The influence of magnetic field strength on test signal jammer

I believe many people are unfamiliar with the test signal jammer. This is a kind of equipment that has become popular in major examination rooms in recent years. It can effectively prevent candidates from cheating by using electronic signals. It has been widely used now In the university and middle school exams in major schools. Especially in the upcoming college entrance examination season, major schools have to re-purchase a batch of more professional machines and equipment with stronger shielding effect to ensure the normal order of the examination room and maintain the fairness of the examination. However, what we are going to talk about today is , Regarding the influence of magnetic field strength on the test signal shielding device.

As we all know, the effective range of the test signal jammer is generally about 0 to 50 meters in radius. According to different models of different manufacturers, there will be differences in specifics. However, the strength of the magnetic field will actually affect the effective range of the test signal jammer. Yes, because it relies on the magnetic field to isolate the electronic signal, so in specific use, pay special attention to whether there is a base station within 500 meters of the examination room. If it is 500 meters away, it will generally not cause any impact. If it is within 500 meters, it should be judged according to the specific distance. So the best way is to actually put it into use, and then judge how many units need to be purchased based on the actual results. For those who want a stronger shielding effect and a larger range of machinery and equipment, you can contact Beijing Shenzhou Mingda for the price of signal jammers. This is a professional manufacturer and has many years of experience in research and development of test signal jammers. It has been developed for many years. Deeply recognized and trusted by customers, friends who want to eliminate electronic signal cheating in the examination room are welcome to contact and cooperate.

With the continuous progress of society and the increasingly moderate price of drones, more people will own drones in the future, so the intensity of the management of drones will increase, and it is inevitable that some people will not comply Laws, control drones flying everywhere. Or do not register the UAV to do some illegal things, then after the anti-drone system, these illegal things can be properly resolved, that is, interfere with the normal use of the UAV. Forcing the drone to land, thereby ensuring the safety of national airspace and the safety of social security.

In short, the prospects for the development of the anti-drone market are broad, so investors who want to invest may wish to get familiar with the rules as soon as possible to lay a solid foundation for future gains.

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

Cell phone signal jammer manufacturers teach you which jammer is good for prison

In today’s information age, the development of communication technology is changing with each passing day. As a unique member of the communication family, mobile communication plays an important role in people’s lives and industrial and agricultural production. Today, let’s talk about prison cell phone signal shields. Secondly, while mobile phones bring great convenience to people’s lives, they also have some problems that cannot be ignored. Due to the wide coverage of mobile communication networks, the emergence of networks in some occasions makes the use of mobile phones cause people trouble. , Even security risks, such as:

(1) Become a new leak channel, posing a threat to the security of confidential information;

(2) Become a new source of noise pollution, disrupting normal work order;

(3) Become a new unsafe factor and bring hidden dangers to the safety production of enterprises;

(4) It has become a new criminal method, which has an impact on social stability. Therefore, in some places, we should be able to artificially destroy or restrict this kind of network to avoid the harm caused by the mobile network. Under this premise, the cell phone jammer in the meeting room came into being. The essence of the mobile phone signal jammer is: electromagnetic interference is applied to the wireless network on which mobile phone communication depends, so that the mobile phone cannot access the network, and thus cannot receive information from the mobile network, and cannot send information through the network. But it has no effect on the signal generated by the mobile phone.

cheap signal jammers

In order for the mobile phone signal jammer to effectively interfere with the mobile network, it must be ensured that the signal field strength of the jammer should be much greater than the field strength of the mobile signal BCH in the interference area. Therefore, the same jammer uses different locations and the effective area of ​​interference. The difference is that the local BCH field strength is generally stronger as it is closer to the base station, and the area where the jammer reaches effective interference is smaller. Generally, the interference radius can only reach 0.5-9m; if it is farther from the base station, the BCH field strength is relatively weak. Then the radius of the jammer to achieve effective interference is larger, up to ten to tens of meters. Therefore, the local BCH field strength should be fully considered before using the interference device, and then the location, number and combination of the interference device should be determined according to the size of the interference area.

Obviously, the farther the jammer is from the base station, the weaker the field strength and the larger the interference radius, and vice versa. The jammer will lose its interference ability if it is very close to the base station.

The interference range of the same shielding device used outdoors will be doubled than when used indoors. If the interference range is less than 200m, a shielding device is generally installed, which can be hung on the indoor wall with a distance of 1 to 1.8m on the ground; if it is greater than 200m, generally Two or more units should be installed and placed on the front and back walls; if the interference space is outdoors and greater than 1000m, multiple units should be used, and the honeycomb distribution effect is better.

Since the frequency band used by mobile phones is dedicated, the transmission frequency of the mobile phone signal jammer in the conference room is completely within the working frequency band of mobile phones prescribed by the country, so it has no effect on other electronic equipment such as TVs and radios. At the same time, the mobile phone jammer only interferes with the BCH transmitted by the base station received by the mobile phone, so that the mobile phone cannot establish contact with the base station, so it has no effect on the mobile phone. Furthermore, although the signal field strength it emits is stronger than that of BCH, it is far weaker than the electromagnetic radiation field generated during a mobile phone call. Therefore, it will not cause harm to the human body and can be used for a long time with confidence.

Drone code project – More Linux for aviation

More than 1,200 developers are working on drone code, with some projects recording up to 150 code commits a day. The individual projects include, for example, APM, Mission Planner and DroidPlanner. The platform is used by many companies that are among the great innovators in the field of drone technology. “Open source software and collaborative development are the driving forces behind technology in the hottest and most advanced areas. The drone code project is a perfect example of this, ”said Jim Zemlin, Executive Director of the Linux Foundation. “By becoming a Linux Foundation Collaborative Project, the drone code community can access the resources that such a massive project needs in its breakthrough phase. The result will be even greater innovations and a common platform for drone and robotics open source projects. ”

The development of drones has increased enormously in the last two years due to the lively developer community and the opening up of new areas of application for drones. The latest estimates from Teal Group, an aerospace market research institute, have shown that global spending on research, development, testing and evaluation of drone technology will increase to $ 91 billion over the next ten years. From environmental research to nature and animal protection to emergency services – more and more areas of application are being recognized for drones apart from commercial or military purposes. In addition, the drones’ capabilities for analyzing, storing and displaying data open up completely new fields of application in the business context. Hundreds of thousands of developers and manufacturers around the world are contributing to drone technology and its future. The drone code project will support the innovations of these technologies and drive the integration of better, cheaper and more reliable open source software for unmanned aerial vehicles.

I am very excited to see how the development will continue in the future. The drones offer great potential, but as with any new technology, new questions arise. This is primarily about data protection (e.g. espionage & WiFi sniffing) and privacy (photos and videos). An industry that will specialize in countering drones is likely to develop soon. Certainly also a very interesting research area.

The development of unmanned drones inevitably leads to the rapid development of unmanned drone jammer, because the harm caused by them needs to be avoided.

Communication freedom and jamming devices

Recently, there are many people who use smartphones. Many people have the right to freedom of communication. Freedom of communication is the right of the people to freely use communication means such as letters, telegrams and telephones. However, there are phenomena in which this right is abused. I have a cheat problem using a mobile phone in a recent exam. There are also phenomena such as wire fraud on mobile phones at financial institutions. In many halls, it’s common to see your phone ringing and obstructing viewing. It is necessary to promote public welfare, such as ensuring quietness in a specific space, in order to prevent annoyance due to ringtones from smartphones. Allows installation and operation of cell phone jammer.
