> Shannon's law tells us that higher frequencies are capable of more bandwidth than the lower frequencies, which means high-frequency RF could transfer a lot more information than low-frequency RF systems [4].
Almost: Shannon's law sets a limit on the amount of information that can be transmitted through a channel with a given signal-to-noise ratio and a given BANDWIDTH (it's bandwidth * log(s/n) ). Now, it happens to be the case that systems operating at higher frequencies often (nay, usually) do have higher bandwidth for a number of reasons, but Shannon's law doesn't care what carrier frequency your channel uses.
