With the rapid development of mobile communication technology and the acceleration of the process of entering the information society, people have to face the increasingly serious Information security risks. Especially, the functions of mobile phones are becoming more and more Powerful, and they have become a new leak channel and new criminal means, posing a threat to the security of confidential information. Therefore Project On Cell Phone Jammer Pdf came into being, and is widely used in the party and government, military, armed police, public security, education, scientific research and other systems. cell phone jammer Nowadays, it is a common method to install test mobile phone jammers in the examination room, which is a kind of equipment that can effectively prevent cheating.
Whether any kind of electromagnetic wave transmitting equipment is harmful to the human body depends on the human body’s specific absorption rate of electromagnetic waves. The highest radio frequency radiation safety standard SAR recognized by the International Commission for Non-Ionizing Radiation Protection is 2.0, and my country’s standard is 1.5. The transmission Power of the current wireless communication station transmission tower is generally 40W~50W, and the specific absorption rate of the human body to electromagnetic waves is below 1.0 when the distance from the transmission tower is 20 to 30 meters. The Project On Cell Phone Jammer Pdf equipment used in the examination room is a micro-Power device, and its transmit Power is generally less than 3W, and it is used in the corridor outside the examination room. In this case, the human body's specific absorption rate of electromagnetic waves is minimal. Therefore, the radio mobile phone jammer used in the examination room does not pose a hazard to human health.
