Answer
Hello,

Many thanks for this question.

Unfortunately, because this is a health and safety issue I'm not going to be able to comment personally on the safety or otherwise of these technologies because I don't have the necessary medical knowledge to make a judgement myself.

However, I would like to refer you to the April 2008 statement of the International Commission on Non-Ionizing Radiation Protection (ICNIRP) in which they review all the different wireless technologies and assess the latest state of knowledge and research about the health implications of each.   The statement is available here: http://www.icnirp.de/documents/NewTech.pdf and I hope that you find it useful.

I am sorry that this is not as comprehensive an answer as you were hoping for, but I think that it is the best that I can offer you under the circumstances.

I have changed this to a public answer because, as I indicate in my profile here, I do not answer private questions, so that other users of the site can benefit from answers given.

I hope this helps.   Please remember to rate this answer.
