Using Signal Jammer to Create a Good Examination Environment
Due to the rapid development of communication equipment and the
continuous improvement of communication technology, mobile phones can now be a
part of the hands, and communication methods have changed from the use of
landlines, fixed phone booths and rigid locations to communication anytime,
anywhere and diversity. At the same time, this has brought new challenges to
social information security. The use of mobile phones to cheat in examinations,
interfere with public order and plagiarize important information often occur.
In the school, the examination should be fair and just, but every time there
are always some people who take chances in the examination and use some
despicable means, which seriously affects the order of the examination room and
the fairness of the examination. However, using mobile phones to cheat often
depends on signals. Whenever and wherever mobile phones send information, they
always need signals. Signal jammers mainly cut off the flow of signals, making
mobile phones unable to contact the outside world. For a long time, the signal
jammer has been effective in cheating in the examination room.
In the field, it has many advantages, such as small size, not
occupying much area, hardly making noise, not interfering with the examination
environment, and not affecting the state of students' examination. In addition,
the signal jammer mainly interferes with the mobile phone signal, making it
unable to communicate, and there is no need to worry that the use of these
shields will affect the normal operation of other electronic equipment in the
examination room. It is also necessary to reduce the signal hazard and
reasonably use these shielded signal equipment.
