Cell phone signal amplifier have radiation or not?


江苏南京快三开奖结果      People think the amplifier have much radiation , actually the cell phone signal amplifier reduces the cell phone radiation itself . But to make it clear that any kind of cell phone amplifiers will have radiation,normally, China mobile or China telecom operators install amplifiers called repeaters, it is to make up for some signal blind, power generally in 5W or more, but Professional installation will install an outdoor antenna away from the place where the body (in fact, the band of mobile phone radiation 5W leaving one meter above the human body did not affect, and to know that our strongest GSM phones transmit power of 2W, but when you call it is close to your head, leaving the phone in your head is less than 10 cm away, received radiation intensity is far greater than one meter outside 5W radiation source !!),you can buy the cell phone signal amplifier power about 0.2 -0.5W from market , because of when the phone signal is poor,in order to communicate with the base station then will strengthen the emission intensity , while the phone it is the nearest radiation source about the people. The average cell phone signal amplifier outdoor antenna radiated power is less than the phone, and away from the body, the radiation power indoor antenna is more small. Electromagnetic radiation emitted by the phone itself can be transmitted to the base station a few kilometers away from the place, but indoor antenna radiation cell phone signal amplifier issued only cover a radius of tens of meters, Who radiation is big? Think all know! The Phone signal amplifier radiation big  one is the outdoor antenna, but the kind of radiation still no big then the phone itself, and the outdoor antenna far away from the human body , far less than the impact on people the phone you holding! After Improved the network of phone call, the phone itself transmit power will be greatly reduced, so the phone signal amplifier reduces the radiation of phone itself.
