A test room needs to install several mobile phone signal jammer

  Every June is the college entrance examination season. Before the college entrance examination, the staff in charge of the college entrance examination room are actively preparing for the various materials needed in the examination room. Here is an artifact of the examination room, called a mobile phone signal jammer. Some people also call it a mobile phone signal blocker. This kind of jamming device can effectively prevent candidates from cheating, and can also effectively purify the wireless signal environment around the examination room, so as to ensure the order of the examination room and maintain a good environment. All communication signals can be effectively isolated.

  Wireless signals are an increasing means of information transmission today, and the speed of development is also very fast. If you want to block these signals, then you need to install a cell phone signal jammer. However, in the face of the problem of installing mobile phone signal jammers, many schools are thinking about how many machines should be equipped in a classroom?

  

  To solve this problem, we must first consider the actual and effective interference effect of the cell phone signal jammer, and the interference effect of the mobile phone signal jammer mainly depends on whether there are base stations around the examination room. Strong, this situation will shorten the interference distance of the mobile phone signal jammer. Under normal circumstances, if there is no base station within 500 meters and it is used in an indoor transparent environment, then a classroom probably needs a mobile phone signal jammer. Such a mobile phone signal jammer can basically satisfy the interference of the entire classroom. If there is an operator's base station within 500 meters of the test room, when the mobile phone signal jammer is used, some frequency bands or a certain operator's mobile phone may not be shielded, or the shielding range cannot meet the shielding requirements of the test room. In this case, it is necessary to use a special equipment spectrum analyzer to search for this strong signal frequency, and then use the interference module of the high-power mobile phone signal jammer to target the signal in this frequency band to strengthen the shielding ability. Of course, during the college entrance examination, under the careful coordination of various departments, the base stations around the examination room may be temporarily closed or the signal strength may be reduced to meet the effect of mobile phone signal interference in the examination room.
