The most common one is the cell phone jammer system that appears in various exams, including the American College Test and civil service exams, where the popularity of wireless signal shielding is often noticed. and effect. In order to achieve fairness in exams, mobile phone signal jammers are now selected to block the signal in the exam room during most exams around the world.

　　In order to strictly prevent candidates from cheating using high-tech electronic devices such as mobile phones, it is decided to no longer tolerate the behavior of criminals using radio equipment to cheat during the American College Test. The radio emergency command network and new radio monitoring equipment will conduct radio supervision on the American College Test throughout the process.

　　Some test rooms will be equipped with cell phone jammers for the first time to ensure that there is no communication signal in the test room. In the previous simulated American College Test radio cheating site, the technicians of the joint security team dispatched a mobile radio monitoring vehicle to monitor the examination room and its surrounding areas, to find the location of the interference source of the cheaters, and to monitor whether there were any suspicious signals. After finding the suspected cheating signal, the technicians will start the radio intelligent monitoring and warning system to technically block it, and at the same time use the portable radio monitoring equipment to locate the signal jammer device, so as to quickly find the cheating criminals.

　　"Once the surrounding geography is complex and it is difficult to find the signal source in a short period of time, the intelligent monitoring and warning system can take various measures such as voice suppression, interference signal suppression, and background noise suppression for cheating signal sources, so that candidates in the examination room cannot hear the examination room. The answer is transmitted from outside to the test room to ensure the fairness and impartiality of the test in the shortest time." This application of cell phone jammer can be described as a very successful.

　　The successful completion of the American College Test work is inseparable from the high-quality anti-cheating tool-cell phone jammer.
