There's no solid scientific evidence that Wi-Fi is a health hazard, but that hasn't stopped a parade of people from trying to stop Wi-Fi deployment. In the U.S., teachers have sued schools to derail installs, while angel guidance consultants have launched campaigns against Wi-Fi in their free time.

In Canada, colleges have banned Wi-Fi, equating it to "second hand smoke." In the UK, some say they can feel the impact when they enter a room, while others have started using Wi-Fi blocking paint (at $492 per can) and sleep under silver plated mosquito netting.

The scare-mongering in the UK wasn't helped by a recent BBC report that falsely claimed that Wi-Fi creates three times as much radiation as mobile phone masts. The sensationalist program resulted in some London politicians attempting to ban Wi-Fi use in schools. An official BBC complaints ruling has subsequently found the program was misleading.A great quote from ITWeek columnist Les Hatton: "All I can say in reassurance is that this sort of mathematically dysfunctional scare-mongering drivel really makes me cross." As an aside, check out this entertaining cartoon at Wellington Grey that takes aim at the media's reaction to the great Wi-Fi menace.
