Mobile phone jammer is a device that prevents the transmission or reception of signals by transmitting the same radio waves as mobile phones. It is designed to help people solve various problems related to mobile phones, radio signals and wireless connections. Candidates are accustomed to using some high-tech cheating tools during exams. This is unfair, and it is difficult for the teacher to detect with naked eyes. Therefore, some test centers turn on the cell phone jammer during the exam to prevent the mobile phone signal transmission from the root cause, thereby preventing cheating in the exam.

We have solved the four major methods of cracking the signal jammer

Four ways to crack the school signal shielding! Don’t worry about exams

First declare that our company has completely solved this problem!

Method 1: Number segment cracking method

The school uses an older signal jammer that can only shield the old number segments of PHS, China Mobile, and China Unicom, such as the new Telecom Tianyi 186, China Unicom’s Wo number segment and China Mobile’s TD-SCDMA etc. number segment. of! Simply put, the China Unicom and China Mobile numbers beginning with 13 15 and all PHS numbers can be blocked! The beginning of 18 will not be blocked!

Method 2: Band cracking method

Because the school’s cell phone jammer works to shield the mobile phone by interfering with the mobile phone signal of the designated band, so long as the mobile phone’s receiving transmission frequency can be modified to prevent it from being shielded, the jammer can only shield the mobile phone signal of 900—1800MHZ, and the mobile phone The receiving and transmitting frequency of 850-1900MHZ is much larger than the shielding range of the jammer, so as long as the receiving and transmitting frequency of the mobile phone is adjusted to the maximum in the mobile phone settings, the mobile phone signal can be received normally.

Method 3: wifi cracking method:

This method has high requirements for mobile phones and the environment, but the effect is the best and most concealed. The premise is that the mobile phone must have wifi wireless Internet access function and there must be an available wireless network around (it is almost impossible in our first high). After searching and successfully connecting to an available wireless network with your mobile phone, you can still surf the Internet even if your mobile phone has no signal and no traffic. At this time, if you want to find the answer you can’t find, you can use Baidu. If you want to send the answer, you can use QQ. Row. A method of hyper perversion.

Method 4 Bluetooth cracking method:

It is suitable for students with a distance of no more than 50 meters to pass answers to each other. It is also possible to test two adjacent classrooms by myself. Install bluetooth software like bluetooth hacker on the mobile phone, and then both sides turn on the bluetooth visibility. In the software option, there is an option to force the message to be sent via bluetooth. Enter the answer and force it to be sent, and all bluetooth mobiles that turn on the visible bluetooth will accept To the answer, one person sends the whole class to share. The above method is a method that I came up with after several days of meditation. It is dedicated to all the students in a high school who are distressed by the signal being blocked. I hope that using the above methods can liberate students from the abnormal school and get relaxed and happy!

Interpretation of the principle of car jammer shielding remote control signal

The reporter learned from the car market that when many car owners use their cars, the theft of their valuables often occurs, and many car owners are puzzled. He obviously closed the door of the car, and the car was not damaged. How come the contents of your car were stolen? Could it be that your car was pried open by the master key? The netizen “Wind Chaser” found out the secret of the theft of car items after detailed research and search for a lot of information.

The netizen “Wind Chaser” told reporters that in fact, the biggest motivation for him to find out the reason is that the two bottles of Moutai in the Mercedes-Benz that he bought were somehow lost. Originally, these two bottles of Moutai were intended to be given to their own leaders. I hope to upgrade myself in the coming year. Moreover, these two bottles of Moutai are authentic, so once they are given to the leaders successfully, there is hope for the upgrade. I did not expect to be stolen. Losing the opportunity to give gifts to leaders made the netizen very depressed.

It is precisely based on this background that although the netizen also called the police, he could not provide evidence that he did put Moutai in his car and was stolen by someone else, because the car was intact and the case was not filed. What should I do? The netizen can only crack the secret by himself.

Later, the netizen learned about gps jammer and car decoders on the Internet, and finally solved the puzzle. The source of this secret is that the remote control information of the car was interfered by the car jammer, resulting in the car door being not locked at all, and then after the car owner left, those criminals who used the car jammer would have an opportunity to take advantage of it. So simple. In that case, is there any way to crack the illegal behavior of using car jammers?

Car decoder cracks car chip parameters to improve car safety

Many readers may think that since the car decoder can crack the parameters of the car chip, this is a huge challenge to the safety of the car itself. Why does it improve the safety of the car? For this, the netizen “wind chaser” himself has a deep understanding.

After knowing that gsm jammer can interfere with the car’s signal, for the majority of car owners, if they want to prevent the intrusion of car jammers, the direct method is definitely not feasible, and it is difficult to file a case after the products in the car are stolen. Only the dumb can eat coptis. The theft of car products reported on the Internet is actually a fiction when the police find out. How can our police have such a powerful ability?

handheld gps jammer

Therefore, the complete solution to car jammers is to provide car decoders to crack car chips. Then modify the parameters on the car chip to make the car jammer completely invalid. This method has been proved to be unsuccessful, and now many car repair 4S shops also provide such services. Because car decoders and car jammers are actually like the relationship between computer viruses and security workers, one develops viruses and the other prevents viruses.

After modifying the car chip through the car decoder, the netizen “Wind Chaser” has never lost any items since then. It can be seen that the car decoder can indeed improve the safety of the car. Professor Wang, an expert in the automotive industry, also talked about a point of view, that is, after the car decoder modifies the parameters of the car chip, the car jammer cannot read the data of the car chip, and there is no way to obtain the signal of the chip. It cannot interfere with the remote control function of the car.

This is like adding a protective cover to the car computer chip. The interference signal of the car jammer cannot attack the car chip through this protective cover, thus improving the safety of the car.

How to use high-power test room signal jammer

The test room signal 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. The following Texin Electronics as a manufacturer will share the correct use of the test room signal jammer.

wireless network jammer Buy

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. 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 shielding device, 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 high power 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 the 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 to some electronic equipment, try to keep the distance between 1 and 2 meters above the following common equipment: stereo, wireless microphone, radio, computer, TV, Wi-Fi router, etc.

Schools and prisons use mobile phone signal jammers to be safety-oriented

Schools and prisons should follow these three principles when using cell phone jammers

Radio management

The use of mobile phone signal jammers should not be exchanged at the expense of public mobile communications

Among those who use cell phone jammer, some are to prevent cheating in exams, and some are for quietness of the meeting or confidentiality of meeting information. These are all for good wishes and purposes. But there are also for their own benefit. For example, the owner of a public phone may use a jammer to interfere with the mobile communication base station near his business location, so that people working near the public phone operated by him can use the mobile phone instead of working Public telephone calls increase their economic income. In addition, mobile communication operators may also use shielding devices to harm each other’s interests, so that they can gain advantages in certain local competitions in the same industry. In addition, the mobile phone signal jammer is also easy to add software, becoming a veritable eavesdropping

The above list is the purpose of people using mobile phone signal jammers, but no matter what the purpose is, they should not be exchanged at the expense of public mobile communications. In fact, according to research, it is possible to install mobile phone signal jammers without affecting the normal use of public mobile communications. There are three reasons that cause the mobile phone signal jammer to disturb the mobile communication base station signal:

First, users of mobile phone signal jammers did not take into account the communication needs of outsiders at all, and the target was wrong. The mobile phone communication of a small group of people (such as examinees) should be restricted, but the target was expanded to other ordinary people around.

Second, improper use, because the cell phone signal jammer is installed in an improper position or its transmission power is set too large, it should be controlled within a small range but not properly controlled.

Third, the purchased cell phone signal jammer does not meet the approved standards for radio equipment, the power exceeds the standard, or is a low-quality and substandard product. Finding the reason, in order to overcome its impact on mobile communication signals, it is actually very simple: first, use standard products produced by regular manufacturers, secondly, choose the installation location and direction of action, and thirdly set appropriate transmission power. , It is enough to limit the transmitted signal to a small enclosed area. As long as the above three points are achieved, its impact on nearby mobile communication base stations can be minimized.

Improper application of mobile phone signal jammers in schools and prisons may cause unnecessary harm to the human body

Theoretical analysis shows that when the mobile phone signal jammer is working, if the transmission power is too large due to improper setting, in a small confined space such as meeting rooms and classrooms, electromagnetic waves are superimposed in a small space and pass through the walls that are originally separated from the outside. Multiple reflections from the ceiling and the ground will cause people in the room to be exposed to serious electromagnetic pollution. According to the survey, the college entrance examination and the high school entrance examination are the occasions where mobile phone signal jammers are used the most. In some examination rooms where mobile phone signal jammers are used, some parties (the college entrance examination inspectors, examinees and teachers) are irritable and unable to concentrate. Individual examinees Even headache symptoms appear. Various signs indicate that if the transmission power of the mobile phone signal jammer is turned on too large, it will seriously affect the normal thinking of candidates in the examination room.

As we all know, the characteristics of the free propagation of radio waves in the air, mobile phone signal jammers can block mobile communication base station signals in a certain area and achieve their limited purposes, but also harm human health to varying degrees. Therefore, you must use mobile phone signals with caution. Shield.

The functional management department should strengthen supervision and regulate the safe use of mobile phone signal jammers in schools and prisons

Faced with the increasing use of mobile phone signal jammers from all walks of life in the society, functional departments such as the Radio Management and Security Bureau must increase supervision and regulate the use of mobile phone signal jammers

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.

Telephone signal jammer works in museum

As you know, deterrent devices are available in many places. You will often find this device in places such as classrooms, libraries and cinemas. Recently, the museum has introduced this product. This place is a place to visit for culture and history. I came to this place to gain knowledge. However, there is a phenomenon such as the ringing of the telephone. Some people ignore this act. In such places, you must install a cell phone jammer to maintain good manners.

Principles and morals mature oneself. Language and behavior are important to adapt to the environment. Many people use cell phones even though they ignore their own feelings. Many people are affected by electronic products. It causes gps interference. Helps maintain a great environment. There are students visiting the museum. They are at an important stage in life. Huge history, there is a need to study beautiful art. Use telephone jammers to provide a good environment for students.

Telephone network jammers intentionally block or interfere with wireless communications. It’s a solution for phone signals. Prevents mobile stations from receiving signals from base stations. You can also block the traffic lights in the museum to maintain a good environment. It is often used in places where silence is expected. Most people are focusing on this jamming device. This site has relatively new products on the market. I understand that I am interested in jammers. We use high technology to provide high quality products.

Cell phone jammers are used to combat trade in the Philippines

In the Philippines, as part of the campaign against human trafficking, government immigration officials used mobile jammers at Ninoy Aquino International Airport (NAIA).

Immigration said it plans to install high-performance jammers in all of the country’s international airports.

Immigration chief Ronaldo Ledesma said the jammer was a tool to help curb airport traffic.

Ledesma added that the trafficking group connects cell phones to the intended victims.

An immigration official asked not to call it, he said: “The usual destination for traffickers is the travel visa for foreign Filipino workers, the so-called travelers.”

Immigration officials said how the gangs work “sometimes they are only with a few immigration officers at the airport and display the intended victim or victim of cell phones at a specific queue or counter.

The use of cell phone jammer is one of several measures undertaken by business intelligence and interinstitutional anti-trafficking programs, and it has been reported that there has been an increase in the number of Filipino trafficking cases.

Ledesma emphasized: “These mobile jammers will certainly strengthen our fight against human trafficking.”

He said that the office’s real estate department had been ordered to obtain the necessary licenses from the National

To receive the Telecommunications Commission (NTC) to operate the NAIA handsets again as soon as possible.

The Commission is a government agency under the Ministry of Justice that oversees the implementation of Act No. 9208 or the 2003 Anti-Trafficking Act.

John Tugade, head of the BI real estate department, said the jammers and their servers are still available in NAIA.

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.

Use the cell phone jammer properly at school

Modern mobile phones as a collection of entertainment, advice, communication and even office work have greatly expanded their functions and are popular with young people. Education in mainland China, however, has unwritten “hidden rules”. I learned that students are not allowed to use cell phones at school, and even some schools that have clear rules in school are not allowed to use communication tools such as cell phones. The school’s original intent was not difficult to speculate as the Dongguan Five president, called Ye, said, “The goal is to give students the opportunity to learn better and rest.” But will students who wear and use a cell phone delay and stop learning? Are the students who use and use cell phones really “bad students”?

As a modern means of communication, mobile phones are not limited to communication functions. The development of many young people in society, the development of the outside world and even personal development is achieved via the mobile phone. Many students are used to surfing the Internet on their mobile phones, checking the news, noticing events, acquiring information and knowledge, and their status is becoming increasingly difficult among young people. One can say that mobile phones have become a mobile encyclopedia for students. However, the school did not understand the underlying trend of the phenomenon and tried to kill it. Of course, standing on the floor of the school made the right decision.

“Mobile phones influence students to rest and learn”, the reason is well-meaning, but the exposed is the “exam-oriented education”, which is deeply rooted, even “shielding” has such a compromise to hide and distort passivation Educational thinking. The potential incentive to analyze his “good intentions” is that the overemphasis on students’ academic performance should be “blocked” for all factors that contribute to the high score.

Elementary and secondary schools prohibit students from using cell phones and shield students’ cell phone signals from the extreme form of “Test Education Thinking”. Given the students’ extensive knowledge and advice, the university’s requirement should be to find ways to create the right conditions and conditions. Use “under siege” to ensure the so-called “learning and resting” when “teaching” quality “high scores”, essence “wasted” students.

In the information age, cell phones seem to have become a necessity for life, and today it is not uncommon for students to bring cell phones to school. Although small and medium-sized schools worldwide are not allowed to use mobile phones during school hours, this phenomenon has been repeatedly banned. In the past few days, a high school in the province has had to turn off the lights and turn on the “high-tech” signal jammer for cell phones.

With the development of smartphones, it has become inseparable for us, while adults are “kidnapped” by mobile phones. In the meantime, students and even kindergartens are being stopped by mobile phones. Don’t let the child take the cell phone, worry about the “missing link” security, let the child take the cell phone, also influence school and growth. Should the child have the cell phone taken to school? Cell Phones, “Condoms” Are Just Children?

Mobile phone jammer for short-range interference

Is school cell phone nuisance protection harmful to the human body and phone? Users should rest assured that the signal jammer emits a low electromagnetic signal strength, it has undergone the Department of Health, microwave radiation test and certification, the test data shows that the signal strength is not too harmful to the human body .. At the same time, the anti-radiation device blocks only the forward signal of the telephone, so that the telephone cannot connect to the base station, so that the telephone itself is not damaged. GPS Jammer Is there a difference in distance between using signal jammers both indoors and outdoors? A: Yes. The effective distance of the signal jammer (which does not have to be 1-40 meters, depending on the distance of the environment) generally refers to the indoor distance.
