    More talk about RF exposure, cellphones, now it's wifi.

    The best way to lower your risk of death is to stay out of moving vehicles.

    I have a wireless router that runs 24/7, about 4 ft from my brain. I rarely
    use my laptop at home anymore, so I don't need wifi very often.
    However I have two computers and an Xbox that are hardwired into the
    wireless router. I can't just unplug the wireless router.
    I assume there is a simple router?
    Can I connect two computers and the Xbox to the simple router and then
    for a fourth connection go to the wireless router, then just power up the
    wireless router if I need wifi?
    I don't like hats, especially those uncomfortable tin foil hats.
    Hey, do you think there is a market for felt linings for tin foil hats! :)

    Yeah - sounds like a good idea.
    It's probably safe to keep the configuration you have. Actually, tinfoil
    makes a quite comfortable cap, and who's going to see you anyway? ;-)

    As for a market for felt liners, just get a bolt or so of felt, make some
    hat liners, and see what the traffic will bear. ;-) People will buy almost
    _anything_ off ebay. ;-D

    On most WiFi routers you can turn off the radio. I know that's true of
    Linksys and Netgear products.

    Maybe there is. At least we already have highly sophisticated scientific
    tests of the various styles:

    I'm thinking of moving to a dark part of the universe where the
    radiation density is lower.

    I wonder. It'd still radiate out the connector and the lack of a load
    might cause some SWR problems.
  8. Disconnecting the antenna will cause most of the power entering the
    connector to be reflected back into the transmitter. Some of it is
    dissipated in the transmitter and cable losses and part is reflected
    back towards the connector and so on, so only a small part of the
    original power is actually radiated from the connector.

    Unscrewing the antenna on any larger transmitter may damage the
    transmitter, unless some SWR protection is used, which shutdowns the
    transmitter or at least drops the output power, if there is a severe
    mismatch, thus reducing even further the power radiated from the
    connector into free air.
