    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.

    Hi,
    I have been around RF spectrum of all sorts all my life.
    Nothing bothered me. I guess you're allergic to m/w oven as well as
    cordless phone and cell phone? I had WRT600N and it is back up stand-by
    box now. By any chance are you trolling? Hope not.

    The same rubbish was posted to sci.electronics.repair and precipitated
    the usual endless discussion on cell phone exposure. T'is trolling

    Maybe trolling, but I have experience RF induced nausea and
    dizziness.

    .......it wasn't from low-power WiFi stuff though, I was in a
    tower building that had a lot of different comm equipment in it.

    I was re-running our coax along the ceiling wireways from the
    bulkhead entry to the other side of the room because the sub-
    contractor didn't do it right (suprise, suprise). Granted, my
    head was 1 foot away from high power (one was 20,000W)
    transmission lines of different frequencies, but the effects
    were completely real. I was only in there 20 minutes before I
    started feeling nausea and dizzy. So bad I had to leave. At
    first, I thought it was something I ate, it went away after I
    left the building, but when I went back, and 20 minutes later, I
    was feeling it again.

    Have you ever been in a tower building with 10s of thousands of
    watts of RF power being TX'd on multiple freq's from 6M to
    microwave and had your head 1 foot from all the transmission
    lines for more than 20 minutes ?

    If not, then STFU MR. Know-It-All.

    Did you follow all the safety rules to limit exposure? Long range RADAR
    tends to use the frequencies which can cause damage at lower levels of
    exposure.
    see TABLE C-I. PERMISSIBLE EXPOSURE LEVELS
    A. RF FIELDS
    <http://www.nato.int/docu/stanag/2345/sta2345e.pdf>

    Service Doctors take it seriously.
    ROLE OF THE PHYSICIAN
    a. A person brought to a physician because of a suspected RFR
    overexposure is invariably frightened and agitated. Reassurance to the
    patient will be helped by knowledge of the amount of overexposure. The
    determination of whether or not an overexposure had occurred requires
    careful analysis by experts trained in RFR measurements and dosimetry.
    Many times there is actually no overexposure at all. If no overexposure
    has occurred, it is only necessary to treat the patient for the anxiety
    reaction.
    b. If an overexposure has occurred, an appropriate history and physical
    examination should be obtained. The patient should be questioned about
    what was felt during the overexposure. Did the patient experience a warm
    sensation in the region of his body exposed to the RFR beam? If this is
    not the case, the likelihood of an adverse effect is very much lower,
    unless the individual has a neural deficit in the region exposed. The
    symptoms occurring before and after the overexposure, in addition to
    those occurring during the overexposure should be recorded.
    c. The physical examination should include an ophthalmologic exam,
    especially for lenticular opacities. If there is any evidence of
    possible damage, the patient should be referred to an ophthalmologist.
    The skin should be examined for areas of erythema and for surface burns
    in the vicinity of metallic objects. A neurologic exam should be
    performed to ascertain any paresthesias or paralysis.
    d. Laboratory tests should be performed in accordance with the
    likelihood and the severity of the overexposure. If there are any
    cardiac symptoms present, an ECG should be performed. If there is
    suspicion that internal organ damage has occurred, appropriate serum
    enzyme levels
    determined and urine analyses should be conducted. If there are
    significant neurologic symptoms, it may be helpful to obtain an EEG
    and/or a MRI examination.
    e. Treatment of conditions arising from RFR overexposure should follow
    the same care and attention given to symptoms of any other suspected injury.

    Ditto. I spent quite a bit of time in an anechoic chamber. After
    about 3 hours, I got rather light headed. However, it wasn't the RF.
    The foam had absorbed some noxious cleaning solvent.

    Whenever I go to a high power TV/FM/commerical mountain top site, I
    get a nasty tooth ache. It's quite consistent and limits the amount
    of time I can spend up there. I've considered having the filling
    replaced with something non-metallic (and which doesn't contain
    mercury).

    On the same mountain tops, I find that my eyes sometimes hurt. It's
    not the altitude or glaucoma as I don't have the same problem on
    mountain tops without transmitters. The eye is the most heat
    sensitive part of the body, and apparently I'm seeing some effects.

    I'm also certain that there are long term effects to RF exposure. When
    I first started in the RF biz, I had a full head of hair, a steady
    hand, a positive attitude, and a substantial bank account. After 40
    years in the RF biz, the hair is almost gone, the hand is shakey, my
    attitude is decidedly negative, and the bank account depleted.
    Obviously, this was all due to RF exposure.

    I presented my evidence, which you just casted aside because you

    I wish it didn't. My tooth really does hurt. According to
    discussions with a local dentist, the amalgam used is not particularly
    conductive and is fairly resistive. More like a dummy load than a
    conductor. So, in an high RF field, it gets warm. The dentist
    suggested that what I'm feeling is a slight thermal expansion of the
    filling, putting pressure on the nerve. We were able to reproduce the
    symptoms by placing a heat probe on the filling.

    >John Navas says it doesn't happen, so I was imagining
    >everything, as were you.


    Well, as a leading authority, he doesn't have to prove his assertions.
    Unfortunately, I don't have the same level of authority and therefore
    must prove what I claim. If he says it doesn't happen, then I must be
    wrong.

    I'm fairly sure that moderate doses of high level RF is harmless. For
    example, I just finished an extended rag chew on 440MHz using a 35
    watt radio with the antenna located about 3 ft from my head. I don't
    feel any different and am quite sure it hasn't affected my... ummm...
    what were we discussing?

    It's the little things that cause problems. Time to start a campaign
    against the dangers of local oscillator (LO) radiation. The typical
    clock oscillator and LO might radiate about 1 mw of RF at various
    frequencies. However, there are literally billions of these devices
    in the US, spraying a dangerous RF "smog" everywhere. 1 milliwatt
    might not seem like much but when multiplied by perhaps 100 billion
    oscillating devices, we have megawatts of RF. Much of this insidious
    LO radiation is concentrated in the populated areas. For example, in
    a crowded football stadium, 50,000 cell phones, each radiating perhaps
    1 mw of RF, will produce the same exposure as a 50 watt high power
    transmitter. The average home might have 100 assorted oscillating
    devices, each with an LO running 24 hours per day. I suggest a
    national campaign be started, warning the general population of the
    dangers of LO radiation, and demanding that the government do
    something about it.

    Seriously, your should never take anything I suggest seriously.

    I lied. It's more like 10 microwatts, not 1 milliwatt if it meets FCC
    part 19 incidental radiator, and about 100 times worse after some
    mechanical case or shield damage.

    Let's do the math and see how badly I screwed up. LO radiation is
    typically about -60dBm at the antenna. If there are multiple leaks,
    it might climb to maybe -50dBm.
    -50 dbm = 0.00001 milliwatts = 10 microwatts = 1*10^-8 watts
    50,000 such cell phones would belch:
    5*10^4 * 1*10^-8 = 5*10-4 watts = 50 milliwatts
    (not 50 watts). If each cell phone radiated 1 mw, then we might have
    a problem. In addition, the LO is not always powered on in a cell
    phone, where the battery save algorithm only turns it on during the
    proper time slot. Exposure would have to be reduced by the duty
    cycle.

    Extra credit for estimating the total LO radiation for the continental
    USA. Figure on about 100-500 billion devices.

    Perhaps we should try calculating how much 2.4GHz energy is delivered
    when we're out in the noon day sun to see if a tin foil hat is
    required. Total energy is about 1000 watts per square meter, mostly
    in the visible light region. Still, there's plenty of power in the
    microwave region.

    I'll do the math when I return from from lunch and a bike bicycle.
