The router shown in the figure is Linksys WRT600N Router, that is exactly the one I bought about 4 years ago but currently I operate it at 2.5 Ghz frequency only and I have closed the 5 Ghz band. It is an excellent router no question about it. It was written on the box to keep it 1 meter away from the body. If you are having 5 Ghz band ON for video streaming and even if you are sitting 1 meter away from the device, after 4 hours I think you will feel dizziness and after 8 hours nausea. It happened with me. Never had such feeling before. When I converted 5 Ghz video streaming to wired based, never had such Nausea & Dizziness. 5 Ghz is in microwave range of frequency spectrum. http://www.progneer.com/wp/information_more_public.aspx?search_fd0=72216

I'd want to see results of a double-blind test. Sylvia.

I only have one laptop that uses 802.11a so I can't claim much exposure. To the best of my knowledge, I haven't become ill when using it. > It was written on the box to keep it 1 meter away from the body. That's not going to work because the extra dim LED's are impossible to see unless you shove your face into the front panel. > If you are having 5 Ghz band ON > for video streaming and even if you are sitting 1 meter away from the > device, after 4 hours I think you will feel dizziness and after 8 > hours nausea. If I wasted 8 hours in one sitting watching TV, I'm sure I would experience adverse physical effects. Have you considered climbing out of your overstuffed sofa, and getting some casual exercise, such as crushing the beer cans? I solved two problems simultaneously by installing my bicycle on an exercise stand, and pedaling furiously while watching TV. I had some initial problems with hyperventilation, which did cause some dizziness, but that went away as I adapted to the effort. The only change from standard was to place the TV on the floor, where it was easier to see from the bicycle. There are also physiological causes of nausea and dizziness. <http://www.dizzinessandnausea.com> -- Jeff Liebermann jeffl(a)cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558

There are known side effects.... but they are down in the statistical noise. Although the power levels are similiar, you don't have your head right up against the antenna as in a cell phone. Given the fairly weak correlation between side effects of cell phones (and they are long term effects), and your much greater distance from the antenna, I'd say your risk is very small. The cell phone issue relates to brain cancer and leukemia for very heavy cell phone users, and for specific (older) models. There are a number of peer reviewed papers on this subject. If you are that certain of the effects, have someone turn the offending unit on or off so that YOU DO NOT KNOW WHAT STATE IT IS IN DURING THE TEST. Do a reasonable number of tests (>20) and see if you sense better than 50/50. Your tester should also not know what state the unit is in (double-blind) during your "sensing" period. That requires some form of random on/off switch (10-20 pos rotary sw. with no stops), covering all LEDs, etc. Be aware that the human mind is easily influenced by stimulii that you might think are unrelated to your experiment! For example, if the unit emits the slightest hum, it will probably ruin your experiment, because you would consciously or unconsciously associate it with your symptoms. If you can correlate your experience with the unit being on, then you have something to go on, and it will silence the naysayers. Then it will be an interesting case. Paul G.
