@@crnelious the signal doesn’t stop if there’s no direct connection to a router antenna. But you’re saying the visible light doesn’t need to be seen directly to continue receiving the signal? Like you can have a li-fi table lamp in one room and receive Internet from it in another room still?
If so, it sounds like it’s just a wi-fi router that also outputs waves in the visible spectrum, but doesn’t actually use those visible light waves to deliver signals.

True, visible light is a part of the electromagnetic spectrum. But light has a much higher frequency than the microwaves that modern WiFi emit. Thus higher bandwidth.

Even if true, it needs to be differentiated from regular WIFI because users of Li-Fi must be aware of its limitations.. I imagine that there must be an unbroken line-of-sight path between the router and the transceiving port of the connected device.

All lightbulbs already have this. They use it to spy on us. If you put foil over your windows to block all light they’ll shoot little holes in it with lasers. God I wish I was joking or insane.

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.
