In a few months, the annual college entrance examination and high school entrance examination will be ushered in. Every few days before the arrival of the examination season, people who are near the school examination room will usually receive text message reminders, reminding them of the time during the examination period. Within a few days, due to the installation and use of mobile phone signal jammers in the examination room, mobile phone users within a certain range around the school will affect normal mobile phone communication to varying degrees. Then the question arises: What kind of impact is the impact on mobile communication mentioned here? What is the scope of influence of the mobile phone signal jammer in the examination room?
First of all, what we need to know is: in the classroom of the school's examination room, the mobile phone signal jammer installed will not be turned on during the normal teaching period, so in normal days, the mobile phone users around the school will not feel anything special impact. Only when facing the college entrance examination or high school entrance examination, in order to maintain the fairness of the examination and effectively prevent electronic cheating, will the examination room type mobile phone signal jammer be turned on during the examination.
Ordinary people who live near the school observe their mobile phones during school exams, and they can feel the impact including: the mobile phone signal sometimes disappears, or even directly sees that the signal on the mobile phone disappears completely. When using a mobile phone to make and receive calls, there will be intermittent situations, and in extreme cases, the phone may not be able to be dialed at all. Similarly, due to the influence of mobile phone signal jammers in the examination room, when using mobile phones to surf the Internet or watch videos, there may be freezes and data cannot be refreshed. When using chat software, there may be frequent delays in receiving and sending messages, etc.
The above is the situation that may affect the normal use of mobile phones around the school, so how big is the scope of influence of the mobile phone signal jammer in the examination room? This has to be looked at in two situations: the first situation is under normal circumstances, if only the school has turned on the mobile phone signal jammer in the examination room, due to the large number of mobile phone signal jammers working at the same time, although it is enough for all the examination room Classroom signal shielding requirements, but they will also unintentionally affect the surroundings of the school, and the range of influence generally reaches one or two hundred meters outside the school wall. The second situation is that the local communication operator may respond to the notice of the education authority and temporarily close several mobile phone base stations near the school. In this case, the affected area will be greatly expanded, depending on the number of closed base stations And the range they usually cover, specifically, this range may reach hundreds of meters or even thousands of meters.
