Safety of Wi-Fi signals

Wi-Fi (or wireless networking) is a way to connect a computer or other device to a network. It uses low-power radio signals instead of cables. The New Zealand Ministry of Health website refers to research on the safety of Wi-Fi signals, concluding that Wi-Fi signals won’t harm your health. Measurements in New Zealand and overseas show that exposures are tiny fractions of the public exposure limit (set out in the radiofrequency field exposure standard). The highest exposures found in two New Zealand schools were 4000 times below the limit, and generally exposures were more than 10,000 times below the limit. Further information can be found on the MoH website.
