In today's life, 4G network and WIFI have become indispensable things in life. All mobile phones and computers must go through this channel if they want to connect to the Internet. It can be said that without 4G and WIFI, mobile phones and computers will be gone. The ability to contact the outside world, but also 4G and WIFI give us too much convenience, some people try to use this convenience to choose to cheat in the examination room, then as a specially developed 4G jammer to counteract these cheating using communication equipment Can it effectively isolate 4G signal and WIFI signal?

The college entrance examination is coming soon. I believe that many candidates are working hard to review and prepare for the college entrance examination, and the school is also actively preparing for the personnel arrangement and equipment preparation of the examination room. Among them, the most concerned is the signal jammer, which is a This kind of equipment is used as a means of counteracting the electronic signal cheating that appears in the examination. It can be a good helper to maintain the stable order in the examination room and protect the interests of the majority of candidates. Nowadays, many people want to use communication equipment to cheat, and major schools are also trying to prevent this phenomenon. Today's signal jammers have become a trend in major schools.

Signal jammers keep exams fair

In life, the college entrance examination is a very important node. It represents an important test for countless candidates to prove themselves. However, in such a sacred college entrance examination, there have been many cheating phenomena in recent years. Candidates who have achieved high scores without working hard will cheat in the examination room by purchasing some communication equipment for cheating. Facing the frequent occurrence of cheating in the examination room, a device called a mobile cell phone jammer has also emerged as the times require. The equipment that effectively eliminates cheating in the examination room has now been vigorously promoted in the examination room as a means of anti-cheating.

Now many schools will install WiFi signal jammers in the examination room to maintain the fairness and justice of the examination room. However, due to the limited signal shielding range of the wifi jammer in the exam rooms, the school is worried that the funds will not be enough. So, is it expensive to install a signal jammer in the exam room? According to the person in charge of the company, the market for WiFi signal jammers in the exam room is still relatively hot in recent years. But just because the market is hot, the quality on the market varies greatly.

You can also prevent employees from using mobile phones at work. In order to improve fraud, many students cheat using smartphones. So the teacher can stop it with a cell phone jammer.

The currently widely used mobile phone standard is our gsm global mobile communication system. GSM standard equipment occupies more than 80% of the current global mobile communication equipment market. It is commonly used, but may be the one most familiar with mobile phone use. Yes, calls and text messages rely on gsm to provide stable network data types. But the GSM network is far more than we know. Powerful mobile signal jammer are one of the criteria that many electronics manufacturers are familiar with and study carefully. The GSM module is used in many areas of life, equipped with common access control security systems and GSM network car security systems and robots. GSM also supports indoor coverage. The outdoor antenna power can be distributed to the indoor antenna distribution system through a power divider. This is a typical configuration method used to meet the high-density call needs of families, and is commonly found in shopping malls and airports. Indoor coverage can also be achieved through wireless signals throughout the building, thereby improving signal quality and reducing interference and echo.

Only cut off the radio waves you want to block. It can run stably for a long time. I am not saying that this will be the electromagnetic coverage of smartphones. I want to know what a radio barrier is.

WiFi jammers and high-power fixed signal jammers used in public places and enterprises. A mobile phone jammer is a device that transmits signals in the frequency range used with mobile phones, and can transmit signals correctly and is subject to strong interference. The simple principle of wifi jammer is to interfere with mobile phones. The second measure is to help people open certain parts of the mobile phone logo. This approach is gradually accepted by more and more governments. They are considering cell phone signal technology, courtesy in public places, and the use of mobile communication devices to legalize the closure. This is the future of cheap cell phone jammers and a promise to quiet public places.

The working principle of mobile phone jammers is similar to that of jammers because the radio frequency they emit is the same as the working frequency of mobile phones. This will cause enough interference and you will not be able to connect the call to your phone. Currently, there are two types of cell phone jammers available. The first type is usually a small device that can block the signal from a cellular tower to a single cell phone. The blocking frequency is 800MHz to 1900MHz. Most devices using this technology can block signals within a 30-foot radius. Mobile phones in this area do not display signals at all. Now you can politely ask them to leave quietly, or you can buy a cell phone jammer to leave them alone.

The situation of malicious applications in the most popular mobile operating systems at the moment proves this fact. As you may know, to install the application on your Android smartphone, you need to approve all permissions required for the application to function properly. In addition, most users have not read them yet, so malware will invade Android and approve everything to install apps faster. At this point, the fact that the app wants to send quality text messages to short phone numbers is missed. However, there is no guarantee that it will work. To ensure the safety of your personal information, we recommend that you avoid public hotspots and use mobile jammers. In this case, this error is not only effective. It is important to remember that your personal information is indeed valuable, and many large companies sell lucratively, so you need to protect it.

Mobile personal communication has brought convenience to people's daily life, and the adverse effects of prisons, detention centers and similar occasions have become more prominent. Once a mobile phone is illegally detained and put into use, it will bring great harm to the management and safety of prisons, detention centers and other places. Therefore, a truly effective mobile phone shielding system should be established to provide strong scientific and technological protection for prisons and detention centers. However, due to the current mixed market, many cheap mobile cell phone jammer are

The radio waves emitted by mobile phone signal interference products are very weak, within the range of weak radio waves stipulated by the Radio Law. Since it is not a radio station in the telecommunications business, there are no legal issues or grayscale issues. Since radio waves are very weak, even such weak radio waves will be interfered. When using a cell phone jammer, even if the smartphone or cell phone is turned on, simply putting it on the porch will block the communication function. It is an interception device used to prevent car positioning. When you turn off the device, you can turn off the radio waves.

Mobile jammers are not only suitable for university entrance exams, but also for qualification exams, high school entrance exams, national exams, etc. This means that cheating using mobile phones has been discovered one after another. I think this method of installing mobile cell phone jammer and temporarily "stopping service" test sites is the most effective measure. A radio station license is required to install the equipment. By transmitting a weak radio wave of the same frequency as the radio wave of the notification message from the mobile base station, communication is blocked and subsequent location registration and polling become impossible, so the display of the mobile terminal becomes "out of service area". Communication Was suppressed. We will also introduce this device around the bank. We will start to restrict the use of mobile phones at ATM corners.
