Why do mobile phone signal jammers need to be used in exam rooms?
A signal blocker in the examination room is a device used to prevent candidates from cheating using mobile devices such as mobile phones. It emits radio interference signals so that mobile phones and other mobile devices in the examination room cannot be used normally, thereby ensuring that the examination is conducted fairly and impartially.
This equipment is usually purchased by the school or education department and installed in the examination room before the examination. Its working principle is to block the communication signals of mobile phones and other mobile devices in the examination room by emitting radio interference signals, making them unable to work normally. In addition, some examination rooms will adopt other measures, such as setting up metal detectors, surveillance cameras, etc., to prevent candidates from using high-tech means to cheat.
It should be noted that the use of cell phone signal jammers must comply with relevant laws, regulations and regulations, and must not infringe on students' personal rights and property rights. At the same time, safety issues need to be paid attention to during use to avoid harm to students.
The reasons for using a mobile phone jammer during exams are as follows:
Some students like to use mobile phones to cheat during exams. Installing mobile phone blocking devices can prevent students from cheating through mobile phones. As a very simple electronic device for cheating, the mobile phone can easily obtain the answers you want from the Internet of Things. This small and easy-to-hide electronic device gives the invigilator a headache.
The examination room shielding device emits a signal similar to a base station, covering the signal transmitted by the mobile phone, thereby destroying the connection between the mobile phone and the base station. The power of the examination room mobile phone signal shielding device will most likely exceed the usual signal strength, thus achieving the desired shielding effect.
