Dont worry if this is confusing.
Lots more on this below.
Wavelengths in and around this band are therefore called millimeter waves (mmWaves).

Wavelength is inversely proportional to frequency (i.e., high frequencies have shorter wavelengths).
This is why really high frequencies can’t travel as far as lower ones.
Speed is another factor.Bandwidthis measured by the difference between the highest and lowest frequency of the signal.
A 5G provider wants to maximize distance, minimize problems, and get as much throughput as possible.
One way to get around the limitations of millimeter waves is to diversify and use lower bands.
They’re used for things like AM radio broadcasting.
Like we mentioned above, there are advantages and disadvantages to using any part of the 5G spectrum.
