Networking & wireless: Wi-fi. Are there any health risks?
Just FYI
by drewu - 2/24/06 12:35 PM In reply to: Microwave ovens by unigamer69100mW (20dBm) isn't the legal limit. The limit is actually based on your EIRP, which is the transmitter and antenna combination. 4W (36dBm) is the limit for non-point-to-point communication. An example of 200mW (23dBm) card attached to a 15dBi omni antenna after losing a couple dB in cabling and connectors sits you right at the limit. 23 - 2 + 15 = 36.
need to know about how far wifi can go
by pereranver - 2/25/06 10:34 AM In reply to: Just FYI by drewuI am trying to build a wifi file sharing network at a range of about 4 miles. I need to know if and how i can do this in a cos effective way and if an omni antenna and booster will work?

Listen to reason......
by ROB_213 - 2/23/06 7:02 AM In reply to: Wi-fi. Are there any health risks? by yannisThere are several posts that say there is no hazard, and they are correct!
People who become worried about non-hazardous things because of articles in magazines, etc, can fall victim to those who would sell absurdly worthless gizmos at high prices to ward off, prevent, or otherwise negate the mythological hazard.
Enjoy the benefits of your wireless connectivity and forget the health hazard scare nonsense!
(NT) Yup, just like virus creator and Anti virus creator..

by unigamer69 - 2/23/06 11:26 AM In reply to: Wi-fi. Are there any health risks? by yannisWant to try something interesting?
I have a Linksys WRT54G, with third-party firmware that lets me boost the power output somewhat. I also have high-gain antennae hooked to it.
A foot away is a dual-cassete deck with a turntable (yes, it's old. I use it to dub my folks' old stuff to CD for them). It's hooked up to the sound card of the computer underneath it (the deck and router are on a hutch).
If I switch the deck to tape mode and listen... you can hear little pings and pulses, several every second in bursts. At first, I thought this was being introduced through cables, but then I realized that it only happens in tape mode, and not phono mode.
Also, if I disable the router's radio, it stops.
Conclusion: That noise - presumably the beacon signal from the router - is being picked up magnetically, rather than electrically. By the tape deck heads.
very helpful info on offending neighbour
by duglus - 3/6/06 7:51 AM In reply to: Interesting experiment by unigamer69I eventually figured it out before reading this, but this "experiment" confirms my hypothesis with the offending 'router' (that I do not have, to test with).
The range on these units is roughly 30 meters so it has to be a neighbour on either side. Since the problem persisted when the landlord neighbour to the west had no tenants in their house, it only could have come from The East house.
I have a wireless 2.4Ghz audio stereo transceiver.
The noise problem went from small initially to very large shortly after. Thus showing a disposition of purposeful annoyance; by using the noise generated on my stereo (outside) to find the best results, from the position of their router, upon my equipment.
The machine gun sound became louder than the source music. I liked to play classical in my backyard garden!
What to worry about
by La reina - 2/23/06 12:37 PM In reply to: Wi-fi. Are there any health risks? by yannisYou'd be much better off worrying about heart disease -- it's the number one cause of death in the US and most of Europe. They order: cardiovascular disease, cancer, Alzheimer's Disease and accident (in that order). Alzheimer's victims usually die of pneumonia, a lung condition or a cerebrovascular condition -- so Alzheimer's victims are often declared to die of other causes. Watch out for motorcycles and cars -- very dangerous!
Link to an article
by yannis - 2/27/06 7:40 AM In reply to: Wi-fi. Are there any health risks? by yannisI find the following article,(www.theregister.co.uk/2006/02/22/canada_uni_wifi_ban/). So this is a valid concern. I just hope that people are overreacting and that there isn't a lot to worry about, as most of those who answered my question said.
High Quality Mains Extension
by Mick Thompson - 6/15/08 12:25 PM In reply to: Wi-fi. Are there any health risks? by yannisI've found that plugging my cordless phone and wireless router into a hifi grade mains extension helps to reduce the negativity of the radiation.
Ha what a joke...
by volatileacid - 11/18/09 7:42 AM In reply to: High Quality Mains Extension by Mick ThompsonDon't listen to this one - he's just advertising through scare tactics.
High quality mains extension. Where do they come from :/
Not only high quality ...

hifi = high fidelity. Sounds as the original (from the LP era).
