I had tremendous problems at one house where I couldn’t get a wi-fi signal from the main body of the building into a new extension. After discussion with the home owner I discovered that the insulation of the adjoining walls was held in place by a compartment made of foil-backed plywood. It was very effective at blocking 802.11g signals.

If you are looking to reduce your exposure to EMR, then I’d suggest constructing a wearable foil-backed wooden compartment to shield your core internal organs – a few example designs are available on the web:

I can tell you this for an absolute fact: until very recently, the mobile telcos have HATED Wi-Fi as a technology. The thought of some long-running cloak-and-dagger collaboration is as laughable as the idea that $cientologists are in league with the Institute of Psychiatry.

Telcos such as Orange have launched legal challenges in many cities against the provision of free Wi-Fi on the grounds that such networks are “anti-competitive”. Ubiquitous free wireless access is nothing short of terrifying to telcos because it potentially short-circuits their entire business model.

It’s only in the last couple of years that they’ve bowed to the inevitable and started to incorporate Wi-Fi into their handsets and “multiplay” offerings in a belated attempt to claw back some revenue from the technology.

Most networks still attempt to hobble the use of Wi-Fi on handsets to prevent the use of free VoIP applications… The concept of the WiFi “industry” itself is a pretty nebulous one, but the idea that they’re in cahoots with mobile phone providers in some sort of dark conspiracy makes me splutter coffee all over my keyboard whenever I read it.

Important, yes, but when you ignore the multiple provocation studies and cherry pick from poor methodolgy and anecdote, it rather leads one to agree with Richard Dawkins that “there is such a thing as being so open minded that your brains fall out”

There are also ethical issues here. As Goldacre argues “Symptoms [of electrosensitivity] are real, they are subjective, some people experience them very severely, and this is real distress that deserves our compassion. Alternatively, you could cynically exploit them – and mislead them, and frighten them – to sell your quack products, your newspaper, your TV show, and your freelance articles.” Faced with this choice, the last thing we want is to be ‘even-handed’.
