Introduction to the interference principle of 5G examination room signal jammers

With the continuous advancement of communication technology, the widespread application of 5G networks has become a reality. However, within the scope of the examination room, the interference caused by mobile phone signals is still a major problem. In order to ensure the fairness and safety of the examination, the examination room signal jammer came into being. This article aims to explain the operation method and interference principle of the 5G examination room signal jammer.

1.Introduction to 5G examination room signal jammer

The 5G examination room signal jammer is a device specially used to block mobile phone signals. It is able to block all mobile phone signals in the examination room, including 2G, 3G, 4G and 5G. The device effectively prevents candidates from using mobile phones to cheat during the examination, thereby ensuring the fairness and integrity of the examination.

2.How the examination room signal jammer works

The examination room signal jammer interferes with mobile phone signals by emitting electromagnetic waves. When a mobile phone enters the examination room range, the electromagnetic waves emitted by the jammer will disrupt its normal connection with the base station. As a result, the mobile phone cannot establish communication and cannot be used during the examination. The best-selling wifi jammers and GPS jammers in recent years.

3.Introduction to the interference principle of the examination room signal jammer

The interference principle of the examination room signal jammer is based on the characteristics of electromagnetic wave interference. Electromagnetic waves are fluctuations caused by the interaction of electric and magnetic fields. They can propagate in the air and will be reflected, refracted or absorbed when encountering objects. The cell phone jammer in the examination room uses this principle to emit electromagnetic waves of a specific frequency, effectively interfering with mobile phone signals and making it impossible for mobile phones to connect normally with base stations.

The interference principle of the signal jammer in the examination room also involves signal attenuation. Signal attenuation refers to the gradual weakening of the signal during transmission. The electromagnetic waves emitted by the signal jammer in the examination room will interfere with mobile phone signals, aggravate signal attenuation, and ultimately cause the mobile phone to be unable to connect normally with the base station.
