The cell phone signal was disturbed during the exam

The cell phone signal was disturbed during the exam

  • 2022/07/09

During the final examination, the school will turn on the wireless jammer, which will affect the call quality of mobile phone users around the examination room, such as call failure, failure to connect, call drop, intermittent call, network connection failure and so on. After the examination, everything will return to normal. At the same time, in order to ensure that the signals around the campus are unblocked, operators arrange communication engineers to test the entrance and exit of each examination site and the rest area of the accompanying examination in advance, and expand the software and hardware capacity of nearby base stations to ensure high traffic and high traffic during the examination.

In addition to the signal being shielded during the exam, we try our best to ensure smooth communication. We know that every year, in order to prevent cheating in large-scale examinations, all signals in the examination room will be blocked. A full band radio jammer is installed in the examination room. At the same time, a radio monitor outside the examination room can help to deal with the electromagnetic wave signals of those bands that the radio jammer can't care about, and monitor the radio wave signals of unknown sources in real time. The working principle of wireless jammer is to annihilate the useful electromagnetic signals into a large number of useless signals.

The examination room is equipped with equipment, which is more important for the examinee to have a fair and impartial examination. You should listen carefully in class at ordinary times, and you only want to take shortcuts during the examination. This method is not advisable. You only have to be down-to-earth, step by step. Only in the exam can you give a perfect answer.
