When you want to buy a GPS jammer, you may have a certain understanding of its function, that is, interfering with GPS signals, which can prevent GPS tracking. Here we will explain it in detail.
Before explaining the GPS jammer itself, it is best to explain how GPS works. GPS represents the Global Positioning System, a system used by individuals, business entities and the military, primarily for navigational purposes.
The GPS Global Positioning System uses a series of Earth orbit satellites that transmit radio signals. The signal arrives at the GPS receiver to determine the positioning by triangulation. GPS can be found in single handheld devices and cellular phones, vehicle navigation and positioning systems, and small GPS tracking devices.
By triangulation, a way of measuring three individual points to calculate the position,the position can be found.In the car's navigation system, the vehicle's position is measured by three satellites around. With triangulation, GPS can transfer the position to the receiver with an accuracy of only inch.
The GPS signal is a radio signal using a specific frequency. GPS actually has two main frequencies, one of which is for public, non-military (1575.42 MHz), and the other for the US military (1227.6 MHz). Since GPS is only weak radio waves, these waves may be jammed or twisted by using GPS jammers.
GPS jammers were originally created by governments, military organizations and spy agencies. Its applications include confusing the enemy in the exact location, or where the enemy GPS missile or bomb will fall.
Now civilians have been looking for these devices to protect their privacy in the ever-increasing GPS tracking world. There are several civilian uses to block GPS signals that are primarily related to privacy, including the ability to hide themselves or vehicles in case they are tracked by GPS receivers. A practical application is for salesman or the driver, who may wish to eat lunch outside their territory, or go home to get an item without having to do a lot of explanation for the GPS tracking on their vehicle. Most civilian GPS jammers are enough to cover even the largest vehicles that can protect users' privacy.
If you want to protect your privacy,you can buy jammers here.
Now, some phone fraud is very common, the means of fraud are various and endless. There are many injuries received, the most of which are students and seniors.
Most students are lack of social experience and not sensible, sot the liars utilize students' information disclosure to do scams. Many young students are cheated because of that. Not long ago, a student died because of cheating and morbidity.From which we see the importance of information protection. The information is too easy to leak on the Internet, so, in some cases, we may need a wireless jammer to help protect the information.
For the elderly, many liars utilize their concern for the children and their unfamiliarity of modern technology, to cheat them. The liars will deceive the elderly to go to the bank and transfer money through the phone . Bank of Tokyo has begun to install gsm jammers in strategic ATM locations in the region in order to reduce the transfer of older people due to mobile fraud. This is to respond to the elderly as the target of the liar, ask them to go to the bank, and from the ATM to take out a child in need of money, while staying online, by telephone to deceive these elderly transfer. These devices are said to be low power, covering only about 2 meters of area.
To fight a liar, everyone is responsible. In order to deal with telephone fraud, first of all, we should pay attention to the protection of privacy, especially the protection of personal information, and secondly, be careful of the crook trick.
Some people may want to buy jammers, but they are not sure whether the jammer can meet their own requirements, or interfere with the equipment they want to block. What device can the jammer interfere with? Here we talk about that.
Signal jammers are electronic devices that are intended to block different frequency bands according to their specifications. These specifications may include many different frequencies that the jammer will be successfully block.
So, the key to determine whether the jammer can interfere with the device you want is to see whether the device's work requires signal transmission or not.
Such as mobile phone jammers can interfere with the phone calls, this is because the phone calls need signal transmission, including GSM, 3G, 4G. It is important to know that the phone calls in different places are different. Therefore, we should choose the cell phone jammer that can block the exact local phone signals.
In addition to mobile phone jammers (corresponding to GSM, 3G, 4G signals), there are GPS jammers that can block GPS signals. They can interfere with GPS tracker, GPS navigator and so on. Similarly, Bluetooth, WiFi jammer interference with wlan signal, the corresponding block the WiFi devices, such as wireless networks. UHF / VHF bands (including LoJack), and satellite XM radio jammers can interfere with the devices which use these signal.
So if you want to use WiFi Bluetooth signal jammers, keep in mind that your own wireless internet will also be blocked. And do not forget the satellite signal of the TV, because sometimes this exclusive interference may affect it if the frequency is the same.
And some devices such as fixed phones, they will not be affected by any signal interference, because it use line. So even if you use the GSM / 3G blocker, your fixed phone will be fine.
All in all, jammers can interfere with the devices that mainly need signal transmission when working. So, before selecting the jammer, please confirm the signal you want to interfere with and select the jammer corresponding to the signal, so as to meet your requirements.
Have you considered buying a jammer, but do not understand it? Most people have heard of cell phone jammer, know its function, but not deeply understanding, and even do not understand the specifications of jammers , and don't know how to choose a good jammer. Now we have to explain the specifications of the jammer, so that you can know it better.
First of all, the band frequency is a critical part of the jammer specification. Because the jammer work by affecting the frequency band to destroy the network signal. The most complex is the mobile phone frequency band, because different countries use different phone bands, and there are 2g, 3g and 4g respectively. Here, you only need to know GSM for digital cellular, the 900 MHz and 1800 MHz bands in Europe and Asia, and in the US 800MHz and 1900 MHz bands.
Take the 60501 Portable Whole Mobile Phone WiFi Signal Jammer for example, the frequency band is:
LTE4G,700
725-775MHz
CDMA800
851-894MHz
GSM1900
1920-1990MHz
3G
2110-2170 MHz
WiFi,2.4Ghz
2400-2500 MHz
GPSL1
1570-1580 MHz
This means that it can affect the range of frequency bands. If you still feel puzzled, do not worry, just tell us your country, we will automatically match your local use of the band.
Effective radius range
The effective radius range is the interference distance that can be used with the jammer. The actual interference distance will vary depending on the signal strength and the use position as well as the full charge.
Total output power
The total output power is the actual power (watts) of the radio frequency energy generated by the jammer at its output. The bigger the total output power, the farther the interference range, the better the effect.
Antenna
An antenna is a dedicated transducer that converts a radio frequency field into an exchange or vice versa. Each jamming device has several antennas to send signals. The more the antenna, the stronger the blocking signal. For some devices, the antenna is built in. The jammer is divided into directional and omnidirectional . Most jammers are omnidirectional. Before deciding on what you choose, you need to know the number of each antenna.
Hope that the above explanation can help you understand the specifications of the jammers and help you choose the phone jammers better.
Now the cell phones have been widely used, even a 3 years old child can use the phone. So when you see the students in the school to play phone and other electronic products,you should not be surprised. This is because the family wants to contact their children easily, or give the phone to the children as an entertainment tool. But there is no doubt that children are easily obsessed with the phone that has caused the attention of the world.
As minors, their minds are not yet ripe and are more susceptible to temptations, especially addicted to phone games. Because of neglect of discipline, many children indulge in the phone. For those who are obsessed with the phone, they are more likely to waste the time when they should learn. In class, they will secretly hold a cell phone and chat with their friends or play mobile games. Extracurricular, some students no longer exercise or participate in outdoor activities. They do their own thing with a cell phone. These have seriously affected the child's learning and health.
How to deal with this situation?
For parents, they should control the time of the children's using mobile phones and other electronic products, the most important thing is to develop children's interest.
And it is controversial for schools to allow students to bring smartphones and electronics into school, and whether they can install wireless jammers at school to prevent students from secretly using their mobile phones. We know that there are many schools are forbidden students with mobile phones, but this is not convenient for parents.And some students can secretly take a cell phone,and the school can not find out. At the same time, the teacher is limited, and can not manage every student. So is it time to consider using mobile phone jammers?
More importantly, more and more students are using smart phones and electronic products in the exam cheating. Because they do not listen carefully to teachers in the classroom, they spend too much time playing smart phones and electronic products, rather than doing homework and learning tests. To pass the exam, some of them have no choice but turn to cheating. Smartphones are the best tool for searching for information and interrelated. As a result, smartphones and electronics are the recipients of students' cheating.
So the jammers can become a way of prohibiting students from using the phone. But some people worry about how to do when face an emergency situation, and how to contact with parents. In response to this, managers should discuss about it and consider the law. But there is no doubt that if gsm jammers are used normally, they can of course help teachers and students.
More and more people are increasingly concerned that their privacy would be leaked, and consciously protect their privacy. We all know that there are many ways and tools to silently steal our personal information, and even unknowingly.
We use different smart devices every day, such as GPS navigators, laptops, smartphones and so on. These devices give us a lot of convenience, but there is no doubt that your personal information is also leaked from these devices. You can say that your wireless gadget is the double agent of the stolen person.
We use Wi-Fi connection, but we do not know that it can be easily hacked. We use Bluetooth, we have never heard of Bluetooth hacker technology. When we use GPS to determine where we are and how we get where we need, we find there may be gps tracking.
From these aspects, it is not difficult to understand why these gsm jammers are so popular in the world . This is because people want to protect their privacy.
But why jammers are illegal in many countries, because their use may affect other agencies, such as gps jammers may disrupt others' gps navigation. So when we use jammers to protect our privacy, we should not forget the rights of others. The jammer should be used appropriately.
This is the advice we give for you to use jammers appropriately:
Do not use jamming devices in public places. We recommend that you use blockers in a private location. Try not to open it in public places, because you may violate the rights of others. You are free to use jammers in your car or at home. Also, choose a signal blocker with the proper working range you need to avoid interfering with someone else.
We have the right to defend our privacy, but we should not violate others' right. You should remember that other people want to communicate freely. Try not to block them. Because there may be an urgent call.
Find the frequency you need to interfere with and select jammers with appropriate working range. Here you can find what you want.
Nowadays almost no one does not know what Bluetooth is. Like any other technology, Bluetooth is actually under development, there are many ways to block the Bluetooth signal.
What is bluetooth?
Bluetooth is a low-power wireless connectivity technology used to stream audio, transfer data and broadcast information between devices. There are two flavors of Bluetooth technology, Basic Rate/Enhanced Data Rate (BR/EDR) and Low Energy (LE).Thus, basically this type of frequency is very good for data transmission between two devices.
And why a person needs to stop this useful function. Many people are transferring files via Bluetooth.The files transmission is forbidden is some places like the company secret files.And this technology works at the frequency of 2.4GHz, which is similar to the wireless networks.And the wireless network can be utilized by the hackers to steal your confidential informations.
So in some cases,if you want to stop the so-called Bluetooth, then you should know how to do it - the easiest way is with the help of a bluetooth jammer.And it is very easy to find online.To find the signal jammer fulfill your needs,please note that where you intend to use the jammer and how long you plan to use.It is very important because they decide what jammer do you need.
Now everyone has at least one computer. Over the past decade, the use of the Internet has increased significantly. WiFi network has been greatly popular, most people have installed WiFi network at home.
There is no doubt that the WiFi network has brought us a lot of convenience, so that we can easily access the Internet. We know that what makes WiFi can be widely used is the router. They are great gadgets because the internet can spread all over your place. You only need to set them, the password on the home network on it. You can connect as many computers as possible to the network. Of course, sometimes you can only connect a limited number of devices up to 5 or 10 devices.
When people go to some places such as restaurants, cafes, etc, they may ask whether there are WiFi.They have been accustomed to the WiFi network, and with WiFi, many people will be used to play mobile phone and ignore the people who can communicate around. Maybe you are one of those who hate these things, you need to relax a little, forget all those annoying wireless networks and busy people, need to have time to communicate with people. Or do you just care about the information available on the wireless network? So lucky, you can deal with this problem with the help of a gadget which called wlan jammer. WiFi jammers can be stored in your pocket or installed somewhere in your home (depending on your current choice - desktop or portable).
In addition, if you want to limit the use of WiFi time at home, you can also use WiFi jammers. It can be used to prevent children from overriding using cell phones and WiFi networks.
These Wi-Fi interceptors are actually running very simply, and it sends the same frequency signal as WiFi to interfere with WiFi signals. You only need to be sure that you know the correct frequency type used here. In this case, it is 2.4 GHz.
There are more good news - Bluetooth is running at the same frequency. This means that you will not only be able to block wireless connections, but also prevent Bluetooth.
We know that cell phone jammers have been around for a long time. As we have already mentioned at the beginning, the mobile jammers were mainly used in police and military applications. In the military, jammers are used to block the enemy's communication. The police can use jammers to block the communication of criminals and prevent terrorist attacks, such as some signal-controlled bombs.
Now, the jammer has been applied to more and more people in city. Some organizations, such as schools, use jammers to prevent cheating, companies use jammers to prevent the use of mobile phones, and some factories to protect the confidentiality of informations.
In addition, personal use of jammers also have a lot, even more. Many people feel strange, personal use of mobile phone jammers to do? Why do people need to get those that are actually quite expensive to block the equipment, or even illegal? But it is not difficult to understand that everyone has the right to protect his privacy, and now the phone tracking too easy, the information on the phone is not difficult to leak. Then you need to prepare the tool to prevent this. There is also a lot of people who are trying to really modernize and can not stop talking on their mobile devices.
So the solution to the above problems. A simple and effective way to do this is to use a cell phone jammer. It is not difficult to understand why there are many people want to use the jammer cause.
But we have to take into account the negative situation. This is where these blocking devices are illegal in most countries. You can guess why. After all, you may prevent someone from making an emergency call to the police or the hospital. That is why we recommend buying the local law before buying a gsm jammer, and do not affect the reasons for others. On the other hand, if you think no one knows you are interfering with the signal, you can always buy the phone signal from the Internet. If you have any questions and needs, you can contact us.
Nowadays, wireless technology is a very important part of our lives. Mobile phones, radios, WiFi, navigator, etc. are applied to wireless technology. One of the most prominent examples of such widely used wireless technologies is GPS.
Now GPS has been widely used, we went to an unfamiliar place, the first use is the GPS navigation, so you can easily find the destination, Making travel route planning will also use GPS navigation.There is no doubt that GPS navigation and our lives are inseparable. This may be the main reason why GPS signal blockers are considered illegal. They are dangerous because they may destroy important communications.
However, if one day GPS can not be used, or GPS can be improper used, such as illegal tracking. It is well known that putting all the eggs in a basket is very dangerous, so there are some alternatives to the GPS navigation system. They are GLONASS, unit tower triangulation and Wi-Fi navigation. GLONASS is very clear to the public, it is like a similar GPS in Russia, and unit tower triangulation and Wi-Fi navigation may need to explain.
We started from Wi-Fi navigation. The system is under development, but the first step is made by Google. Google has collected information about thousands of Wi-Fi hotspots in the Street View project, which can be used for navigation. As long as the physical location of these wireless hotspots is fixed, the position between at least three locations can be calculated. Use the signal strength to calculate the distance of each hot spot, the closer the hot spot, the stronger the signal. The future may be widely used. But it also has two shortcomings: compared with the GPS, its results are not accurate.And it can only be used in densely populated areas where there are a large number of Wi-Fi hotspots. It is hoped that the accuracy of this technology will grow as the number of Wi-Fi networks grows.
The second technology is the mobile phone base station triangulation, which is more convenient because it uses your own phone to track your location. You may know that your phone is connected to at least 2-3 base stations. Their coordinates are known and fixed. And your location is calculated between the three unit towers. The benefits of this technique are: it can be used universally, because almost everyone has a cell phone that can be found by phone signals, even indoors.
Here you can see some tracking technology without GPS signal, but it also means that there are many ways to track people. In this case, it is advisable to use a common multi-frequency jammer when you are not sure how others track you.
