100x Faster Than Wi-Fi: Li-Fi, Light-Based Networking Standard Released
July 13th, 2023Via: Tom’s Hardware:
Where Li-Fi shines (pun intended) is not just in its purported speeds as fast as 224 GB/s. Fraunhofer’s Dominic Schulz points out that as it works in an exclusive optical spectrum, this ensures higher reliability and lower latency and jitter. Moreover “Light’s line-of-sight propagation enhances security by preventing wall penetration, reducing jamming and eavesdropping risks, and enabling centimetre-precision indoor navigation,” says Shultz.

What happens to people and pets who sit in the beam?
This is an optical technology, not radio frequency. It’ll be LED lights turning on an off quickly. The flicker is so fast that humans will not be able to notice it. Devices will have to be in line of sight to the tranceiver. A phone in a pocket, for example, wouldn’t work. That would fall back to some other wireless technology like wifi or mobile networks.
