Can microwaves affect wifi - and can they harm us?
@Martin Beckett: Kind of, but not really: microwaves are using this band, as it's the most useful (in terms of bang for buck, compared to 915 MHz, 5.8 GHz, and 24 GHz) frequency for heating water dielectrically. And the ISM band was only defined later, as a chunk of space around 2.45 GHz which nobody wanted because of the RF interference from microwaves. Thus, when wireless systems like WiFi were considered, the spec makers were all "Yay, a free band! We'll cope with the microwave ovens somehow". No irony at all - just economics: e.g. 10GHz licenses can be had, but drive up the cost.
