224GB/s, killer security, no radio interference—but you can't block the beam.
Light is almost certainly the fastest thing around. So it makes sense that "light-based wireless communications," or LiFi, could blow the theoretical doors off existing radio-wave wireless standards, to the tune of a maximum 224GB per second. [Edit, 2:40 p.m.: It does not make sense, and those doors would remain on each rhetorical vehicle. As pointed out by commenters, radio waves, in a vacuum, would reasonably be expected to travel at the same speed as light. Ars, but moreso the author personally, regrets the error.

Lol, they still don't quite understand, but at least they pointed out they made a mistake
