Practical application of Signal Jammer in school
In recent years, signal jammers have
appeared in school classrooms, churches, conference rooms and other places for
many times and become indispensable equipment. Its essence is to interfere with
the wireless signal of the communication equipment, so that the mobile phone
can not access the Internet, can not receive the signal from the base station,
and can not send out signals through the network to achieve the effect of
network disconnection. Nowadays, almost everyone knows shielding equipment, and
basically those who have taken the exam should know it. Generally, it will be
found before and after the classroom and when entering the examination room for
inspection. It is not only simple to shield mobile phone signals, but also to
provide a fair competition environment for candidates. The installation of
Signal Jammer may result in no network signal in an area, but it will not
affect the transmission of base station signal.
Examination is a way to test the level
of knowledge. The examination can reflect the students' learning status and
other abilities, in order to ensure the fairness of the examination results.
The examination room has strong discipline, and is equipped with examiners,
invigilators and other complex processes to supervise the examination, plus a
series of anti cheating equipment such as signal jammers. Fundamentally block
the signal source to prevent cheating.
The use of shielding equipment should
be viewed rationally. The Signal Jammer transmits the interference signal of
the specified frequency band and interferes with the mobile signal received by
the mobile phone, so that the mobile phone can not connect to the network. On
the other hand, the order of the examination room is completely guaranteed.
