you can bring a jammer in the car

Although the 4G network has been widely covered, I don’t know if you still feel this way. When you use 4G at home, the signal will still be very stuck and slow. Sometimes even 2G jumps to no service, which is just a breakdown.If the signal at home is weak, and the signal outdoors is slightly better, it means that it is caused by the surrounding building environment, and the signal is poor due to environmental factors. This problem can still be solved. A good cell phone jammer is essential. What are the special features of home mobile phone signal jammers? How should we choose? Look down and find out.

The working principle of the mobile phone signal blocker (also known as the cell phone jammer and the cell phone jammer is the scan signal generated by the sawtooth signal generator is inverted by the inverter, and then enters the voltage-controlled oscillator for code division multiple access, GSM It is modulated on the same frequency band as the three downlink frequencies of PHS. The modulated scan signal is amplified by the power amplifier. The power of the power amplifier is controlled by the voltage regulator tube to make the transmission power less than 1W. The amplified scan signal is transmitted in the form of radio waves. In the air.

Because the frequency sweeping signal forms random code interference in the message signal received by the mobile phone, the mobile phone cannot receive the normal data sent by the base station, which prevents the mobile phone from establishing a normal connection with the base station, thereby making the mobile phone separate from the base station communication network.As long as the electromagnetic radiation intensity of qualified products produced by regular manufacturers has been rigorously tested by national authoritative testing and certification agencies, the electromagnetic field intensity measured at all sampling points is lower than the “Electromagnetic Radiation Protection Regulations” stipulated by the State Environmental Protection Administration.

privacy security is equally important

In the exam season each year, all parties begin to prepare for the exam. The invigilator has various tricks to prevent high-tech cheating. Among them, the special shielding device for the exam room is still an anti-jamming device. However, Foshan Shangkino, as a well-known manufacturer of signal jammer, reminds that there are many types of jammers, and the user should clarify his needs before purchasing, so as to avoid poor shielding effects and accidents in the examination room, and pay attention to the method of use. Correctness.

Most of the signal jammer devices are used in prisons, schools and factories. The scope is large and the shielding area is large, but the budget is still very limited. So the question is how to achieve the shielding effect with a limited budget, which means you How can you use less shielding devices and still achieve the desired shielding effect? At this time, many businesses will let you increase your budget or give you cheap shielding devices.The cell phone jammer in many places is subject to man-made damage, such as prisons and student dormitories. If the power of the shielding device you buy is not enough, you can only put it on the surface, but it will often be destroyed if you put it in an invisible.

Nowadays, the Internet fills all corners of our lives, shopping, office, eating, car rides, etc…Almost all cannot do without the Internet, 4G signal is not satisfied, web page information cannot be displayed, watching videos, sending messages, playing games, etc. Frame dropping has also become a daily worry.In some places, the signal shielding will be incomplete due to insufficient power of the shielding device, causing unnecessary losses. So the placement position is especially important. This requires a lot of case experience to know. Many businesses on the market have no such experience.

be careful of privacy leaks

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 sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested as the phenomenon of searching the network, mobile phone no signal, no service system, etc.The cell phone jammer scans from the low end frequency of the forward channel to the high end at a certain speed during operation. The cell phone 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 sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested as the phenomenon of searching the network, mobile phone no signal, no service system, etc. Whether there is any obstruction between the jammer and the wireless communication equipment. The interference signal emitted by the jammer will be attenuated to different degrees after passing through the obstruction, please try to prevent it.Indoor-type shielding device is recommended to be placed at a height of about 180cm-220cm from the ground, and the angle is preferably forward.

Choose different places to use different models and models from the purpose. If they are used in the prison detention center military area, they require 365 days of continuous use. In this way, choose a shield with better heat dissipation and stable performance. The choice of different venues is also different.The weaker the wireless communication signal strength in the use environment, the stronger the theoretical shielding effect of the shield.The farther the shielding environment is from the base station, the stronger the theoretical shielding effect of the shielding device.

people should attach importance to information security

Everyone is familiar with mobile phone signal jammers. They have been seen by anyone who has taken large-scale exams.However, many people sometimes wonder whether it will affect the signal radiation of the base station, so that there is no signal in an area. With the progress of society and the development of high technology, people’s level is getting higher and higher. They are placed at the entrance of the exam classroom. This is not a malicious shielding signal, on the contrary This is a manifestation of maintaining fairness, in order to give people a fair environment for the exam.

Nowadays, many elementary and middle school students, each with a mobile phone, some are addicted to games, some are addicted to novels, etc., which are more dangerous for school exams. Baidu has all the answers. If everyone in the exam plagiarizes with their mobile phone, it will violate the exam.

We must take a rational and scientific approach to the mobile phone signal jammer. The text message sent and received by the mobile phone will also become garbled Therefore, the original message cannot be recognized.Now mobile phones have generally become a living habit of adults and children, and the impact is even more important for elementary and middle school students. Playing mobile phones for a long time is very important.The working principle of the mobile phone signal jammer is to send out a specific signal to awaken or interfere with the signal between the mobile phone and the base station, so that the mobile phone has no signal or cannot find the network service. It may affect eyesight, and even more serious is the waste of schoolwork.

jammers can prevent information from being leaked

In the past few years, various types of mobile phone signal jammers have emerged in an endless stream. We are dazzled and dizzy. In fact, not all products are suitable for us to apply to ourselves. Some products are public, so they are not. When we use a cell phone jammer, you will find that no matter where we are, as long as we can turn on such a jammer, no one can search for our wireless signal. In other words, home The effect of the product is more obvious than that of common public products. In such an environment, we can always shield all signals easily, but if we use a public shield, then the shielding effect may be unstable. So we need to understand the specific use effect.

Mobile phone signal jammers are mainly used in examination rooms, and are not limited to examination rooms. They can also be used in prisons, gas stations, mobile phone bomb prevention, oil depots, liquefied gas stations, detention centers, interrogation rooms, courts, labor reform teams, conference rooms, theaters, churches, Only used in libraries, school dormitories, special security and confidential occasions (confidential offices, negotiation rooms, mobile vehicles, mobile political and business dignitaries guarding the scene).

Mobile phone wireless signal jammers are mainly used for domestic college entrance examinations, domestic postgraduate entrance examinations, adult college entrance examinations, self-study examinations and various colleges and universities examinations, as well as various middle schools, technical schools, vocational high schools, prisons, detention centers, conference rooms, etc. , Adverse effects caused by communication with outside prisoners and collusion with others.However, many people sometimes wonder whether it will affect the signal radiation of the base station, so that there is no signal in an area.

jammers can block many kinds of signals

The development of smart phone wireless networks plays an important role in increasing the speed of development. Mobile phones can solve network problems. Mobile phones play a more important role in people’s lives, mobile communications and mobile Internet. Because of this, it caused many problems. Especially in the home network, children are addicted to the network mainly because of the wifi network. Therefore, many families have gradually begun to install mobile phone wifi jammer to intercept the network to control the children’s online time.

Schools, prisons, libraries, reading rooms and gas stations are typical representatives.With the advent of the summer vacation, primary and secondary schools all over the country have started their holidays, but the tests for parents have come one after another-what should I do if the child is addicted to mobile phone chat, what should I do if the child does not have a good rest and plays mobile games in the middle of the night? How to do? These are the questions I have received the most recently. When encountering such consultations, I generally recommend parents to communicate with their children so that they can learn to self-discipline.

The wireless network facilitates people to access the Internet, but the problems caused by it cannot be ignored. Do not indulge in the virtual world and cause harm to their body and mind. Home Wi-Fi radiation will affect people’s health. Do not use it for a long time, you can turn on the Wi-Fi shield to block Wi-Fi signals.This is not only a problem of accessing the network, but also a problem of network security. In order to maintain a good network environment, many places have installed wifi shields to prevent excessive use of the network. This equipment has been widely used in countries and regions around the world.

can jammers solve the noise problem?

In order to prohibit students from using mobile phones, schools usually use jammers to cheat. For safety and management, prisons can also use powerful jammers to prohibit prisoners, communicate with the outside world and reduce threats to the prison. The interference will transmit a high-power signal at the same frequency as the mobile phone, causing the two signals to collide and cancel. This is the basic working principle of any jammer. Simple devices will only block one set of frequencies. If used correctly, mobile jammers are definitely beneficial. Regardless of the environment, those who continue to talk over the phone may eventually remain silent.

These are some questions we collected a few days ago. First of all, can smartphones be immune to interference from cell phone jammer? This is completely unnecessary. Mobile intelligence does not mean that it can only use the frequency band of the signal. Only in terms of hardware and software, the functions of the machine are more diverse, but the frequency band of the communication network still used is the same as the frequency band of the signal. Many customers report that they want to stop using their phones in certain environments and worry about this risk, because powerful and smart phones will not be able to stop.

High-end equipment can block all frequencies at the same time. Mobile phones are full-duplex devices, which means they use two different frequencies. One listens, the other speaks. Some basic jammers can only block one of these frequencies. Advanced phone jammers will not only interfere with all cell phone signals, but also many other signals. It also has a unique frequency switch, which can be selected according to needs.The answer is yes, unless you use these types of signal spectrums, smart phones will use common signal frequencies and will not cause interference to the phone, but there seems to be no such technology.

are you also worried about noise

GSM mobile cellular signal jammer is a device that prevents mobile phones from receiving signals. The jammer is about the size of a box, slightly larger than current smartphones, and has five antennas. Just as parents can choose and have the right to turn off WiFi at home, they should be able to turn off the phone’s signal when needed. Grasping the phone with your hands and putting it in airplane mode may not work. Rotating Faraday’s cage is an extreme behavior that the hat flower shop crowd should try. However, if necessary, you can choose a home phone jammer.To activate it, the person simply presses the button on the top of the device, and all nearby phones will drop.

In the technological age, mobile phones have been upgraded from generation to generation, their functions are becoming more and more perfect, and more and more intelligent.
