Why military jamming technology is needed?

Russia’s accumulated intelligence and electronic warfare tools also include the deployment of Krasukha-4, an advanced electronic warfare system used to destroy radars and aircraft. Sputnik News reported on its presence in Syria, and the country claimed to have discovered a unique GPS jammer system in a video report of a Russian jet at Latakia Syrian Airport. The system and its parabola are shown with a 6-second mark in the video below.

Since the invasion of Iraq in March 2003, a series of active, passive, weekly and powerful saboteurs have arrived in Mesopotamia: Warlock Green, Warlock Red, Warlock Blue, ICE, MICE, SSVJ, MMBJ, Card brand. Dunwood, Juke Box (Symphony) now collectively refer to them as CREW. This is a clumsy acronym for an acronym. The improvised explosive device conducts electronic warfare against the jammer.

As more and more military turmoil floods the theater, the turmoil becomes more and more chaotic. Over the past few months, the Army and Marine Corps have clearly realized the shortcomings of electronic warfare expertise. Major Arch Messi, the commander of the Naval Surface Warfare Center, said: “We put all these boxes here, but people don’t know how to use them.”

This is especially true in Baghdad, where the electromagnetic environment seems to change with the community, the season and the time of day. A Pentagon executive said: “No one knows how much interference will occur on the ground.” This is the interface between the earth and the air at the intersection of the earth and the sky. The Army logistics staff added: “I don’t know that taxi drivers usually make electronic noises, doorbells, garage door openers, and satellite communications because they have not scientifically identified the problem. This is a normal life plan.”

Even for North Koreans, GPS jammer is nothing new, but the latest tests are certainly rare. If there is no ground interference, it may indicate that the device is in the air, but since the FAA only covers airspace, ground interference cannot be ruled out.

In fact, interference may just be a test bed for new anti-jamming technologies that are under development and costly. As the ability to jam GPS every day becomes easier and cheaper, the military is actively developing new systems to enable aircraft, drones, and missiles to withstand jamming signals.

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.

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.

Outdoor Cell Phone Jammers Can Protect Personal Information

As one of the most populous cities on the planet, the official government of Beijing, China will soon start tracking the daily activities of all 17 million people living here by tracking the location of their cell phones. The government has presented a new plan to help reduce traffic congestion by providing detailed information on civic activities around Beijing. The plan is called “Real-time Citizen Sports Information Platform” and will use a person’s cell phone, local cell phone tower and GPS tracking module, which has become a standard module for almost everyone. modern smart phones. Each mobile phone will transmit GPS information to the server, which will provide authorities with unprecedented amounts of data to record the whereabouts and current trajectories of anyone in the Beijing area. For some people with ulterior motives, they may sell privacy for profit, but the various Phone GPS jammer launched by jammer-mart.com may prevent others from monitoring. Critics of the plan say it is another government cover-up effort to restrict individual movement and prevent large crowds from forming on the streets. Their opponents say the data will provide law enforcement with accurate maps to show where large crowds gather, allowing the government to send emergency personnel to public protest venues.

Portable Hand-held GPS Jammer

According to Chen Derong, professor of wireless communications at Beijing University of Posts and Telecommunications, the mobile tracking system is not designed to monitor traffic. He said traffic monitoring does not require tracking the activities of individual people. “We are discussing two completely different ideas. The positioning of the mobile phone is a matter of personal privacy. If you want to understand this flow of traffic, you have to install cameras at the intersections,” he said of it. “Why shouldn’t they know personal information like my current location to avoid traffic jams or the like? Traffic and location tracking is as inappropriate as putting a horse’s mouth on its head of a bull. ” Criticism The author also claimed that the plan to follow up on all activities of the people of Beijing was a response to a large-scale protest in China in 2011, which was successfully mobilized via social media. According to a New York Times report, the protest was aimed at making people shout: “We want food, we want jobs, we want homes and we want fairness,” calling on people to take concrete action to try jazz. Take advantage of people’s dissatisfaction with inflation and rising house prices.

This occasion, along with the continuing domestic unrest caused by the rapid spread of large-scale protests in Middle Eastern countries, has led to unrest within the Chinese government. Authorities arrested the activists and placed more than 80 people under house arrest. Since then, others have disappeared. The follow-up plan was provided by the Beijing Municipal Science and Technology Commission, and officials avoided mentioning the system’s use as a law enforcement tool. Li Guoguang, an official with the Municipal Science and Technology Commission, said the plan “will provide information on the distribution and movement of urban populations with incredible precision.” It is assumed that the program was created in cooperation with China Mobile, a mobile phone provider in cooperation with the Chinese government. Li calculated that 70% of Beijing’s citizens carry cell phones, allowing their government to track all activities of 17 million people with great accuracy. Therefore, if you live in Beijing or plan to visit and use a local mobile phone, you may want to consider keeping your location private. To make it a reality, you can use a cell phone jammer to prevent the Beijing government from tracking your smartphone, so it should always maintain the privacy of the location.

InfiniDome has secured a $ 1.6 million investment to protect your GPS from hacker attacks

With vehicles becoming increasingly reliant on GPS systems, it seems pretty scary that a simple store-bought GPS jammer could interfere with your next trip on the highway. Fear not, InfiniDome has developed a simple and efficient solution to keep your GPS on track …

InfiniDome, an Israeli startup, aims to protect vehicles connected to GPS from basic nuisance and spoofing attacks. The cyber security firm must smell the financial potential as it just announced the opening of its Pre-Series A round, despite just closing a recently completed $ 1.6 million seed funding round raised by Next Gear Ventures of Israel, Boundary Holding, and Aston Partners of New York.

Pocket Mini GPS Jammer

Redefine GPS protection
Did you know that for just over $ 30 you can jam a GPS broadcast from a vehicle 30 feet away? It’s not just your car, this security system is critical to the safe functioning of drones, autonomous cars, connected fleets and critical infrastructure. To alleviate this fear, InfiniDome has developed a compact, efficient, and inexpensive device to protect GPS-connected systems from various jammers and spoofers. Based on Null-Steering, a spatial signal processing technique that eliminates all interference in wireless communication, the cyber device enables complete protection of all systems connected to GPS while weakening the hacker’s ability to block or interfere with the signal.

Speaking to Geektime, co-founder and CEO, Omer Sharar said that they have implemented the same principles of electronic warfare within the company that were previously strictly limited to military companies. “Instead of using just one antenna, we’re actually using a few. Combined with proprietary electronics and an algorithm, the system can detect which vector is attacking the vehicle and, by combining it with a received pattern, we can weaken the jammer’s signal. “Comparing InfiniDome’s technology with noise-canceling headphones, Sharar says,” If you’re listening to normal headphones, loud noise can easily drown out the music. ” Headphones with active noise canceling functions can reduce outside noise so you can enjoy your music. This is very similar to what our product offers – the hacker’s interference signal is weakened so that the GPS system can still connect to the satellite. ”

The cyber security startup recently launched OtoSphere, which can be easily connected to commercial and private vehicles. This innovative product is perfect for semi-trailers and Brink carrier vehicles, both of which are heavily targeted towards theft and rely on the monitoring of GPS transmitters at all times.

The latest round of financing will enable the company to further expand its global sales and marketing activities. The company employs 11 people across offices in New York and Caesarea. InfiniDome was founded in 2015 by Omer Sharar, Ehud Sharar and Moshe Kaplan.

Not the only “Infini” closures

Investments simply flew everywhere, the company name begins with “Infini”. As an Israeli-American data storage company, Infinidat has secured another round of investments led by existing investors, Goldman Sachs, ION Crossover Partners, TPG Growth, Claridge Israel and company founder Moshe Yanai. Infinidat developed data storage software that is easily adaptable to any purpose to optimize performance for all media types – present and future. The company’s enterprise data storage solution supports the workload while saving power, cooling and space costs. The Unicorn company’s final round of funding came in 2017 when the company received a $ 95 million investment based on an estimated value of $ 1.7 billion.

What is a GPS jammer? Are GPS jammers generally used in cars?

The GPS signal jamming system is designed to suppress the signal of the global satellite navigation GPS system in the range of 1500-1600MHz. The jammer makes it impossible for GPS satellites to monitor the location of cars and all vehicles through GPS, and the GPS jammer device will not interfere with mobile phones and other devices. Gps jammers can range from 5 to 15 meters, which is sufficient for cars and trucks and buses, because the tracker is usually installed in the cab inside the car. After starting the connection through the car cigarette lighter, the device immediately starts to work and generates radio noise (interference) in the range of 1500-1600 MHz (L1/L2) within a 15-meter radius.

handheld gps signal jammer

GPS equipment will need a phone card. The current location information calculated by the GPS module is uploaded from the communication base station to the positioning server through this card for users to query, and the jammer uses wireless electromagnetic waves to interfere with the communication between the card and the communication base station to achieve The purpose of GPS location cannot be queried by the user.

Working principle of GPS jammer:

Mainly by releasing radio interference waves, the GPS locator can be invalidated within the designated electromagnetic wave band, forming the same electromagnetic environment as the equipment used to block the signal.

There are two ways to shield GPS signals. First: The direct is to remove the two wires of the GPS host. Second: Go to the electronics market to buy a GPS signal jammer, but you must first distinguish what signal tracking method the GPS on your car uses.

There are only two ways of signal tracking: (1) Cell phone signal. (2) Direct satellite tracking signal.

Generally, most GPS tracking signals use mobile phone signals. GPS jammers have the same interference effect on car navigation. GPS used for car navigation is the same as mobile phone signals. It is easily interfered by electronic devices. The signals are shielded, so that all communication devices in the range lose their signals. However, such equipment also has disadvantages for the users. The signal jammer can only be turned on temporarily, and it is impossible to open it forever. As long as he turns off the jammer, the GPS will have the signal again.

Signal interference in teaching area during teaching management

With the increasing popularity of mobile phones, the status quo of students using mobile phones has even reached a large number of elementary school students, and the proportion of middle schools and high schools is even greater. At present, although various schools have clearly stipulated that teachers are not allowed to receive and call mobile phones during class, and students are also required to turn off their mobile phones or adjust their mobile phones to vibrate by themselves, but due to students’ self-discipline and self-consciousness, they have been giving schools daily teaching The management brings constant trouble! such as:

There will always be some students who forget to turn their mobile phones to vibrate for some reason, and a sudden call or text message during normal class, especially when some funny and tricky sounds sound, the originally quiet class and normal teaching will be interrupted.

Some students who are unconscious in class have the function of text messaging on their mobile phones. If they don’t want to attend class during class, they don’t need to whisper to the next desk to chat, just send and receive text messages on their phones.

Today’s mobile phones are equipped with Internet access, and students can frequently use their mobile phones to chat, read novels, and play games during class.

The school installs and uses the cell phone signal jammer device intelligent management system to prevent students from using their mobile phones excessively during class. However, when the mobile phone signal is shielded in the classroom, some students will say that the school violates the student’s “right to freedom of communication”. From the standpoint of students who frequently use mobile phones, these views seem reasonable, but if you think about it more seriously, if blocking the mobile phone signal infringes the students’ communication rights, then these students use mobile phones in classrooms or self-study. Have you ever thought that you violated the right of other students to receive education? Have you ever thought about respecting the teacher’s teaching authority? Whether right or freedom, there are only relatives, not absolutes. Any rights or freedoms are based on respect for the rights of others. The laws of our country are also rules based on the interests of most people. This rule protects the rights of most people. If you really want to talk about infringement, it is that a small number of students who use mobile phones freely regardless of occasion infringed on the education rights of most students.

Powerful signal jammer device

Some students or their parents may also suggest that the school has blocked mobile phone signals during class. What if there is something urgent in the family to contact or fail to notify the students themselves? In fact, this question is not difficult to answer. First of all, from the perspective of students, the reason why students use their mobile phones is to make contact with their parents convenient. In fact, students are in school, as long as there is no emergency, they don’t need to be on 24 hours a day. In case of special circumstances, the school, the teacher and the parents will take the initiative to contact. Secondly, from the perspective of parents, just remember that since their children were equipped with mobile phones, there have been a few times so far because of special circumstances. If they had to make a phone call, they would immediately stop learning in class and leave school to deal with it. of?

Moreover, the school has installed the campus mobile phone shielding device intelligent management system. It does not shield students from their mobile phones for all the 24 hours in the school. It only shields students for 40 to 50 minutes in the morning and afternoon classes. Shielding, even the ten-minute break between classes will restore the cell phone signal. The mobile phone jammer intelligent management system has fully considered the humanized shielding of students’ mobile phone signals.

What kind of signal jammer is good for the conference room

As we all know, the conference room is a very serious place and cannot be affected by the external environment. For example, corporate strategy meetings, public institution department meetings, public security, prosecutorial and judicial department meetings and other government department meetings. The progress of the meeting has a great impact. At this time, a mobile phone signal jammer is needed, and a mobile phone signal jammer is arranged in the meeting room to shield the mobile phone signal. The mobile phone has no signal and naturally cannot communicate with the outside world.

Desktop high-power electronic jammer

But how to choose a cell phone signal jammer device, Shenzhou Mingda company provides you with high-quality mobile phone signal shielding solutions:

1. According to the size of the meeting room. For example, the model of shielding device used in a meeting room of 100 square meters and 200 square meters is completely different.

2. According to the usage time of mobile phone signal jammer in the meeting room. According to our conventional understanding, if the frequency and time of use of the signal jammer is 5 hours a week, commercial machines can be used at a relatively low price. If the signal jammer is used for more than 20 hours a week, use an industrial machine, which is relatively expensive.

3. According to the intensity of the field signal used by the signal jammer. In the category of conference rooms, it is not easy to judge. We usually judge based on the absence of signal amplifiers in the office, whether there is an operator base station within 300 meters, and the signal strength of the usual mobile phone. If the mobile phone signal is strong, you need to use it. A slightly larger power shield.

In short, the purpose of the mobile phone signal jammer to shield the mobile phone signal is a comprehensive factor, including the consideration factors listed above.

Good reasons for using cell phone jammers in cinemas and theaters

Usually, when entering a movie theater or theater, turning off the phone is the most basic ceremony. However, in any case, some people will ignore these rituals and rules. Yes, when you watch a movie, you are always interrupted.

Try to convince people to observe the most basic social considerations in the movie. If you have visited a theater recently, you know they are often overlooked, so other methods have been explored to enforce theater ethics.

For new and popular movies, the theater may have a separate auditorium to block cell phone use, but the auditorium does not block the signal. This is more like the tradition of non-smoking areas in restaurants. Although the use of mobile phones is still discouraged in closed auditoriums, those who choose to watch movies will have to deal with occasional distractions.

Why use a cell phone jammer?

Hollywood film blogger Alex Billington (Alex Billington) is one of many people who rejoice in the rapid retreat of AMC. “Texting in the theater completely ruined the movie,” he said. “This is something we must fight on the social and cultural level.”

In 2014, a dispute between two men texting at a cinema in Florida eventually led to a fatal shooting. Although this is an extreme situation, most people would agree that the illuminated cell phone screen and finger taps can be annoying.

Phone calls are not just a hassle for movie theaters. When Benedict Cumberbatch played Hamlet in Barbican, he finally added a monologue, lamenting the tragedy of cell phone cameras and urging his fans to put down their phones. Some performers take the problem of disruptive technology completely in their own hands.

Have these people never participated in a movie so fully, or felt so deeply involved in a story that when something sounds or shakes or lights up a few seats, they don’t feel a momentary resentment, Smashed this spell? The problem started with a lack of respect for seat partners, or lack of respect for the entertainment media itself?

Of course, the reality is that all of these are important. In an era when we are forever consumed by our personal technology, the theater can and should be our last public refuge, and we can only be affected in movies and films. If that vision comes from a nostalgic or naive place, then this place is still a space for all of us, sitting proudly and provocatively in the dark.

Personally, I think theaters should be allowed to install cell phone signal jammer and there are clear signs that they are being used. If people don’t like this, they are free to spend money elsewhere. If all theaters eventually use the technology, then these people can choose not to go to the movies.

USS Boxer used electronic interference to take out Iranian drones, Pentagon sources say amphibious assault ship

The USS Boxer deployed electronic measures to dismantle a drone the US says was operated by the Iranian military, according to Pentagon sources familiar with the situation. The Navy says the drone was wrecked on the Strait of Hormuz on Thursday after it approached the ship and repeated warnings went unheeded.

Iran has denied the US claims, stating that all of its drones will be considered – and that the US ship may have accidentally shot down one of its own military drones.

U.S. Department of Defense officials, who were not empowered to speak publicly, said the drone was one of several threats to the boxer as he drove through the narrow waterway near the Iranian coast. It is said that at least one Iranian helicopter and several fast boats drove towards the ship on Thursday morning. The actions prompted the boxer to send a helicopter, which then flew side by side with the Iranian plane to repel him.

The boats eventually followed radio warnings to break contact, but the drone headed for the boxer instead of turning, the sources say. His presence was seen as a potential threat to flight operations aboard the amphibious assault ship, which carries a number of helicopters, as well as Osprey tiltrotor aircraft and a handful of fighter jets.

There were also concerns that the drone could pose a direct threat: in recent months, Iran-backed Houthi rebels have been using drones to drop explosives on targets in both Yemen and Saudi Arabia. According to a Pentagon source, the drone was unarmed in Thursday’s encounter.

The first US statements about the incident with the boxer did not contain any detailed information about the crash of the drone. On Friday, a Pentagon official clarified that the boxer was using electronic jammer measures to turn off the drone. The officer did not provide details in order not to disclose information about the ship’s capabilities.

wireless signal blocker

The news site Military.com states that a new Marine Corps anti-drone system was responsible for the Iranian drone crash, although the military did not confirm the report. USNI News notes that the Navy previously announced that the Marines were operating the jamming system on the deck of a US ship. USNI News described the weapon as one of a new series of “non-kinetic systems” that can cause a drone to crash.

President Trump first announced the crash on Thursday afternoon, saying “The drone was destroyed immediately” after closing within about 1,000 meters of the boxer and ignoring the request to resign.

Shortly after Trump’s testimony, Pentagon spokesman Jonathan Hoffman gave further details, saying a drone approached the Navy ship at around 10 a.m. local time while the ship was in international waters and on an “inbound road transit” von Hormuz “sailed. “”

However, on Friday, Trump said the U.S. ship shot down the drone, contradicting Pentagon officials’ report that the boxer was using jamming features. “No doubt no,” Trump said in the Oval Office, according to a White House pool report. He added, “We shot it down.”

When asked if he was concerned about the possibility of a major clash with Iran in the Strait of Hormuz, the pool report quoted Trump as saying, “No, not at all. … We hope they don’t do anything stupid about them. ” When they do that, they pay a price no one has ever paid before. ”

Also on Friday, a senior Trump administration official said the U.S. government had evidence that the boxer destroyed the drone and said more information about the shutdown would come from the Pentagon.

“We have very clear evidence, the Department of Defense issued its statement on the boxer’s actions,” the official told reporters on Friday. “The Iranians don’t have a great story with the truth. We are very confident in the president’s announcement.”

When asked if the Trump administration would take further action against Iran, the official said the US was ready to defend itself.

“It was your drone that approached our ship,” said the officer, adding, “If you keep doing this. If you fly too close to our ships, you will be shot down.”

US military officials say Iranian helicopters and drones often flew near US ships as they crossed the Strait of Hormuz between the Persian Gulf and the Gulf of Oman.

In an incident that began in August 2017, according to these officials, a US ship was harassed by an Iranian drone that flew near the ship during night operations. No shots were fired, but the encounter was classified as “clearly unsafe”.
