Why is the wireless signal jammer device used in the examination room a built-in antenna?
Over the years, as long as there are large-scale exams, it is not surprising to install wireless signal jammers in order to completely eliminate cheating on the exam site. However, many people have only heard of such a thing, knowing that it is a shielding device used to shield signals, and have not carefully observed its appearance. So, what does the wireless wifi jammers look like? A wireless signal jammer is first of all the difference in the appearance of the shell. There are currently two types on the market. One uses an external antenna and the other uses an internal antenna. There is still a little difference in the internal structure of these two types of wireless signal jammers.
The wireless signal jammer with built-in antenna usually installs the antenna inside, which is composed of various electronic components. The shielding device with a built-in antenna like this is mainly for a more beautiful appearance. The shielding device for the external antenna has several interfaces on the shell for installing the external antenna. These interfaces represent signal shields for different channels. Generally speaking, the number of external antennas also determines the advantages and disadvantages of the wireless signal jammer. More antenna shields will also have a wider range. There are also various electronic components inside. Through these electronic components, the purpose of interfering with mobile phone signals can be achieved. The reason why the wireless signal jammer is set as a built-in antenna is because I am worried that some naughty classmates will damage the antenna, which will cause the shielding device to have no effect.
In military activities, wireless jammers provide a lot of help
In the past, wireless jammers may have had fewer applications in everyday life, but in today's technological age, it has become an indispensable device, especially in military activities. This portable wireless jammer can be used in major military outdoor activities.
With the continuous advancement of science and technology, modern communication technology is very convenient. Our communication devices have continued to advance, with great improvements in functionality and performance. Communication equipment is widely used in modern military operations. These advanced devices are of great significance to military activities. Information can be easily conveyed to designated persons.
Will the communication of our communication products be interfered? The answer is yes, we should know that high-tech products produced by technological progress will always be resisted. Everyone knows the importance of information transmission, and the timeliness of information will affect the entire military activity. Therefore, the destruction of the enemy's communication is very important.
In modern military activities, not only wireless jammers can be used to interrupt the communication of the other party, but also various jammers can be used to deal with the enemy's drones or unmanned reconnaissance aircraft. Jamming tools are playing an increasingly important role in military activities role. With the development of science and technology, wireless jammers will be more and more widely used in the military, and will provide important assistance to military activities.
