Why do microwave ovens operate at 2.45 GHz?

They’d been around commercially since 1947. And generally, they operated at a specific frequency: 2.45 GHz. Despite heavy shielding, microwave ovens’ powerful emissions could sometimes interfere with neighboring frequencies, so it was decided that they should be given a few megahertz of space in both directions .

Is 5G a microwave?

What frequency is 5G? All signals fall on the electromagnetic spectrum – from radio waves, to X-rays, and even visible light. Phone networks use microwaves of a very specific frequency to deliver the internet to your iPhone or Android mobile. This was true of 3G and 4G, and it’s still true with 5G .
