At the same time, in the college entrance examination in Fujian Province this year, some examination rooms will be equipped with mobile phone signal jammers for the first time after the second-generation ID card readers and metal detectors to ensure that there is no communication signal in the examination room. At the previous simulated radio cheating site for the college entrance examination, technicians from the joint security team dispatched a mobile radio monitoring vehicle to monitor the examination room and the vicinity of the examination room to find the location of the interference source of the cheaters and monitor whether there were suspicious signals. After discovering the suspected cheating signal, the technicians activate the wireless intelligent monitoring and warning system to block it technically, and at the same time use portable radio monitoring equipment to locate the suspicious signal, and quickly find the cheating criminals.

"Once the surrounding geography is complicated and it is difficult to find the signal source in a short time, this set of radio intelligent monitoring and warning system can adopt various methods such as voice suppression, interference signal suppression, background noise suppression and so on to the cheating signal source, so that candidates in the examination room can listen. The answer is transmitted from outside the examination room to the examination room to ensure the fairness and justice of the examination in a short time.” A technician from the Fujian Provincial Radio Management Agency said when introducing the system's functions. This application of mobile phone signal jammer is very successful.
