In the always-present effort to speed up informational exchange, scientists have already started investigating Visible Light Communication (VLC), basically a wireless version of fiberoptics, that uses flashes of light to transmit information. Adding VLC to 6G spurred the UMass Amherst team to dig even deeper.
First, some background on 6G. As a refresher, 5G—what
is considered the fifth, and most recent generation of cellular
broadband networks—is still in its infancy. True 5G networks operate in
millimeter-wave frequencies between 30 and 300 Gigahertz, which are 10
to 100 times higher frequency than previous 4G cellular network. (Some
cell phone providers cheat, however, by claiming the upper end of the 4G
spectrum as 5G)...<<<Read More>>>...
