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


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


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


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


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


3G 4G Cell Phone Jammer

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


Police band


EMS Band (Emergency Medical Services)


Fire band


Cellular jammers can prevent teenagers from negligent driving


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


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


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


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

A resident of Rogers Park named Dennis Nicholl, aged 63, has been charged with deliberately interfering with cellphone signals during his Red Line commute. His motive was to create a quieter atmosphere for himself. In order to address this issue, Nicholl will be undergoing counseling and is likely to avoid facing criminal penalties.


Users of the Reddit website have given the nickname "The Red Line cell phone jammer" to Nicholl, who has now agreed to a deferred sentence on misdemeanor charges. These charges were filed against him for using an illegal device to block cellphone signals on the L train. Charles Lauer, Nicholl's attorney, has stated that the upcoming court appearance in June may result in the dismissal of the pending misdemeanor count.


With one of his lawyers by his side, Nicholl briskly departed from the courthouse, opting not to provide any answers to the queries of reporters.


Blocker CDMA GSM 3G 4G

"He's scared out of his mind that this happened," Lauer said outside the courthouse. "He's turned in that (jamming) device. I don't think we're going to hear from Mr. Nicholl about this again."


Photographs of Nicholl employing an illicitly obtained miniature signal disruptor from a Chinese manufacturer had been making rounds on the Internet before receiving a tip about Nicholl from CTA officials. A coordinated sting operation involving the CTA, Chicago Police, and the Federal Communications Commission was launched in early March, leading to Nicholl's arrest for activating the signal jammer while an undercover officer was using his cellphone in Nicholl's car on the Red Line.


After being apprehended on a Red Line train on March 7, Nicholl spent a night in jail before his bail hearing. Initially charged with a felony for interfering with a public utility, the charge was subsequently downgraded to a misdemeanor earlier this month.


Lauer stated that Nicholl had been caught interfering with signals on the L line before, but he did not face any serious consequences and received much less media attention than he did during his recent arrest. The unassuming accountant, who was just looking for some peace and quiet on the L, has since experienced difficulties at work, according to Lauer.


According to Lauer, his only wish is to escape and conceal himself.


He understood that it was unlawful, but he didn't view it as a significant violation. It was more comparable to getting a ticket for a traffic violation.


Let's hope he doesn't get upset if others bother him.

Many used car dealers often install long-term GPS tracking systems, the purpose is self-evident. Therefore, signal jammers and signal detectors become popular equipment.


GPS signal jammer are small, high-power radio frequency (RF) transmitters that interfere with legitimate communication devices (cell phones, GPS, Wi-Fi networks, and toll readers).


It emits radio frequency signals at the same frequency as GPS signals, causing interference and preventing GPS devices from receiving accurate signals. This interference can cause GPS devices to lose their connection to GPS satellites, making it impossible to track their position or receive accurate location information. gps jammer are illegal in many countries, including the United States, because they can disrupt the operation of emergency services and other vital systems that rely on GPS signals. Using GPS jammers can also be dangerous and can lead to accidents, especially in industries such as aviation and navigation.


GPS receivers rely on low-power microwave signals broadcast by GPS satellites. GPS signal jammers work by overwhelming these satellite signals with radio signals of higher power but shorter range, creating "noise" that causes the GPS receiver to be unable to accurately calculate its position.


GPS jammers are small, portable and easy to operate. Anyone who wants to disrupt the operation of GPS devices or systems can buy them online and use them.


What does a GPS jammer look like?


Because the devices that can block GPS come from a number of manufacturers, they vary widely in shape, size and dimensions, making them difficult to spot inside a driver's vehicle. Most commonly, GPS interceptors operate over short distances and are small enough to plug into a power source such as a cigarette lighter or iPhone and intercept signals from GPS trackers installed in the cockpit of a vehicle.


Some GPS jammers look like small black boxes or cylindrical devices with antennas, while others are designed to look like everyday items like cell phone chargers or USB drives.


Handheld GPS jammers are usually small and easy to carry. They usually have a small built-in battery that is used to interfere with GPS signals from nearby devices. Larger GPS jammers are typically used on vehicles, boats, or buildings and are designed to cover a larger area or distance.


Cigarette lighter GPS jammer structure


Making a DIY GPS jammer for your car tracker is not an easy task, as it requires a deep understanding of the fundamentals. However, if you are determined to build one, you can disassemble a simple GPS jammer as a reference.


The weakness of GPS signals makes it easy for low-cost jammers to jam them. These jammers do not attempt to mimic GPS satellites, but transmit loud enough noise to drown out the real signal. As a result, legitimate satellite signals become undetectable. When the jammer is activated, the effect on the already weak signal is obvious, as the mode of the device broadcast completely overrides the signal


Now, the only thing to do is to examine its internal components and understand its functionality. Given the low price, it's still amazing to see how something so cheap can cause such significant damage.

On one side of the PCB, we can only identify two key components, the 78M05 regulator that reduces the vehicle's 12-volt power supply to 5 volts, and the infamous NE555 timer known to hackers. Unfortunately, it took the removal of illegal jammers to finally discover one of the most iconic integrated circuits in the history of electronics, but that's the reality.


Radio frequency in vessel


There is no doubt that the component labeled 13BA A041 is the main attraction. So, what is it? Although I was unable to find a datasheet for that particular model, it has been identified as a microwave voltage controlled oscillator (VCO). The metal top we see is actually a shielding material, and with some effort we can examine the surprising array of components crammed into the tiny space of 9mm x 7mm.


gpsjammer diy

The basic working principle of the device is that the control pin of the VCO (identified as VC on the screen) is linked to the output of the 555 timer on the other side of the board. The signal of the 555 timer modulates the output of the VCO, which causes us to observe noise centered on the 1,575 MHz GPS frequency.


By connecting the oscilloscope to the VC pin, we can see the 133 KHz sawtooth signal produced by the 555 timer. Adjusting this signal could change the frequency range in which the jammer operates, but the extent of this possibility is unclear without a VCO data sheet. Since these components are likely to be the cheapest, it is reasonable to assume that the limitations may not be too great.


In addition, it is necessary to study the small four-pin device designated Q6 at the top of the board. When the high frequency signal is passed from the VCO to the center pin of the antenna connector, it is placed directly in the path of the high frequency signal, so it makes sense to use it as an amplifier. However, it can also be used as a diode to protect electronics from anything that might be picked up from the antenna.



What are the frequencies of all GPS signals?


GPS signal frequency band:


GPS L1:1570-1580MHz


GPS L2:1227.60 MHz


GPS L3:1381.05MHz


GPS L4:1379.913 MHz


GPS L5:1176.45MHz


Usually, the civilian frequency band only needs to block GPS L1 L2. Most devices only use GPS L1.

Presently, we are in the process of renting a home. The neighborhood tends to get noisy in the late evening, extending past midnight, as our neighbors enjoy playing loud music.


The act of reaching out to the police proves futile in resolving the situation. Despite my numerous attempts to seek their aid, their promises to dispatch help go unfulfilled. Consequently, I initiated a quest to investigate signal blockers, focusing solely on wifi signals rather than cellular ones. Fortunately, I came across a device that seems to be a suitable solution.


At first, I was doubtful about how they handle payments. Nevertheless, I soon discovered that their product was exactly what I had been searching for.


I settled the payment and waited calmly. The standard shipping specifies a delivery window of 7 to 15 days.


Following the completion of 15 days, we obtained the tracking information. At that point, it cleared the port and was handed over to DHL for transportation. Within a mere 2 days, the package successfully reached its intended location.


Upon unpacking, I affixed the antennas and established the connection with the charger. It was then that I realized the battery had reached its maximum capacity.


The most popular 8 band jammers

We patiently endured a few days until the incessant music disrupted our peace. Taking matters into my own hands, I retrieved the device from the nightstand and activated it. It is important to note that these neighbors reside a few houses away from us. To my surprise, the music abruptly stopped after a few seconds. Subsequently, I overheard people discussing the cause of the disturbance. In order to investigate further, I left it playing for a solid 20 minutes. Eventually, I switched it off and retired to bed.


The initial charging of the jammer device resulted in a loud bang and smoke emerging from it, causing irreparable damage. Following communication with the company, I was issued an RMA return number and advised to send the device to China for repair or replacement. The return shipping required an extra $25 fee, on top of the original cost of more than $350. It took a considerable amount of time to receive the restored radio signal jammer.


Certainly, the cell phone signal jammer is a valid establishment, as per your question. It appears that certain reviews are unreliable. I can substantiate this with evidence.

You might be familiar with cell phone jammers, which have the ability to block incoming and outgoing calls, text messages, and data transfers.


This blog will answer various questions about signal jammers


Are cell phone jammers legal?


The sale, advertisement, distribution, or operation of mobile jammers is against the law in the United States and numerous other nations.


According to the Federal Communications Commission (FCC), any form of radio communications jamming device that intentionally interferes with "authorized radio communications" is considered to be a grave hazard to critical public safety communications. This interference may hinder your ability, as well as others', to make emergency calls such as 9-1-1, and it can also disrupt the communication channels of law enforcement agencies.


Radio frequencies are not only protected by the Communications Act of 1934 to ensure public safety but also to prohibit any interference with authorized radio broadcasts.


How do cell phone jammers work?


Devices known as cell phone signal jammers, cell phone blockers, signal disruptors, GPS jammers, or text blockers are designed to block cellular connectivity in a targeted location.


By transmitting signals on the same radio frequencies as cell phones, interfering devices effectively block the functioning of mobile devices. This malicious act, referred to as a "denial of service attack," renders mobile devices useless when they come within the range of these interfering devices.


Jammers with limited sophistication aim to obstruct phone signals by jamming a singular frequency. This method often deceives mobile devices into perceiving a lack of signal, leading to their inability to function.


Why use a cell phone signal jammer?


Advocates for such technology assert that signal jammer devices are indispensable in environments where people find it challenging to comply with established cell phone etiquette norms. This includes places like schools, theaters, vehicles, or tranquil train rides, where activities such as talking, texting, streaming, and so on, could be seen as disruptive or even perilous.


It is crucial to keep in mind that signal blocker device have the capability to obstruct not just phone calls and text messages, but also GPS, WiFi, and potentially the functioning of police radar. This is precisely why the sale, promotion, and utilization of cell phone jammers are strictly prohibited by the federal government in the United States, as stated earlier.



Will a cell phone signal jammer block a cell phone signal booster?


Sadly, the interference caused by signal jammers can indeed affect the performance of your signal booster.


The primary function of signal boosters is to amplify existing signals. Nonetheless, if a jammer blocks the signal, the booster will be unable to fulfill its purpose.

A cosmetology school located near Dallas has found a use for a 5W adjustable cell phone blocker - creating a peaceful environment in the classrooms. The decision to install this jamming device, along with three others waiting to be set up, was just one step in a series of actions that unfolded last week.



Phonejammer.com, a London-based company, has been under the FCC's observation for quite some time. In 2008, the agency issued a citation to Phonejammer (PDF) for their involvement in marketing radio frequency devices intended to intentionally interfere with cellular and PCS frequencies in the United States.


The company denied marketing these products in the US, where they are illegal, but FCC staff observed that the signal blocker were priced in US currency, the default shipping location was set to the United States, and the site featured testimonials from US citizens who had purchased phone jammers from Phonejammer. Additionally, the jammers on the site were designed to target US cellular and PCS frequencies.



It is possible to have concerns about the federal government's involvement in your business operations, which may prompt you to consider making changes. However, this does not apply to Phonejammer. On November 9, 2009, the Federal Communications Commission (FCC) received a complaint, presumably from AT&T, regarding cellular interference in the 800MHz and 1900MHz frequency bands. The FCC's Texas field office staff investigated the issue and traced it back to the Cosmetology Career Center in Carrollton, Texas. They discovered a 5W jammer on the premises (PDF).


Phonejammer's legal representative informed the FCC earlier this year that the company has not sent out or distributed any units to the United States.


The 5W jammer offered by the Cosmetology Career Center is currently priced at $395. Equipped with two antennas, it boasts a jamming radius of 2-25m and effectively blocks PCS, GSM, and CDMA signals ranging from 850MHz to 2100MHz. According to the website, its "operating location" is specified as South America and Africa.


It is interesting to note that in Texas and Florida, individuals are allowed to openly carry firearms into a Starbucks, while the same does not apply to phone jammers. Therefore, when a cell phone disrupts the peace at a nearby table and the owner loudly answers the call, the only recourse is to either ignore the disturbance or resort to using a firearm. This situation raises concerns about the effectiveness of current public policy regulations.

Modern life essentially requires us to give up data and privacy for everyday activities, from social media use to airport travel (i.e. biometric-based services like Clear and TSA Precheck). These practices extend to our vehicles and, in some cases, our private conversations. As the risk of hacks and data breaches continues, many people are looking for ways to not only reduce data breaches, but also protect themselves from harmful exposures.


Some of the most tempting and easiest ways to go off the grid include GPS jammers and audio or voice protection systems, sometimes called voice cell phone jammer. When you consider these different counter-surveillance devices, it is important to recognize their differences, especially when it comes to legality. gps jammer are illegal devices, while audio jammers are legal and ethical, but their names are inaccurate because they serve completely different functions than their highly illegal counterparts.



GPS Jammer:


GPS jammers were originally designed for government use to hide the location of combat vehicles during high-risk missions. Essentially, a GPS jammer is a small device used to hide your whereabouts from GPS tracking devices that are monitoring your location and activities. GPS jammers emit radio signals on the same frequency as the GPS device, and due to the interference, the GPS tracker cannot determine the location of your vehicle.


They're cheap, easy to conceal, and offer instant protection - GPS jammers seem like a no-brainer. However, their use is prohibited by law, and they can actually be dangerous.


Audio Jammer:


Audio jammers serve a similar purpose to GPS jammers, but in a different way. They are small devices that produce a unique sound to protect confidential conversations from external listening devices. Randomly masking sounds desensitizes microphones in that area, essentially rendering them useless. This extends to many types of microphones and eavesdropping devices, including voice recorders, radio frequency transmitters, hardwired microphones and shotgun microphones. The main goal is to ensure that private conversations remain private, even if the eavesdropper is only a few feet away.

A number of online retailers and drone technology companies are advertising RF jammers as tools to deter drones or protect privacy, sidestepping federal laws that forbid the sale of such devices in the United States.


Rf signal jamming device are devices that interfere with communication systems, usually by sending competing radio signals to confuse nearby electronics. It's a decades-old technology that federal regulators have been trying to crack down on, but interest in jammers persists because people can use them to avoid unwanted drones, disable security cameras or block Wi-Fi networks.


Many consumers are uninterested primarily because of the cost involved. Large corporations and state government agencies are closely following the escalation of drone warfare in Ukraine and Israel, and are making preparations for potential domestic drone terrorism.


Could this happen in your backyard? That's a real concern for a lot of people


A significant number of individuals are eager to adopt this technology, although there are also those who are apprehensive about its use due to the possibility of disrupting controlled airspace.


The applications of jamming devices are diverse, ranging from causing confusion among unwanted drones to disrupting Wi-Fi networks and deactivating doorbell cameras. Within a Reddit community dedicated to Ring doorbell cameras, some members raised issues about the misuse of jammers to interfere with the cameras during theft activities for avoiding detection. One Reddit user highlighted the paradoxical situation where Amazon seems to profit from both ends: Ring falls under Amazon's umbrella, and Amazon serves as a marketplace for acquiring devices that could potentially disable Ring's cameras.


Amazon remained silent on inquiries regarding their impact on Ring devices.


Jammers, also known as RF "blocking," are a commonly discussed subject on online forums that cater to individuals who hold the belief that they are being specifically targeted for extensive surveillance by the government or other entities. This belief or phenomenon is occasionally referred to as "gang stalking."



The concept of jammers, or RF "blocking," is frequently debated on online forums that cater to individuals who hold the belief that they are being singled out for in-depth surveillance by the government or other entities. This belief or phenomenon is sometimes referred to as "gang stalking."


Potential markets for anti-drone blocker, such as RF jammers, consist of large companies and organizations that have concerns about drone terrorism but are prohibited by law from using jammers. In a letter addressed to congressional leaders last year, four major sports leagues, including the National Football League, requested Congress to authorize state and local law enforcement to utilize anti-drone capabilities.


In several states, prison officials have voiced their need for legal authorization to utilize jammers as a means to obstruct inmates from utilizing cell phones.


Nevertheless, the current legal framework restricts the acquisition and utilization of RF jammers to a select few government entities, namely the FBI, the Department of Homeland Security, and the Departments of Energy and Defense.


Corporations that specialize in drone countermeasures primarily cater to overseas clients.



On its website, IXI Electronic Warfare, a company specializing in drone defense, highlights the potential dangers that drones can present to stadiums, prisons, and airports. They claim to possess the capability to swiftly eliminate these threats, utilizing radio-frequency jammers known as Dronekillers. Nevertheless, it is crucial to acknowledge that stadium operators, prison authorities, and airport officials in the United States are not legally permitted to purchase such products.





In an email, the California-based company emphasized that their primary focus lies in overseas operations, citing the comparatively lenient regulations in those regions. They further clarified that their sales services are available solely to authorized federal agencies within the United States.


The spread of such devices in the United States has caused worry among certain experts in counter-drone countermeasures.
