Signal Jammer Tech

Blocking remote key communication (lock interference) refers to the act of deliberately interfering with communication when the vehicle's remote key is used to lock the vehicle.

Some malicious individuals and organizations attempt to block the lock by using certain devices and techniques to disrupt the communication between the remote key and the vehicle.

Lock interference techniques include using jamming equipment to interfere with the radio waves of the remote key, and stealing and retransmitting the remote key's signal through a technique called a replay attack.

This means that even if the owner thinks the vehicle is locked, it may not actually be locked correctly.

Lock interference increases the risk of theft

Although high-speed, interference-free wireless LAN standards have become popular, many people still use the 2.4GHz band 802.11g standard wireless LAN (Wi-Fi). This will reduce the situation where you receive radio waves not only from your home, but also from neighboring houses. Wifi jammers have been determined to be emitting powerful broadband radio waves. It continues to interfere with mobile phone signals. I wonder what the radio wave blocking ability is.

The mobile phone suppression device system blocks communication by emitting weak radio waves of the same frequency as the broadcast information radio waves from the mobile base station, and prevents the subsequent display of location registration and polling from being "out of range" and communication. Will be suppressed. The purpose is to provide a GPS jammer that can reliably suppress the communication function of mobile phones and easily meet the standards stipulated by the Japanese Radio Law. This is the interference wave to be suppressed.

Radio jammers, GPS jammers, text blockers and other devices designed to intentionally block, interfere with or disrupt authorized wireless communications. Over the years, I have used mobile phones in movie theaters many times. In the middle of the movie, people's phones rang. If you use a GPS jammer, you don't have to worry about such rude behavior. Just as you as a parent have the ability and right to disconnect the Wi-Fi at home, you should also have the option to cut off the mobile phone signal when necessary.

This means that even if you are tracked or monitored by the car navigation system or GPS logger, you can get away by jamming the GPS. It can be said to be a product with a wide range of applications.

If you think that just because your car is equipped with a GPS system, you can get it back even if it is stolen, it is not the case. Thieves also understand this. They can use GPS jammers to block tracking systems.

Of course, even if it is banned, you can still buy it from online stores. GPS jammers used for vehicle theft can also be purchased online.

The most widely used mobile phone standard is our GSM global system for mobile communications. GSM standard equipment accounts for more than 80% of the current global mobile phone mobile communication equipment market. Although commonly used, you may be most familiar with the use of mobile phones. Yes, calls and text messages rely on GSM to provide stable network data types. But there is much more to the GSM network than we know. Powerful mobile radio uav jammer are one of the guidelines that many electronic manufacturers are familiar with and carefully studied. GSM modules are used in many areas of life, generally used in access control security systems, as well as GSM network car security systems and robots.

GSM also supports indoor coverage. Outdoor antenna power can be distributed to indoor antenna distribution systems through a power divider. This is a typical setup that meets the requirements of high-density calls within the home, and is common in shopping malls and airports. Indoor coverage can also be achieved through wireless signals throughout the building, thereby improving signal quality and reducing interference and echo.

Why do you need a jammer?

GSM is the basic network frequency band for mobile voice communications and SMS services. As we all know, improper use of mobile phones is a serious phenomenon, and using mobile phones in public places will bring a lot of noise to others. When you are reading or relaxing quietly, someone suddenly calls loudly to disturb you? I think so. When we need quiet, we don't want to be disturbed.

The GSM network band is very important for the use of electronic devices. Therefore, in many places where mobile phones are prohibited, jammers are installed to interfere with the basic communication of mobile phones. This is also called GSM interference.

Buying a GSM jammer requires shielding signal types, such as whether you need to shield 3G and 4G network bands in addition to the GSM network. In this way, you can buy a mobile phone jammer, which will block all mobile phone signals. In addition, since you have purchased an electronic jammer, you need to consider where to use it. Portable jammers are convenient for indoor and outdoor use, while desktop jammers use a multi-antenna design. As the name suggests, not only personal use will be more extensive, but also large places such as prisons and courts will use it, with a wider interference range and more types of signal shielding.

I personally recommend an 8-antenna portable GSM jammer to meet your needs. It is enough to provide a quiet reading environment when you need quiet. For enterprises and important institutions, a powerful multi-antenna desktop jammer would be your better choice. This is important in terms of functionality and interference radius, and is sufficient for large-scale applications.

During a search related to a suspected burglary, Vanderbilt police officers detected signal jammers.

Sheriff Robinson emphasized that the device was designed to turn off Wi-Fi cameras, ring doorbells, and security systems utilizing radio-based sensors. The only conceivable reason for owning such a device, according to the sheriff, is for engaging in nefarious activities and unlawful behavior.

It has been confirmed by authorities that there is no law against possessing a signal jammers, but utilizing it is considered a federal crime.

Sheriff Robinson indicated that the next action to take is to have discussions with lawmakers. He pointed out that Indiana currently lacks a statute specifically addressing interference with communications, a gap that he believes should be addressed. Robinson stated his intention to collaborate with state legislators to address this loophole.

It has been confirmed by the sheriff's office that the source of the issue lies in an alleged daytime burglary that took place in the Cambridge Village neighborhood.

Two individuals are suspected of using advanced technology to target a home.

According to reports from deputies, a couple returned home on Sunday to find two strange men inside.

The authorities have confirmed that both suspects absconded in a gray Jeep, fleeing from the location.

The deputies' timely presence at the scene led to the arrest, with credit given to a FLOCK camera obtained by Cambridge Village through the sheriff’s office.

Vanderburgh County Sheriff’s deputies, acting on a report of burglary, intercepted Jaime Riveras, a citizen of Chile, on Highway 41.

It was conveyed by Sheriff Robinson that Riveras indicated he did not stop in Evansville en route to Florida from St. Louis.

Sheriff Noah Robinson declared that, in addition to eyewitness accounts, a search warrant was secured for all items in the vehicle. This led to the discovery of two cellphones, which revealed GPS data points indicating that the suspect's vehicle was at the Riveras' residence during the burglary.

Riveras is accused of several charges, one of them being interference with the reporting of a crime for allegedly using a GPS blockers.

How to choose a 4G jammer for your local network?

1. What is the difference between 4G and 4G LTE?



4G LET (3.9G) is not a real 4G network! 4G LTE was proposed by the 3gpp organization in response to the emergence of WiMAX. The latest LTE-Advanced released by 3gpp is the full name of 4G technology.



2. What is the difference between WiMAX and LTE?

1) The WiMAX standard is set by IEEE, and the LTE standard is set by 3GPP. The above two points have different basic protocols, but it is said that smooth interoperability will be achieved over time.

2) The goal of WiMAX is to achieve broadband mobility, and its predecessor is WLAN (WiMAX has an advantage in speed and a disadvantage in mobility). The goal of LTE is to achieve broadband mobile communications, and its predecessors are GSM\WCDMA\HSPA (LTE has an advantage in mobility and a disadvantage in speed).

The final rate results are similar!

• In the current design specifications, WiMAX is not yet compatible with LTE, but LTE is compatible with WiMAX.


• In many countries, LTE, WiMAX, HSPA+, 3G UMTS, GSM networks coexist!

We customize the jammer signal according to the customer's local frequency, other shops send the same jammers all over the world with poor shielding effect!!

Proliferation of wireless signal jammers

The reliance of our society on wireless technology is growing rapidly, shaping the way we live our lives. From making phone calls on the go to using GPS for directions, wireless devices have become indispensable. Nonetheless, this dependence also exposes us to the risk of best signal jammer.

How does a signal jammer work?

In general, jammers simply disrupt existing wireless signals by flooding them with noise. By adjusting the jammer to a specific target frequency range and emitting a high-power noise, tone, or pulse, the jammer can interfere with nearby receivers trying to listen for that frequency. Traditionally, this has meant interfering with radio communications, but the same core principles apply to other types of wireless signals - cellular, WiFi, Bluetooth, GPS, and so on. Jammer ranges vary depending on the power and size of the device; In urban environments, small handheld jammers may be effective at a range of 100 meters or less, while large military-grade jammers can be installed in locations that easily cover hundreds of miles of open terrain.

Military and paramilitary uses of signal jammers

The widespread use of jammers occurred during World War II, as the Nazis disrupted Allied radio transmissions in occupied Europe. Subsequently, their popularity continued to rise during the Cold War. The Soviet Union and China employed jamming techniques to interfere with incoming signals, Cuba blocked American radio stations, and both North and South Korea engaged in jamming each other's transmissions.

The use of signal jammers remains prevalent in electronic warfare (EW), particularly within the Russian military. In 2018, Russia reportedly utilized this technology to interfere with U.S. low-altitude surveillance drones during the Syrian conflict, prompting questions about whether the drones crashed or were merely redirected.

Among Mexican drug cartels, jammers have risen in prominence as a favored tool, often paired with drones as part of their technological arsenal.

Small commercial drones have been deployed to monitor territories, particularly during nighttime using thermal cameras. These drones have also been weaponized to drop explosives on targets, a tactic previously employed by terrorist groups like the Islamic State in the Middle East. As a result, cartel members carry portable signal jammers to interfere with nearby drone connections, as well as cellular and radio communications.

The notion that signal jammers should not be a worry for someone like me, who is not a high-value military target or associated with a warring drug cartel, is mistaken. It is crucial to acknowledge that anti drone jammer are easily accessible online, inexpensive, and can be utilized by individuals who know where to find them. These devices can significantly affect various aspects of your daily routine. Facebook has even shared unexpected demonstrations to showcase the consequences of signal jammers.

Our intention is not to compel you to cease using WiFi, discard your phone, or dispose of your ham radio - wireless devices are convenient and highly beneficial during emergencies. Nevertheless, for the security of your family and property, it is advisable to consider their potential vulnerabilities and take measures to limit reliance on wireless devices.

• Prevent industrial espionage using mobile devices as eavesdropping devices or for taking photos (cameras)


• Counter terrorist threats, such as remotely detonating bombs in high-risk areas


• Eliminate public nuisance in places such as cinemas, restaurants and churches

How cell phone blockers work

Cell phones are two-way radios that communicate via cell towers. cell phone jammer work by sending a strong signal on the same frequency used by mobile devices to effectively interfere with communication between the device and the cell tower. The result is that the mobile device does not work and "No network" is displayed.

Physical description of cellular jammer

It comes in different sizes and shapes. Some are pocket sized, some are bigger. Some masquerade as plain phones or briefcases.

Precautions before buying a mobile phone jammer:

• What is the effective interference range (10-50 meters above)

Which cellular systems can it block (cdma in North America, gsm, tdma, 4G, 3G amplifiers, pcs, dcs or all?)

• How many cellular systems can it block simultaneously (cdma, etc...) (Low-end models can only block one type at a time, while more complex models block multiple systems at once)

Teacher suspended for blocking students' cellphones

LAND O' LAKES, Fla. --The act of a science teacher in Florida using a signal jammers to prevent his students from using their cellphones during class has resulted in his suspension.

WTSP-TV, the CBS Tampa affiliate, highlighted Dean Liptak's efforts to engage students in their lessons by diverting their attention away from their phones.

Liptak's five-day, unpaid suspension was officially sanctioned by the school board members in Pasco County on Tuesday. Liptak did not raise any objections to the decision.

According to officials, Liptak utilized the phone jammer in his Fivay High School classroom, commencing on March 31 and concluding on April 2.

In his conversation with the school district investigator, he made it clear that he had no intention of causing any disruptions. He explained that he believed the jammers were permissible as long as they were not intended for any malicious purposes.

According to WTSP, the district has acknowledged that Verizon made the choice not to pursue charges against him.

Superintendent Kurt Browning conveyed his concerns in a reprimand letter, pointing out that Liptak's actions of signal jamming had the potential to violate federal law and create interference for individuals attempting to contact 911 during emergencies.

"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.

It has been stated by Cobbe that Liptak's jamming device effectively hindered communication to the cell tower situated on the Fivay High campus.

It is high time that steering wheels were equipped with cellphone signal jammers.

In California and a minimum of twelve other states, it is considered unlawful to operate a vehicle while holding a cellphone. Despite the clear prohibition, many individuals still choose to disregard this law.

Without fail, we encounter thoughtless and self-entitled individuals on a daily basis, who pose a danger to themselves and others by engaging in conversations or texting while driving.

In motor vehicle accidents last year, a staggering 37,133 fatalities were recorded by the National Highway Traffic Safety Administration, with distracted drivers accounting for more than 3,000 of these deaths. Moreover, each year, a significant number of individuals sustain injuries due to drivers being distracted and not paying attention to the road.

In order to gauge the perspective of car manufacturers, I reached out to the Alliance of Automobile Manufacturers, an industry association. According to Bryan Goodman, a representative of the organization, automakers approach this issue with great 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.”

The statistics speak for themselves: distracted driving fatalities exceed the number of lives lost in the Sept. 11 terrorist attacks, underscoring the urgent need to address this grave public-safety concern.

The rise of the Internet of Things has led to an increasing demand for location services. According to certain institutions, it is predicted that 60% of Internet of Things devices will rely on geographical location data. Outdoor positioning, in particular, is expected to be a significant market that should not be overlooked.

The GNSS (Global Navigation Satellite System) is a highly esteemed international club comprising of merely four members, which garners the interest of global leaders and the scrutiny of numerous esteemed scientists and engineers. These four members include the GPS of the United States, GALILEO Galileo of Europe, GLONASS of Russia, and Beidou COMPASS of China.

There are four prominent satellite navigation systems worldwide, including China's Beidou satellite navigation system, the United States Global Positioning System (GPS), the European Union's Galileo satellite system (GALILEO), and Russia's GLONASS satellite system (GLONASS). These four systems are acknowledged as suppliers by the United Nations Satellite Navigation Committee.

China Beidou is a recent addition, yet it stands out as the most dynamic member in terms of development. What exactly is Beidou and how does it influence our daily lives? This intriguing subject has garnered significant attention. Numerous scholarly publications delve into the intricacies of Beidou; however, these professional articles often employ jargon that may deter the interest of the general public.

Small GPS signal blockers great use

The GPS satellite positioning system is the most widely used satellite positioning system globally. It enables vehicle tracking, route navigation, information inquiry, traffic command, emergency assistance, and various other functionalities. While the GPS satellite positioning system has brought immense convenience to our lives, it has also given rise to certain challenges that pose a potential risk to personal safety.

For instance, when dealing with mortgage car companies, the original owner of the car temporarily relinquishes control of the vehicle in exchange for monetary assistance. To prevent any unauthorized retrieval of the car by the original owner, these companies opt to purchase GPS shields. These shields are then installed in the vehicle's parking lot and on the car, making it impossible for the original owner to track the vehicle. This measure effectively safeguards the property's security.

The market for GPS locators is witnessing significant growth, leading to a surge in demand for GPS signal blockers. These blockers are sought after by individuals who desire to evade GPS signal tracking. Nevertheless, it is essential to evaluate the actual effectiveness of GPS signal blockers in shielding signal tracking.

Most GPS locators can be effectively shielded by
gps blocker. The use of blockers disrupts the normal functioning of the GPS locator, preventing complete data transmission to the locator monitoring platform. Similar to mobile phones, GPS locators require the insertion of a mobile phone card or an Internet of Things card to retrieve data. Therefore, as long as the GPS signal blocker can obstruct the signal transmission of the mobile phone card, it can also block the GPS locator.

Why use cell phone jammers?

What should I consider when choosing the right model?

Admit that sitting on the bus listening to someone talking loudly about a problem on the phone is pretty boring.

It's even worse if it happens in the middle of an important meeting, or even during a fancy dinner at a restaurant. These are the most common reasons people buy different phone jammers.

There's only one thing you need to be aware of! If you're not sure how to choose the right type of signal blocker, then you'd better read the following information.

Your budget

The first thing you need to do is determine your budget. It's important to set the number and start searching for the devices in it.

Once you find a wifi blocker that suits your needs, you should start looking at reviews about it. Since the Internet is a great place, you can be sure that there are many people who have the same equipment and can share their experiences with you.

On our website, you will be dazzled by the choice between different quality models and the number of antennas (from 1 to 12).

Broadcast frequency

Keep in mind that different devices (such as GSM wireless alarms) operate on different frequencies. This is why one of the most important things is to understand the broadcast frequencies of mobile operators.

Support frequency

Once you have found the broadcast frequency, you can go to the next step to see what frequencies your device supports. If the product you search for is supported, then you can buy it.

Cell Phones: Buying a Jammer - You Have to Consider This

Jammers interrupt mobile device wireless connections such as WiFi and GPS. You can read what it's for and what to consider when buying one here.

What can cell phone jammers be used for?

cell phone jammer, also known as cell phone blockers or jammers, are devices that disrupt radio connections such as cell phone networks, WLAN or GPS by emitting radio waves. The range is between 10 and 40 meters.

The military and government even have models that can jam radio signals for miles.

Retailers can use gps blocker to prevent you from comparing prices in-store. Thus, retailers can increase sales.

Jammers are also useful in certain rooms where silence or distraction is desired. This prevents the phone from ringing while watching a movie or while young people are chatting at school.

But criminals can also use gsm jammer to disrupt wireless alarm systems and other radio communications, and prevent emergency calls from being made over cellphone networks.

Are cell phone jammers allowed?

The use and trade of such mobile phone blockers is prohibited within the European Union. Use may be fined up to 1000 EUR. Penalties could be higher if emergency calls are blocked buy jammers. In some European countries, jammers are approved by the authorities. Such equipment is occasionally used in French cinemas and theaters. But in Germany, this is strictly regulated: whoever wants to use radio frequencies needs to be assigned according to the Telecommunications Act. Even the import of such equipment is prohibited and strictly controlled. The devices are then confiscated and hefty fines imposed.

Use of mobile phone jammers

School cell phone jammer

The questions on the exam are well known. Use of unauthorized assistive devices such as cell phones, smartphones, tablets, wearables, or similar devices during an exam will be considered attempted cheating.

For some time now, auditors have increasingly observed remediation through the use of so-called cell phone jammers.

Products now available range from pure "cell phone indicators" to active jammers to smart IMSI catchers that force replacement of new GSM cells and log personal data in wireless network areas.

The Ministry of Education of Baden-Württemberg has issued a statement in this regard, clearly regulating the use of such devices:

From the Ministry of Culture's point of view, the use of devices that completely block reception by mobile phones by emitting their own radio waves ("blockers") is legally unacceptable, regardless of data protection checks. Because in the GSM frequency range only mobile network operators have the right to use the frequencies they auction and therefore also have the right to operate cell phone blockers.

The operation of mobile phone interceptors by third parties is an unallocated frequency use, which is prohibited according to Art. 149 (1) Art. 10 TKG. The use of mobile phone interceptors does not require a frequency assignment only if "the authorities exercise their legal authority in accordance with the conditions of use of the frequencies laid down by the Federal Network Agency". There is not sufficient legal basis for use in a school setting.

It is also illegal to use equipment that listens to or records messages and is punishable by breach of telecommunications secrecy.

From the perspective of the Ministry of Education, the use of a device that scans a specific frequency range and only shows that there are switched on phones in the room without identifying the exact location is permitted under data protection law, as no personal data has been processed.

The question, however, is whether it is wise or useful to use such a device, and therefore necessary. Carrying a mobile phone is already considered cheating in public school exams in Baden-Württemberg due to the special regulations that apply. Since the effects of such devices are easily circumvented, for example by placing a mobile phone in airplane mode, scanners are of no use in exam situations. In this case, the device would not be detected by the frequency meter; but would still be carried illegally, thus constituting a fraudulent act.
