Is Wi-Fi dangerous?

The short answer is no or not really. Although research in health effects with electromagnetic radiation used in wireless telecommunication is still ongoing, so far research has not found a link or proven that Wi-Fi or mobile phone EMR is carcinogenic or harmful. Its microwave frequencies/wavelengths are simply far too inadequate to damage DNA by itself. Perhaps most of all, the signal strengths used in Wi-Fi and cellular telephony is much to weak to cause heat damage or other harms that's been demonstrated with high-power microwaves. Even where there is tentative (weak) correlations between heavy mobile phone usage and brain tumours, no link or cause has been discovered or proven - and such findings may be biased.

Wi-Fi signals only need to be strong enough to be "heard" easily for a few dozen metres/yards, rarely more, while receivers still have to boost the tiny signal (as an induced electrical current) with their own power in order to make it readable to its microprocessors. This means the overall energy can be well below safety regulations. It does not and should not be so strong to cause aggressive heating, arching (sparks between metal items) or such, as a microwave oven or weapon would. Wi-Fi usually uses much weaker signals than cellular telephony at full transmission; while it also often uses shorter wavelengths (higher frequencies), these are also non-ionising and are more easily blocked by objects and air.
