About the need to use interfering devices in public places

Many people don’t think installing cell phone jammer in schools is a solution, but because children have access to the internet in several other places, such as at home or in open Wi-Fi areas in the city. It’s a very good plan. Adolescents do not have enough maturity to use the Internet properly. From time to time, out of curiosity or under pressure from peers, they may come into contact with content they shouldn’t have. Even if someone accidentally makes such a mistake, it is a very good idea to install jamming devices.

Apart from basketball, what makes me more happy than sports is being able to watch movies in the theater. This is a rare hour and a half for me to get away from the real world and immerse myself in the fantasy of others. Using a mobile phone in the theater is distracting. Like a drunken fan of sports games, it’s distracting. If you look carefully, a nearby ringing phone suddenly interrupts your thoughts, which is terrible.

If you’re attending an emergency meeting and don’t want to join unwanted calls or messages during an important meeting, you can take advantage of mobile phone signal interference technology. Using 3G / 4G Phone Jammer, this technology allows people to avoid calls and text messages without turning off the phone. When this technology is enabled, the signal from the base station will be blocked directly and you will not be able to communicate with others via your mobile phone.

I heard that some devices can prevent eavesdropping and this is true

There are equipment to prevent eavesdropping

More precisely, this is a technique called “scrambling”, namely jammers and jammers. With the popularity of mobile phones, this interference has become popular among the public.

Interference is a device that interferes with radio waves used in communication devices such as mobile phones. When this kind of interference occurs, it interferes with radio waves emitted by mobile phones at a certain distance from the device.

Places that are susceptible to interference include concert halls, movie theaters and hospitals where the use of mobile phones is restricted.

Recently, signal jammer has been installed around bank ATM machines, which are often used to prevent transfer fraud. Many people may be familiar with this news.

Moreover, this interference is an effective preventive measure to prevent the use of radio waves for eavesdropping.

Interference can also prevent eavesdropping

You can use scrambling to block listening. Several scramblers are commercially available and can be purchased by the public.

Jammers can be divided into two types.

Types of blocking/blocking radio waves

Types of hard to hear

There are two types of phone scramblers: one that blocks radio waves and causes interference, and one that makes speech difficult to understand. You can use any of them to stop eavesdropping.

You can use a single encryption machine the same size as the apartment room to protect your privacy, so as not to be eavesdropped. Therefore, it can be expected to be an inexpensive method to prevent eavesdropping.

However, this method of preventing interference requires some precautions to be kept in mind.

Notes on using interference

Cannot completely prevent interception

There are two types of scramblers, but neither can completely interfere with listening.

The performance of 3G/4G mobile phone jammers that the general public can buy is very limited, and the type of blocking/blocking radio waves can interfere with radio waves up to 2.4Ghz, but cannot block radio waves beyond this range.

Also, the type of sound that is hard to hear does not mean that you can mute it by completely muting your voice, as the name implies.

You may need a license to use the scrambled device

Some models send mobile phone interference signals. This powerful interference radio can only be used with the permission of a third-level professional terrestrial radio technician.

If used by an undocumented person with interference model qualifications, a violation of the Radio Law will result in severe penalties.

Even if you block the interception of spies, it will interfere with the communication of the phone, so it is difficult to hear or hear the communication with the phone. There is a danger of touching people.

You will not be caught in commercial facilities or public transportation

Blocking commercial facilities or public transportation violates the Radio Law.

Even if it is unethical to use a mobile phone on a bus or train, do not bring the jammer into the car, but only use it as a jam avoidance device.

In order to prevent eavesdropping, there are plans to install interference in the home or office, but there are restrictions where interference can be installed and where interference can be used.

Jammer-mart’s mobile phone signal jammer is recognized by consumers

Many friends who use mobile phones have this kind of distress, that is, the signal of the mobile phone often has problems. Especially friends whose home is in the country, can’t chat online all day long. But after some friends used Saiyue Communication’s cell phone jammer, this problem was completely solved.

Whether it is a branded mobile phone or a copycat mobile phone, they often encounter poor signal problems. The cell phone signal booster of Saiyue Communication was born under this situation. This is a cross-age product, so it is very popular in sales. Whether online or in physical stores, many consumers are buying.

But at the same time, there are also many companies that seize the tricks and follow the trend, all of which are producing mobile phone signal amplifiers. This is because with the increase in mobile phone users, mobile phone signals have received serious interference. Because Saiyue Communication itself is a well-known company specializing in the production of mobile phone signal amplifiers. Now everyone in the industry knows that if you want to have a good mobile phone signal amplifier, you must choose Saiyue Communication. This is a testimony of strength, and also the affirmation of industry insiders and consumers.

Pros and cons of mobile phone signal jammer

Nowadays, with the rapid development of science and technology, traditional mobile phones are becoming more and more intelligent, and they have become an important communication tool indispensable in people’s daily work and life. Of course, the negative effects caused by mobile phones are also immeasurable. Negative impacts in special scenarios and specific times have become new leak channels and new criminal methods, posing a threat to the security of confidential information. Therefore, it is urgent to strengthen the management and standardized use of mobile phone signal blockers.

Mobile phone signal jammers are mainly used in places where no mobile phone communication is required, such as in various examinations, office premises of confidential departments, gas stations, etc. Because of their easy installation and simple use, more and more companies use signal blocker. And the equipment signal is always in a relatively static state, which will not interfere with other electrical equipment, and has played a certain role in some special places.

GPS signal jammer

The mobile phone signal jammer is also called mobile communication jammer, mobile phone signal isolator, conference security device, etc.The signal jammer transmits a strong signal consistent with the frequency of the mobile phone’s downlink frequency band, and is tuned with the signal sent by the base station to the mobile phone, so that the base station sends to the mobile phone The downlink signal is deformed and cannot be recognized by the mobile phone, which interrupts the connection between the mobile phone and the base station. Simply put, its main function is to make the phone unable to use normally. Its essence is to implement electromagnetic interference to the wireless network on which mobile phone communication depends, so that the mobile phone cannot access the network, and thus cannot receive information from the mobile network, and cannot send information through the network.

However, with the promotion of signal jammers, it has also brought some adverse effects. The wide use of signal jammers will interfere with the normal use of surrounding residents, causing residents to use mobile phones without signals. If the shielding range is shortened, there will be a lot of It is also difficult to control the blind angle and blind zone, the shielding edge distance, and the long-term coverage is wide, the power will be large, and the radiation generated will also affect the human body. Therefore, the quality of a mobile phone signal shielding device depends not only on the The effective shielding degree of mobile phone communication signals, but also whether the radiation pollution produced by it meets the national electromagnetic radiation protection standards

Especially in government agencies, once the staff of the agency accidentally leaked the content of their work, they could easily be stolen by illegal elements. This is a very dangerous thing for agencies and agencies. In order to prevent such incidents from happening, government agencies will be equipped with mobile phone signal jammers or mobile phone signal shielding cabinets to avoid leaks.

Install Cell Phone Jammers To Avoid Road Accidents

This is a question you should consider today. You may ask me: why should I worry about this? In response to your question, I would like to say that despite the fact that it doesn’t seem like a problem (for example, in relation to texting while driving), this topic is more and more popular these days. That is why I ask you to think deeply and consider various options. You also provide cell phone signal jammer to choose from.

Powerful signal jammer device

There is no law against texting while walking. But a town called Fort Lee in New Jersey almost passed such a law. Ultimately, the law was not approved and a few state walking safety programs were launched in March, as two fatal pedestrian crashes occurred in Fort Lee within 24 hours of February this year. . In addition, 117 pedestrians were fined for using crosswalks without using or using a cell phone.

Whether you are driving or crossing the road (or using a crosswalk), texting while driving or walking will not only put your life at risk, but the lives of others around you as well. For example, you text when going to the crosswalk, but you don’t see red lights and green cars. You start to cross the road, or you are hit by a car (especially if the driver is also texting and can’t see you), or the driver will apply hard braking and be hit by a car driving behind them. Or realize that he won’t be able to stop in time and is ready to stop his car from hitting you, he will turn to the sidewalk to take more time to rest. And no one knows how it will end … I suggest installing cell phone jammer around traffic lights, in order to eliminate the danger of looking at the phone.

To solve this problem, different countries use different methods. For example, in London, for pedestrians texting while walking, they would see loads on the poles, and when they hit the poles, they wouldn’t take much damage. Does that sound funny? Yep, it’s fun watching someone in that situation, but when you hit that post with your head, it’s definitely not that fun. However, for all pedestrians, including you, there is another option – you can prevent texting while walking and make your life and that of many people around you safer.

UAV signal race-the importance of jamming technology

With the rapid development of the drone industry, some individuals and groups have begun to use drones for malicious purposes on a global scale. Many companies are paying attention to this trend and trying to enter the anti-drone industry. They introduced various drone guns, anti-drone shooting, attacking birds, cyber artillery, lasers, missiles, GPS jammers, radio transmitters and more.

The drone did not seem to hit the projectile and laser when it landed (although this kind of evidence will definitely change this analysis). In addition to physical projectiles, there are three known non-dynamic methods to stop drones. Radio frequency (RF) interference, global navigation satellite system (GNSS) interference and deception. Radio frequency jammer disrupts the communication between the drone and its operator, usually causing the drone to descend or return home. With GNSS, the drone will lose its link with the satellite navigation. After that, the drone will usually hover, land or return to its original position. The attacker used deception to provide new information to the drone to control its flight.

By the way, the operation on the Crimean Peninsula was a great success, without bloodshed, because all Ukrainian military communications were cut off. I’m not sure about the mobile phone, but it is not allowed to use it as a military communication channel. Therefore, the Ukrainian army did not resist because it did not receive an order from Kiev. They don’t need much… Many people just joined the Russian army and navy enthusiastically.

It did not “close” anything. First, it will cause a big sensation on the radar oscilloscope, until the software or personnel press the “search for interference” mode button. Then lock the weapon system on the jammer. In a real war, the jammer will disappear within a few seconds. The American ship did not want this to be a fierce war, so it made the destroyer think it was evacuating it. You’re welcome.

China will continue to develop features designed to limit or prevent the enemy’s use of space-based assets in crises and conflicts, including the development of directed energy weapons and satellite interference.

The problem is that many potential enemies, including the Chinese and Russians, are developing advanced digital radio frequency memory (DRFM) jammers. These jammers effectively remember the incoming radar signal and repeatedly send it back to the sender. This will greatly reduce the performance of Friend Trader.

Can the test signal blocker block all communication signals?

Can the signal blocker block all communication signals? Having said that, many people are a little unfamiliar with test signal jammers. In fact, it has been widely used in the college entrance examination room. In the college entrance examination last year, many examination rooms were equipped with this kind of equipment. The response was very good. Practice has proved that this method has a good effect on eliminating electronic signal cheating. Starting this year, it has been vigorously promoted to allow more examination rooms to be equipped with this shield.

5G frequency jammer for sale

The emergence of shielding devices now solves many hidden dangers that disrupt the order of the examination room, allowing candidates to take the exam in a fair environment. The principle of the test signal shielding device is to disable the communication signal of the mobile phone by isolating the electronic signal, thereby preventing the use of the mobile phone to cheat. Not only that, it also has a good shielding effect on WIFI2.4G signals. Generally speaking, the effective range is within a radius of 0 to 30 meters. Generally speaking, a low-power test signal shielding device is sufficient to cover the entire classroom. It satisfies the test room’s requirement for shielding signals. Since the battery life of the device is generally three hours, although the heat dissipation is not good, it also leads to a particularly high cost performance, which is especially suitable for schools to buy test room signal shielding. Worry about buying test signal jammers is a common problem for many customers. At this time, you can contact Shankino and ask about the price of the test signal jammer. It is a manufacturer with many years of high quality and rich experience in research and development of shielding devices. With a first-class technical team to provide technical support for product quality, it is favored and selected by customers.

Portable jammers are more complicated than desktop jammers

It is said that GPS tracking equipment is usually installed on a part of the car. Some people are afraid of GPS. The most common GPS threats in life are common. You can now see that jammers are used in many places. By emitting interfering radio waves of the same wavelength as the radio waves of GPS satellites, the GPS positioning function may be hampered. The radio waves emitted by the equipment that I have confirmed are very weak and in the weak radio wave range defined by the radio law. Some equipment is suitable for cars. There is a car loading design.

Portable Mobile Phone Jammer

This is a device capable of blocking radio waves to the car’s GPS receiver. They say GPS jammer is on the market. If the device freezes, the phone will be out of range and the phone cannot be used. There is a handy GPS circuit breaker that supports these devices. A car charger is also included, so you can charge while racing. Within seconds, navigation cannot be done like GPS. Determine the ability to receive obstacles. Even if the output is small, interference may occur. The phone is convenient because you can do all kinds of things. You have to understand that this is advanced tracking technology. There are currently many GPS tracking apps with location tracking capabilities. It usually goes unnoticed, just like being watched by someone all the time. Personal confidentiality may have been disclosed. Some interfering devices may avoid tracking. The radio waves from the smartphone may be cut off. The mobile jammer has a high power design. There is a strong range of interference.

Robots with cameras are very dangerous

The robot industry is one of the cornerstones of modern technological development and global progress. In this field, not only amateurs, but also professionals, there are many innovative thinking and enthusiasts. One of them is the famous iRobot company, which made a lot of cool robots, such as iRobot Warrior or iRobot Roomba. Therefore, the IEEE visited the video from its headquarters and found out many different and interesting things about the technology and development of iRobot robots.

These robots can be autonomous or remotely controlled. They also have many different skills and functions. For example, many robots are created from inspiration from nature. They are crab-shaped and can move over different terrain to adapt to the surface. Or there is a worm-shaped iRobot, which can work in a working oil rig, move around tight places, and reach places that are inaccessible to people.

With iRobots, you can move around difficult conditions (like nuclear power plants) after accidents or other environments that are extremely dangerous for anyone. There are also very few types of iRobots that can mimic human emotions and even facial expressions (remember Japanese robots).

The next category of iRobots is exploratory. For example, some robots can climb any type of wall or other vertical surface: glass, wet surface, smooth surface or any other surface. They use suction cups and push air into them to do the job. In addition, they can withstand a good weight, like 6 packs of soda, while the size of the robot itself is small. Imagine how many devices it can carry!

There are many different sensors on iRobots. They may realize that someone or something is touching or hitting them, which makes the two things different. According to their sensors, the robot will react. Robots can also react to sounds and distinguish themselves based on sound volume. Additionally, iRobot Roomba can find obstacles to avoid, such as walls or stairs.

8 Bands High Power Portable Jammers

iRobot has also created a small robot that looks and behaves like the Recon Scout XT from ReconRobotics. Soldiers can put them in their pockets, throw them into buildings, and use them for remote surveillance. Or there is a robot that can elongate its “neck” with a camera to a height of 8 feet to spy on high walls and fences. Or there’s another voyeur robot, which is small enough to move under the door like a worm, with a miniature camera on it. If you want to prevent others from spying on you through drone jammer, you can use jammers to prevent others from spying on you.

Although iRobot has fully autonomous self-driving cars (pre-Google cars), most surveillance robots are still remotely controlled by humans, as the full robotic automation technology is military grade and expensive. Additionally, there are iRobots called Swarm (not to be confused with the flying SWARM I wrote before), which can communicate with each other, assign a group leader, and complete tasks as a team. If the leader is arrested or destroyed, he will choose a new one from the remaining robots in the group.

As long as modern robots can do a lot of things like jumping, flying, balancing, etc., almost anyone can use them to hide people who are lost during the day and night. One of them can be you. Therefore, in order to protect your life from evolving threats, you can use jammers on robots which can be adjusted to block all frequencies (Wi-Fi, Bluetooth, standard remotes, GPS, GSM, etc.) that ‘they use.

Mobile jammers confuse operators and manufacturers

The unwanted ringing of telephones in the middle of a movie or concert, soon more than a bad memory? Industry Minister Patrick Devedjian definitely hopes that. On October 10th, it issued an order authorizing the installation of “cell phone blocker” to disable cell phones in theaters and cinemas.

This ends more than three years of floating. Because the law of July 17, 2001 (which establishes various provisions of a social, educational and cultural nature) “allows” this type of disturbance “both for emission and reception (…) in the enclosure of the theater. The regulator for Telecommunications then issued a decision to “establish, at a technical level, the regulatory requirements for the use of these devices.” This decision, which was sent to the Ministry of Industry in late June 2003, had to be approved before it could be applied.

This is what Patrick Devedjian has just done, concerned about the “catastrophic impact” mobile ringtones could have “on the revenues [of the cinema operators] and therefore on the film’s bottom line,” he added. he explained on the France Info microphone. Installing such filtering or jamming devices will be the responsibility of cinemas, theaters and concerts, he said. Remember that since September 9, 2002, the Judiciary Orientation and Programming Act also authorizes GSM jammers in prisons.

The icing on the cake for cinemas
In a press release, however, the minister recalled two principles that power halls and manufacturers are obliged to adhere to. On the one hand, “jammers must not cause the success rate of calls outside the room to deteriorate.” On the other hand, their “location must not stand in the way of the application of the regulations applicable to emergency calls”.

This measure enthused Jean Labbé, President of the National Federation of French Cinemas. At France Info’s Airwaves, he welcomed this decree, which “is the result of a long request [from] extremely diverse cinemas, ranging from large to small exploitation”. For him, “the jammer approval is icing on the cake” after efforts and investments have been made to improve the comfort of the rooms.

Others are far from sharing this enthusiasm. “It is a radical decision,” one of the three mobile operators told ZDNet. “These cuts can create security issues and urgent objections.” In 2001 all operators had unsuccessfully applied for the withdrawal of this measure during the ART consultation on this issue.

Challenge from Brussels and several EU countries
Same story at Orange: “Good communication is enough to curb the problems of good manners in theaters,” said a spokesman. As evidence, he said: While the number of cellphone-equipped customers has doubled in a few years, inappropriate behavior has not necessarily increased.

The operator is highlighting the “Citizens’ Campaign” that has been running for several months with posters to encourage customers to switch off their cell phones or let them vibrate on trains or in cinemas. And is concerned about possible overflows from these filter devices: “Who knows if this won’t cause problems with the neighbors upstairs or with people on the street?” Asks the Orange spokesman. France.

Henri Asenkat, President of the Association of Manufacturers and Industrial Companies for Cellular and Professional Radio Communications (Acirp *), also reiterates his opposition to the process. “We had long conversations with ART to explain to them that we are not cheap because of the ethics of the manufacturers who want us to network,” he said.

“We also claim that this is against European regulations.” In 2001, these manufacturers tried to convince ART that this provision violated several European directives (**) with no result. Despite several detailed comments from the UK, Denmark, Finland and the Commission itself contesting the jamming principle, the regulator sent its decision to the Department of Industry in June 2003.
