During the annual college entrance examination in China, many schools employ Signal Jammers to prevent students from using their mobile phones during the exam. However, this often leads to issues such as dropped calls and slow internet speeds. This article aims to explore why these Signal Jammers are effective in blocking mobile phone signals and how they work.

Subtitle 1: The Need for Signal Jammers during the College Entrance Examination
The college entrance examination, also known as the “gaokao,” is a crucial event in the lives of millions of Chinese students. To ensure fairness and prevent cheating, schools have implemented various measures, including the use of Signal Jammers. These systems are designed to disable mobile phone signals within the examination halls, preventing students from accessing external resources or communicating with others during the exam.
Subtitle 2: The Science behind Signal Jammers
Mobile phones rely on electromagnetic waves to connect to the cellular network. These waves must meet specific requirements to establish a connection with the telecommunication base stations. The functionality of electromagnetic waves is determined by their frequency. Signal Jammers take advantage of this principle to disrupt mobile phone signals.
Subtitle 3: How Signal Jammers Disrupt Mobile Phone Signals
When a Signal Jammer is activated, it emits radiofrequency signals that are identical to those emitted by mobile phones. Since the frequency of these signals matches that of the telecommunication base stations, mobile phones are unable to distinguish between the genuine signals and the signals emitted by the blocking system. As a result, the mobile phones are effectively “blocked” from connecting to the network.

Conclusion:
Signal Jammers play a crucial role in maintaining the integrity of the college entrance examination by preventing students from using their mobile phones during the exam. By emitting radiofrequency signals that mimic those of the telecommunication base stations, these systems effectively disrupt mobile phone signals. This ensures a fair and controlled testing environment, allowing students to focus solely on their exams without any external distractions.
