Our smartphones, as everyday companions, are now everywhere. So we can usually get in touch at any time. Actually. Conversely, when Cell Phone Blocker Power Gsm 16 Jammer Antennas is used, this will look different. But why do you want to do this? For example, in a movie theater, it makes sense to use a cell phone jammer because you should focus on the movie at this time and it can also prevent recording. Such equipment must also be very practical in schools, so that students will not be distracted. Especially in the retail industry, when you actually have the opportunity to use your phone to quickly compare prices, cell phone jammer In a certain range, the mobile phone cannot establish a connection with the base station, so as to achieve the purpose of prohibiting the use of the mobile phone. The mobile phone is manifested as a search network, no signal, no service system and other phenomena.
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 Cell Phone Blocker Power Gsm 16 Jammer Antennas 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.
