On the evening of December 19 local time, two unmanned aircraft were intercepted from London Gatwick Airport, causing the aircraft to close. At 9:00 pm local time, two industrial-quality drones were suddenly discovered at the airport, which interfered with the take-off and landing of the flight plane. Therefore, the airport closed the runway in time and reopened at 3:00 am on the 20th. After 45 minutes, the airport was again disturbed by drones, and the authorities subsequently announced the closure of the airport.

Airport Police Chief Bolton Shuo said that when the police searched for the drone controller, they disappeared every time they reached their destination. When the airport reopens, the drone will appear near the airport runway. Police analysts believe that this is a deliberate intervention in the airport incident. In order to prevent this serious situation from happening again, tools such as high-end drone jammer should be used to manipulate the drone, blocking and closing at certain frequencies. UAV signal.

UAV countermeasure market analysis

During this period of time, everyone knows that drone black-flying incidents happen frequently, small enough to be used for peeping, large enough to steal state secrets and military secrets, small enough to fall and injure a person, large enough to cause the airport to close. The delay of the aircraft and the stranded passengers have caused serious consequences. Therefore, the national laws have also been continuously improved during this period. Legal documents have been issued one by one to strengthen the control and real-name registration of drones. Here we do not make any comment on politics, only UAV defense and UAV countermeasures technical means are analyzed.

There are several ways to control drones:

1. This method of shooting with a gun seems to be more enjoyable. It not only manages but also destroys it. The damage index is higher than five stars. But there is a problem that is more headache. It requires the shooter to be accurate, not the one who has participated in the Olympics and won the championship. Forget it, so as not to be embarrassed. In addition, you need to find the right time. Once you fall, it is absolutely not allowed to hurt people. It is important to get off the phone. In addition, you must remember where you are calling. If you fall, you need to find it. This is a headache. The question, how many people do you need? Who flew the last question is unknown!

2. Catching with a net is similar to shooting a gun, except that the gun shoots out points, here is the net; it seems that this technology has improved, the destructive power is reduced, and the accuracy rate is improved, but the prerequisite for the problem is The drone needs to fly low, and the human station is high, so the practicability is low;

3. Drone jammer is also the mainstream technology at present. The remote control signal of UAV is blocked by high-power transmission, so that the UAV loses control. Generally, UAVs can be shot down directly, and smart UAVs can also be unmanned. Aircraft interference interferes with GPS and Beidou signals to prevent drones from returning home;

There are two types of UAV interference:

1) Hand-held UAV jammers require humans to conduct investigations, and it is found that manual intervention by the handheld UAV jammers can achieve the control effect; the control distance can generally reach about 2 kilometers;

2), base station type UAV jammer The base station type UAV jammer is mainly aimed at the relatively large control area, prevents the drone from entering the control area, and greatly reduces the safety risk; it can be completed without a large number of personnel operation; control Distance: 6-8 kilometers can be;

In addition, I did a lot of searches on the Internet. The Chinese characteristics are vividly reflected. As long as there is a need for thousands of troops to invest in this market, the market capacity and market opportunities are as big as everyone’s guess;

One set to two sets per unit, let’s calculate that the quantity is really limited and belongs to a niche market; in addition, the technical content is not particularly high, the threshold is low, the more participating businesses, the smaller the market profit margin, so it is recommended that those already on the road should be prepared Don’t be hot on the road for a while, look at the market sensibly.

GPS jammer in civilian areas

GPS jammer can easily be ordered from the Internet and have the ability to protect privacy and prevent third party tracking. These products are beneficial and should be bought. For example, some VIP characters can prevent illegal location using the GPS tracker.

In North America and Europe, of course, such equipment is also required to protect privacy. Because you don’t know when your vehicle is being followed by someone else. GPS trackers are easy to buy.

GPS jamming technology can also be used to manage drones. Professor Todd Humphreys and his team have taken control of an unmanned drone using GPS spoofing technology in Austin. They used tiny helicopters to disrupt GPS systems in unmanned aerial vehicles and then provide coordinates so drones can reach their destinations.

It’s not the first time that a drone’s vulnerability has been exposed. It’s easy to buy a GPS jammer on the internet and then crash a drone. And this signal interference is effective for all unmanned aircraft.

The famous Davos Economic Forum has used similar devices to regulate the use of drones to ensure order and security. Such devices have played an important role in the success of recent conferences.

At the moment, the military applications of GPS jammer technology are mainly focused on electronic warfare. For decades, one of the main requirements in electronic warfare has been to geographically hostile transmissions. This has resulted in a plethora of location-finding techniques such as receive signal strength (RSS), arrival angle (AOA), arrival time (TOA), arrival time difference (TDOA), frequency difference of arrival (FDOA) and so on.

In a positioning application, we have a mutual problem: instead of trying to localize a transmitter relative to ourselves, we try to localize ourselves relative to a number of transmitters. Of course we use the same techniques: GPS is an excellent example of a TOA system.

Russian electronic interference with the Finnish and Norwegian GPS networks began in early September 2017 and was classified as secret by the Norwegian authorities until the exact nature of the scenario was determined.

The loss of GPS capabilities from commercial aircraft could certainly have resulted in a catastrophic air disaster, but the Norwegian Intel believes that Russian GPS jamming over Finland / Norway was not the intention of the Russian government or the Russian military.

According to the expert analysis, GPS interference and interference mitigation technology will be the key points for future electronic warfare.

Measures against reconnaissance and intelligence radio interference

Smartphone radio wave blocking In the information age, communication technology for high-speed development, mobile phone has become an important and indispensable tool for people’s daily work and life. However, this brings various advantages.

The proliferation of mobile phones cannot be ignored. I’m creating some issues. Various problems are getting serious with mobile phones. The development of science and technology, mobile phone location tracking and surveillance has become the most important means of reconnaissance and intelligence sources in the world. Therefore, as long as you use it or not, it will be caused by a leak, in a voyeur detection machine, as long as you have a cell phone in a secret location, most likely a unit or individual, a country that also has serious harm to political parties.

All the latest patch elements and integrated circuits, such as cell phone signal jammer, advanced performance, easy installation, long time continuous operation. We have developed a deterrent device that can effectively deal with the problem of mobile phone signal jamming. Countermeasures against radio wave interference Security information such as electric fence networks, new products with specific electromagnetic signals at loci that should protect base stations so that mobile phones cannot receive data is transferred from the security roll to mobile phones. It is not possible to eliminate the negative effects generated by and establish a connection with the base station. Telephone signal jammer will be your loyal defender you can trust and provide a safe and quiet space!

Location of use: Prohibit the use of mobile phones in government, military, finance, securities, prisons, commercial vehicles gps countermeasures public safety command centers, or anywhere. Phone signal jammer has the effect for mobile communication only, without interfering with other harmless electronic devices, and can be widely applied.

Handy blocker keeps your location secret

If you have never used a jammer before, it is important to emphasize that this device should cut the signals from GPS devices. The gps signal jammer perfectly blocks the transmission of GPS signals and gps so that gps devices cannot recognize your specific location.

The type and model of GPS jammer have different technical specifications, so we recommend that you carefully study technical functions before buying. Each cell phone jammer has a different blocking radius, which is positive from 5 to 100 meters. Nearby GPS devices will work fine. Furthermore, GPS blockers are equipped with a rechargeable battery and when fully charged you can use it for a long time Use time without a stop.

adjustable gps jamming device

Also gps jammer can have different design, so you can choose portable or handheld gps jammer and desktop. To order, you have to decide whether you want to use it in one place or you will use it in different places, you can protect it to take all the time, then you have to buy portable GPS jammer. With the small size and light weight, you can take portable GPS blocker anywhere you go, which is very practical. What is more there is GPS signal blocker that can block several types of signals. Imagine a jammer can block gps signals, signals from mobile phones CDMA / GSM (860-970MHz), DCS / PHS (1805-1930MHz) and 3G signals (2110-2170MH).

Canadian high school principals try to use cell phone jammer

Principal Steve Gray of Port Hardy Secondary School on Vancouver Island, who bought the signal jammer from an online vendor in China, said he had to prove something since children were still using their phones despite the cell phone ban at school.

While the experiment was short-lived, the controversy speaks to the growing problem in schools, especially high schools, of the rampant use of cell phones during school hours.

Donnelly also notes that controlling devices is important because they can be a mechanism for everything from cyber bullying to passing responses to a test.

So the problem is not only educating children about the proper use of cell phones and other technological devices, but also about making sure parents understand the rules at their children’s school, she said.

Why use the gsm jammer?

“We note what we perceive as a growing negative impact of cell phone use on student learning and particularly on student engagement,” said Steve Gough, principal at Comstock Park High School. “Cell phones can be a powerful tool to help people access information, but they can also be a powerful distraction.”

College students are quite optimistic about using smartphones and laptops in class and believe that they can aid learning and are critical to their safety, so they should be left at all times. And when a cell phone rings in class, students prefer to be ignored by instructors, joyfully wielding it through humor, or talking to the student privately after class. In contrast, most of the interviewed US teachers had specific rules in their curricula for using all digital devices in class with penalties for rule violations2. Surprisingly popular were the outright bans on student phones and laptops.

Too many students use their cell phones to talk, visit, and verify what is taught in the classroom. We need to correct this now. Cell phones can be a great learning tool, but parents must set the law on how and when to use them.

Officials at the United States Department of State are still trying other ways to fix the cell phone problem. DOC is working with a Maryland-based company on a $ 1.5 million contract to install a system that “allows authorized calls to pass but blocks others in a precisely defined target area.” That system will be installed at the end of the month.

If cell phone jammer is not properly regulated, similar to bi-directional amplifiers (BDAs), we will experience a more severe uncontrollable disorder that has led the industry to pursue the overabundance of interfering signals emitted by FCC approved devices. It’s easy to inadvertently create a blocker. Rotate the gain control to the maximum on both the uplink and downlink amplifier and disregard the isolation between the redistribution antenna system and the donor. The level of white noise generated by this device is at least as damaging and dangerous to public safety radio systems as any interference device designed so far. Typically, BDAs are installed without proper supervision and maximum gain is used to provide the most coverage, while this two-way amplifier is unknowingly nothing more than a broadband generator radiating to an outside antenna.

The jammer must be used within the limits permitted by law

New interference signals with power supply – 12 power antennas can be adjusted to the 3G 4G mobile phone signal mini jammer WiFi GPS VHF UHF LOJACK RF signal blocker.

Good jammer 2G 3G 4G mobile phone, WIFI, GPS, invisible headset radio systems and bone conduction. It does not obstruct the target signal, there is no damage to the target and other electronic products. In short, it prohibits previously defined for frequency bands of a given signal: CDMA 869-894MHzGSM, GSM 925-960MHz, DCS 1805-1880MHz 1900-1990MHz, 3G 2010-2025 2110-2145MHz, 4G 2300-2380 2555- 2655MHz and so on. Turn off the power, signal interference / signal blocking will stop working, the whole area of target phone can immediately resume work.

mini drone jammer

It can also prevent the GPS from locating the GPS satellite. If the GPS tracker is hidden by thieves in our car, which is stupid and dangerous, we will object, otherwise we cannot guarantee our safety. The jammer signal / blocking signal in your car and make it work, it displays a false appearance of geolocation jammer tracker. For example, you are out of the garage, but the GPS tracker cannot receive satellite signals, and therefore compatible with the credit history. 12 The crossed antennas work in all its areas of work to compensate for the lack between them.

The new signal jammer can protect you well from the interference target and can meet your needs. Please note that this product is designed to protect user privacy, should not be used in criminal activities. So make sure that your activities are authorized by law, otherwise we will not be responsible for all your illegal behavior.

Turning off your phone can be a big help for your child’s growth

Mobile phones and Wifi jammer now generally use a directional antenna design, which can easily prevent CDMA, GSM, DCS, PCS, 3G and WiFi from moving in a certain direction, thereby blocking the direction of interference. , which is a 360-degree interference signal without dead angles.

There is an old saying: every family has problems and parents and children have always had problems. It seems that parents and children can never live in peace, as children are adolescents and their barriers to communication become obvious. This happens for many reasons. Especially with the advent of cell phones, parent-child communication has become less happy and more difficult. When they were young, they would rather play games on their smartphones than listen to your suggestions. This happens not only at home, but always at school. Students and teachers fell into a deep circle because of the phone. Now you need to come here for help with the GPS signal jammer.

Blocking the telephone signal is very useful. Your child came as a teenager. You know you are not allowed to order again. Therefore, please open your brain and buy this cell phone jammer, wifi will help you in secret. Once they use the phone to play games or do something time-wasting, don’t think about learning them, you can turn on the phone signal to interfere with the buttons. They will not be able to play the game and you will have the opportunity to speak to them face to face. Still at school, blocking cell phone signals can undermine cheating and continue to check. Look! Mobile phones and 5G jammers use a directional antenna design to easily prevent CDMA, GSM, DCS, PCS, 3G and WiFi from interfering in a certain direction and blocking the direction.

Your child wants to be independent and free from parental care. Adolescence refers to the growth of children. They are no longer children. They want to make their own decisions and make them rebellious. Parents tell them to do things. They do it to prove that they are adults. These WIFI signal jammers that block telephone signals can help you build a communication bridge.

Jammers of drones and quadrocopters

The digital revolution pervades all areas of our lives. Unmanned aerial vehicles (drones and quadrocopters) are gaining popularity and become more autonomous. It is becoming increasingly difficult to defend against unauthorized invasion of privacy. For example, it is very difficult to protect yourself from unauthorized aerial shots that can be carried out with the help of “drones”.

First, for the purpose of controlling unmanned aerial vehicles, 2.4-5.8 GHz WiFi communication was used. Now, radio frequencies of various ranges and even satellite communications are often used. Video equipment is installed on the drone, and it is capable of transmitting everything to the camera’s lens “to the base”. How do you like it if you don’t know who owns a drone or a quadrocopter will circle over your lawn? Or will someone use these devices to shoot a production facility that you own, with locations for hidden security posts and video surveillance systems? Are you ready to share your work secrets?

Drones in the hands of attackers can cause you real damage. Already no one can guarantee you privacy. However, there is one remedy. Devices that interfere with the transmission of audio and video signals – drone jammer. As drones improve, these devices also become more technically sophisticated and powerful enough to carry out the corresponding tasks.

Below we will give you some recommendations for choosing such a “jammer”. The main indicator of the effectiveness of such a device is the spectrum of blocked frequencies. The frequencies used by drones to transmit signals to a control station can be classified as follows:

frequency range for video transmission: 2.4G WIFI 2400-2500 MHz 20 W;
frequency range used for remote transmission of control commands: 2.4G WIFI 2400-2500 MHz 20 W;
frequency range for video signal transmission and remote transmission of radio control commands: 5.8G 5.5-5.9 MHz 2 W;
frequency range of remote transmission of radio control commands (868-912 MHz, 860-920 MHz 25 W, 433-434 MHz 20 W);
Additional GPS frequencies L1 1575 MHz 40 watts.

At the output, such a “signal jammer” is capable of delivering power up to 127 watts. Six 0.5-meter fiberglass whip antennas provide an effective 360-degree coverage area.

The effective range of the “jammer” is 200-800 meters. The impact power varies depending on the signal strength and the distance of the drone from the “base”. Reliable cooling system (built-in chillers: 5 small internal versions and 3 larger ones – from the top above) ensures a silent and reliable operation of the device. A peripheral network device (in the execution from 50 to 60 Hz, from 100 to 240 V AC (AC100-240 V-DC24-27 V) will be able to ensure the effective operation of your “drone suppressor” around the clock.

WiFi jammers have been used in various fields

From Antiquity to the present day, security has always been an important aspect to consider, like the army, the network, the network and many other areas. In this case, we need different types of security tools in all areas, and here you can get wifi jammer that can secure your network.

Today, computers have become an indispensable and important tool for people’s work and life. Just as people work at the same time, they always use computers to process others, share important information, and even communicate with people. Email to other countries. There are many other tools that facilitate communication, which all depend on the network and achieve their goals. Therefore, people should connect and achieve their goals. More and more people are using wireless routers because they can use the network more easily without having to connect a cable to a laptop or use phones and WiFi over the Internet.

If we look closely, we can see that in different places and different areas, various security measures have been taken to ensure a safe environment. For example, in factories, hotels, schools and many other places, we can usually see that in many places, building defenders have to register first. All of this is done to provide security, and in many important places you can see the situation more clearly. Then we can realize that security plays an important role in various domains and networks. Now the wifi jammer has become a dominant player in the market, and many people are slowly starting to accept this device.

Yes, this is very useful, but for prudent people, we sometimes find that using wifi and mobile phone interference signals can also cause them many problems. If they use this device, their important files may even be stolen. Even if they have set a password for their WiFi router, someone can hack it, then access and use your network, and if they do, they can steal your device without notifying you. You can only see the problem to find out what happened, and then take action to resolve the problem. This is why more and more people are even taking care of network security and using WiFi jammers as good assistants.

Our company provides various types of drone jammers

Our company offers a certain number of tools and technical instruments which make it possible to neutralize a drone by selectively blocking the control signals.

While UAV detection radars, UAV spectrum analyzers and UAV detection sensors are designed to provide timely advice on drone approach, the complete anti-drone system requires the use of devices to eliminate threats from drones entering protected areas.

Our company offers different models of drone jammer, which represent one of the most effective tools to deactivate drones by blocking control signals. Our systems can be equipped with drone jammers used to neutralize UAVs and jammers used to defeat explosive devices.

Drone jammers are used to block signals from drones and force them to land. They cancel the transfer of photo or video material from the drone to the operator and cause the drone to lose control if it carries dangerous substances. In other words, jamming systems provide the intentional emission of radio frequency signals to block UAVs in a particular area.

The jamming systems are controlled by special software which is used to selectively disrupt various command and control communication links used by UAVs and to choose the most appropriate means of responding to emerging threats while mitigating the collateral impact.
