(3,249 posts)Bandwidth is used whenever information is transferred. Spectrum is different. You are thinking of the "public airwaves" RF spectrum. There are others.
And, actually, two entities can both use the same spectrum at the same time without causing harmful interference (there is interference, but it can be made statistically insignificant.) The GPS transmissions are built on this principle. All the satellites broadcast on the same frequencies (spectrum) but use a different PRN (pseudo random noise) spreading sequence to mitigate the mutual interference, thus improving the overall system spectrum efficiency.
I spent 43 years as a telecommunications engineer, including working on the GPS spectral design. Believe me, the internet uses bandwidth. Lots of it. And if the govt wants to regulate it, it will find a way.
