CAFE by GE for those who are wondering.

We are renovating our house including all new appliances. I have told my partner to make sure we get non smart appliances. This is why.

Yes I can setup a VLAN for it to be on but that’s not the point.

    The microwave region extends from 1,000 to 300,000 MHz (or 30 cm to 1 mm wavelength).

    2.4Ghz, and 5Ghz are microwaves. Your typical microwave oven operates at about 2.45GHz due to resonance frequency of water. 2.4Ghz wifi is literally a typical microwave’s neighbor.

    The difference is sheer amount of power and shielding. Not the type of radiation.

        It may very well be. However, with how matter-of-factly you said it, some people might not think it’s a joke.

      The water resonance thing is a myth, AFAIK. Strong absorption is actually a bad thing for a microwave oven, because then it would only heat the surface. The way they work is effectively bouncing the radiation through a barely-absorbing dielectric thousands of times, to get the effect really even.

      The frequency is probably just an easy one to build magnetrons for.

        The frequency is probably just an easy one to build magnetrons for.

        The real reason is that that range is reserved for consumer devices so that it doesn’t interfere with actual ISM sanctioned communications as enforced by the FCC. We just also decided to put wifi in the same range cause they’re stingy releasing frequencies for public use.

        But research was done on it cause of course it has been.

        https://iopscience.iop.org/article/10.1088/0031-9120/39/1/006

        This article deals with the generation of microwaves in the oven and includes the operation of the magnetrons, waveguides and standing waves in resonant cavities. It then considers the absorption of microwaves by foods, discussing the dielectric relaxation of water, penetration depths of electromagnetic waves in matter and, in considering the possible chemical changes during the microwave heating, multi-photon ionization or dissociation.

        So you’re likely right that it’s not water resonance, but chassis cavity resonance. I can’t say that I’ve read deeply into it. And thinking about it I remember hearing something about some of the high level stuff that I just read in relation to this article. I probably ran into it in passing and just failed to recall it. But to be frank, I’m okay just calling it voodoo wizardry in of itself. But I have to understand wireless communications stuff for my profession, and it’s well known that it’s basically the same range as wifi 2.4ghz/bluetooth/other consumer standards that sit in the same crowded space.
