What is Li-Fi? 💡The Next Big Thing for the Internet

Connecting to the internet can be as simple as turning on a light. This new technology could revolutionize Wi-Fi. #newtech #lifi #tech

It's just fiber optics without the fiber.

Ain't no scrolling through tiktok at night with this one

Light is just another form of electromagnetic waves, like WiFi itself. It makes sense to create such tech.

What if I want to sleep in a dark room & stay connected to LiFi 💭

[exosmusic]

All WiFi works on this principle. Light is just an electromagnetic wave.

[LeonSKennedy]

what if you cover the light stream with an umbrella? ☂️ 😮

[YDGFX]

😭 Imagine saying "who the F turned off the lights? turn them back on!". 🤚🏾

[SensoredRooster]

Please explain how this is more secure?

[irfanwar]

This is nothing new, it was tested 10 years ago. Had lot of issues

[jeffreydurham]

This has been the next big thing for a while. I would say they have been working on this for at least ten years already.

Trisha, traditional WiFi also can’t be seen by the naked eye.

[sasgarbage]

Is it available. 😅. I have been hearing it for years

[kenmack]

How on earth would it be “more secure”?

[_of_]

Wow I remember CNET did an article on Li-Fi back in hmm over 9 years ago. Yeah now we have WiFi 7 and Li-Fi was tested vs slow wifi A/B/N

Damn so I can just point my device to the sun and I got internet, now I can watch YouTube from Mars

[ThePIGuy-rihp]

Literally just a 60watt bulb connected to a eathernet to optic convertor box and the receiver is connected to the device😂

Ok, so we're just coming up with... more? Cybersecurity horrors? I guess this is legitimately safer than wi-fi, but I feel like this is *way* too easily disturbed by environmental conditions. It's just too hard to get this to transmit at a bitrate that one can correct for environmental fluctuations, dust on the sensor, etc. I don't really see how this actually would create benefits deployed large scale that wi-fi doesn't already solve. I'd imagine using pulsed laser beams (no wires) across rooms/vast distances is a better conceptualization of "li fi"

I can imagine this working in incredibly specific scenarios, such as in clean rooms and other incredibly environmentally controlled situations, but wide spread? Why? It doesn't give any real benefit over wi-fi aside from being able to wirelessly transmit in a single, secure environment, where you want a 100% chance of there not being any leakage of data--and even then the electromagnetic fluctuations of the light flickering can be picked up on by a sufficiently determined hacker.

Still think lasers are a more sensible version of "li fi" esp if we use cheap green lasers. Extremely cheap (comparatively) and if we can switch them fast enough they can essentially transmit information for as high as your horizon is. That being said, if a bird flies through the beam, you're still kind of screwed.

This is going to be perfect for Scizos
Now every light will tick them off 😅

[Nebsgame]

I don’t want to alarm you but Your data is showing

[loveadeola]

I'm more concerned about the health impacts, especially long term.
