How high is the transmitting power of the dLAN® adapter compared to a mobile phone or cordless home phone?
The SAR (specific absorption rate; unit: W/kg) is a physical variable and a measure of the absorption of electromagnetic fields in biological tissue, which causes it to heat up. It depends greatly on the frequency and, due to resonance effects, on the size of the absorbing body. Because for human beings, the size of the absorbing body is relatively constant, the SAR is especially dependent on the frequency. As you can see from the graphic (http://www.devolo.com/pictures/en/faq43.jpg), the HomePlug technology of dLAN® adapters, compared to mobile phone or WLAN technology, has a frequency range that is up to 100 times lower, resulting in a substantially lower SAR. The HomePlug technology uses household electrical wiring as the transmission medium. This means that only extremely small portions of the signal are radiated. To limit radiation from lines used by telecommunications equipment (including HomePlug), the German telecommunications regulatory agency (RegTP) drafted the norm NB30, wh
