1. What is a GPS jammer?

The GPS signal jamming system is designed to suppress the signals of the satellite navigation GPS system in the 1500-1600MHz range. The screen prevents GPS satellites from detecting all positions and positions of the vehicle through GPS, and the GPS jammer equipment will not interfere with mobile phones and other equipment. The GPS jammer range can be from 5 to 15 meters, which is enough to reach vehicles and buses, as the trackers are usually installed in the cab of the vehicle. After the mechanical equipment is connected according to the vehicle borrowing device, it immediately starts working and generates wireless noise (interference) in the range of 1500-1600mHz (L1/L2) within a radius of 15 meters.

Second, there are various types of GPS jammers.

1. For GPS positioning and navigation system, you only need a GPS jammer.

2. Dual-mode navigation: Internet precise positioning (mobile phone data signal precise positioning) navigation + GPS navigation. For this kind of navigation, you need GSMGPS Jammer.

3. Internet precise positioning (mobile phone data signal precise positioning) navigation. So you need a gsm jammer.

4.COMPASS system software, GLONASS system and Galileo system software.

234 These three systems are rarely used for civilian purposes.

3. Car GPS Jammer

GPS devices will all need a number card. The location information calculated by the GPS module is submitted to the mobile phone positioning server by the base station through this card for users to view. The jammer uses wireless radio waves to interfere with this card. The communication between the card and the communication base station ensures that the location of the GPS cannot be viewed by users.

4. Principle of GPS jammer:

Mainly by emitting wireless interference electromagnetic waves, it can invalidate the GPS locator within a specific radio band, creating the same magnetic induction environment as the device to achieve the purpose of blocking signals. Two ways to block GPS signals. 1: Immediately disconnect the two cables of the GPS server. Second: Go to the Electronic City to buy a GPS signal jammer, but you must first understand what signal tracking method the GPS in your car uses. There are only two methods of signal tracking: (1) Cell phone signal. (2) Immediate communication satellite tracking data signal.

Generally, most GPS tracking signals use mobile phone signals. GPS jammers also have an interference effect on vehicle navigation. The GPS used for vehicle navigation is the same as mobile phone signals and is easily affected by electronic interference. The signal The jammer can block all signals in a certain area, causing any communication equipment within the range to lose signals. However, such equipment also has disadvantages for the person who uses it. The signal jammer can only be turned on temporarily and cannot be turned on all the time for use. As long as he turns off the jammer, the GPS signal will be available again.

Today, I will talk to you about whether signal jammers can effectively shield 5G network signals? This topic discussion will help everyone have a more comprehensive understanding of signal jammers. Below is a summary of some professional knowledge about signal jammers.

1. In addition to the 5G Internet signals that have been popularized at this stage, the commonly used Internet signals in mobile communications technology include the 3G network signals that became popular in the past two years, and the 2G network signals used by some elderly mobile phones. Although 5G network signals have become a concept discussed by many people now, it will take some time before 5G Internet is widespread.

2. First of all, it is clear that cell phone signal jammers can block 5G Internet signals. The mobile phone works within a certain frequency range. The mobile phone and the communication base station are connected through electromagnetic waves, and the data and sound are transmitted at a certain serial port baud rate and deployment method. For this kind of communication principle, the cell phone signal jammer transmits the low-end frequency of the wireless channel to the high-end scanner at a certain rate during the working process. This scanning rate can cause error code interference in the packet signal received by the mobile phone. The mobile phone cannot detect any normal data sent from the base station, making it impossible for the mobile phone to establish a connection with the base station. Mobile phones are mainly characterized by conditions such as searching the Internet, no signal, and no security system.

3. Regarding the shielding of 5G Internet signals, the key is to look at the frequency of the support point of the selected signal jammer. The current 5G frequency range is very wide, from 800M-2. 5G, if you want to shield the 5G signal, it depends on the frequency you use. How much network bandwidth can the jammer support? Because some 5G frequency bands almost overlap with WIFI 2.4. Once you block the 5G signal, WIFI and Bluetooth in the blocked area may not work properly. Therefore, whether the 5G signal can be blocked first depends on the function of the jammer product, and whether the device has a 5G signal shielding control module.

GPS locators have long been an indispensable fixture, whether determined as property in the course of business, or part of a home. However, the increasing use of these devices by consumers has given hackers more reasons to tamper with the system. Obviously, all potential interference with the way such a device operates will greatly undermine its performance.

GPS monitoring systems are primarily used for real-time location tracking, for monitoring property and family. For many years, monitoring devices have been used to carry out legal missions, including rescue missions, monitoring sex offenders, or monitoring criminals on bail. In addition, it can also be used to accurately locate and protect fleets. The device helps fleet managers to protect their vehicles and, in the event of theft of a person's property, ensures quick recovery, giving the company the opportunity to receive lower insurance premiums. In fact, these tracking devices have been used to check the whereabouts of their partners in order to catch potential cheating behavior.

For this reason, of course everyone has to deal with GPS interference to ensure that their equipment is always working properly. However, the irony is that GPS monitoring systems can potentially harm your own safety as much as it does your security. GPS jammers can be very effective if terrorists can get hold of key locations of government assets, or even if a wife tries to catch her cheating husband.

GPS Jamming Devices and Other Signal Control Devices

The various methods of jamming or interrupting GPS signals will also depend on the type of surveillance device used. The most direct way to avoid being tracked is to destroy the GPS device and make it inoperative. But if the intention is to secretly falsify it without the knowledge of the installer, then it is very easy to block or weaken the transmission of the tracking device by using these devices:

1. Metal shield

This is also a cheaper option. Simply enclose the tracking device with any metal covering, such as brass mesh or lead film shield. It is reported that the wizard uses refrigerated trucks to transport cars equipped with GPS search equipment to avoid being found.

2. GPS Jammer

GPS jammers are mainly sold online. Plug it into a 12v adapter in your car and it will now destroy the GPS signal in a certain area.

3. Cell Phone Signal Jammer

This device is a cell phone jammer, which means it prevents cell phone use. If an automatic tracking device is used, this jammer will prevent the wireless tracker from pushing real-time location updates.

Use high-power 5G jammers to achieve high power gain in the room

There are many online shopping malls selling signal jammers, such as cell phone signal jammers, GPS mobile phone signal callback functions, Wi-Fi signal blockers, UHF signal jammers, and other types of signal blockers. But now we rarely find a full-featured signal blocker that can block 5G signals and is suitable for indoor use, with strong sound spacing. If you need to get this kind of signal blocker, you can come here and get one you like.

Since many 5G cell phone signal blockers can block 5G mobile phone signals, of course we can't see the details of the high-power 5G jammers used in all rooms. The best way is to take an example and then look at the details of the 3G4G5GWimax signal callback function used in this room. Its full name is "70W high-power 3G4G5GWimax mobile phone signal".

Soon you will know that this high-power signal blocker design has 5 antennas and this high-power jammer design is dedicated to blocking CDMAGSMDCS/PCS3G4G5GWimax signals, so that the mobile phone signals in these frequency bands can be blocked and lose the function of sending and receiving information, so that this indoor 3G4GWimax signal callback can play the role of a security tool. In addition, due to the high power of 70W, the shielding radius of the jammer can reach 100 meters, which actually depends on the reception sensitivity in the given area of ​​the omnidirectional antenna design, which is very strong and can meet the current requirements.

With high power, this 5GWimax mobile phone signal jammer design has a good thermal conductivity system, which can easily achieve the goal of 24/7 continuous operation provided by the AC adapter, so that people who need it can easily achieve their goals by using indoor 3G4G5GWimax signal callback. In addition, adjustable buttons have also been used in this room, so this high-power adjustable 3G4G5GWimax mobile phone jammer allows users to decide the interference distance and interference radius according to their actual situation.

There are three categories of GPS jammers:

(1). GPS jammer, which blocks satellite signals (which, in turn, creates noise in communication satellite frequencies). The signal is always transmitted to equipment located on the road (or above) at two key frequencies: the GPS frequency (civilian L1 frequency band used to locate trackers) is 1575.42MHz. Frequency GLONASS (civilian L1 frequency band, used to locate trackers): 1602MHz. Because the frequencies are so close, they are blocked by broadband network noise generators, requiring only a wireless antenna.

(2) GSM jammer, which will have an impact on communication operators. Operators work under different rates, which actually lies in the mode (3G, 4G) and standard (GSM, DAMPS, CDMA). This way, many wireless antennas can be combined onto a single blocking device, thus shutting down all the wireless antennas so they can be separated.

(3) Universal jammer. It applies to all frequency bands, such as communication operators and satellite signals. It has several wireless antennas used to create an impact within a selected area. It also often gives the possibility of selective operation, that is, the ability to generate noise only at selected times (such as only the scope of the cellular radio module GSM1800).

When the GPS device was established, it was particularly popular among militants and government agencies. As everyone knows, GPS has become more and more widely used in daily life. In addition, GPS can protect the safety of your family and friends by tracking their real-time location and marking it on a personal map. Therefore, parents can search their children's parts anytime and anywhere. The production process of some processing plants is realized based on GPS equipment. However, GPS applications also have negative aspects. Warlocks and other criminals use GPS to carry out illegal activities: tracking other people's body parts without their permission.

If you feel like someone is tracking your location, we've got you covered with tools like GPS jammers. You can also record every minute of your personal session and mark your locations. Therefore, when you want to ensure that you and your personal privacy are protected, a GPS jammer is what you need. Using this device, no "adversary" can harm your privacy.

GPS blocker is specially designed to prohibit the use of GPS to block data signals. The jammer can be used to block various GPS tracking devices and block satellite tracking communications. It should be noted that the GPS jammer will not affect the mobile phone signal. This type of obstruction is particularly easy to put on because it is small and lightweight. In addition, you can also use an external rechargeable battery as a switching power supply or vehicle switching power supply.

In such a modern society, the use of GPS and mobile phone signal tracking devices has become a common presence in our daily lives. In order to protect your life and privacy and avoid being tracked by GPS and mobile phone signal tracking systems, the ideal way to deal with this phenomenon is to have these facilities to lock its capabilities. This wireless 3 antenna 5 stock band portable GPS mobile phone jammer is the good product you are looking for.

With the improvement of our living standards, most people are more and more concerned about their lives and privacy. With more and more signal tracking devices entering the modern world, we must take action to compete with these tracking devices. This GPS mobile phone jammer can help you and can become a good helper. In order to enjoy a better quality of life, all types of jammers are an indispensable part of life. We should use jammers to protect our privacy and keep our lives from the influence of such a modern society.

First of all, this handheld GPS cell phone signal jammer has a strong jamming ability, with 3 antennas, but can block 5 frequency bands. The purpose is to block GPS and CDMA GSM DCPCS signals at the same time. The 10-meter shadow radius is based on the reception sensitivity of the given area.

This mini handheld mobile and GPS jammer is not only enough to block cell phone signals, but also GPS signals. Therefore, you can also enjoy a quiet life, and at the same time, you can enjoy a high-quality life without being tracked by others. This jammer can also protect my family and friends. More importantly, with the mini portable design, you can freely use the mini compact design. This cell phone and GPS signal jammer provides more convenience for our daily life. You can also send it to any place you need. You can also use it at any time. In addition, this 5-frequency band portable jammer can also create a quiet environment for you at the same time. Just use it, and the mobile phone will lose the function of sending text messages and making calls in a distance.

In modern society, cell phone signal blockers are often used in large and medium-sized examination halls, and are also widely used in gas stations, financial institutions, hospitals and national defense areas. As long as there is a sign prohibiting the use of cell phones, there is generally a cell phone signal blocker. So how should you use the cell phone signal blocker? What is the basic principle of the cell phone signal blocker?

When using the cell phone signal blocker, select the area where the cell phone signal needs to be disconnected, and put the disconnector on the local desktop or wall. After the installation is successful, connect it, disconnect the power supply, and immediately turn on the main power switch. After the device is connected, press and hold the main power switch to disconnect the appliance and it can work. At this time, all cell phones on the scene will be in a network search state and will lose the signal of the communication base station. The cell phone is specifically manifested as searching the network, no signal, only service system, etc. Even the calling member cannot establish a normal voice call, give full play to its role, and complete the cell phone signal blocker.

For paper application methods, it can be used. cell phone signals are within a certain frequency range. After the cell phone and the communication base station are connected by electromagnetic waves, data and sound are transmitted in a specified serial port baud rate and in a coordinated manner. If the cell phone is blocked, you will not be able to make normal calls.

When using cell phone shielding, it is best to purchase some professional cell phone signal shielding equipment. Professional hardware configuration cannot be achieved by some simple systems. In areas where the magnetic field or electromagnetic field is abnormal, it will have a certain effect on the cell phone signal. The built-in cell phone flight mode in the cell phone is also a convenient cell phone signal method for users to reach some places where cell phone signals are not allowed to be generated.

In the past two years, various types of cell phone signal blockers have been varied, which makes people dizzy and overwhelmed. However, not all products are suitable for people to use. Some products are common, so they are not suitable for people to use in other industries. There is a very special blocker, which also appears in front of people. It is called wireless signal blocker. So what are the advantages of this kind of product?

When we use wireless signal blockers, you will find that no matter where we are, as long as we can turn on such a blocker, no one can find our network signal. In other words, household products are more effective than general public products. In such an environment, we can easily block all data signals. However, if we use a public type of blocker, you may also have the problem of unstable shielding effect. Therefore, we need to understand the actual application effect.

What are the advantages of wireless signal jammers? The following are the four major advantages of wireless signal jammers:

1. Wide application occasions

Wireless signal jammers are mainly used in examination venues, but not limited to examination venues. They can also be used in prisons, gas stations, to prevent mobile bombs, petrochemical plants, gas stations, detention centers, interrogation rooms, people's courts, labor camps, conference rooms, cinemas, churches, libraries, school dormitories, special security and confidentiality places (customs offices, reception halls, mobile vehicles, mobile political and business dignitaries protection sites), etc.

2. Strong purpose

Wireless signal jammers can be mainly used in the national college entrance examination, domestic postgraduate entrance examination, adult examination, self-study examination and various college examinations, as well as various junior high schools, vocational high schools, vocational high schools, prisons, detention centers, conference rooms, etc., to prevent the negative effects caused by cheating with cell phones, sending text messages indiscriminately, communicating with people outside the prison, collusion, etc.

3. Shielded signals are diverse

Effectively shield GSM/CDMA/DCS/PHS/TD-SCDMA/WCDMA/WIFI/TD-LTE/FDD-LTE.

4. Model advantages

1. Adopt high heat dissipation aluminum alloy housing, low operating temperature, and more stable shielding effect.

2. Built-in silent fan, low noise during operation.

3. Independent adapter. 12V/24V DC power supply system operation, convenient for vehicle-mounted mobile operation.

4. The external antenna design, unified one-end socket makes the appearance more beautiful and appropriate. And it has an anti-drop transmission design, and the antenna and the server have a marking working frequency band for easy one-to-one correspondence.

The rapid development of smart phone Wi-Fi networks has a great effect on improving the speed of development. Mobile phones can solve network problems. Mobile phones play a more important role in our daily lives, mobile communications and mobile Internet. In other aspects . It is because of this that it creates many problems, especially in the Internet, children are addicted to Internet technology, mainly because of Wi-Fi Internet. However, many people are slowly starting to install Wi-Fi jammer devices to block the Internet in order to control the baby's time.

Although Wi-Fi networks make it easier for everyone to browse Internet technology, the problems it brings cannot be ignored. This is not only a problem of wandering on the Internet, but also a problem of Internet security. In order to maintain a healthy network space, many areas have begun to install such desktop Wi-Fi jammers to maintain network information security in some areas and avoid excessive use of the Internet. This type of mechanical equipment has been widely used in countries and regions around the world, namely in universities, factories, public libraries, libraries and gas filling stations.

The use of Wi-Fi blockers is essential. On the one hand, it ensures the security of the Internet. On the other hand, it can also control the space for children to use the Internet, so as not to indulge in the fantasy world, which is very serious and harmful to their physical and mental health. Wi-Fi transmitter radiation can harm people's physical and mental health and is not suitable for long-term use. You can turn on the WiFi jammer to block WiFi.

The mobile phone security signal jammer only functions for mobile phone communications and has no impact on other electronic products. It is harmless to the body and can be widely used.

1 Various conference halls, auditoriums, courts, public libraries, examination rooms, schools, cinemas, and hospitals;

2 Gas filling stations, gas filling stations, oil and gas fields, and petrochemical plants;

3 Government departments, national defense, finance, securities, prisons, public security agencies or command systems are all places where the use of mobile phones is strictly prohibited.

2.2 Features

1Bochuang Guangguang brand mobile phone security signal jammer is entirely composed of brand-new SMD components and integrated circuit chips. It has excellent performance, is easy to install and use, and can continue to work for a long time.

2 The production process strictly follows the ISO9001 quality management system, and the work is stable and reliable. It is an ideal and trustworthy network security product that improves network information security, ensures production safety and protects the ecological environment.

Implicitly leaving all the isolators activated for a long time is not conducive to environmental protection, energy saving, environmental protection, equipment maintenance, and shortening the service life of the equipment (such as industrial areas, canteens, warehouses, etc., when no one is around at night, etc.) There is no need to turn on the cell phone jammer in these places 24 hours a day);

In order to facilitate customers to use signal jammers, this article will summarize some possible reasons why the signal jammer you purchased does not work properly.

1. You must buy the right jammer according to your needs, which is more important!

(1) If you want to block mobile Internet access, you must choose a 2G3G4G5G full-frequency signal jammer. At this time, you must consider whether to add additional functions such as GPS (navigation positioning) or WIFI (wireless access)!

(2) Choose a suitable power supply: portable jammers have low power and are easy to heat up, while desktop all-in-one jammers have high power and good heat dissipation! The shielding range of desktop all-in-one jammers is farther!

(3) If you want to block GPS tracks, you need to choose a two-in-one jammer (cheap 2GGPS jammer) at least! Because when you only use a mini GPS jammer to block GPS, it will automatically activate GPRSGSM positioning through the embedded SIM card.

2. After receiving the portable jammer with a battery (desktop all-in-one jammer without battery), it must be fully charged within 6-10 hours;

3. All antennas must be installed according to the label (1-12-23-34-45-56-67-78-8 or GSM to GSMGPS to GPS.......). More importantly, do not turn on the jammer without installing the antenna!

4. Affected range: location reception sensitivity <=-75dBm. The affected distance will vary according to the reception sensitivity and location. If you are close to the signal base station, the actual effect of the jammer will be very poor!

Schools should follow these three standards when applying signal jammers:

1. The application of signal jammer cannot be obtained by giving up the cost of mass mobile communication technology.

Among the people who use cell phone signal jammers, some do it to avoid cheating in exams, and some do it to keep the venue quiet or keep the conference confidential. These are all out of good wishes and purposes. But there are also reasons for self-interest. For example, a homeowner who operates a public phone booth is very likely to use a jammer to affect the mobile communication signal towers near his operation site, so that people working near the public phone booth he operates can use their mobile phones. It is not easy to use, so it is changed to a public telephone booth to make calls to increase its own economic benefits. In addition, the three major mobile operators are also likely to use jammers to harm the rights and interests of each other, so that they can gain an advantage in the competition among peers in some departments. In addition, cell phone signal jammers are also very easy to be added to mobile phone software and turned into a veritable monitoring device.

The above examples are the purposes for which we use mobile phone signal jammers, but no matter what the purpose is, it should not be obtained at the cost of giving up mass mobile communication technology. In fact, based on scientific research, it is possible to install a mobile phone signal jammer without affecting the normal use of mass mobile communications. There are three reasons why cell phone signal jammers disrupt mobile signal tower signals:

First, the user of the mobile phone signal jammer did not pay attention to the communication needs of the Smiling Man at all, and the function target was wrong. It should have limited the mobile phone communication of a small group of people (such as students), but expanded the target to other nearby general groups.

Second, the operation method is unreasonable. Because the installation position of the cell phone signal jammer is unreasonable or its signal strength setting is too large, it should be operated within a small range but is not operated well.

Third, the purchased mobile phone signal jammer does not comply with the wireless communication equipment approval standards, the output power exceeds the standard, or is a shoddy and substandard product. Choosing the right reason, in order to avoid its impact on mobile communication signals, is actually very simple: first, use qualified products produced by reliable manufacturers, and secondly, choose the installation location and function direction well. , The third is to set an appropriate signal strength and limit the transmitted signal to a small, closed range. As long as the above three points are ensured, the damage to surrounding mobile communication signal towers can be reduced to a minimum level.

2. Improper use of mobile phone signal jammers in schools may cause unnecessary damage to the body.

Theoretical analysis shows that when the mobile phone signal jammer is working, if the setting is unreasonable and the signal strength is too high, in a small closed space such as a conference hall or a classroom, the radio waves will be lost in the narrow space. Accumulatively, through multiple reflection surfaces from walls, ceilings, and roads that are originally separated from the outside, people in the room will be exposed to severe electromagnetic radiation. According to the survey, the college entrance examination, junior high school and high school are the places where mobile phone signal jammers are most used. However, in some examination rooms where cell phone signal jammers are used, some defendants (college entrance examination inspection staff, students and teachers) become upset and lose energy. Due to the concentration of law and other situations, some students even suffer from headaches. Many signs indicate that if the signal strength of the cell phone signal jammer is turned on too high, it will seriously affect the normal thinking of students in the examination room.

As we all know, the characteristics of electromagnetic waves spreading freely in the air. While cell phone signal jammers can achieve their limited purpose of blocking mobile signal tower signals in a special area, they can also harm human health to varying degrees. , so use cell phone signal jammers with caution.

3. Responsibility management methods Units should increase the scope of control and standards

In response to the increasing use of mobile phone signal jammers by people from all walks of life, departments such as the wireless communication management and security bureau must increase the scope of control and standardize the use of mobile phone signal jammers.
