GPS is a frequency range used by navigation satellites to track the location of land, water and aircraft with GPS tracking equipment installed. The GPS frequency range has five frequency bands, but only three frequency bands are available for civilian use-L1, L2 and L5. GPS is the most extensive tracking spectrum (developed and widely used in the United States). In this category, you will find several GPS jammers (anti-tracking devices) that will help you protect the privacy of your vehicle or any other place.

How to use high-power test room signal jammer

The test room high power jammer has become an indispensable tool in the test room, escorting the information security of the test room. However, if we do not use the equipment correctly, there will be poor results, or even an exam room accident.

1. The effective shielding range of the test room signal jammer will be different in different use sites. This is closely related to the signal field strength on site. The shielding range of mobile phones of different standards may not be the same at the same site;

2. The factors that affect the shielding range include but are not limited to: distance from the base station, orientation, obstacles, the wall material of the site building, the installation height of the shield, the installation specifications, etc.;

3. Each antenna has a frequency band identification, which must correspond to the frequency band identification on the host one-to-one. Before turning on the jammer, ensure that each antenna is connected reliably. It is never allowed to turn on the device without connecting the antenna;

4. The surface temperature of the shield is about 40～50℃ after working for a long time, which is normal. If the surface temperature is too high, please turn off the power and try to contact your local dealer or agent;

5. The normal installation height is 1.8 meters ~ 2.5 meters, try to choose a place where there are no obstacles between the target shielding area. The wall-mounted installation requires the antenna to face up vertically. When placed on a desktop, the antenna can be folded 90 degrees and then up vertically. There should be no AC power lines or other audio and video lines within 0.2 meters of the antenna;

6. During use, in order to avoid possible interference with some electronic equipment, try to keep it at least 1 to 2 meters away from the following common equipment: audio, wireless microphone, radio, computer, TV, Wi-Fi router, etc.

The above are the precautions when using the test room signal jammer introduced by Jammer-mart. I hope it can help everyone.

What are the main applications of anti-UAV systems

According to its product manual, the anti-UAV system allegedly uses signal jammer on 2.4 and 5.8 GHz frequencies. It also has technology that can block GPS and the Russian equivalent of GLONASS.

By the end of 2017, the long-range automatic anti-UAV system provided by Shenzhou Mingda can provide the detection range of a small drone like the DJI phantom, up to 5 kilometers, 360-degree panoramic coverage, no blind spots and visual tracking capabilities. Identify and eliminate drones up to 2 kilometers away. The system is composed of advanced military radar, advanced long-range EO/IR visible and thermal infrared day and night PTZ surveillance camera system and powerful broad-spectrum RF and GPS signal jammer. . This automated system will provide 24/7 detection, tracking and elimination of drones/unmanned aerial vehicles, with the option of static jammers for permanent installation, making it a high level of mobile, perimeter security, activities, airports, and rural and urban security Ideal choice for value goals. Threats up to 10 kilometers in diameter.

There are many systems that can be used to land willful or dangerous drones, but they often have a big gain: you need to be relatively close to the drone, which can be scary if the robot plane is loading explosives. It is launching a drone strike gun, a jammer that can disable drone signals (including GPS and GLONASS positioning) from 1.2 miles away. Like most competitors, it will not destroy the target drone-it simply forces the vehicle to land or return to its starting point. Anti-drone teams can not only disable threats from a safe distance, they can also locate their pilots.

The authorities have now begun field tests of their new anti-drone “gun”, which can shoot down any unpopular drone. The police used a new drone jammer in a recent large football match. Any drones that intrude into the competition venue are banned and forced to land via the signal interference capability of the system.

According to reports, the new jamming system is able to capture the target from a kilometer away, which gives it enough range to eliminate the incoming air threat before it arrives. The authorities are taking these types of threats seriously, which is why they may buy more units for different police agencies in the country.

Criminals complete the theft in 20 seconds

Recently, the border defense detachment of Dongguan City, Guangdong reported that a series of car property theft cases that occurred in service areas such as Guangzhou-Shenzhen Expressway Houjie this year have been solved. Criminal gangs used signal jammer to transmit signal interference, causing car owners to lock the car and steal the car. Inside property.

From the surveillance video, we can see that in the Dalingshan service area of the Guangzhou-Shenzhen Expressway, a man wearing a white short-sleeved T-shirt got off a black car. He seemed to be moving his muscles and bones. In fact, he was just pretending to rest and looking for the target of the crime. . Soon, a gray SUV drove into the service area and stopped. A man and a woman in the car closed the door and left.

At this time, the criminal suspect appeared again, and saw him approaching the SUV car casually, opened the door easily, quickly got something from the car, turned around and got into the corresponding vehicle and quickly escaped. The entire theft process took less than 20 seconds.

In the end, the Hunan suspect Tan and his associates were arrested by the police in a hotel in Dongguan at the end of September. In the face of hard evidence, Tan and his associates confessed to the crime.

How to deal with “car jammers”?

①When traveling or shopping for parking, try to choose a public parking lot with camera monitoring. Especially when parking overnight, try to park in a parking lot that is supervised by someone.

②When locking the car, pay attention to the phenomenon of locking the car. For example, when some cars are locked, the two rearview mirrors will be retracted; when some cars are locked, the turn signal will flash twice, etc. When an abnormal lock is found in the use of an electronic lock, a manual lock should be used to increase the safety factor and try to avoid unnecessary losses.

③When you lock the car, pay attention to whether there are suspicious people around. Before you leave the car, pull the car door with your hands to make sure it is locked.

④Don’t put valuables such as leather bags, mobile phones, cash, etc. in the car, so as not to let criminals catch them.

Can a mobile phone signal jammer in an examination room shield a classroom?

Important admissions exams, qualification exams or final exams need to install mobile phone signal jammers to shield the electronic signals around the exam room and prevent possible electronic cheating. So, how much area can the mobile phone signal jammer in the examination room shield? Can only one shielding device be used in an examination room for shielding purposes? How many jammers should be used in a teaching building?

First of all, we need to know: The cell phone jammer in the examination room has a theoretical shielding range, which is about a radius of 0-20 meters. But please note that this is a theoretical distance. The actual effect should be combined with the local signal strength, especially whether there is a signal base station nearby. If there is a signal base station within 200 meters, the shielding effect will be compromised. In addition, the wall will weaken the shielding effect of the shield. As the signal is stronger near the window, the shielding effect will be weakened.

arm gsm 3g gps phone jammer

The standard classrooms in schools are generally about 75 square meters, each classroom equipped with a shielding device can achieve better results. It can be placed in the middle of the classroom for maximum shielding. Of course, this must be determined in conjunction with the power supply wiring. It is also common to place the shield at the podium. If it is a larger classroom or there is a base station nearby, you can place two jammers in each classroom, one at the front and one at the front, and the shielding signal is superimposed and enhanced, and a better effect of 1+1>2 will be achieved. In addition, in order to ensure the shielding effect, another shield can be arranged every 10-20 meters in the aisle of the teaching building. Finally, it should be noted that the installation height of the shield is preferably 1.5-2 meters from the ground.

MDPB-5E (6 channels) upgraded mobile phone signal jammer is a mobile phone signal jammer specially developed and produced by adopting international advanced shielding technology to meet market demand. The equipment has undergone a brand-new upgrade, changing from 5 channels to 6 channels increases the shielding effect of the device itself on the signal.

The shielding effect is stronger, the performance is more stable, and it is easier to be recognized and accepted by customers.

MDPB-5E (6 channels) upgraded mobile phone signal jammer can automatically form a shielding magnetic field within the specified range when it enters the working state, forcibly disabling mobile phone signals, MDPB-5E (6 channels) upgraded mobile phone signal jammer only works Mobile phone communication signals are shielded without causing interference to other electronic devices, which has also become its rare advantage. The advent of the upgraded version of MDPB-5E (6 channels) mobile phone signal jammer may completely solve the harm to users caused by the information leakage of communication facilities, allowing people to enjoy the speed and convenience brought by high-tech to mankind while ensuring The security of its information.

MDPB-5E (6 channels) upgraded mobile phone signal jammerIts most important applications are in examination rooms, prisons, gas stations, mobile phone bomb prevention, oil depots, liquefied gas stations, detention centers, interrogation rooms, courts, labor reform teams, conference rooms, theaters , Churches, libraries, school dormitories, special security and confidential occasions (confidential offices, negotiation rooms, mobile vehicles, mobile politicians and business dignitaries guarding) scenes, etc., and mobile phone signal jammers are becoming more and more important in social life.

The anti-drone market has a bright future

Nowadays young people like to play with drones, because small drones can bring people unlimited fun, but some young people who have a shallow understanding of the law will use drones to spy on others’ privacy, thereby invading others Human rights. In order to be able to restrain and prohibit these young people from doing wrongdoing, the drone jammer was launched.

uav drone blocker

With the continuous progress of society and the increasingly moderate price of drones, more people will own drones in the future, so the intensity of the management of drones will increase, and it is inevitable that some people will not comply Laws, control drones flying everywhere. Or do not register the UAV to do some illegal things, then after the anti-drone system, these illegal things can be properly resolved, that is, interfere with the normal use of the UAV. Forcing the drone to land, thereby ensuring the safety of national airspace and the safety of social security.

In short, the prospects for the development of the anti-drone market are broad, so investors who want to invest may wish to get familiar with the rules as soon as possible to lay a solid foundation for future gains.

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.

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

What is a GPS jammer?

The GPS signal jamming system is designed to suppress the signals 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 jammer 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.

GPS jammers have that type

1. GPS positioning and navigation system, only need gps jammer.

2. Dual-mode navigation: network positioning (mobile phone signal positioning) navigation + GPS navigation. For this kind of navigation, you need a GSM GPS jammer.

3. Network positioning (mobile phone signal positioning) navigation. For this, you need a gsm jammer.

4. COMPASS system, GLONASS system and Galileo system.

234 These three systems are hardly used for civilian purposes.

car GPS 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.

the 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 to achieve the purpose of blocking 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.

Can a mobile phone signal jammer shield 4G signals?

Today, I will talk to you about whether the mobile phone signal jammer can effectively shield the 4G network signal? This topic will help everyone have a more comprehensive understanding of the signal jammer. Next, the editor summarized a few pieces of knowledge about mobile phone signal jammers.

1. In addition to the 4G network signals that have been widely used, the commonly used mobile communication network signals include the 3G network signals that were popular in the past few years, as well as the 2G network signals used by some elderly phones. Although 5G network signals have become a topic of discussion by many people, it will take some time before they can reach 5G networks.

2. The first thing to be clear is that the mobile phone signal jammer can shield 4G network signals. When the mobile phone is operating in a certain frequency range, the mobile phone and the base station are connected by radio waves, and the transmission of data and sound is completed with a certain baud rate and modulation method. Aiming at this communication principle, the mobile phone signal jammer scans from the low-end frequency of the forward channel to the high-end at a certain speed during operation. This scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data announced from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested in the phenomenon of searching the network, no signal, no service system, etc.

3. The key to shielding 4G network signals depends on the frequency supported by the selected mobile phone signal jammer. The current 4G frequency range is very wide, from 800M-2. 4G, if you want to shield 4G signals, it depends on what you use for shielding. How much bandwidth can the device support? Because some of the 4G frequency band almost overlaps with WIFI 2.4. Once you shield the 4G signal, the WIFI and Bluetooth in the shielded area may not work properly. Therefore, whether the 4G signal can be shielded depends on the function of the shielding product, whether the device has a 4G signal shielding module.

Jammers can prevent the transmission of negative emotions

The humming and noise of the phone in public places could cause negative emotions in others, this behavior is outrageous, especially in theaters, cinemas, restaurants, concert halls and speeches, etc. In order to avoid such a loud voice, a local GPS jammer installed at these locations, in particular 2G 3G 4G, GPS, WiFi, Bluetooth, LoJack jammer, is blocked.

adjustable gps jamming device

Speech is important to show whenever speakers hope to achieve their goals through individual performances. No one likes his speech brutally interrupted by some viewers of the phone, then he felt neglected and disrespectful – and sometimes beat your man is not your competitors, but the vandals. You are these attacked vandals, and worse still, the behavior seems to be understood and appreciated … it really starts, becoming a normal trend, it was to make a speech to the public, there is always a chance that they will suddenly drop out of other phones.

Therefore, we recommend that you install phone jammer before speaking. The equipment can be up to 10 meters, must calculate the area of the place, the device if the number of cell phone jammers. 10 antennas are switched to different interference objectives, as we mentioned in the first paragraph, or we can make them all work. This means that almost the phone can ring and work there (cannot receive and receive phone calls and text), you can use the source Wi-Fi signal, data can be transmitted via Bluetooth, no GPS signal and LoJack, no follow-up. In short, no mobile device can run speech, they can focus on performance and avoid interruptions.

In order to avoid loud noises in the voice telephone, you can better use the jammers.
