Wifi networks. Dangerous for health?

    Wifi networks. Dangerous for health??

    Hi,

    Recently, I have installed a wireless router to create a network at home between 2 computers. This question to say the truth has worried me a bit because searching in the net about this question we can find a lot of opinions warning about the use of that kind of devices as hypothetical danger to the health in spite of not having one definitive conclusion, (maybe by created interests ¿?)

    In my case the router I bought runs to a frequency of 2,4 Ghz. I have placed the router near of me when I work with the computer.

    I have read that to 2,4 Ghz (at this frequency also runs the microwaves, but these ones are isolated in a "Faraday Cage" that avoids the exit of radiation to outside) the H20 warms up when enters -partially- by resonance with the molecule. Does this means that this frequency is dangerous to the human body?

    Are there routers that irradiate to less frequency and therefore they are less dangerous for the health?

    Thanks with anticipation

    Regards

    The wifi puts out a few 100mW at most.
    If you go outside you will receive 1000x as much radio emission from a big unregulated source in the sky.

    The average power output for things like routers is of the order of milliwatts (0.001 W), whereas the output from a microwave oven is of the order of killowatts (1000 W). That's 1000000 times more powerful. I wouldn't worry about it.

    Don't worry- I have a plan in progress even now to shut down that unregulated source!

    The computer company that makes the SPARC processor tried with a copyright suit, the guy delivering the subpoena never came back
