With the popularization of the examination system, our life is inseparable from various examinations, ranging from mock exams to entrance exams, adult exams, professional title exams.Because the wifi jammer is turned on all day, the normal communication of the teachers may also be interrupted, which makes the teachers unhappy.The devices will eventually be installed by Italian authorities throughout Italian schools to prevent students from using their phones to cheat during exams.
Many candidates could not stand the temptation and were repeatedly deceived.When the mobile phone jammer is activated, the signal transmission and reception functions of the mobile phone can be disabled within the specified range, making it impossible to dial out and dial in, so as to achieve the purpose of mandatory prohibition.Mobile phones (NTT Docomo, Softbank, AU By KDDI, eMobile, WILLCOM) are prohibited in this space.The mobile phone shows phenomena such as searching the Internet, no mobile phone signal, and no service system.
At present, a mobile phone jammer has appeared in front of colleges and universities, which can protect and effectively prohibit many aspects such as electronic signal cheating.The working principle of mobile phone signal interference in the examination room The mobile phone signal jammer in the examination room scans from the low-end frequency of the forward channel to the high-end at a certain speed during the working process.
This scanning speed will cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent by the base station, so when the mobile phone tries to establish a connection with the base station, it cannot be established.What is troubling is that the current "high-tech" cheating methods are rampant, and schools are often difficult to deal with, because the principles and methods of these "high-tech" are different.Although it is inevitable that signals will be sent and received by any means or methods in the examination room, the test room signal jammer creates a signal shielding area to prevent the transmission and reception of signals and isolate the signals.
Some schools in Italy also plan to open the devices at inconvenient times.In order to pass the exams, various cheating methods emerge in endlessly, and there are also many kinds of cheating methods.Less new forms of high-tech cheating tools, such as WeChat phones, mini in-ear Bluetooth headsets, and more.Today, more and more schools are using signal jammer in exam rooms to combat new forms of cheating.Many schools have to prepare for the exam every year, such as the setting and layout of the classroom, staffing, and how to stabilize the order of the exam room, which makes it more difficult for the school.
