How Signal Jammer Create a Fair Exam Environment
In light of the COVID-19 pandemic, some exams this year have been affected in terms of scheduling. However, the measures taken to ensure the security of exam venues have not been reduced. During the exams, certain schools will be equipped with Signal Jammer, which may affect the communication quality of mobile phone users in the vicinity. But how exactly do these systems work? To understand this, let’s first delve into the principles of mobile communication.
Mobile Communication and Signal Jamming:
Mobile phones, as communication devices, need to connect to nearby base stations before initiating communication. During this process, all information is transmitted through electromagnetic waves. By configuring a wireless signal jamming system, it is possible to block all mobile phone signals within the exam area. The system emits its own frequency to interfere with the reception of signals from base stations, rendering the phones ineffective and achieving the goal of signal jamming.
Comprehensive Signal Blocking:
The Signal Jammer currently used in exam venues are capable of blocking all frequency bands of the three major mobile network operators (2G/3G/4G/5G), as well as Wi-Fi and Bluetooth signals. Therefore, both mobile phones and specialized wireless devices become non-functional within the exam area. This comprehensive signal blocking ensures a fair environment where all candidates can solely focus on their exams, preventing cheating behaviors.
Signal Jammer play a crucial role in maintaining the integrity and security of exams. By effectively blocking mobile phone signals, these systems create a fair environment where candidates can concentrate on their exams without any external distractions. As technology continues to advance, it is essential to implement such measures to ensure the credibility of examinations and uphold the principles of fairness and integrity.
