Kalashnikov konzian, one of Russia's largest weapons manufacturers, unveiled for the first time a drone jamster designed to shoot down uavs, the rex-1 anti-drone electromagnetic gun, at the army-2017 international military technology BBS in Moscow on Sunday.

The Russian state ministry has announced that drone jammer will be used during the 2018 World Cup in Russia to ensure that nothing happens during the match. Drones can be used in sports competitions. Coaches can learn more information about players' actions through aerial photography in training, so as to conduct targeted guidance and improve the tactical level. Obviously, aerial photography technology, which used to be complicated and extremely expensive, has become very easy after drones came into the consumer domain, bringing us more new perspectives.

The Russian military has been blocking signals from us drones fighting over Syria, saying it is seriously affecting us military operations, according to four us officials, NBC news reported Thursday.

Changsha, feb 9 (chinadaily) -- a drone jammer has been tested at changsha huanghua international airport, in an effort to eliminate the security risks caused by the black flight. It is reported that after passing the test, the anti-uav system will be put into use in the near future to protect the safe take-off and landing of flights.

Former British prime minister Winston Churchill famously said during world war ii, "by fair means or foul, the highest morality is attained." If it were not for the personal practice of journalists and the outspoken inventor, who would have thought that such a high-sounding anti-cheating advanced tool was singing in the red light of health and rights. Admittedly, cheating on the gaokao is a headache and a hassle, but the convenience of regulation at the expense of health and avoiding the law is striking. In order to "eliminate cheating" of the "highest moral" and by hook or by crook, in the context of supervision collective lost voice, by illegal or legal means to urge the world students to abide by the law, which itself is the biggest funny.

The college entrance examination has entered the countdown, in the vast number of teachers, students and parents to prepare for the exam at the same time, all over the "cheat pen" "openly listed", and style has been constantly updated and upgraded. Some economists pointed out that: cheating in exams is ostensibly for the sake of scores, but actually behind the scores are more practical interests, revealing a lot of alarming alternative information...

There are three kinds of mobile phone signal blockers. The built-in cell phone jammer are cost-effective and cheap.

Generally speaking, the school will use a cell phone jammer in one classroom. If some classrooms are close to the signal source, each classroom may consider to add more sets to increase the effect. At the same time to avoid purchasing to some inferior mobile phone signal shielding device, can choose the brand public praise good mobile phone signal shielding device, such as Jin Yu mobile phone signal shielding device, specifically for the examination room they have to use mobile phone signal shielding device, so that it can be a one-off use examination room dedicated machine, all kinds of trouble, also facilitates selective difficult customers.

On March 7, 2019, radio management agency of dazhou city, sichuan province organized a meeting of "dazhou standard management work on cell phone jammer", which put forward requirements on how to further strengthen the standardized management of mobile phone signal blockers in schools of the city and prevent the occurrence of man-made interference in public communication events. Dazhou economy and information technology bureau party members, deputy director wang jun and other leaders attended the meeting. More than 30 persons attended the meeting, including municipal confidentiality bureau, municipal education bureau, sichuan university of arts and sciences, dazhou no.1 middle school, China mobile, China telecom, China unicom dazhou branch, and economic and information bureau of counties (cities, districts). Dazhou city radio management section chief wang qiang presided over the meeting.

Last year, mobile phone jammers with signal jamming functions were installed in many examination halls as a technical means to prevent cheating by exam administrators in various regions. However, on May 24, an article titled "the founder of mobile phone blockers claims that cell phone jammer are harmful to people" was widely reprinted by the media.

Wuxi meicun high school has installed a mobile phone jammer in the boys' dormitory building in order to prevent students from playing mobile phones in the middle of the night from disturbing their rest. In this regard, there are students applauded, that the school is for their own good; Some students think this is a sign that the school does not trust students, and the signal shield is radioactive, which will bring bad effects on students' health. On this issue, parents are basically unified, that is, agree with the school's approach; As the competent authority, the education bureau is not encouraging this, and it is up to parents to decide whether schools should install cell phone jammer.

A few days ago, qingyuan radio management office received a complaint from mobile phone users, which reported that the communication base station located near jiafu industrial park suffered from unknown interference, resulting in two sectors not working normally and affecting the normal communication of a large number of users. The office immediately dispatched radio law enforcement and surveillance personnel to the area to conduct a screening. After testing, it was found that the jamming signal came from the factory of a travel supplies company in jiafu industrial park.

Nowadays, many parents of students around me are keen to buy a blocking device at home to control their children to use mobile phones to surf the Internet. I also want to buy one. A few days ago, the liu gentleman that lives in binhai new area tanggu makes a phone call to say to this newspaper news hot line, his son goes up this year early 3, often play mobile phone in the home, communicated with him a lot of times, but all the time without the effect, because this he wants to buy a cell phone jammer to use will control child mobile phone to get online. "I don't know if it's going to have any impact, so I'm still hesitant." Liu explained to reporters.

Students addicted to mobile phones is a big headache for parents and schools. A middle school in hangzhou has come up with a "new solution" : install a mobile phone signal shielding device on campus and turn it on regularly every night to prevent students from playing mobile phones at night. However, in recent days, online voices said that some residents living nearby said that their cellphone signals were not very stable when using them at home, and suspected that the school's cell phone jammer were involved.

On June 3, Mr. Zhang, who lives near the no. 1 high school affiliated to central China normal university in wuhan, noticed a sudden deterioration in cellphone signals. After the field monitoring by hubei mobile company, it was found that the source of interference came from the signal amplifier illegally installed by residents in a small area near the school, and it is not ruled out that the signal amplifier will be used for cheating activities during the college entrance examination.

We are all familiar with cell phone jammer, but those who have participated in major exams have seen them. They are placed in the doorway of the classroom where the exams are taking place. This is a harmless signal to block the signals. But a lot of times people wonder if it will affect the signal radiation of the base station, so that there is no signal in an area.

China's traffic police departments have adopted all available equipment and unconventional measures to crack down on serious traffic violations, with fewer traffic violations such as drinking and unlicensed traffic. Reporters learned today that in National Day, the eve of the Mid-Autumn festival, in order to prevent drunken, undocumented and other illegal ACTS rebound, the city traffic police department increased equipment investment, "cell phone jammer" on stage, the city directly under the five brigade will hold new weapons to human interference to say "no".

In the national chess individual competition site, reporters inadvertently found three gray instruments. Come close to observe, it is examination room professional mobile phone signal shield. Mobile phone signal blockers were installed two days ago to prevent players from cheating, organizers said. Chess games should also guard against "Lao qian", which sounds funny and annoying.

Classroom signal shielding device installed, as long as the teacher pressed the button, all mobile phone change board brick. The teacher's mastery of this technology will undoubtedly make students "shudder".

Two pieces of anti-drone news have been circulating on the Internet recently. One is that the UK has developed an anti-drone System called AUDS(anti-uav Defence System), and the other is that researchers at the Korea institute for advanced research in science and technology (KAIST) have used sound waves to jam the drone's airborne gyroscope. As a matter of fact, with the popularity of micro and small drones, how to regulate them has become a headache for government agencies around the world. Drones have caused numerous troubles around the world. The White House, the Japanese imperial palace and the 101 building have become targets of drone intrusion.

According to the PLA daily on October 29, a ministry of the xinjiang military region demonstrated a new type of anti-uav equipment -- electromagnetic interference ray gun during a practical exercise. On October 19, an unmanned reconnaissance drone flew into the air and circled at an altitude of about 300 meters, the report said. Real-time high-definition footage from the drone was shown on a large screen at the command post, with fist-sized rocks visible on the ground.

The drone jammer, Siraf, was built by cadets at the Isfahan artillery academy. According to the instructions, the drone will have a working radius of 100 kilometers and will be equipped with instruments (including "laser" instruments) that will interfere with enemy uav observation systems.

It is reported that Perfectjammer recently launched DroneSentry and DroneSentinel two sets of drone signal jammer, and has begun to accept orders, will soon be deployed in the United States.

With the development of economy and society, mortgage car has become a kind of automobile consumption. The original owners because of the need for money on the cheap mortgage of their own luxury cars, if later still fund turnover does not exceed the deadline, will lose the ownership of the vehicle. Mortgage agencies ultimately want money, not real goods, so they sell their cars. As a result, buyers of mortgaged cars have the opportunity to buy luxury cars at lower prices.

Vehicle GPS signal jammer are important to some customers. For example, the mortgaging car company temporarily gains the control of the car after releasing the money to the original owner. In order to prevent the car from being secretly taken away by the original owner, such company will buy GPS shielding device and install it in the parking lot where the car is stored, so that the original owner cannot locate the car and thus protect the property safety.

Now some product appearance is very similar, but the quality of each are not identical, in the process of buying a GPS signal jammer, can truly have the right method, and then judge the quality of the product, on this basis, the complete purchase work, based on this for us, but some people in the process of buying, they are not entirely clear, want how to judge the quality is ok or not? There are many different ways to do the same thing, and when you understand it correctly, you will naturally get the desired result.

With the second-hand car and mortgage car business becoming more and more common in economic activities, in order to protect their own vehicle property safety, car buyers and car sellers have begun to realize the importance of GPS signal locator and its opposite GPS signal jammer.

First, we need to know what 5.8g WiFi is. 5G VIFI frequency the lower the frequency, the better through the wall; The higher the frequency, the faster the speed. 5.8g WiFi works at a high frequency of 5000MHZ, which supports fewer terminals. 2.4g WiFi works at 2400MHZ frequency, which is supported by earlier WiFi frequency terminals. Although the WiFi chip of mobile phones supports dual-frequency operation (2.4ghz and 5GHz) before, the protocol adopted is still 802.11n standard, and the latest 802.11ac standard is not adopted, which is not 5G WiFi in the real sense. It can be simply regarded as using 802.11n WiFi on 5.8g frequency band, and the performance is somewhat discounted.

Currently, cell phone jammer on the market are all in the full spectrum, and one can block 3G, 4G WiFi and GPS Lojack. It can effectively shield: CDMA: 867-885 MHz, GSM: 923-964mhz, DCS/4G: 1803-1994 MHz, 3G (unicom/telecom) : 2109-2175 MHz, mobile 3G: 2395-2487 MHz, 4G1: 2298-2406 MHz, 4G2: 2547-2650 MHz.

With the continuous development of mobile phone this mobile communication tools and popularization, improving continuously the personal mobile communications technology, especially the 2 g, 3 g, 4 g, 5 g technology promotion and application of the step by step, like prison, reeducation-through-labor centers, detention and rehabilitation centers, school examination room, meeting room, church forces, military area commands and similar areas is more and more prominent, the negative effect in the prison, detention and other places of regulation, cell phone mobile communications tools were banned, not only for the prisoner, so should to regulators. Once the mobile phone is brought into the prison and put into use, it will bring great harm to the management, safety and development of the prison. Some prisoners through illegal smuggling mobile phones in prison, phone calls, text messaging, access to materials and threatened witnesses, to the state confidential information leakage, the use of mobile phones for illegal trade, transfer confidential information with the outside world even form a gang and organizations such as prison break, etc., and because of that, in drug prison jail the labor camps and other places to install cell phone jammer

It depends on the speed at which 5G mobile signals become ubiquitous. Although small-scale 5G trials have been launched in several regions, and the first 5G phone card was given to SOHO chairman pan shiyi by China telecom the other day, with the last number 0001, because of the partnership between the two companies, it is far from widespread commercial use.

For better shielding effect, cell phone jammer can also be placed on a chair or table with a distance of 1.5-2 meters from the ground. Of course, it can also be placed on the ground directly, depending on the local wireless signal strength, or it can be placed in front of the classroom, to better protect the shielding effect.

In Russia. School teachers in Russia began to clamp down when they noticed surreptitious pupils using their smartphones to look up answers and prompts during the tests. In a major crackdown, Rosobrnadzor, a telecommunications business, advised schools to use metal detectors at exam entrances and, if possible, cell phone jammer in exam halls to ban phones and tablets from classrooms. Some people think that teaching children not to use mobile phones in class is just a matter of teaching them respect. But what should children think when they see their parents using them at the dinner table, walking down the street or even driving?

Mobile phones and base stations are connected by radio waves. Cell phone jammer scan from the low frequency of the channel to the high frequency in the working process. This scanning speed can form garble codes in the message signals received by mobile phones. Mobile phone performance for search network, no signal, no service system and other phenomena.

In many situations in our lives, such as examination, meetings, etc., using a mobile phone is very inappropriate, this time in addition to early mobile phones confiscated, can use cell phone jammer, will be within the scope of the particular occasion, wi-fi signal shielding the signal, not the mobile phone signals, access to the Internet, we wouldn't go to play mobile phone, it's very good reach the expected effect.

The cell phone jammer power is very small, the scope of action is only 20 or 30 meters, will not cause interference to the mobile phone base station, and the application in a specific situation, can not talk about endangering the public information security. The electromagnetic signal frequency it sends completely falls within the working frequency band of mobile phone stipulated by the country, and this signal is always in a relatively static and constant state, so the regular mobile phone signal shielding device will not have an impact on any other electronic devices, nor will it interfere with people's brain and affect people's normal thinking.

As we all know, with the progress of science and technology, high-tech cheating methods emerge in endlessly. However, with the attention of educational institutions,cell phone jammer are gradually introduced as countermeasures.

With the progress of science and technology, mankind has entered an age of explosion of science and technology and information. Mobile phone has become an indispensable communication tool between people. First, QQ, which is mainly based on chat, appeared, enabling people to get to know strangers thousands of kilometers away. Later, WeChat came out. It can be said that science and technology makes the upgrading of numerous electronic products more frequent, and the powerful functions make people more and more dependent on electronic products. Teachers also use APP software to assign homework for students, and various live broadcast platforms, game software, social software and so on on mobile phones.

Nowadays, although the rapid development of wireless communication greatly facilitates people's life all over the world, it is also abused by criminals, which has seriously endangered people's life safety and law enforcement justice. In prisons, inmates can use mobile phones to direct outside associates from their restricted cells to continue illegal activities. Behind the scenes, they plan to exonerate, command silence, and even contact outside accomplices to carry out prison riots and escape. The perfect solution to this problem already exists -- a high-powered cell phone jammer designed for prisons and larger Settings.mobile phone signal shielding device can completely eliminate the possibility of prison inmates using mobile phones to communicate.

Strictly speaking, no. The cell phone jammer installed in the examination room can completely screen the mobile phone signal from the performance or point density, making the mobile phone in the state of no signal, so that the mobile phone is not able to send and receive text messages and Internet access. Some venues deliberately didn't block operators' 2G spectrum, which allows voice, text and Internet access, for special needs. However, now operators are making great efforts to develop 3G and 4G networks, and 2G networks only take on voice and short messages. For example, China mobile will switch back to 2G frequency band for communication when making voice calls without opening VOL call function. Now it is very, very slow to surf the Internet with 2G.

Is there really a shield of 10,000 square meters of cell phone jammer, the answer is certainly possible, theoretically shielding the shielding distance can be infinite. Theoretically, as long as the jammer is large enough, the interference distance can be infinitely large. So as long as the laboratory level of large jamming equipment, theoretically can reach a distance of 1000 meters

Recently, a netizen revealed that a university has installed cell phone jammer and mobile phone shielding bags in the classroom. The netizen expressed his dissatisfaction with the university and pointed out that such strengthening measures are not reasonable. On the afternoon of September 17, a reporter from the local daily learned from the school that the reason why the school installed the mobile phone signal blocking device in the classroom is to build the examination room for graduate students, and the purpose of setting the mobile phone shielding bag is to enhance the teaching construction and improve the classroom order and supervision.

In the field of mobile communication, a cell phone jammer is a device that blocks transmission by generating jamming signals. Mobile phone signal blockers emit signals in the same frequency range as mobile phones, and within the range of mobile phone signal blockers, mobile phone users may lose their signal. Cell phone signal blockers are usually undetectable, and users may experience minimal effects, such as poor reception. Jamming devices can be used anywhere, but are often deployed in places where cell phone use can be disruptive, such as in libraries and restaurants.

First, let's popularize the relationship between price and power. Cell phone jammers are divided into low power, medium power and .

The power of the machine itself. Now on the market, many machines are said to be 5W, the actual power is less than 1W. So, it has to be actual power. For small power machines within 1W, the shielding distance is about 1-10 meters, and the shielding range is 10-30 square meters. Remember, these cell phone jammer don't go through walls.

Hello, we have known your situation. First you need to know how a spy device works and how it works in frequency. The device usually USES low frequency radio signals and mobile communication signals

Hello, our team of experts have discussed your idea. Have to say that your idea is very interesting, and has certain feasibility. First of all, the chaos of the unmanned aerial vehicle (uav) market does need to governance.

Hi, my friend. We have learned that you. It seems you are facing government surveillance. Now with the mature of unmanned aerial vehicle (uav) technology, the government gradually reduce human input, start using unmanned aerial vehicle (uav) tour of the city

As far as we know, 5G is still in the trial operation stage. There is still a long way to go. It is expected to take at least another 3-5 years for 5G to become fully ubiquitous. And even if 5G comes out, 4G won't be phased out. So 4G cell phone jammer could be around for a long time. So 4G jammers should still last a long time

As we all know, 5G will be popularized by 2020 at the latest. So, this could mean that all 4G jammers may be about to fail. Therefore, more and more people are eager to get 5G cell phone jammer. Because 5G jammers can jam 5G,4G,3G,2G signals. So, even with the popularity of 5G networks, the device will still work. That's why more and more people are asking where they can buy them.

Being tracked by a GPS tracker sounds like a movie. But it does happen in our daily lives. GPS trackers are getting easier to buy in North America. Every day, we are followed without being aware of it. As a result, more and more people are seeking solutions. Until the GPS jammer came along.

Since huawei proposed to study 5G technology, the door of 5G information and communication era has been opened. As the research progresses, huawei is about to release its first 5G mobile phone in 2019. And China has begun to experiment with the actual use of 5G signals. It is expected that China will have achieved 5G signal network coverage by 2020.

The safety of driving has always been a very important issue in the United States. Every year, 5,000 accidents are caused by drivers using mobile phones while driving. But, no doubt, you can't stop young people from using mobile phones. This is undoubtedly a very big problem for traffic safety. You can't imagine how dangerous it is for young people to talk on the phone while driving. But many people are unaware of these problems before they become dangerous. That's why we need some equipment to drive safely.

Why the need? That's because GPS tracking has become increasingly rampant. As you can imagine, as GPS technology is becoming more sophisticated, GPS tracking technology is becoming more sophisticated. Although this technology makes our lives more convenient, it is a great threat to women. Why do you say that? Because GPS tracking devices are now very easy to buy.

It is reported that the United States a prison warden said need more tools to fight against criminals. According to statistics, 2018-2019, caused by cell phones and uavs to smuggle illegal crime as many as 5000. But detention centers can't do much about these crimes. It's hard for you to catch offenders in prison cell phone use. Not to mention drones that are constantly in the air.

As for the most popular cell phone jammer in North America in 2018, you might think of all kinds of jammer. But when it comes to the most sold jammer, we have to mention EO-08-007 from perfectjammer. According to incomplete statistics, perfectjammer sold more than 100,000 units of this device in 2018. As far as I know, other products are far less than half of the sales volume of this product. Which is why I think this is the most popular jammer product of 2018. Let's take a look at the features of this product

The maximum jamming range of the jammer is increasing all the time. Generally speaking, there are two jamming distances at present, namely, mobile phone jammers and uav jammers. Undoubtedly, the jamming distance of the uav jammer will be much larger than that of the mobile phone jammer

With the development of communication technology, mobile phone has become an essential tool in our daily work and life. But the wide application of mobile phone also brought about vital problems. For example, as a new noise pollution source, mobile phone interferes with your normal working order; as a new insecure factor, mobile phone brings hidden unsafe troubles to some places such as oil station, gas filled station, etc.

As our life becomes more and more intelligent. We can't live without smart devices any more. And more and more people rely on electronic devices. For example, many people keep looking at their smartphones at work. And many students use it. It is conceivable that students can cheat with their mobile phones. People at work can use their mobile phones to be lazy.

GPS jamming is increasingly common. It’s of particular concern for maritime authorities, as ships rely on GPS for accurate positioning information. So it’s been much studied; in 2014, a Master’s-degree thesis on jamming in the high north was published (urther reading), and GPS World, a professional journal, has devoted several articles to GPS jamming, including the one described here.
