There Are More cell phone jammer In The Examination Room
The most important place for cell phone jammer is the school examination room, especially the important examination occasions such as the high school entrance examination, college entrance examination, graduate entrance examination, and college English test band 4-6. There are also many schools that install cell phone jammer in classrooms for a long time, and they also use them during mid-term final exams during normal times. Some schools even turn on jammers during class.
So, how to install a mobile phone signal jammer in the school examination room to have the best effect? We will elaborate separately for the above different situations. The first situation: For major but temporary occasions such as the college entrance examination, postgraduate exam, and CET-4 and CET-6 English exams, since it only takes a few days, for convenience and flexibility, there is no need to install a mobile phone signal jammer. Just bring the jammer to the test room and plug in before the test starts.
In this case, the placement of the jammer is mostly near the blackboard podium in front of the classroom, and it can be placed directly on the podium under the blackboard-there are usually power jacks here for easy access to electricity. For example, there are many universities in Xi’an, such as Shaanxi Normal University, Northwest University, Shaanxi University of Science and Technology, Xi’an Jiaotong University, Eurasian College, etc., they buy or rent mobile phone signals from Xi’an Kaining Electronics for the fourth and sixth level and graduate exams. After the jammer, place it directly on the examination room podium.
For better shielding effect, you can also put the cell phone jammer on a chair or table, the best distance of 1.5-2 meters from the ground. Of course, it can also be placed directly on the ground, depending on the strength of the local wireless signal, or one at the front and back of the classroom to better guarantee the shielding effect.
If you only want to place a cell phone jammer, and worry that it is difficult to shield the area behind the classroom at the front podium, you can place the jammer in the middle of the classroom side. At this time, the shielding device needs less length on both sides of the shield, and the effect will be better. Of course, the power cord problem needs to be resolved, and there may be no power jack in the middle.
The second situation: long-term use of cell phone jammer in the classroom. At this time, the jammer needs to be fixed in the classroom. There are two things to note here. The first is to be placed higher, 2.5 meters-3 meters or even higher. On the one hand, it is the pursuit of better shielding effect. On the other hand, it is to avoid being damaged by some naughty students, so it needs to be high enough. It is better to place it in the middle of the classroom.
The other is to unify the switch. The cell phone jammer lines in each classroom are all connected together, and the school is under unified control when using and turning off. It can be turned on and turned off with one key, which avoids the trouble of turning on each classroom. Therefore, this use method requires special construction and wiring, which is much more complicated than the first temporary use. Which method did your school use?
