Just occurred to me that the humble microwave should be a fairly effective Faraday cage, certainly for the microwave spectrum, anyone know how good it is for the relevant communication frequencies?

Considering there's a thing emitting at 800-1000W in there I would say they are pretty effective faraday cages.

I've never had any interferences.

I played online games with some people who mentioned their wifi signal drops whenever someone operates the microwave in the kitchen. (Also, other people had problems when certain old neon lights next to their room were on.)

I've never had that problem, a few minutes ago I tried to make a call and put the phone in the microwave, the moment I closed the door it cut the call.

I'd be worried if I had a leaky microwave.

I've never had any interferences.

All my microwaves in the last 20 years cause interference from several rooms away! Like Bluetooth headsets dropping signal.

I have a device that measures radiation and EMF, and that thing spikes when the microwave is on, too. 😮
