As we all know, making or answering a phone call while driving can be extremely dangerous and can even cause serious traffic accidents. Therefore, in the future, it is possible to use jammers that interfere with the mobile phone signal in the vehicle to prohibit mobile phone calls and reduce traffic accidents.

How can the villa area interfere with the mobile phone signal to prevent theft?

1. The signal of the villa itself is poor, it is far from the signal tower, and the mobile phone cannot receive the signal in the weak signal area.
2. The thick structure of the wall in the villa area blocks the signal.
3. The signal is bad due to interference.

Since the mobile phone receives signals through the propagation of electromagnetic waves, the base station establishes a connection with the mobile phone by transmitting electric waves, so as to achieve the purpose of voice calls. Therefore, the cell phone jammer of electromagnetic waves will have an adverse effect on mobile phones.

It is normal for the mobile phone to display 4G signal and make a call to 3G or 2G signal! It is not caused by cell phone failure or base station failure. The following explains why this phenomenon occurs:
1. 4G has only one data channel (commonly called the Internet channel); 2G ​​and 3G have two channels, data channel and voice channel. So 2G and 3G can surf the Internet and make calls, while 4G can only surf the Internet because it only has a data channel.

2. In the early days of 4G, in order to satisfy the requirement that the mobile phone can make calls when using the 4G network, a solution called CSFB (Circuit Domain Fallback) was developed. Automatically fall back from 4G network to 2G or 3G network before starting to make calls. But this technology has a disadvantage, that is, you cannot access the Internet when making a call, so it is inconvenient for some business users.

3. Now that 4G technology has matured, in order to satisfy mobile phone users with a better experience, VoLTE (High Definition Voice Call) has been developed, which is a technology that can use the 4G network to make calls while also being able to access the Internet. The mobile phone uses the data channel of the 4G network to make calls and surf the Internet, and the call quality is clearer than that of 2G and 3G.

4. Dropping due to handover failure. Network operators use base stations to transmit wireless signals to serve users. The range of base stations is limited. Therefore, there may be many base stations in an area. The combination of all base stations is a network system. Each base station has its own range. If this range is exceeded, the mobile phone must replace the base station to keep the mobile phone in the network at all times.

Thanks to the invention of GPS jammer to make us safer

With the development of science and technology, people have invented many new useful devices. These products are created according to people’s needs. For example, the invention of the watch is a time when people can know what time is now, and make people have a stronger sense of time and plan to do things. Why are these GPS shields so popular?

GPS trackers have been invented and they have their own market. GPS trackers are a very important invention of the police and military. For the police, GPS trackers can help them easily track criminals. In order to create a thorough criminal gang and catch the criminal gang, it is very important for the safety of the police and the people. For the military, GPS trackers can accurately locate the enemy’s location and send information to us, which is an excellent tool for our military activities.

Although GPS trackers have such excellent functions, GPS trackers are mainly used to track and locate installed personnel. We can use this device and it will also be used by criminals. For some people’s crimes, it may threaten people’s lives and property. All things in the world based on the laws of nature are car GPS jammers invented by people, which specialize in GPS trackers. This kind of equipment is not allowed for private use in many countries, and it is worried that it will affect the police tracking signal criminal groups.

The use of GPS tracking equipment to track events is not rare, and it is very common in our daily lives, whether it is for individuals or cars. GPS trackers can be purchased online in many shops, and with the advancement of science and technology, its design is becoming more and more concealed, easy to hide and install, even if you walk by your side, you are likely to be installed. Therefore, more and more people can buy GPS signal jammers to ensure their safety and personal safety, which can not only be used effectively for GPS tracking devices, but also be vigilant, because you never know when you will install GPS Tracking equipment.

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.

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.

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.

Is the cell phone signal jammer harmful?

It is very interesting that the mobile phone, which is the “enemy” of the cell phone signal jammer, has also caused controversy about security at the beginning of its appearance. However, as people gradually understand the mobile phone, people finally accepted the mobile phone, and In less than ten years, mobile phones have become an indispensable necessity in our lives, and even because of the popularity of mobile phones, a new generation has been born: the thumb generation. This shows the popularity of mobile phones. In the history of human knowledge, the development of one aspect of contradictory things can predict the future of another aspect. Such examples are not uncommon. I think the development of mobile phones as the “enemy” of the mobile phone signal shielding system may be It can provide a blueprint for us to predict the industry picture of the mobile phone signal shielding system.

Finally, I want to tell a true story: when China was building the Daya Bay Nuclear Power Plant in Guangzhou in the 1990s, Hong Kong citizens were very resistant to the project because of the safety of nuclear power. In order to dispel the doubts of Hong Kong citizens, the chief engineer of the project I joked that kitchen knives are also problematic in safety. Kitchen knives can cut fingers inadvertently, and even be used as murder weapons by wicked people. But this does not prevent us from using kitchen knives and does not prevent China from becoming a great food country, because as long as we do our best, we can Can prevent these things from happening. This very superb joke at the time greatly eased the resistance of Hong Kong people to the Daya Bay Nuclear Power Plant and made a small contribution to the smooth start of the nuclear power project.

There is no doubt that technology is a double-edged sword. We all know that mobile phone signal jammers have a certain amount of radiation. In the current situation that there is no authority to define how much this radiation can harm people, what we should do is to start from a people-oriented perspective as much as possible and make good use of technology. Advantages, control and reduction of the disadvantages of science and technology, on the premise of ensuring the safety and health of people, to decide whether to widely use in daily life, not for the uncivilized behavior of a few people, and ignore or even affect the interests of most people .

Mobile jammers can prevent Apple phones from monitoring us

Mobile devices such as smartphones and tablets are considered really dangerous devices because they contain a large amount of our private and sensitive information and have the ability to monitor us. There are many types of exploits and specialized mobile applications that can damage information stored on smartphones or tablets. By the way, the number of malicious mobile applications is increasing and the Android operating system is the leader among them. However, two issues remind us that not only is Android dangerous, but iOS is dangerous as well. We have come across a lot of articles, people said that the iPhone and iPad can monitor us, and these functions are preset by the manufacturer. But the cell phone signal jammer website sells a jammer which can protect the signals of cellphones, which can protect our cellphones very well.

Cell Phone signal Jammer

They said that iOS may contain Trojan horse applications that can collect and analyze user information, create photos and videos, and send all data to third parties. We can tell you on jammer-shop.com that this sentence is really not very clear, because in order to prove these words someone has to decipher the source code of iOS, which is the intellectual property of Apple Inc., and decipher it illegally.

But at the same time, there is a way to steal photos and video data from devices running iOS 6. The vulnerability is exploited in Safari browser. As long as it supports HTML5, criminals can use simple HTML code to steal data from it. This forces users to perform certain activities, but the backdoor exists. We hope it will be fixed in a future update. And the vulnerability does not require Flash or Silverlight plugins, so its range of use can be very wide.

It’s also worth mentioning that in September 2012, a hacker community called “anti-security” claimed that Apple was cooperating with the CIA and the FBI. The community also told them that in March 2012, they had hacked into a Dell Vostro laptop belonging to FBI agent Kristoffer Strangle. They found a file “NCFTA_iOS_devices_intel.csv”, which contained over 12 million unique device identifiers (UDIDs). Which UDID is related to device name, username, address and phone number. Isn’t that awful?

The FBI has officially denied the information, but independent experts have proven its authenticity. Hackers posted this information and many people found their names and devices on this list. Therefore, there are rumors that Apple’s gadgets might spy on us, which doesn’t seem strange and can’t prove it.

Another interesting fact here is that the unnecessarily collected photo and video information can be obtained through positioning data. Now, thanks to the integrated GPS / GLONASS module and the triangulation of the mobile phone tower, they can know the coordinates of each photo and even follow your position in real time. Thanks to the new positioning technology, you can see your position even in indoor areas where GPS is not available.

The realization of such data is possible thanks to the NAVSEA project developed by the army and the University of Indiana. This technology makes it possible to create a high-quality 3D model of the room where the phone is located. This is possible because the data from the accelerometer and the built-in compass are merged with the image itself. This model is much more useful for stealing sensitive data than a set of miscellaneous images.

Therefore, your mobile device may spy on you. Android already has several very dangerous applications, and now iOS has become fragile. It’s really hard to tell if the iPhone and iPad are spying on us, but it is best to consider protective measures before the danger arises, so it may be better to use a cell phone signal jammer. GSM / GPS to avoid tracking and avoid interference. Attempts to hide data transmission.

How to make a signal blocking cellphone pocket?

For some at the National Republican Congress in Cleveland, the choice of protective accessory is an AR-15 rifle that is casually slung over the shoulder. For the Los Angeles-based artist and activist Tim Schwartz, it is a discreet pouch made of matt silver ripstop fabric that houses his cell phone.

This cell phone signal jammer blocks the signal that cell phones keep sending – a feature that Schwartz says is essential during an unpredictable, politically charged event like the Republican National Convention.

“I think it’s sensible that everyone should protect themselves when they get into a situation where they don’t know what’s going to happen,” says Schwartz. In particular, he states, “You can be easily followed by turning your phone on and off.” And if there is a disruption, the information could even be used retrospectively: “The government could request records and show that you were in this area when something went wrong.”

The Electronic Frontier Foundation, a non-profit organization dedicated to protecting civil liberties in the digital world, advises protesters that while their phones are powerful tools for documenting photos and videos, they also contain a wealth of personal information, including contacts, location and message history, emails and private credentials. “Our whole life is on our devices,” says Schwartz.

These high frequency blocking pockets, known as Faraday cages, are readily available to the powerful population that Schwartz calls the “techno elite.” Quartz reported on a $ 720 value of a cash transport and RF blocking bag, and President Barack Obama is traveling with a tent that serves that purpose.

For RNC protesters looking for a cheaper DIY option, Schwartz is holding “office hours” for protesters at the Spaces gallery in Cleveland to sew their own signal-blocking cellphone cases according to instructions from Berlin-based artist Aram Bartholl. Its meetings will take place today (July 19) and tomorrow from 1 p.m. to 4 p.m.

This is a protection that non-protesters could also consider, Schwartz says. “It’s like having long passwords,” he says. “It’s one of those things we should do, but we never get to it.”

Schwartz provided protesters with a copper taffeta fabric, a sewing machine and advice. He says his eighth grade sewing home economics training is appropriate for the job, and notes that the most important step is to make sure all of the edges of the bag are folded and secure.

Here are the directions from Aram Bartholl’s “Kill Your Phone” website. Materials are available on lessemf.com:

Cut 12 cm strips from your roll barrier fleece.
Make pieces of 50 x 12 cm, each for a bag. (i.e. you get 2 pieces of a 1 m long strip of rolls.)
Fold your 50 x 12 cm piece to 25 x 12 cm
Fold the long sides again, 1 cm each, and pin them in place with needles.
Sew two straight seams on the left and right.
Fold the opening at least 2 times! Find a paper clip or clip to close the pouch.
Done!
Schwartz previously developed a tool for victims of the Haiti earthquake to find their missing family members in 2010. He then “fell into the rabbit hole of digital privacy” and worked with the Center for Legal and Information Policy (CLIP) at Fordham Law School to investigate online privacy and reconcile it with security .

In recent years, Schwartz has conducted workshops on digital data protection such as “How to be a whistleblower” at schools like Cal Arts and UCLA, partly in collaboration with the web-based data protection movement Cryptoparty. For the remainder of the month, he will continue his work as an artist-in-residence at Spaces, where he is hosting events like a “dark web treasure hunt” to help people learn more about digital privacy.

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.

Cell phone jammers set the time online

Most lawyers believe that schools can at least prohibit the use of cell phones under certain conditions and circumstances. However, this must be done within an appropriate framework. On the other hand, a ban that goes beyond this scope and prohibits the wearing of cell phones only is largely viewed as unacceptable. First of all, it is widely believed that schools cannot make their own rules at will. You must provide a legal basis for this and follow the principle of proportionality. The school laws of the federal states form this basis, but most of them only have general requirements: the schools can specify measures for the fulfillment of educational and teaching tasks in the school regulations. This can also include restricting cell phone use. This is a common quarrel between related employees: To what extent can a cell phone signal jammer be used to ban cell phones, and what happens if it is violated? Since the ban on the use of mobile phones can also affect the basic rights of students, such as B. Free personal development and property rights, it must be proportionate. In addition, parents may have legal rights so that they must also be taken into account when contacting their children via mobile phones. It has to be proportional. In addition, parents may have legal rights so that they must also be taken into account when contacting their children via mobile phones. It has to be proportional. In addition, parents can have legitimate rights and interests, so that interest must also be taken into account when contacting their children via mobile phones.

4G Mobile Signal Jammer

At the moment, the obvious trend towards the lawyers’ control over the use of mobile phones is barely discernible: For example, the Baden-Württemberg Ministry of Education considers it sensible to ban the use of mobile phones during breaks. However, as long as individual regulations can be formulated appropriately according to educational requirements, this depends on the school.

Special Circumstances for Formal Exams: Wearing cell phones may be prohibited and formal exams are usually more stringent. For this reason, students are usually required to leave their cell phones at the teacher’s desk or elsewhere, and the cell phones they carry can be viewed as a sham. This also depends on the personal circumstances and the detailed provisions of the school and examination regulations as well as the federal school laws. For schools, “primary evidence” may be enough to deceive others. This means that the school can try to deceive if the student’s behavior shows typical characteristics. If the student does not agree, he has to prove that his case is atypical – that is, even if the case appears to be true, he has not deceived.

According to a ruling by the Karlsruhe Administrative Court, it is generally sufficient to have a mobile phone with you so that the inspection can be classified as “unsatisfactory”. If the inspection regulations provide for such consequences for “unauthorized aids”, they apply in any case. In one specific dispute, a student left his cell phone in his room handbag during an oral exam. However, since the school did not clearly indicate the prohibition again prior to the specific inspection, the subsequent rating of “unsatisfactory” for the specific situation was disproportionate. The school had to change the grades again. If there was a cell phone jammer at that point, we could get the same effect without checking the cell phone.

Bavaria has a special state law. In 2006 the school banned the use of cell phones. Pupils must switch off their cell phones “in school buildings” unless they are used “for teaching purposes”, the teacher makes an exception (Article 56 of the Bavarian Education Act). Other federal states have special regulations for schools.

5G jammers, full body scanners on Punjab Prison Minister’s menu to improve work

Ministers said no one except the superintendent was allowed to carry cell phones in prisons. “If an officer is found in jail with a cell phone, the first thing we would do is suspend him.”

The installation of 5G jammer, full-body scanners and other sniffer dogs outside the prisons is the plan that the new prison minister Sukhjinder Singh Randhawa has drawn up for a reform of the department.

The minister, who has firsthand experience of phone phone threats in prisons, told a press conference on Tuesday about one of an inmate’s congratulatory calls: “5G jammers will soon be appearing in the state’s central prisons. A proposal has been sent to the Union Ministry of Interior. ”

“Now we only have jammers for 2G and 3G signals. If we install 4G jammers today after a tremendous effort, it will be out of date when 5G comes in. So we’re trying to install 5G jammers, ”Randhawa said after a meeting with prison officials.

Incidentally, the government’s official press release in the evening spoke of the installation of 4G jammers. “We have three detection dogs in the prison section. We plan to add seven more to check drug and cell phone use in prison complexes, ”the minister added.

Only supdt can transport telephones in prisons

The minister added that no one except the superintendent is allowed to carry cell phones in prisons. “If an officer with cell phones is found in prisons, the first thing we would suspend,” Randhawa said, adding that over 1,500 cell phones were recovered from prisons in 2017.

“To prevent this from happening, the additional chief secretary will instruct the district police chiefs to investigate mobile recovery cases. All prison staff involved are severely punished, ”he said.

Suchen Find permanent documents ’

The minister added that 651 inmates were found to be HIV positive and said the department would improve health facilities in prisons. “We are also planning to introduce health insurance for inmates. I will also ask that doctors be permanently deputized to prisons. The health department only sends its doctors to deputation for six months, ”he added.

He said the prisons were almost full with 22,375 inmates versus the 23,218 capacity. There are 1,119 women and 132 foreigners. Around 40% of inmates who were fined were booked in cases related to the NDSP law. Around 60% of the prison population (13,000) are under-tried.
