1. it's a WiFi client, in other words, mostly receiver.
2. even if it were an AP, transmitting at max power for hours, it would give out very limited power (zero, give or take measurement errors).
3. you're starting from assumption "wifi baaaad" without anything to support that claim; if it were a nuclear device, I'd see a cause for concern. [citation-sorely-needed] for this assumption.
- cookiemonster11 12y agoWiFi APs do not have a power output of zero. Think about it for a minute, it makes no sense whatsoever.

- Piskvorrr 12y ago"Zero, give or take measurement errors." As related to the GP's assumption "seems a bit harsh to the cat" - in other words, "why are you microwaving your cat, you monster!!111!", not as related to data transfer. Edited to add the direct quote.
- sp332 12y agoThat wasn't an assumption, that was the question.
- Piskvorrr 12y agoOh, okay, that makes sense; I have misread it as a rhetorical question, then. The answer is "no, your cat won't get its brains cooked, not even after prolonged exposure" - there's not even enough juice in the battery to do that :)
- cookiemonster11 12y ago"Zero, give or take measurement errors." Still does not make any sense. It's completely wrong.
- sp332 12y agoYou know wifi operates in the microwave band, right? Microwave ovens operate in the 2.4 GHz band. Wifi is limited to 1 W total power output, but it's not nothing. Edit: More to the point, it's a good question, even if the answer is "no."
- upofadown 12y agoThere is nothing special about the use of 2.4 GHz for ovens. It is just where the regulations arbitrarily put that particular ISM band. Microwave ovens can work on 900 MHz as well.
- sp332 12y agoSure. And wearing a 900MHz one around your neck probably isn't a good idea either.
- Piskvorrr 12y agoIt is chosen somewhat arbitrarily, but it's not completely random: see e.g. http://www.schoolphysics.co.uk/age16-19/Wave%20properties/Wave%20properties/text/Microwave_ovens/index.html http://www.schoolphysics.co.uk/age16-19/Wave%20properties/Wa...
- Piskvorrr 12y agoIndeed: 1 W is the legal _maximum_ as per FCC rules, part 15. Not even all APs are broadcasting at this power level, this is a WiFi client (meaning that it's only transmitting a few milliseconds out of a second), and this is several orders of magnitude below the power levels used by microwaves. In other words, it is "nothing" for the purpose of cooking your cat's brain. This would be "guilt by association: microwave ovens will cook your brains if inserted, therefore anything else using microwaves will, too, no matter what the power." Edit: I see that you didn't mean the question rhetorically - so yes, while this may be a valid concern in the design phase, the total exposure is infinitesimal, even in prolonged use.
