Introduction to the working principle of the mobile phone signal jammer in the examination room
With the improvement of people's living standards, a large number of smart phones have been put into use, and the use of smart phones to spread information in learning has had a serious impact on the fairness of the test. Therefore, the mobile phone signal jammer in the test room is introduced. The test room signal jammer is to shield the signal in the smart device and prevent the smart device from connecting to the external network, thereby protecting the fairness of the test.
The mobile phone signal jammer in the examination room is a new type of signal shielding device, which is usually based on wireless communication technology, can be connected to the mobile phone signal space jammer, and can also realize functions such as video surveillance and whitelist application authentication. It is divided into static and dynamic shielding.
Static shielding is mainly to block smartphones or wireless devices through a designated area (such as an examination room) to prevent external devices from entering, and achieve the purpose of shielding by setting the radio frequency amplitude; while dynamic shielding is to use changes in radio frequency to realize signal shielding of smart devices , to achieve the effect of signal shielding through radio frequency changes. Whether it is static shielding or dynamic shielding, the fairness of the exam can be achieved. With the mobile phone signal jammer in the examination room, candidates can take the test with confidence, the test room administrator can better manage the test process, and the test results will be more fair and accurate.
The mobile phone signal jammer in the examination room can not only shield smart devices, but also can shield other wireless devices, such as computers, WIFI, GPRS, etc. It can be used not only in examination rooms, but also in various public places, such as stadiums, etc., for shielding cell phone signal to protect public safety.
The mobile phone signal jammer in the examination room is a new technology. Its function is to effectively shield the signal of smart devices to ensure the fairness of the examination and public safety. It is easy to install and low in cost, but its safety has attracted much attention. . Because it may be maliciously cracked and used illegally, when using the mobile phone signal jammer in the examination room in public places, you should pay attention to protection and security. Encryption can be used to ensure the security of signal shielding.
