Light-based “LiFi” promises amazing wireless speeds—just not through walls

224 GB/s, killer security, no radio interference—but you can't block the beam.

Light-based “LiFi” is stunningly fast, notably fragile—and now standardized

224GB/s, killer security, no radio interference—but you can't block the beam.

@arstechnica The new gamer cry of “Get out of my light!” is about to be born. :)

@arstechnica Latency could possible be reduced by reduction of channel contention protocols and also by highly directional receivers so that different sources could be distinguished?

BTW, The automotive industry's notions of Vehicle-to-<stuff> methods ought to consider using modulated LEDs in addition to RF based signalling.

@arstechnica can you cross the streams?

@arstechnica I can't find anything about what actual light frequencies this operates in. Is it literally visible light? IR? Microwaves being called "light" for marketing reasons?

@Pxtl @arstechnica “Operating in the optical spectrum..” If I read it correctly.
Show threadPxtlJul 14, 2023
@YurkshireLad @arstechnica that is really vague, since "optical spectrum" often includes everything from high ultraviolet to the deepest infra-red that's on the edge of millimetre-wave.

@arstechnica high speed clacks. Pratchett would be pleased.
