Public WiFi has serious security problems, and the security of the network has been severely attacked by hackers. There have been many cases of using wireless network crimes. In the face of such threats, you may need a WiFi jammer device to protect your information.

Explain the function of GPS jammer and how to use GPS jammer

When buying and using a vehicle mortgage, it is best to configure a GPS jammer within a certain stage. Especially some car dealers who hand over the car and buy the mortgaged car, in other words, once they receive the car, they can turn on the gps signal jammer and put one in the car, and one more in the car trunk! When the shield is turned on, you can be assured of peace of mind during the round trip with the car. However, the jammer cannot be activated 24 hours a day, so after the safety reaches your own chassis, you must find a technical professional to investigate the GPS by yourself, and also modify the GPS positioning equipment and mortise locks, key changes and other security guards to prevent mistakes. just in case.

1. Understand the GPS jammer
GPS jammers (jammers) can reasonably prevent tracking by GPS communication satellites, reasonably affect GPS communication satellite signals, and maintain your track privacy protection and information business secrets.

2. The function of GPS jammer
The GPS signal is the same as the signal on the mobile phone, and it is very susceptible to the influence of electronic components. The signal jammer can shield all the signals in a certain range, so that all the communication devices in the range lose the signal. The installation of a GPS locator on the car enables buyers to easily find their own car on the GPS monitoring management platform. As everyone knows, such a good product is also found by criminals to find loopholes. If you buy a signal blocker on Taobao, Turn on when the car is stolen, there will be no signal in the car, and the car will go offline on the service platform, as if the whereabouts of the car are unknown, you can’t find it anyway.

3. Disadvantages of GPS locator
I have to admit that the GPS jammer also has disadvantages for the user. The signal jammer is only temporarily turned on, and it is unlikely to be turned on all the time. If he turns off the jammer, the GPS locator will have a signal again. Drivers can quickly find the stolen car based on precise positioning information.

gps car signal jammer

In addition to signal jammers, some people will also say that they will use signal detectors to find out and destroy GPS locators. Yes, this is also an objective fact, but this is only valid for some GPS devices. If the GPS tracker is in the dormant state most of the time, the signal detector will not be able to detect it! what happened?

For example, some ultra-long standby GPS locators can only be awakened once a day. After being awakened, the precise positioning information of the vehicle is sent back to the buyer’s network platform and then it enters the dormant state. In the dormant state, it is Without a signal, it is absolutely impossible for car thieves to detect it! In addition, it is also free of wireless network installation. There is no wiring on the surface of the machine and equipment. It can be placed anywhere on the car (if it does not have to be placed in an area blocked by the signal). It is very concealed for engineering safety.

How to use GPS jammer

The GPS jammer can indeed shield GPS signals, but it has disadvantages. It will shield all signals in the car! In other words, a car thief is unlikely to use communication devices such as mobile phones near the car. If he cannot find and destroy the GPS device, he has to always turn on the shield, otherwise, he will eventually expose his behavior. Therefore, how to use GPS jammers must ensure the following:
1. The GPS jammer can be used when picking up the car, so even if there are tricks, there is no need to be afraid.
2. When you return to your own area, you don’t need to shut down, first find an auto repair shop to carry out major demolition. Make sure it is clean and tidy before closing.
3. For safety reasons, a car can continue to use GPS jammers for more than half a year. And to ensure that the GPS jammer can work normally for 24 hours.

Signal jammers to improve concert grade

As for the effect of the concert, many people are now listening to mobile phones, which has led to various interferences. If you listen to music and find that you don’t have a signal cell phone, talk to your administrator and you’ll find a dedicated cell phone signal jamming device here. Several concerts didn’t go well. When an overseas guest arrives, it rings the mobile phone and affects the overall effect of the concert. It gives a bad impression to international friends. Install a cell phone signal jammer to improve the grade of your concert.

4g cell phone jammers for sale

The concert hall is a very independent small space. It has a very elegant atmosphere of music and art. The audience sees the concert and it’s a very good experience. Introduce jammers at this location. Create this new environment. Manage mobile phone signals within a specified time. Providing a feast of music to the viewer. Out-of-service devices can hang up mobile phone calls by emitting jamming radio waves from the mobile phone. If the frequencies are different, it cannot be disturbed. The range of communication suppression effect is limited to a small space.

Many people think that this is because the announcement “Please turn off your mobile phone” came in before the performance started. It is a telephone deterrent device that intentionally makes the radio waves of mobile phones in the area “out of service area”. Prevents mobile phones in the area from communicating with the base station. wifi interference means that it can cover an area of ​​about 50 meters in diameter.

Can anyone other than government officials use jammers?

We know that the mobile phone interference law will interfere with changes in other parts of the world. Some areas are restricted, but some areas are allowed, and some are suspended. Signal jammers will eliminate malicious mobile phone behavior in public places. In India, they installed hardware to protect meetings from interference. In addition, the people of India and China widely use signal jammers to deter school fraudsters. Even in Mexico, churches and hospitals allow the use of signal jammers in Pakistan so that banks and libraries can be used.

portable wifi jammer for sale

In some countries/regions, only the military, prisons, and police are allowed to use cell phone signal jammer.

Signal jammers are considered roadside bombs and GPS tracking and positioning weapons. To protect government officials, signal jammers are used to prevent bomb attacks on mobile phones. As we all know, after President Barack Obama took office, he walked along Pennsylvania Avenue and all phones were blocked-we know that the bomb is controlled by the phone and the controller, but the radar jammer can be stopped. . Signal jammers have also been used in Iraq to stop US military roadside bombs.

The question arises: Why do strict laws on signal interference apply to everyone except government officials? It is believed that not only government officials need equipment, but also many movie theaters, restaurants, and businesses. Some people also want to use signal jammers to do something. In short, equal rights of use in public places, silent and private environments also face the threat of roadside bombs, and installing jammers in theaters and restaurants can take advantage of pure life.

Someone asked: “Only government officials can use mobile phone jammers, who decides?” People also need jammers.

Jammers: High-density objects can block 4G networks and sound alarms

Once they become true secret agents or tools only available to the armed forces, but for those who are not familiar with mobile phone jammer, they know that they are special electronic devices that allow you to jam the frequency of your smartphone.

When sold on the Internet or in specialized stores, the jammer will prohibit the use of GSM, wifi, 3g, 4G and GPS frequencies that we usually use with various TIMs, Wind Tre and Vodafone. Their operation is to send out radio waves that dominate and disturb signals used for phone calls or satellite tracking.

cheap car gps anti tracker jammer

The difference between a cheap jammer and a high quality jammer is the coverage, the power of the noise signal and the number of existing antennas. Once activated, the tool starts to fill the required interference signal frequency with a 180-degree range.

The power of the jammer is expressed in watts or decibels, and the number and type of antennas will affect the coverage and interference range. However, it is precisely because jammers are spreading on the Internet at a price that everyone can obtain, people have tried to prevent this phenomenon by effectively detecting countermeasures for frequency jamming equipment. They are called “anti-jamming devices” and they send alarm inputs when they detect disturbing electromagnetic radiation in the surrounding environment.

Jammer and crime, what binds them?

Jammer and crime, apparently there is nothing that can suggest a link, in reality the two words bind and also a lot!

A person unaware of the facts, reading the technical characteristics of jammers without too much attention, cannot actually understand the use that can ensue if owned by disreputable characters.

We have already dealt with a jammer as a topic, as we have also written about what jammers are for, so the topic that we now lack is “are jammers needed for crime?” The answer comes by itself, and it is affirmative, YES, THEY ARE SO MUCHED THAT THEY GO TO STEAL!

4g cell phone jammer

The first question that arises is, what are they for? Given the multiple uses, it is necessary to create points:

THIEVES USING JAMMERS:

Inhibition of radio and cellular frequencies makes it impossible for the telephone dialer to make the emergency call;
Inhibition of radio and wifi frequencies means that it is not possible to view images and videos from cameras that transmit wirelessly;
Inhibition of GPS, LoJack and GSM frequencies means that your vehicle cannot be located;

ORGANIZED CRIME THAT USES JAMMERS:

Inhibition of cellular frequencies, VHF UHF etc do not allow bugs to transmit, thus making their installation unnecessary;
Inhibition of GPS, LoJack and GSM frequencies is essential not only for car thieves, but also for criminals who want to move without having the problem of the tracker under their car.
Now the second question arises, why do you, like so many others, give anyone the opportunity to buy jammers?

Because we certainly cannot answer for the purpose that the customer will go to, it would be equivalent to condemning a grocery owner for selling a knife that later turned out to be the murder weapon. gsm signal jammer can be used for various beneficial purposes, purposes specified on this page.

Devices that force mobile phones to silence

As cell phone use in public places has soared, making it impossible to endure listening to mid-conversation, a small but growing band of rebels is turning to a slightly drastic solution: the mobile phone jammer, a device which completely cancels the signal transmission of all mobile phones.

GPS cell phone blocker

Jammer technology is not entirely new, jammer exporters from overseas say the demand for jammer devices is increasing every day and they are sending more than 100 a month to the United States – prompting a close scrutiny of the matter by the federal controller and raising the interest of the telephone industries. Consumers include owners of coffee shops and hairdressers, hotels, theater operators, bus drivers and, increasingly, commuters.

The development is igniting a battle for airspace control, within earshot. And the damage will have a side effect. The insensitive chatterers impose their noise on the defenseless who are therefore forced to endure all the noise in silence. While the jammers punish not only the person responsible for the noise, but also the one who talks on the phone in a confidential way.

“If there is one thing that characterizes the 21st century, it is surely our inability to control ourselves for the benefit of others,” said James Katz, director of the Rutgers University Mobile Communications Studies Center. “The one who talks on the phone thinks his rights outweigh those of everyone else around him, while the one who carries the jammer in his pocket thinks his rights are more important.”

Wireless jammer technology works by emitting radio signals so powerful that cell phones are, therefore, canceled and are no longer able to communicate with cell phone towers. The range of action of a jammer varies from a few centimeters to several meters, and the devices cost from $ 50 to several hundred dollars. The larger devices can be left on to create a real off-limit zone for mobile phones.

The use of jammers is deemed illegal on American soil. The radio frequencies used by telephone users are protected, just as are the frequencies used by radio and television broadcasters.

The Federal Communications Commission argues that people who use jammer devices can be fined up to $ 11,000 for just the first offense. The Commission’s enforcement office has sued a handful of American companies, found guilty of supplying the devices – and not only that, but also the one who uses the jammers.

“Investigators from the Commission and Verizon Wireless visited a well-known upscale restaurant in Maryland last year,” says the owner, who refuses to disclose the name, and confesses to buying a jammer for $ 1,000. because he was tired of seeing his employees with their eyes on their phones rather than on customers.

“I told them: put away your phones, put them away, now” but they ignored him.

The owner said that Commission investigators stayed for about a week, looking for jammers using special equipment. But the owner had already turned them off.

The work of the Verizon investigator, as well as that of the Commission, proved fruitless. “Yes he went to anyone in the city and gave them his number, saying to warn him immediately, in case they had difficulty making calls” claimed the owner, who reveals, since that moment, that he has stopped using the jammer.

Unusual. A jammer to prevent phone use in class

Drunk that her students prefer their cellphones to her, Marie (1), a teacher in a Sarthe high school, ordered a jammer on the internet. She has been using her “toy” for over a year and a half.

Just type “cell phone jammer” into a search engine, and the object of the crime appears. Fed up with her students handling the keyboard “under the hood”, she decided to do the same. “I activate it with classes that annoy me, I hide it with a notebook, usually. Cellphones in class are a real problem, and the students have lots of techniques, they hide it behind a bag, a pencil case, in the pockets of a baggy, “she said.

The principle is simple: the signal blocker sends waves which block network reception. “It’s very funny, the students all tend to move closer to the windows, hoping it works better,” Marie jokes.

The use of a wireless jammer in France is punishable by a fine of 450 euros, as only prisons and theaters are allowed to equip them. Marie bought a small one, at the scale of her class, “although it does not work well in the back rows,” she jokes.

The small forbidden box cost him 60 euros, an investment. “My students don’t know I have one, of course, so they try to get their cellphones out anyway, I don’t do that to annoy them a bit and it works,” says the teacher.

Marie has never been grilled by her young people, although some have been suspicious. “It’s weird, it’s only in your room that you don’t get,” dared a group of girls. And in these cases, she feigns innocence: “Look, I don’t know.”

What is a signal jammer and why should it be used in G-20

Mobile phone jammer is device that are often used in political meetings of the size of the G-20, where leaders from around the world are gathered in a relatively small space. In most cases they are the size of a handy, and what they do is very simple: they interfere with mobile phone signals (they emit “noise” in the same tuning), rendering these devices useless.

Why? To avoid two things: on the one hand, eliminate the possibility of somehow taking control of the phone and, for example, activating the phone’s microphone without the user knowing. And it doesn’t have to be President Trump’s – anyone there could serve as a microphone. Signal inhibitors also serve to prevent someone, from a distance, from contacting a cell phone that is in one of the “hot” areas of the G-20, either to give a warning and orchestrate an attack, or to activate a remote bomb.

16 Antennas Signal Jammer

This is how they were used, for example, in Barack Obama’s visit to Argentina in 2016: they were installed along the entire path of the presidential entourage.

Signal blocker is also used for more pedestrian things: in the first game of the Copa Libertadores final, Conmebol evaluated using an inhibitor for Marcelo Gallardo (who could not be on the field of play) to communicate with Matías Biscay . The problem is that the signal inhibitor does not discriminate: anyone who falls within its range (a radius of 50, 80, 100 or more meters, depending on its power, and a cost that goes from 300 dollars onwards) also remains disconnected. They can be the size of a handy, a suitcase or (the most sophisticated) a truck, so the cone of interference moves.

Some Spanish universities put them into practice a few years ago to prevent students from copying or receiving help from outside the classroom during exams. The signal inhibitors have also been used to violate the warning of the alarms that notify the police or the security company via the cellular network, and they have been tested in prisons to have greater control of the exchange of information between prisoners and the people outside.

In Argentina, the National Communications Agency is the only body that can authorize its use, and considers its autonomous application illegal, since it considers that such interference is an illegal use of the spectrum.

Are Cell Phone Jammers the Next Big Thing?

A Philadelphia man was caught red-handed this week for using a mobile phone jammer to prevent fellow passengers on a public transit bus from using their cell phones.

“I guess I take the law into my own hands,” he told an NBC10 reporter about the illegal jammer, “and to be honest, I’m proud of it.”

Teresa Masterson, a writer on NBC10, first encountered the jammer on her morning commute and gave NBC investigators a lead.

A jammer that blocks radio frequencies isn’t just limited to blocking people

But while today’s news and the resulting internet outrage can only be felt by a single man, the practice of jamming cell phones is widespread in both New York and Washington DC. I spoke to two such “jammers” this morning about why they bought equipment that ranged from $ 40 to over $ 10,000 on sites like jammer-welt.com. Some boast a radius of just 15 feet, while others claim they are used in military vehicles and for counter-terrorism maneuvers.

“You’re the best thing ever,” says a New Jersey-to-New York commuter who lugs around a jammer every morning on his 40-minute ride on the New Jersey Transit. He doesn’t do it for the entire trip, he says, only when a fellow passenger speaks “too loudly” or “too long”. “It fits in your pocket – they even make shady packs of cigarettes. I would guess it’s effective for a 15 foot radius, possibly more,” he says.

“When I’ve used it, it’s to turn off a loud speaker on the train that is sitting near me.” He says he bought it online from a website that imports the equipment from China, where it’s legal, and when asked, told me that he never felt guilty about keeping his passengers from talking. “No fault,” he says, “just personal high fives.”

“I always have a grace period for calls,” says another jammer who takes the MARC train to Washington DC. The journey takes about 30 minutes. “If someone says,” Okay, well, I’ll be in the office in 10 minutes, then we can discuss it. “I’m not going to bother you. But if you talk about what you did last night and what kind of curtains you are getting for the house, then yes. Silenced.”

Does he feel guilty? As if it was causing a public grievance? Not as much. “People are mad and ranting on their cell phones all the time. But I feel like it gives me some control over what I believe is becoming an increasingly reckless society.

“I’m not a threat to public safety,” he says. “I don’t put anyone in danger more than anyone else in a subway without the reception of cells being compromised.”

jammer-welt promotes the sensible and legal use of cell phone jammers and correctly protects their legitimate rights and interests.
