5 Ghz Routers Cause Nausea & Dizziness - To You Too?


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.

Actually microwaves work at 2.45Ghz , which is closer to where you
currently are operating.

Microwave range of frequency spectrum, not operating frequency of a
microwave oven.
World of difference!

Looking at the RF spectrum bands could prove very illuminating methinks.

I get headaches beginning at radio frequencies but it must be tied to its
power output. I can't use a cellphone for long, nor can I tolerate the new
wireless home phones, so I prefer to text. I can tolerate bluetooth
headsets longer, but not as long as a wired phone.

That said, I've not had trouble with AP.

I have heard one definition of microwave frequencies to be 3 to 300 GHz.
However, I have heard a lot in the years around 1980 of transistors being
referred to as "microwave ones" merely due to how well they work in the
GHz range below 3 GHz. That makes me think that the 1 to 3 GHZ range is
"sometimes considered microwave".

As for what the radio spectrum is:

IIRC, USA's FCC regulates radio transmissions down to or even a little
below 20 KHz. I somewhat recall actual practice of radio transmissions at
60 KHz - or was that 50?

And I do somewhat recall FCC regulating radio transmissions at
frequencies as high as a roughly 5 millimeter oxygen absorption band
around 60 GHz, used by satellites for determination of the temperature of
a few various levels of Earth's atmosphere including at least 80, maybe
85% of the mass of Earth's atmosphere.

For that matter, the 30 to 300 GHz band is considered "millimeter
waves" - as in higher frequency microwaves. I have heard of some
oscillator achieving 450 ow was that 470 GHz, with wavelength around
..64-.66 mm.

By some official standard, 1 mm wavelength and associated frequency of
300 GHz is "some official border" between radio frequencies (including
microwave) and "low temperature thermal infrared".
