What needs do we need GPS jammers to meet?

Since the GPS system has been installed in place, it is of great help to us. Based on the GPS system, we have developed many devices to help us carry out military use and life. But the GPS system also poses a very dangerous threat to us, it can easily reveal our location. Anyone can easily find our location by putting a small GPS device in our car or even pocket. In order to protect ourselves from the danger of illegal tracking, we need GPS jammers. GPS jammer is an anti-GPS electronic device, which can transmit a stronger signal to cover the GPS signal with the same frequency as the GPS signal. Since this signal from the GPS jammer is stronger than the GPS signal, it may cover and hide the GPS signal, so that all GPS devices in a certain area cannot receive the GPS signal and therefore cannot work normally.

GPS jammers are becoming more and more popular

As GPS systems become more and more popular, GPS signal jammers have become necessary for us. You may want to know what GPS jammers are and what potential applications they have. In order to explain the GPS jammer, we first need to know how the GPS system works. Global Positioning System—GPS for short, is a system used by many people, companies and military for navigation purposes. The GPS system uses a series of satellites that emit radio signals. Such signals reach the electronic GPS receiver to determine the position by triangulating the shape. GPS can be used for personal portable electronic devices, vehicle navigation and positioning systems, and can also be used for small GPS tracking devices. The position of a person can be found by triangulation, which is a method of measuring three separate points to calculate the position. In the GPS system of the vehicle, the position of the car is measured by three satellites orbiting the earth. GPS can accurately transmit location information to the receiver through triangulation.

Let us now look at GPS signals, which are radio signals occupying specific frequencies. GPS actually has two main frequencies, one is for public and non-military use, and the other is only for the US military. Since GPS is nothing more than weak radio waves, although technical equipment and expertise are required for this purpose, GPS jammers can be used to block or distort these waves.

GPS jammers were originally created by the government for military organizations and spy agencies. Some themes can be combined with cell phone jammers (also called cell phone jammers and wifi jammers). Uses include messing up the enemy at exact locations, or making enemy GPS guided missiles or bombs fall in these places.

Recently, civilians have sought these devices to ensure their privacy in a world increasingly tracked by GPS. However, most civilians do not have the technical ability to create their own devices because it is much more complicated than blocking radio signals through basic radio interference.

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

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

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

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

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

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

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

Can the test signal blocker block all communication signals?

Can the test signal jammer shield all communication signals? Speaking of which, many people are unfamiliar with the test signal jammer device. In fact, it has been widely used in the college entrance examination examination room. In the college entrance examination last year, many examination rooms installed this kind of equipment. The response has been very good, and it has been proven to have a good effect on preventing electronic signal cheating. Starting this year, it has been vigorously promoted so that more examination rooms can also install shields.

Nowadays, the emergence of shielding device has solved many hidden dangers of disrupting the order in the examination room, so that candidates can take the exam in a fair environment. The principle of this kind of test signal jammer is actually to isolate the electronic signal to make the communication signal of the mobile phone fail, which can prevent the phenomenon of using mobile phones to cheat. Not only that, it also has a good shielding effect for the WIFI2.4G signal. Say that the effective range is within a radius of 0 to 30 meters, generally a low-power test signal jammer is enough to cover an entire classroom, which meets the needs of the test room for shielding signals, and because the endurance of this equipment is generally three Although the heat dissipation is poor, it also leads to a particularly high price/performance ratio. It is especially suitable for schools to purchase signal shielding for examination rooms. Many customers have troubles about the purchase of test signal jammers. At this time, you can contact greatjammer to inquire about the price of test signal jammers. It is a manufacturer with many years of high-quality and rich experience in the development of jammers.

What is the difference between the experimental data and the actual data of the test signal jammer?

What is the difference between the experimental data and the actual data of the test signal jammer device? Now that the college entrance examination season is approaching, the examination rooms of major schools are getting busy because they have to make preparations in advance for the arrangement of the examination rooms, and they have to purchase a batch of equipment in advance. This is the test signal shield. This kind of equipment that can effectively prevent electronic signal cheating in the college entrance examination is also a very popular method in major examinations. We all know that its effective range is differentiated according to the size of the power, and this data is generally purchased It is written on the instruction manual when the equipment comes back. At this time, new questions will arise. How much is the difference between the experimental data of the test signal shield and the actual data?

Desktop 5g jammer

To answer this question, you must first know what is called experimental data. The meaning of experimental data is that the test signal shield is in an open environment, and there are no base stations and other things that affect the magnetic strength within 500 meters. The shielding range produced ; What about the actual data? This is very clear, because when the test signal jammer is actually put into use, it is not clear how far the base station is from the test room, or whether there is a need to penetrate walls, so in general, the actual data of the jammer It needs to be actually put into use to know. Now when choosing an exam signal jammer, you must choose a professional one, and a professional machine must be provided by a professional manufacturer. Among them, Gteatjammer is a professional manufacturer with many years of experience in the research and development of exam signal jammers. Its product quality experience is strictly quality inspection. Each product is trustworthy, and it has gained the trust and affirmation of many customers. It is a wise choice worth buying.

How to prevent eavesdropping in the car?

The ever-changing technology also makes it easier to expose people’s privacy to the public’s vision. Recently, a small gsm eavesdropping on the market is very popular. It is understood that many buyers install this type of eavesdropping device in the car. Many people also responded to our colleagues that they were afraid that their private conversations would be eavesdropped. This kind of eavesdropping equipment can be installed in a very hidden place and is not easy to be found. Even many professional anti-eavesdropping equipment cannot be detected. What is it? The reason?

It is understood that this gsm bug is only the size of a coin. It can be placed in the car, or it can be attached to a certain place on the car using a magnetic device. What is more, it can be placed in a place that is difficult for people to detect (such as the instrument In the built-in electrical equipment), the driver’s conversation information can be recorded unconsciously. Of course, the eavesdropper may also receive a car battery or a large-capacity battery for continuous GSM tracker. On the other hand, this makes the threat more persistent and keeps the privacy of the eavesdropped being stolen. This GSM bug can be placed in a hidden place in the office or at home, such as under the desk or built-in in household electronic devices such as alarm clocks, TVs, and chargers. It is very hidden. The power supply under the table may be cut off and may be unintentionally discovered, but it is not only difficult to be detected when it is built into an electrical appliance, but it can also be directly used for indefinite long-term work. Illegal tracking of vehicles, eavesdropping of conversations in vehicles, and eavesdropping of private households are illegal acts and a great threat to personal privacy, and should be paid attention to.

Why is this kind of eavesdropper so difficult to detect? Because it is an analog mobile phone signal, it is mixed in many mobile phone signals, and it is not easy to detect. Even if some professional detection equipment is not operated by someone who is very familiar with wireless signals, it may be No results are found. When the eavesdropper dials the phone card number in the eavesdropper in a remote place, the eavesdropper starts to work, and the surrounding sounds are transmitted to the eavesdropper through the mobile phone signal. Tracking and positioning. It is always threatening people’s normal work and life.

For such a very concealed eavesdropping device, should it be located and swept away? The following is a practical anti-eavesdropping GSM jammer recommended by the security experts of Shenzhou Mingda, because the working principle of gsm eavesdropping device is similar to that of mobile phones, so The mobile phone detector can well detect the source of such gsm bugs, so as to find the eavesdropping equipment, remove hidden dangers, and completely eliminate the threat of eavesdropping and tracking. It can find hidden mobile phones in the environment (turn on or off, even without batteries). It is a short-range mobile phone scanner, which is different from traditional metal detectors: it can detect the common material of all mobile phones, not just for metal, which can reduce false alarms for other metal materials, such as watches , Keys, coins, belt buckles, etc. This anti-eavesdropping detector is very easy to use. It can quickly complete environmental security detection and find hidden mobile phones in time (even if they are covered by metal or packages can be detected). The device is easy to operate, with LCD interface display, and 9V battery power supply, which is convenient to carry. It can help car owners to detect eavesdropping on their cars.

New anti-drone guns impose order in the sky

In recent years, drones have become a rare pastime for amateurs. Now drones are everywhere, from people taking selfies, to commercial photography, to search and rescue missions.

Because of its ubiquity, accidents started to happen. The sky has become a drone infestation, and laws must be enacted to maintain order in the air, mainly in cities and airports. Due to their number and ability to carry all kinds of luggage, they have also become a serious threat to security expert review.

As mentioned earlier, it is not uncommon for drones to almost collide with aircraft, and drones equipped with cameras (or worse, explosives) may pose unique threats to the safety of the ground and facilities. However, in most cases, there are not many safe methods to deal with them.

Now, a new device that looks like a weapon in science fiction uses electromagnetic signals to knock drones out of the air quickly and safely.

drone jammer gun high power

Drone jammer guns are described as providing “safety countermeasures against various drone models.” It allows controlled management of UAV payloads (such as explosives) without causing damage to common UAV models or the surrounding environment. “This anti-drone device weighs about 8 kilograms and has an effective range of up to 1 km. It can be used on a rechargeable lithium-ion battery. As far as design is concerned, it will not be used by Stormtroopers in Star Wars movies.

It is very simple: you point the gun at the drone and pull the trigger. Transmit a series of electromagnetic signals and block the connection between the drone and its pilot. It uses radio frequencies to stop the drone from transmitting video and block the drone’s signal, forcing it to return to the launch point or land on the spot. “If the drone’s response is to go back to the beginning, this provides an opportunity to track it back to the operator.

Of course, there are other high-end technologies that can also attack aerial drones. It is an automatic defense strike system for drones.

The prison service has requested the installation of a signal jammer

Due to concerns about the ineffective jammers installed in the Rajasthan Central Prison and the use of cell phones by inmates, the State Prison Service asked the Home Office to transfer the total income of the three prisons from ‘worth Rs 2012 for best results.

Not only is the government struggling to restrict phone use, prison security is also affected. The High Court also takes these matters seriously. The prison official added in a letter to the government: “In order to prevent the prisoners from using the telephone and to better interfere, we ask you to approve the transfer of these 57 jammers to the two central prisons of Bikaner and Bharatpur. And “Ajmer”.

The prison department has requested a budget of Rs 7,200,100 for the transfer of the jammer, Rs. 1.12 million for the new tower, and Rs. 188 crore for the annual maintenance of the equipment.

As we all know, mobile phone signal jammers are very common. People will choose to buy mobile phone signal jammers to maintain their privacy and protect their independent space. Where will the jammers be used?

armband mobile gps jamming

Cell phone jammer is mainly used in various places where cell phone use is prohibited, such as various inspection rooms, schools, gas stations, churches, courts, libraries, conference centers, theaters, hospitals , governments, finances, prisons, public security and military might.

It is understandable that the WiFi cell phone signal jammers in the market can limit cell phone signals that are 500 meters from the transmitting station and have a radius of> 20 meters. The shielding radius is adjustable, it only protects the cellphone signal without affecting other electronic devices. Save energy, the power is 20W-480w.

The mobile phone is in a certain frequency range when it is operating. The mobile phone and the base station are connected by radio waves, and the data and sound transmission is supplemented by a certain baud rate and modulation method. Taking this communication principle into account, the mobile phone jammer will sweep the frequency from the low to the top of the front channel at a certain speed during the working process. The mobile phone seems to search the network, there is no signal, no service system and other phenomena.
The signal jammer is very convenient and practical, you don’t have to worry about whether it will be difficult to use.
