Sorry, but how is this faster than wifi?
Theoretical max for Wi-Fi in the 60GHz spectrum in 7G/s. Theoretical max for Li-Fi is 228G/s. Of course, no one is hitting those maxes now but in general Li-Fi is about 10x faster in the real world, or at least is you have the right prototype equipment.
Physics reason- LiFi uses shorter wavelengths so can switch faster.
so if we get to GammaFi we can be even faster
And penetrate walls much better.
Thank you, that makes sense. So the downside is you need line of sight and no interfering light sources?
Pretty much. I wouldn’t worry too much about interference from other light sources, as they are likely to be basically steady and not modulating.
