Radio Spectrum :
VLF
LF:Longwave radio
MF:Medium wave radio
HF:
VHF:FM radio
UHF:TV,GSM,3G,WiFi,Bluetooth
SHF Microwave radio links
EHF
Ordered by decreasing range and increasing bandwith.

At lower end of spectrum , radio waves travel very long distances.Using them to transmit large amoumts data can be slow.

At the other end, huge transmission capacity over a very short range

In the middle of spectrum is the sweet spot.
