So, I have been doing some research on Lifi, and here is what's I found. Lifi uses transitional light bulbs, LED's, flourent, etc. Lifi can be shown to be up to 100 times faster than wifi! Tests shown that Lifi can run 50 gigs per second! That's at least 2-3 movies loaded instantly! This is because visible light has a higher frequency than radio, and it uses code to transfer to internet. The thing is, if there is no light, there's is no Lifi, but this Lifi is very efficient and very secure. Stay toned for part 2 and make sure to comment, upvote, and resteem for more content!
