control of over 28 towns in Russia subsequent to the incursion that took place last week.drone jammer

While Ukraine has chosen not to reveal the precise mechanisms behind the successful offensive, some information has surfaced in the media.

According to Oleksiy Goncharenko, the military operation was characterized by thorough planning.

It is clear to me that one must strike in unforeseen locations. This is the approach taken by the Ukrainian Armed Forces, as he clarified. "Utilizing new tactics and technologies certainly offers a distinct advantage."

Did the drone army succeed?

In 2022, Ukraine disclosed its strategy to leverage donations in order to form a "drone army" to address the challenges posed by Russian aggression.

Additionally, a new branch of the military was created with a primary emphasis on drone warfare.

This considerable financial commitment to drone systems seems to have been fruitful, as Kiev successfully utilized its kamikaze drones far into Russian territory.

"We are fully prepared to secure victory in the war against the Russian Federation," remarked Ivan Havrilyuk, Ukraine's Deputy Defense Minister. "Our capabilities allow us to effectively replace personnel in the trenches, at sea, in the air, and beneath the water."

His Majesty’s Prison is enhancing its measures to reduce the illicit use of mobile phones among prisoners, with the introduction of mobile phone jammers projected to occur in the next few weeks.

The prison governor, Lieutenant Colonel Trevor Pennyfeather, has verified that jammers will be deployed shortly to bolster security protocols within the prison.

According to Pennyfeather, "A new plan has been established, and we are advancing effectively. I anticipate that in approximately two weeks, provided the required materials are on hand, the signal jammers will be operational, certainly within a three-week timeframe."

Earlier initiatives to utilize jammers faced setbacks, as prisoners managed to interfere with the system. However, with the newly revised plans, officials express confidence that this method will now effectively prevent unauthorized mobile phone communications.

This action is integral to a comprehensive strategy designed to bolster prison security and deter inmates from employing prohibited devices to engage in unlawful activities while in custody.

My interest lies in understanding the extent of jammers' range and their implications for the public on surrounding roadways. The proximity of buildings at St John’s raises questions about the efficacy of these devices. It is vital to recognize that mobile phones are essential for emergency communications. A more viable solution could be the introduction of pay phones for inmates, coupled with stricter security protocols to eliminate unauthorized cell phone use. Maintaining family connections for prisoners is important. Furthermore, the relocation of the jail away from the town is long overdue. We ought to concentrate on developing better alternatives and appropriate consequences for rule violations.

Carr Seeks Federal Solutions Address Proliferation Contraband Cell Phones Within Correctional Facilities

ATLANTA, GA – Attorney General Chris Carr is urging the Federal Communications Commission (FCC) to take immediate action to allow for the use of cell phone jamming devices within state prisons and local jails. The FCC currently prohibits the use of cell phone “signal jammer,” and that prohibition extends to state and local governments. Yet in prisons and jails throughout the country, contraband cell phones are being used to plan and orchestrate violent attacks and other criminal activity, posing a real and substantial safety risk to correctional officers, visitors, inmates, and the public at large.

“The easiest way to protect the public from the harms caused by contraband cell phones is to allow for the use of cell phone jamming technology in prisons and jails, but the FCC continues to block our efforts,” said Carr. “This outdated guidance limits legitimate law enforcement tools, presents dangerous conditions for correctional officers, and allows for the escalation of criminal networks both inside and outside prison walls. We’re committed to combatting violent crime wherever it occurs, which is why we continue to call on the federal government to remove this substantial barrier to public safety.”

In Georgia alone, 8,074 contraband cell phones were confiscated in 2023, with 5,482 confiscated to date in 2024. Recently, an incarcerated leader of the infamous street gang, “Yves Saint Laurent Squad,” used a contraband cell phone to order a hit which resulted in the death of an 88-year-old Georgia veteran. A gang leader in North Carolina was able to order the kidnapping of a prosecutor’s father via a cell phone in prison. In California, prison gangs used contraband cell phones to order murders within the prison system and traffic drugs.

“There are hundreds of examples from across the country of how a contraband cell phone in the hands of an inmate can be used as a deadly weapon and gives them the ability to continue their criminal enterprise. We are incensed by the length these individuals go to in continuing those activities and endangering the public,” said Georgia Department of Corrections Commissioner Tyrone Oliver. “As attempts to infiltrate our facilities with contraband cell phones evolve, access to jamming technology is paramount in our efforts to combat those attempts. We appreciate the support of Attorney General Carr in our ongoing commitment to public safety and the safe operations of our facilities.”

In his letter, Carr notes that the FCC policy relies on a statute enacted in the early 1990s, years before prison inmates began using contraband cell phones to plan and engage in unlawful and dangerous activity.

Carr further states: “Nothing in the language of 47 U.S.C § 333 prohibits the FCC from revising its position to allow state agencies to use cell phone jamming devices in prisons. In fact, the United States Bureau of Prisons has recognized the potential value of cell phone jammer already and is permitted to use jamming devices at several federal penitentiaries, including at least one in Georgia.”

In January 2023, Carr joined a 22-state coalition of attorneys general in urging Congressional leaders to pass legislation that would allow states to implement a cell phone jamming system in correctional facilities.

Carr’s Gang Prosecution Unit has also partnered with the Georgia Department of Corrections (GDC) to investigate and prosecute currently incarcerated individuals who are alleged to have engaged in criminal gang activity and discussions regarding the packaging and shipping of contraband items into a GDC facility.

The US Space Force will install 24 satellite jammers capable of disrupting Russian or Chinese communications

July 23, 2024

War. War never changes: thanks to the military-industrial complex, the technology of war will continue to escalate no matter how the world situation changes. Russia is reportedly developing a high-altitude nuclear device that uses electromagnetic pulses to permanently and indiscriminately disrupt enemy communications. Meanwhile, the United States has just announced a weapon with similar purposes but without the chaotic and irreversible consequences.

The US military is installing modular advanced satellite signal jammer capable of disrupting Russian or Chinese communications if necessary. Although the hardware is terrestrial, the US Space Force will oversee the installation and operation. The technology has already completed prototyping. Earlier this year, the military tested the system at two different locations. The Department of Defense has allocated funds to build 24 remote facilities, 11 of which are scheduled to be deployed by the end of the year.

This equipment is not a preventive measure to prevent adversaries from disrupting US communications. Quite the opposite.

"[The terminals] are small, mobile, and low-cost SATCOM portable jammers that can be deployed in austere environments to protect [U.S. forces]," a spokesperson for the U.S. Space Force's Rapid Capabilities Office told Bloomberg. "[The jammer gps will be used] to responsibly counter an adversary's SATCOM capabilities to launch an attack."

"We intentionally designed a small, modular system using commercial off-the-shelf components. This provides the ability to be proliferated, remotely controlled, and relatively relocatable," the Space Force said.

Why it matters:

1. This proves once again that when it comes to electronic warfare involving space assets, no signal is secure.
2. This makes it pretty clear to you that at least China and Russia, and possibly Iran and North Korea, as well as other nations (and some of our allies) have similar capabilities.
3. It should reinforce the idea that if a service is really that important (like PNT), we should have multiple widely available ways to get it, not just through space.

Other things to know:

• Both China and Russia have widely available non-space PNT methods.
