I know pretty much nothing about radio waves, etc etc just that a faster frequency equals to a shorter wavelength, however what I'm wondering what makes certain e.m waves more "valuable" to the companies that transmit them? Is it because it is at a higher frequency? Also, as far as "broadcasting" a signal and being able to receive it does it just all boil down to how "fast" a signal can be switched on/off then transmitted through a antenna that makes it all work?
