I'm really confused with the definiton. I thought RF is below Microwave frequencies. Is my understanding an old definition that was used when signals to transfer information only had frequencies below microwave? Is there a common state of the art definition at all? Or is it at least agreed in the test and measurement field to include microwave frequencies when refering to RF?

I have been educated beyond my imagination.
