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.

The mobile cell phone jammer is only effective for mobile phone communication, does not interfere with other harmless electronic equipment, and can be widely used. All kinds of conference rooms, auditoriums, courts, libraries, doctors' offices, schools, theaters, hospitals; and gas stations, gas stations, oil fields, oil depots, government, military, financial, securities, prisons, public security command centers, or prohibited in any Place to use cell phone. The characteristics of the radio wave jammer The mobile phone signal jamming adopts the latest SMD components and integrated circuits, with advanced performance, convenient installation and durability. The manufacturing process is strict, stable and reliable. In accordance with the quality system, information security is strengthened to ensure safe production, protect the environment, and ideal and reliable safety products.

The most widely used mobile phone standard today is our gsm global system for mobile communications. GSM standard equipment occupies more than 80% of the current global mobile mobile communication equipment market. It's commonly used, but probably the one most familiar with cell phone use. Yes, calls and texts rely on gsm to provide stable network data types. But the gsm network is much more than we know. A powerful mobile gsm signal jammer is one of those guidelines that many electronics manufacturers are familiar with and study carefully. gsm modules are 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 Outdoor antenna power can be distributed to the indoor antenna distribution system through a power divider. This is a typical configuration used to meet the high-density calling needs of households, commonly found in shopping malls and airports. Indoor coverage can also be achieved with wireless signals throughout the building, improving signal quality and reducing interference and echo.

There are many types of signal jammers, we have to choose carefully

Buying a GSM scrambler, in addition to the gsm network, also needs to shield the signal type, such as whether to shield the 3G and 4G network bandwidth. This way, you can buy a cell phone blocker that blocks all cell phone signals. Also, I bought an electronic jamming device, so I need to think about where to use it. Portable gsm jammer are convenient for indoor and outdoor use, and desktop gsm jammers feature a multi-antenna design. As the name suggests, it will be widely used not only by individuals, but also by prisons, courts and other large venues. Wide range of interference, many types of signal shielding. Personally, I recommend the 8 Antenna Portable GSM Scrambler. It's good enough for your needs and provides a quiet reading environment when you need it. For businesses and critical organizations, a powerful multi-antenna desktop jammer will be your better choice. This is quite evident in terms of functionality and interference radius and is considered sufficient for large-scale applications.

As a result, children's habitual participation in the Internet can lead to many problems, especially in home networks. This is mainly due to the Wi-Fi network. Therefore, many families are gradually installing radio interference shielding devices on their mobile phones to control their children's Internet time. The Internet provides convenience for people to access the Internet, but the problems brought by the Internet cannot be ignored. wifi jammer sales have network security issues as well as network access issues. In order to maintain a good network environment, many places have begun to install such desktop wifi jammers. Used in some places to protect network security and prevent network overuse. Countermeasures are widely used in various countries and regions around the world, and can be reflected in schools, prisons, libraries, reading rooms and gas stations.
