From radio waves to television transmissions to the earth’s own magnetosphere, electromagnetic fields (EMFs) permeate the planet. But not all EMFs are benign or beneficial. For example, directed-energy weapons – which are currently being developed by the U.S. military – demonstrate that EMFs are capable of immense destructive power. And according to numerous online health blogs, some EMFs that we take for granted as being safe may in fact be detrimental to human health.

One such EMF is WiFi – a technology that has become so enmeshed in daily life that it is hard to imagine the world without it. WiFi uses radio waves to enable wireless local area networking of digital devices such as laptops, smartphones and tablets. And since so many of us use WiFi to connect to the internet, the digital economy would struggle without it.
