How should schools use phone jammers?
The school uses the phone jammer to
prevent students from cheating in the exam. The installation of the jammer
reduces the burden of the teacher's invigilation and, to a certain extent,
reduces the waste of human resources. In the classroom, some students secretly
use their mobile phones to read novels, make phone calls, send messages and so
on, which can be controlled by phone jammers. Up to now, more and more schools
have chosen to install phone jammers, which means that jammers also play a very
important role in schools.
As a very simple communication
electronic device, mobile phone can easily obtain the desired answers from the
Internet of Things. This small and easy to hide electronic device gives invigilators
a headache. However, it is easy for the jammer to disturb the mobile phone
signal. Once the device is turned on, the mobile phone cannot receive any
signal, and students cannot cheat on the Internet through their mobile phones,
fundamentally solving these problems. According to the distance between the
on-site base stations, measure the on-site signal strength, consider the size
of indoor space, and install phone jammers appropriately. This kind of jammer
transmits interference signals similar to that of the base station, covers the
signals transmitted by the mobile phone, thus destroying the connection between
the mobile phone and the base station. The power of the phone jammer will
probably exceed the normal signal strength, thus achieving the desired
interference effect and ensuring the normal progress of the exam.
