Wireless Networks - Harmful Emissions??
Discussion
Short answer - no, there's no evidence of any effects, harmful or otherwise. It's non ionising radiation which all of use are bathed in every day from a large ball of fusion 8 light minutes away. But hey, lets not let that get in the way of media scare stories.
You know mobile phones can blow petrol stations up and power lines give you cancer. Or AIDS. Or something.
TV transmitter max tx power - something in the order of 10Kw. So 5 orders of magnitude more.
3G phone absolute max transmit power is 36dBm - which is 4W, and that's very unusual. Usually they're at something like -30 to 10dBm (so peaking at 10mW) depending on radio conditions.

No. It's about as harmfull as the TV/radio signals we've had for years. Lets face it it's only powerful enough to reach 20 meters or so. Your mobile phone probably has a stonger signal. That can reach miles...
Wireless max tx power, 100mW. TV transmitter max tx power - something in the order of 10Kw. So 5 orders of magnitude more.

Agree that they are not harmful. Having studied occupation health and safety throughout my degree (although not specific relating to wireless networks or non-ionising raditation in general) I have a decent understand of the general consensus regarding published literature.
Many studies have been conducted on this topic, some conflicting but the vast majority state there is no adverse health effect
The same can also be said for mobile phones, despite the media coverage the evidence thus far is inconclusive with as many studies showing no connection as those that showed an association.
Just cause I thought id put my research skills to the test
Royal Society of Canada has an “Expert Panel on Potential Health Risks of Radiofrequency Fields from Wireless Telecommunication Devices,” and their most recent update (2004) notes that “all of the authoritative reviews completed within the last two years have concluded that there is no clear evidence of adverse health effects associated with RF fields” (Royal Society of Canada 2004).

Definatly nothing to worry about, for the reasons already given

I like the scare story from some school teacher who complained of headaches...then continued using his mobile phone, putting out 10X the power of the wireless access points in his classroom...waht a load of tosh ! ...I work in the networking industry, designing these things, if there was any chance of harm to the health then numerous companies from the chip vendors, to the end manufacturers would be sued by now ..

And the rest - Crystal Palace analogue TV transmitters are 1MW, and have been for a long time. I haven't heard of increased ill effects in those living near it. Digital transmitters are a lot less powerful though.

Guy's, thank you for the responses.
I do love the wealth of knowledge of Pistonheads!
Now, if someone could post a request for procurement details of HGV's or Warehouse Efficiency Methods I too could shine
Do you actually use 'kan ban' or whatever the stock efficiency method is or is that just A level business mumbo jumbo? I do love the wealth of knowledge of Pistonheads!

You'll mainly see it in Powerpoint Presentations done by consultants right after they've mentioned JIT (Just in Time), FIFO (First in First Out) LIFO and all other acronyms they like to use.
