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.
Thank you, that makes sense. So the downside is you need line of sight and no interfering light sources?
