Discussion Overview

The discussion revolves around concerns regarding the potential health risks associated with WiFi networks, particularly focusing on the frequency of 2.4 GHz used by many routers. Participants explore various opinions and scientific reasoning related to the safety of wireless technology.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant expresses concern about the health implications of using a 2.4 GHz router, questioning whether this frequency, which also affects water molecules, could be dangerous to humans.
  • Another participant counters that WiFi routers emit only a few hundred milliwatts at most, significantly less than the kilowatt output of microwave ovens, suggesting that the risk is minimal.
  • It is noted that Bluetooth devices have varying power outputs, with Class 1 devices being comparable to mobile phones, while others are much lower, indicating a range of emissions from different technologies.
  • Some participants highlight that outdoor exposure to natural radio emissions is vastly greater than that from WiFi, implying that concerns may be overstated.
  • A humorous remark is made about a plan to address unregulated radio emissions from the sky, indicating a light-hearted approach to the topic.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the health risks of WiFi networks. While some argue that the emissions are negligible compared to natural sources, others maintain concerns about the potential dangers of the frequencies used.

Contextual Notes

Participants reference various power outputs and comparisons to other devices, but there are unresolved assumptions regarding the biological effects of different frequencies and the context of exposure.

Who May Find This Useful

This discussion may be of interest to individuals concerned about the health implications of wireless technology, as well as those interested in the technical aspects of radio emissions from various devices.

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.

Maximum power output from a Bluetooth radio is 100 mW, 2.5 mW, and 1 mW for Class 1, Class 2, and Class 3 devices respectively, which puts Class 1 at roughly the same level as mobile phones, and the other two classes much lower.

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!
