Mobile phones have become very useful. It has greatly facilitated our lives. At the same time, various personal information such as bank card account passwords, home addresses, facebook account passwords, company information data, etc. are stored in mobile phones Data security is very important. To protect the security of mobile phone information and prevent potential criminals from using some electronic technology tools to steal mobile phone secrets, it is recommended to use cell phone jammer products.

What are the differences between ordinary mobile phone signal jammers and high-quality signal jammers?

Signal jammer, generally speaking, can be divided into ordinary shielding and high-quality shielding.

Ordinary shielding, its technical characteristics are mainly based on shielding principles, using a large number of low-power or high-power devices to fight against, staying on simple technical solutions.

Anti-drone technology is necessary in the future

Anti-UAV technology, why is it essential for airports.

With the dramatic increase in drone penetration in the past few years, controlling the sky above us has become an additional responsibility. UAV detection solutions have become very important, not only can detect long-distance UAVs, but also access a variety of potentially important information, such as controller location and UAV model.

Who are those organizations that rely on drone detection? The police force certainly bears a great deal of responsibility when tracking illegal activities involving drones, but the airport (probably more than any other type of venue) must fully control the sky above its location. As drones increasingly enter the airspace around airports, this reality has become more relevant in recent times.

Last summer, a drone entered the airspace near Gatwick Airport, causing five aircraft to be diverted and completely closed the runway.

In addition to endangering the safety of passengers on board, taking up air traffic control time, and causing inconvenience to people who eventually misplace or put their journey on hold, it can be said with certainty that the interruption of drones will eventually cause great losses to airlines. All these problems are caused by a relatively small unmanned aerial vehicle, which emphasizes the importance of airport drone detection.

According to this BBC article, the British Airprox Commission conducted an investigation into the Gatwick incident and concluded that the incident caused as many as 130 deaths.

Time for action

The truth is not a lie. According to Airprox’s data, in the last two years of records, 168% of aircraft errors on drones and aircraft. The drone caused chaos around the airport, stopped flying, almost lost the aircraft and caused delays.

In December 2018, a drone report at Gatwick Airport grounded all flights and disrupted thousands of passengers within 24 hours. Fortunately, there is a solution to these problems and return more control to those who work on the ground.

UAV automatic detection and defense solutions can let people know those who pay attention to the sky. UAVs can now be detected up to 20 kilometers away, and early warning can give precious time to prepare and deal with any type of UAV threat.

drone jammer gun high power

The ability to identify the location of the controller gives the airport the opportunity to more effectively liaise with law enforcement agencies to take action against those who violate its airspace. It can identify a specific drone model and the actual serial number of a single drone that has been detected. This is enhanced by the flow of information to be able to pinpoint the heading, speed and altitude of the drone-all potentially key facts that could affect the actions taken by air traffic control.

Portable drone jammer has become a popular anti-drone technology option, suitable for police forces that require drone detection on the move, but when it comes to airports, the fixed version may see the most demand .

6 ways to prevent decoder theft

When the car owner locks the car, it intercepts the decoded signal sent from the car’s key to the car’s central control lock device, analyzes the frequency and data in it, and copies this signal to control the car door lock and easily steal the owner’s car or car property.

The car GPS jammer has a low technical content. The principle is to send out a frequency similar to the original car key signal, and the signal is strong, covering the original car key signal, making the vehicle unable to lock the door, and taking the opportunity to steal the property or the vehicle after the owner goes away .

car gps anti track blocker

“This kind of device is a decoder, rather than a codecutter, because it mainly relies on intercepting the signal to copy the signal.” Master Su said, the public need not be too panic, because only when the owner of the car is opening or locking the car, it is illegal. Only the disciples can take advantage of it. However, in order to avoid property damage, Master Su reminded the majority of car owners to be more careful when parking.

Learn the following 6 tips to reduce the chance of theft of vehicles and their belongings:

1. When you lock the car, pay attention to whether there are suspicious persons within 10 meters.
2. When locking the car, the owner should not be too far away from the car to reduce the range of sensor sensing by the decoder.
3. When using the car anti-theft alarm, install a mechanical anti-theft device and install several concealed locks, such as steering wheel locks and gear locks, so you are not afraid of any decoder.
4. Look for a more side-by-side anti-theft method, do not install the anti-theft device in a fixed position, which increases the time of the thief’s crime, and the thief will lose patience, thereby reducing the chance of successful theft.
5. Load the GPS global positioning system on the car. Even if the car is stolen, the police can quickly locate the stolen vehicle and retrieve the stolen vehicle as soon as possible.
6. It is still necessary to emphasize that you should not put valuables such as leather bags, mobile phones, cash, etc. in the car to avoid losses caused by criminals.

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.

What are the ways to shield GPS signals?

Whether you are locating business assets or monitoring the location of your loved ones, GPS locators have become undeniably reliable. However, users increasingly rely on these things, which makes hackers even more reason to distort the system. Obviously, any potential interference with how these devices work can greatly damage their performance.

GPS monitoring equipment is mainly used for real-time location tracking, used to monitor property and relatives. Over the years, monitoring equipment has been used to complete legal tasks, including rescue tasks, monitoring sex offenders or monitoring parole offenders. In addition, it can also be used to locate and protect convoys. This equipment can help fleet managers protect their vehicles and ensure rapid recovery in the event of their property being stolen, giving the company an opportunity to obtain lower insurance premiums. In fact, these tracking devices have been used to check the whereabouts of spouses in order to understand potential cheating.

For these reasons, people of course need to interfere with GPS to ensure that their devices always work. However, the irony is that GPS monitoring equipment can potentially compromise personal safety, just as it causes safety. If terrorists can obtain important location information of government property, or even if the wife tries to catch her cheating husband, GPS signals can also be useful to disturb things.

GPS signal jamming equipment and other signal jammer

Different methods of confounding or interrupting GPS signals will also depend on the type of surveillance equipment used. The most direct way to avoid being stalked is to destroy the GPS device and ensure that it does not rejuvenate. But if the intention is to tamper with it secretly without knowing the installer, it is easy to obstruct or weaken the transmission of the tracking device by using these instruments:

1.Metal shield

This is a cheaper option. Just encapsulate the tracking device with any metal covering (such as brass net or lead camera film protective film). The thieves allegedly used refrigerated trucks to transport vehicles equipped with GPS tracking devices to avoid being tracked.

2. GPS jammer

GPS jammer is primarily sold online. Inserting it into the 12v adapter in the vehicle can now damage GPS radio signals within a certain range.

3. Mobile phone signal jammer

This device is a mobile phone scrambler, which means it can avoid mobile phone use. If an automatic tracking device is used, this scrambler will prevent the wireless tracking device from sending real-time location updates.

Use jammer properly and do not hurt others’ right

More and more people are increasingly concerned that their privacy is leaked and that their privacy is consciously protected. We all know that there are many ways and tools to tacitly steal our personal information, and even unwittingly.

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 has leaked from these devices too. You can say that your wireless gadget is the double agent of the stolen person.

We use Wi-Fi connection, but we don’t know that it can be hacked easily. We use Bluetooth, we have never heard of Bluetooth hacker technology. If we use GPS to determine where we are and how we get where we need, we will find gps tracking there.

From these aspects, it is not difficult to understand why these cell phone 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 can affect other agencies, like gps jammer can interfere with other GPS navigation. So when we use jammers to protect our privacy, we shouldn’t forget the rights of others. The jammer should be used accordingly.

This is the advice we give you to use the jammers appropriately:

Do not use traffic jams in public places. We recommend that you use blockers in a private place. Don’t try to open it in public places because you can violate the rights of others. You are free to use jammers in your car or at home. Also, choose a signal blocker with the right work area that you need to avoid to bother someone else.

We have the right to defend our privacy, but we should not violate the rights of others. You should remember that other people want to communicate freely. Don’t try to block them. Because there can be an urgent call.

Find the frequency you need to jam and select jammers with the appropriate working range. Here you will find what you want.

Good helper when ordering university classrooms – GSM jammer

The current situation of the university classroom

“Classes should focus on listening and attention,” a phrase even schoolchildren are familiar with, and it seems to be a joke in today’s free, mobile college classrooms. To this end, a university in this city was surprised to find that there were no communication devices in the classroom. But for two days, the school voluntarily withdraws this GSM jammer equipment. This seems to indicate that this step is not effective. How can the classroom environment be cleaned?

Instant messaging, editing documents, downloading files and games … Electronic devices such as cell phones and tablets can be used in a variety of ways. “After a while, I don’t think it’s a little less,” she said. “I think it’s a little less,” and it’s a reflection of the lives of the phubbing people, and a lot of them are still college students who get an education on campus.

Coping strategies of university administrators – cell phone jammers.

A university student said online that her school, the central information institute at Tianjin University of Technology, installed a cell phone jammer in every classroom so that students could listen carefully. For each class there is an isolated island that teaches the corridor building and occasionally visits the teacher there.

To this end, the reporter immediately contacted the school to confirm that students should focus on listening well, as management should do so, and investigation and reasoning is required.

Then reporters also got the school must respond, dealing with the matter cui teachers said schools in installation shielding device, there are still many problems to be studied, “the school is a professional counseling department, researching blockers can lead to problems, so these two days can be used to clean the classroom environment of a school education management attempt, and no conclusion. ”Cui teacher admitted that while most students can understand the school’s original intent, it is still difficult to accept, and that Schools can only temporarily rely on the traditional way of teaching management for teachers.

“In today’s excessive media, the impact of the developed communications network has not only been broadcast on university classrooms such as meetings, the reunification order of various routine social activities carried out by the brush clan clan, and WeChat messages have been broadcast.” A consensus in the classroom that the lesson plan should not be destroyed, and it is clear that students play with mobile phones in class.

Professor Wu admits that it is difficult to ensure that university classroom ordering is a widespread phenomenon and that there are currently no good university management measures in place. Although the school strives for management on a short-term basis, schools should encourage student self-control in terms of long-term development, improve the cultural atmosphere of the campus, and improve teaching quality.

Jammer compatible with small drones

Drones are developing in recent years. Do you know an unmanned aerial vehicle? An unmanned aerial vehicle is an aircraft that is not occupied by a person (unmanned aerial vehicle). It is also commonly called a drone for short. A small unmanned aerial vehicle that is capable of autonomous flight without remote control. What could be used as a tactical aircraft was never put into practical use. As the amount of drones increases each year, they have used technology made into effective drone out-of-range devices to protect the military and others.

We will start to consider having the ability to deal with drones. The drone is remotely controlled by radio waves. The introduction of cell phone jammer has become influential. By using this device to block the radio waves, the airplane will be disabled. The advantage is that it can deal with annoying drones. In order to verify the effectiveness of the drone in stopping flight, we will consider introducing a test in advance. There is a law regarding the prohibition of flying small unmanned aerial vehicles.

indoor phone jammer

It is expected that a plan will be considered to establish a regulation that can take necessary measures to maintain the security of airspace. There are various new products that attack the developed radio waves. Drones pose a threat to the safety of the general public. Drone jammer is compatible with GPS, 2.4G and 5.8G. Allows it to interfere with commercial and special UAV drone signals. The portable jammer antenna is a design switch, which has been efficient and convenient in emergency situations.

Customers have a basic understanding of mobile phone jammers

It’s no exaggeration to say that people are hearing about cell phone jammer and other types of signal blocking equipment for the first time, and in general, they have little understanding of jammers, and thus know nothing. But anyone can decide which type of jammer to buy. And they have reached the goals they want to achieve through the mobile jammers they purchase. We have to study various knowledge here.

portable gold cell phone jammer

We need some useful information for customers to purchase a mobile phone jammer, but it is only a universal explanation of how to use the GPS radio wave blocker and where it is applied. However, product specifications are also important. Through the product specifications, customers can easily understand the working principle of the signal jammer and help distinguish between different types of radio wave blocking devices. It’s generally very difficult to find this type of information, but anyone has to spend a lot of time on the working principle of that mini jammer .

If you see this, I’m sure you’re looking for how the wifi jammer works and what makes other types of products different. For ease of understanding, here is a description of the parameters and working principles of the portable jammer technology.

All major technical parameters and major functions are incomplete descriptions in other regions, but are fully explained here. With the development of modern technology, a new article on the details of super powerful cell phone jammer work will appear here for you to have all the information immediately. With this information, you decide what type of mobile jammer you will buy.

Communication function suppression device. Development background and utilization of mobile phone suppression device

While convenience has improved due to the rapid spread of communication devices such as mobile phones and PHS, ringing tones of communication devices and noise caused by telephone calls have become a social issue in spaces such as theaters and halls where a quiet atmosphere is required. I will. In one hall, concerts by prominent conductors have even been interrupted. For this reason, the current situation is that operators such as theaters are strongly demanding the development of effective countermeasure technology.

desktop mobile phone blocker

To prevent ringing tones and calls from mobile phones, PHS, etc.
For this reason, there is a movement to prevent annoyance due to ringing sounds, etc. by using wireless equipment (mobile phone suppression device) that has the function of suppressing ringing sounds and calls from mobile phones.

What are deterrent devices such as mobile phones and PHS?
Cellular phones and PHS communicate using radio waves.

A communication function suppression device such as a mobile phone is a device that emits radio waves in the same frequency band as that used by a mobile phone or PHS so that the mobile phone cannot be used around the device.

If this mobile phone deterrent device is installed, the mobile phone etc. will be out of range and you will not be able to make or receive calls.

Nowadays, there is a movement to apply this device to prevent wire fraud. In wire fraud, it is also common for criminals to guide victims to ATMs. The criminal gives instructions to the victim through a mobile phone and tricks the cash by operating the ATM remotely. Therefore, there is a high possibility that a call disturbance around the ATM will lead to the prevention of crime.

The jammer gradually entered the sight of the military

Of all the reports on the harmful use of drones and consumer aircraft in the vicinity of accidents, it is not surprising that another new technology has made the headlines: measuring “anti-drones” or “anti “unmanned” aircraft. The drone GPS jammer has successfully passed the DREP test of the French army, which can measure the level of electromagnetic radiation of human users. In fact, as Bloomberg pointed out, it is not a gun, but a drone jack.

The UK will use advanced drone jammer technology at major public and sporting events to detect, track and destroy control of any unauthorized aircraft flying long-distance terrorists carrying airborne weapons. The US government spent $ 17 billion to buy 50,000 jammers, including “Warlock Green”, “Warlock Red”, “Warlock Duke” and “Acorn”. But at the start of the war, there was a cat and mouse game between the GPS jammer and the improvised explosive device, and the jammer was far behind. They are too slow to adapt and can only provide a few meters of protection. Hell, sometimes two sources of interference get blocked and cancel each other out.
