Now I'm an ex-radio amateur and am fairly conversant with the principles of radio wave propagation.
In theory, WiFi signals at 2.4 MHz - a shade higher than the 900 and 1,800 MHz signals used by GSM mobiles and base stations - shouldn't cause any problems with users' brains.
However, I've also reported over the years on a number of individuals who have alleged that GSM radio signals have caused them health problems.
My conclusion is that, whilst GSM radio signals don't cause that many health problems, there are a small number of people who are susceptible to health problems from radio wave transmissions.
Fred Gilbert, the president of Lakehead University in Ontario, is reported to have refused to sign off on a campus-wide WiFi network after reading a study paper by the California Public Utilities Commission.
The paper concluded there was a small risk of cancer and other health issues if people are exposure to electromagnetic fields.
Although other reports - presumably funded by the cellular and WiFi industries (or am I just being cynical -Ed) say there are no health issues with WiFi base stations, Gilbert says that this is not good enough.
He argues, quite correctly, that since health problems may not manifest themselves for 30 or 40 years after exposure, the university's student population are at risk.
Of course, as The Inquirer newswire points out, by the the time the students hit their retirement, their brains will have rotted due to the health effects of booze.
Or something like that....
