The controversy is important because WiFi has become an important feature in hospital campus networks, allowing the transfer of voice and data to doctors at the point of care. This can create a dramatic increase in productivity, which is why some hospital networks are saturated and being upgraded.
Why should WiFi be more dangerous than other services which run on similar frequencies, often at higher power? And if electromagnetic waves are truly dangerous, why aren't the cranks going after cell phone companies, or TV and radio stations?
The more this lie is told, just as with any big lie, the more people believe it. If electromagnetic signals are dangerous we're all doomed. If WiFi is dangerous so are all types of mobile communication.
It is well past time we got to the root of this nonsense and stomped it out, once and for all. Before someone really is hurt.
