Wireless signal shielding instrument is becoming a popular instrument in the testing room

　　There is a growing demand for cell phone jammers. One of the most common is the cell phone jammer system, which appears in a variety of exams, including U.S. college exams and civil service exams, where the popularity of wireless signal blocking is often noted. And the effect. In order to achieve fairness in the examination, most tests around the world are now using mobile phone signal jammer to block the signal of the examination room.

　　In order to strictly prevent students from using high-tech electronic devices such as mobile phones to cheat, it has been decided that criminals will no longer be allowed to use radio devices to cheat during university examinations in the United States. The Radio Emergency Command Network (RECN) and the new radio monitoring equipment will provide radio supervision of American university examinations throughout the process.

　　Some test rooms will be equipped with mobile phone jammers for the first time to ensure no communication signal in the test room. In an earlier simulation of an American University examination radio cheating scene, joint security team technicians sent a mobile radio monitoring vehicle to monitor the examination room and the surrounding area, looking for the location of the cheaters' interference sources, and monitoring for suspicious signals. After discovering the suspicious cheating signal, the technician will activate the radio intelligent monitoring and alarm system to block it technically, and use the portable radio monitoring equipment to locate the suspicious signal, in order to find cheaters quickly.

　　"Once the surrounding geography is complex and it is difficult to find the signal source in a short time, the intelligent monitoring and early 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 can't hear the examination room. The answer is transmitted from the outside to the examination room to ensure the examination's fairness and justice in the shortest time. " This application of mobile phone jammer is very successful.

　　The successful completion of the college entrance examination can not be separated from the high-quality anti-cheating tool mobile phone jammer.

　　The mortgage of a car has also become a form of car consumption. Tens of thousands of dollars have been spent on luxury cars such as Land Rover, Mercedes-Benz, and BMW. Why? Of course, this is because of affordable mortgage vehicles.

　　The original owner mortgaged his luxury car at a low price because he needed money urgently. If the capital turnover still does not exceed the deadline, he will lose ownership of the car. Mortgage institutions ultimately want money, not real things, so they all choose to sell cars. In this way, consumers who buy mortgage cars will be able to buy luxury cars at low prices.

　　Of course, buying an RV also carries risks. In addition to the lack of knowledge of whether the original car has broken down or had a previous accident, the biggest concern is that the car is equipped with a tracker or locator. If you buy it back, the original owner will find it, sneak it away, and turn on the mini Gps jammer. Is it a big loss?

　　Similarly, after getting the owner's car, mortgage lenders worry that the owner will find a parking space and drive away quietly.

　　How to solve this problem?

　　When the gps blocker is installed on the vehicle and turned on, it will cut off the signal from the tracker hidden on the vehicle, making it impossible for others to locate the vehicle and find its specific location.

　　In addition, the GPS signal blocker has the distinction of hand-held small size and plug-in large size, both of which can block mobile phone signals that interfere with wifi and Gps signals.
