The mobile phone signal jammer in the examination room is helpful for some important skill certificate exams, college admissions exams, and mid-term exams. For specific exams, shielding signals prevents electronic devices from connecting to the Internet, so that candidates cannot use mobile phones or PHS. The equipment communicates with the outside world to prevent cheating. So, can a cell phone jammer in an examination room completely block the scope of a classroom? If it is a teaching building, how many test room jammers are needed?
The general standard classroom area in a school is about 75 square meters, and the 818B type jammer developed by our company is an example, and the shielding range is about 20-30 meters. Just looking at the data, in theory, it is enough to equip a classroom with a mobile phone signal jammer in the examination room, but this is only in theory. The specific shielding effect still depends on the shielding signal on site, especially whether there are signal base station towers nearby. If the base station is very close, the shielding effect of the mobile phone signal jammer in the examination room will be greatly reduced. Not only that, walls and windows will also have a certain impact on the test room jammer. Some mobile phone signal jammers in the examination room do not have a certain wall-penetrating effect. The windows are closer to the outside, and the signal will be stronger and the effect will be worse. If it is close to the base station, it is recommended that each classroom be placed on only one side of the podium, so that adjacent classrooms can respond to each other and can be shielded to the greatest extent. If the classrooms upstairs also need to be arranged, they can be staggered to form a honeycomb. This arrangement guarantees a certain effect, and the invigilators ensure that the exam is foolproof and completely eliminate the occurrence of cheating on electronic equipment.
In addition, it should be noted that the power of the mobile phone signal jammer in the examination room is also an important factor affecting the shielding effect. Generally speaking, the higher the power of the test room jammer, the better the shielding effect, but it will also affect the surrounding communication equipment, so choose the appropriate power.
In addition, the installation and use of mobile phone signal jammers in the examination room also need to follow relevant regulations and standards. For example, attention should be paid to the distance from other equipment during installation to avoid mutual interference. In addition, the test room jammer also needs regular inspection and maintenance to ensure its normal operation and shielding effect.
In general, the number of mobile phone jammers that need to be installed in the classroom depends on the specific situation, including factors such as the size of the classroom, the surrounding environment, and signal strength. But generally speaking, it is a more appropriate choice for each classroom to be equipped with a mobile phone signal jammer in the examination room, which can ensure the safety and fairness of the examination room.
