Will wireless communication affect your health?

The electromagnetic radiation is inevitable when any electronic product is in working condition, and the radiation of the wireless network is actually very weak. Cell phones, PHS and other wireless phones have become part of our lives, so we compare GSM and CDMA phones with our wireless card devices.
Mobile phones have proven to have considerable radiation. But the World Health Organization said in a statement that some people have linked some changes in cancer and brain activity to the use of mobile phones for some time, but so far no study has confirmed this assertion. The statement said that the only certainty is that using a mobile phone can increase the user's temperature slightly, but the high-frequency field generated by the mobile phone does not cause cancer.
The GSM mobile phone power standard is 0.6W-2W, and the CDMA power standard is slightly lower. The electromagnetic radiation values ​​of GSM and CDMA mobile phones range from 0.2 to 1.5, and the difference is not large.
Within the limits specified by the ITU and FCC standards, that is to say, the radiation of the two mobile phones to the human body is in line with environmental requirements.
Our wireless communication equipment (wireless transceiver, wireless repeater, etc.) uses 9V 300mA power supply, internal step-down to 3.3V operation, assuming that the wireless device full power working state 300mA current reaches the peak, then the power is 3.3VX 300mA=0.99 W, according to the theoretical calculation formula of electromagnetic radiation intensity: S (power density) = P (transmitting power) / 4Ï€r (distance between the transmitting point and the measuring point), then the theoretical value of electromagnetic radiation in the range of 1 meter from the wireless device Is: 0.99W / 4 x 3.141 x 1M
= 0.777
The value of 0.777 is assumed to be the theoretical value when the current reaches 300mA. In the actual communication state (non-standby), the wireless communication device will not reach this theoretical peak, and the wireless relay and other devices we recommend wall mounting, it is not recommended to install. At a distance of only 1M from the range of human activity, the electromagnetic radiation intensity absorbed by the human body is actually lower.
From the results, if the wireless card device is compared with the mobile phone we use, the wireless card device is relatively low, which proves that the wireless device has a maximum impact on the human body when communicating in full power state, and one third of the radiation of GSM and CDMA mobile phones. The WHO stated that the high-frequency field generated by the mobile phone will not cause cancer. Our wireless card device is even less harmful and environmentally friendly.
