WLAN and Health

The Wi-Fi Alliance takes any concern about the alleged health impact of Wi-Fi technology seriously. Although questions have been raised, a range of scientific research undertaken to date concludes that there is no evidence that low power wireless networks pose health threats to users or to the general public. Wi-Fi technology meets all national and international safety requirements and emits signals that are typically hundreds to thousands of times below the safety limits.
The World Health Organization has reviewed the various bodies of research that have been conducted and has concluded that, due to the research results and the very low exposure levels associated with Wi-Fi, there is no convincing scientific evidence that weak radio frequency signals from these wireless networks cause adverse health effects.

An independent and comprehensive study sponsored by the Wi-Fi Alliance and conducted by the University of Pennsylvania in March 2007 took 356 measurements at 55 Wi-Fi sites in four countries, under conditions involving higher than normal exposures. The study found RF fields from Wi-Fi in typical environments operate far below exposure guidelines. In all cases, the measured Wi-Fi signal levels were very far below international exposure limits (research C95.1-2005 and ICNIRP) and in nearly all cases far below other RF signals in the same environments.
