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.

What jamming device can stop a truck’s GPS monitor?

Hi guys! The company I work for has installed a GPS monitor in my van. Please tell me which jamming device should be obtained to ensure that the signal is blocked.

I’m using a Wi-Fi connection, but I’m not sure how easy it is to hack. We use Bluetooth and have never heard of Bluesnarfing (Bluetooth hacking technology). And of course, we know how to use GPS to get to where we are and where we need it, but have you ever heard that you can track your GPS navigator?

Every day, more and more people are worried about protecting their privacy. Everyone knows that many of these newly introduced wireless gadgets can steal our personal information, and we don’t know that either.

To achieve your legitimate goal, you need to block the signal of this tracker installed in your van. Therefore, you should use a van GPS jammer to prevent this GPS tracker from sending data about your location to a base station somewhere in your company. This GPS jammer helps maintain the right of an individual to freedom of movement.

As you can see, you always have the ability to influence the situation, even though the company is trying to control you and monitor every move.

GPS jammers keep others from knowing your location

The competition with the tablet development industry is very attractive. Since Apple’s famous iPad changed the world of computing, users like IBM wanted to change it in 1981 and get a handheld entertainment device in their hands as soon as possible.

Artificially since the last month of 2011, Apple iPad tablets have been a steamroller among the competitors. According to Apple CEO Tim Cook, their iPad owns 75% of all tablet sales in the United States. According to reviewers and customers, the biggest headache for Apple’s rivals is that no company has developed a tablet that matches the quality of the iPad. When talking about tablets, Apple’s iOS Android is an easy hit.

But now you can ask: how is this information related to GPS tracking? Frankly, tablet competition can change the way these GPS tracking systems work. Take, for example, Asus Transformer. Consistent with some reviewers, this Android-based tablet computer is the iPad’s strongest competitor, with the exception of the Samsung Galaxy Tab model. Asus has developed a great product with a well-integrated keyboard that makes it easy to turn this tablet into a nice netbook.

Unlike the iPad, and like many mobile phones, the Asus Transformer GPS technology inside the GPS device makes it surprisingly accurate and easy to track your location. But there is a problem. It doesn’t seem to work very well. Asus mentioned customer complaints about embedded GPS in tablets. This can be a bit slow and there is an embarrassing location delay.

So what is the solution? Along the Asus Germany Facebook page, we have developed an update to get GPS satellite signals using the tab Wi-Fi connection. So far, using Wi-Fi to completely replace GPS satellite signals sounds wrong. Wi-Fi signals are not so common all over the world, but signals from GPS satellites can be sent all over the world. Emerging technologies can eventually eliminate this question.

Of course, if you’re very concerned about privacy protection, you can choose the right GPS jammer and simply block the surrounding radio quickly to hide your location.

Can 4G Cell Phone Jammers Really Protect Your Personal Information?

The development of communication systems has slowly evolved from slow network connections to fast network coverage at first. This development is driven by the need for a more reliable, efficient, and congestion-free network that can transfer large amounts of data. The information and communication technology field is not idle. It is always in the R & D program and ensures that it is properly placed in the world of dynamic technology. The jammer shop company wants to share news about 5G networks. South China, an Asian giant of technology discovery, is heading towards the introduction of a fifth-generation network planned as a universal communications technology after 2020.

5G networks are 1000 times faster than the 4G networks currently in use. This is an invention and progress that every country wants to associate with. The Seoul government has promised to support this project and will raise $ 1.5 billion to ensure that the program is implemented effectively.

4G 5G cell phone signal jammer

It has been reported that the entire movie can be downloaded in less than a second using such a network. In fact, it’s unbelievable for other countries struggling to connect their rural environment to 3G networks. Advances in this technology are costly, and citizens, governments, and governments need to upgrade their communications devices to cope with this rapid pace. It’s not surprising that the government is spending such money to ensure the success of American communications technology.

Just as South China developed 2G networks in the 1990s and 3G in 2000, developing 5G networks has many advantages, and the US economy is speculated. I will. The country has 82.7% more Internet users than the United States. This percentage is expected to reach saturation soon, making China a country where anyone can access and use the Internet.

With the growing number of Internet users and the growing demand for more data traffic channels, this upgrade is appealing to many investors interested in communications technology. Huawei is some of the companies that have registered their willingness to use 5G networks. The Beijing government plans to deploy the network from 2017 and will be fully deployed by 2020. If you’re still unsure, you can track your location on a 5G network.

5G networks can connect billions of connected devices. This is a further development of current 4G on video. Using 5G networks reduces the chance of network outages and improves coverage. Good coverage is associated with low power consumption, resulting in lower battery consumption and significantly lower energy consumption.

China’s information and communication technology is a world leader. Genuine news media such as CNN and Miller report increasing use of devices with portable technology over American communications networks. Therefore, in China, 5G does not disrupt the network, so citizens can be encouraged to buy advanced electrical equipment that can be controlled from anywhere. However, keep in mind that all mobile devices and networks can be hacked. Therefore, we recommend using cell phone jammer to protect your personal information.

U.S. Army tests could not stop the new GPS last fall

Last fall, after Russia was suspected of jamming GPS signals in Europe and elsewhere, the U.S. Army will test an anti-jamming GPS to solve the defense breakthrough problem.

GPS jammer can also pose a major threat to the United States and allied forces, and everything from troop movement to guided missile and UAV guidance depends on the system. Last fall, the United States and NATO allies launched a large-scale joint exercise called Trident Juncture in Norway to test the joint preparations and training of a large multinational alliance. During the exercise, the military noticed that GPS signals interfered with signals attributed to Russia by Finnish and Norwegian officials. In April 2018, US officials stated that the Russian military had blocked the GPS system of UAVs used in Syria.

Members of the German Second Cavalry Regiment will be equipped in the fall. According to reports, the Army is considering developing a new generation of inertial navigation system that can be used as a backup system.

At the C4ISERnet conference in Arlington last week, Colonel Nickolas Kioutas, project manager for Army procurement developer Positioning, Navigation and Timing (PNT), said that it’s important to deliver equipment to troops quickly, and the Army is working hard to roll out the Equipment used in the iterative process. Breaking the defense points out that by putting the system in the hands of units like the Second Cavalry, the Army can quickly evaluate technology and make improvements if necessary-without spending years developing and testing equipment that turns out to be the wrong one.

The threat posed by the terrorist drones

Most hobbyists think their drone is a great tool – much less dangerous than a hammer and much more fun.

But there are times when we wonder about the drone’s dark potential. What could it be doing in the wrong hands? However, from a sense of good citizenship, it is unlikely that most drone users would share these thoughts publicly.

Feel free to vent because the U.S. Army Association has voiced your worst fears.

A new report suggests that the increasing use of drones to pollinate plants shows that they can deliver chemical or biological warfare agents (CBW) alike. Additionally, software that allows multiple drones to swarm and coordinate is likely to encourage the spread of these toxins.

Pranks or fake murders?

Lt. Col. Claude A. Lambert, a strategic planner with the U.S. Army Materiel Command, points out some worrying incidents where drones could have wreaked havoc:

At a rally in 2013, a drone crashed harmlessly near Chancellor Angela Merkel
Authorities found a drone potentially contaminated with radioactive cesium on the roof of the Japanese Prime Minister’s office in 2015
I’ll add a newer one: A drone caused a seven-minute hiatus from a Chicago Cubs game last month when it landed on Wrigley Field.
Depending on your point of view, these are either funny japes or mock assassinations. Military must take the darkest view of human nature. Therefore, Lt. Col. Lambert is calling for a national US strategy to detect and identify drone threats. However, he doesn’t have any easy solutions.

“There is no such thing as a ‘magic bullet’ to counter a … threat,” he writes. “Not a single comprehensive material solution will completely eliminate the (drone) problem. Kinetic methods, signal hijacking, radio frequency interference and directed energy are areas that can be explored in order to defeat (drones) in a practical and inexpensive way. ”

He says in July 2019 the U.S. Marine Corps successfully deployed a new portable jammer to jam an Iranian drone in the Strait of Hormuz. But this was a military on alert in a conflict zone. Domestically, the FAA registers around 1,700,000 drones in the United States. Nobody knows how many are not registered. Lt. Col. Lambert believes the military and law enforcement must work closely with academia and industry to counter the threat posed by deadly drones.

Preventing the weapon from drones

He also wants the international community to stop trading chemicals that could arm drones.

Lieutenant Colonel Lambert points out another possible weakness in the drone shield. The U.S. military has minimized its chemical and biological training in recent wars because its opponents lacked these weapons.

“As a result, the joint force is now unprepared to face a chemical or biological warfare threat,” he writes.

“One thing is certain: anyone willing to develop or acquire a CBW agent and deliver it via a (drone) probably cannot be put off.”

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.

mobile phone jammer GSM

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.

Answer common questions about mobile phone signal jammers

1. Is there radiation?
If high-power equipment, such as 5W (37dBm) above the host computer may also have greater radiation. Generally, the output power of mobile phone signal booster is within 200mW (23dBm). After reaching the antenna, it is generally within 5mW (7dBm). After other losses, the indoor signal after installing a cell phone jammer is generally around -50dBm to -75dBm. Good outdoor signals are generally around -40dBm to -75dBm.

When the mobile phone is talking, the GSM mobile phone is talking in a weak signal environment, and the worst radiation power can reach 1W (30dBm). After installing the amplifier, the radiated power of the mobile phone call is about 10mW (10dBm). It can also be said that after installing a small power amplifier in a poor signal environment, the mobile phone reduces radiation when talking.

2. How to distinguish the quality of signal amplifier?

1. Look at the workmanship and choose the brand. If you use more, you can take it apart and compare it internally.

2. There are many inferior signal amplifiers on the Internet, mainly because some circuits for optimizing signals, such as automatic gain control, are omitted. Generally, there are less than 80 devices, and the host with complete circuits generally has more than 200 devices.

3. Inferior cell phone signal amplifiers will cause serious interference to the base station after a large number of installations, making it impossible to make calls when the signal is full. Of course, there are interferences of good quality, but the interference of the same power is several times and dozens of times smaller.

3. Why can’t I make a call when the installation signal is full?

The signal amplifier is a simple device developed at the intermediate frequency of China Mobile and China Unicom. If there is no signal or very weak indoor China Unicom and China Mobile, it should be no problem to use this device. If one party has a full signal and the other has no signal, interference will occur in this case, so it is not recommended.

Mobile phone signal interference in urban village rental houses helps to rest

The shadow behind the splendor of every big city is the village in the city. For example, there are many large and small urban villages in Guangzhou. Shipai Village is the largest and oldest among them. People’s first impression of urban villages is crowded, noisy, and a lot of garbage. The alleys are densely packed, with wires and spider webs crisscrossing overhead.

Because the village is too dense and surrounded by high-rise buildings, the village in the city has a weak signal or even no signal at all in addition to being dark and humid. However, most of the people living in urban villages are fresh graduates or young people who have come to the city to struggle. The lack of mobile phone signal is very difficult for young people to accept. The lack of mobile phone signal not only affects their social activities, but also affects their job prospects. Therefore, many renters hold a mobile phone when they look at the house, and when they come in, if there is no signal in the house, they immediately shook their heads and left.

So, how to solve the problem of bad mobile phone signal? The cell phone jammer is a wireless communication device, which is different from general electrical installations. It may seem simple to install such wireless communication devices, but there are many knowledges in it:

1. First of all, before installing the equipment, fully test the signal and electromagnetic environment to determine the type of equipment, wire and antenna to be selected. To complete this work, it is difficult to do without relevant instruments and professional knowledge. Many people did not understand the reason and bought the equipment and materials at will, but the results were ineffective, and money was wasted.

2. Secondly, during the installation process, there are certain tricks in the design, layout and connection of the circuit. The same equipment and materials, let professional and technical personnel and ordinary electricians to install, the effect will be different, let alone ordinary people.

3. Once the equipment is installed, it needs to be debugged carefully. Equipment debugging is a complex and professional work, which is often far from perfect, and it is difficult for it to be a professional.

4. Finally, the current mobile phone signal amplifiers on the market are mixed, and most of the products are not guaranteed in quality. Many machines only have amplifier circuits, but there are no quality control and anti-interference control circuits. It felt good at first, but it didn’t take long to get worse. Such an amplifier is not only easily affected by environmental changes, but also has a great impact on the surrounding electromagnetic environment, and even interferes with the normal operation of the base station.

At present, many rental houses in urban villages have installed cell phone signal amplifiers, but most of the owners buy them and install them by themselves. In addition, because of the desire to be cheap, the quality of the equipment purchased is very poor, so the signal effect is not good. How many companies have made the outdoor signal environment more and more complicated.
