@@crnelious the signal doesnāt stop if thereās no direct connection to a router antenna. But youāre saying the visible light doesnāt 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 itās just a wi-fi router that also outputs waves in the visible spectrum, but doesnāt actually use those visible light waves to deliver signals.

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

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 theyāll shoot little holes in it with lasers. God I wish I was joking or insane.

Ok, so weāre just coming up withā¦ 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. Itās just too hard to get this to transmit at a bitrate that one can correct for environmental fluctuations, dust on the sensor, etc. I donāt really see how this actually would create benefits deployed large scale that wi-fi doesnāt already solve. Iād imagine using pulsed laser beams (no wires) across rooms/vast distances is a better conceptualization of āli fiā
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 doesnāt 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 dataāand 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 āli fiā 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, youāre still kind of screwed.
