Anon shares on Wifi Lightbulbs. Can anybody who knows of this topic shed some light?
If you haven't heard about "LIFI" you will.
Following is a brief explanation:
"At its essence, LiFi operates as a Visible Light Communications (VLC) system, promising unparalleled wireless internet speeds. Central to this system are LED light bulbs. These bulbs emit swift light pulses, imperceptible to the human eye, laden with information. It’s akin to an advanced, hyper-speed Morse code. Devices fitted with the requisite receivers decode this influx of data at breathtaking speeds. Demonstrated potential transmission rates for LiFi have even surpassed 224 Gbps, a pace that dwarfs WiGig, one of the most rapid Wi-Fi technologies."
The most sophisticated forms of A.I. cause airplane crashes and traffic accidents. Do you know how difficult it is for even a human operator to make sense of what someone is saying, if they are not speaking directly into a microphone? And where would that microphone be? LEDs are not microphones. Maybe you could cut down the monitoring by a factor of 10. That gets you down to 39 million monitors. That about 10 times as many personnel as we have in the department of defense. Still infeasible. And, you are not reckoning the number of false alarms produced by the A.I. system. Plus you still only have a light bulb connected to an electric socket. How do you retrofit an entire house-wide microphone and multiplexing (multiple conversations) communication system for 130 million households?
I read the same Wikipedia article that description came from. These are not just "LED light bulbs." They are LEDs as the back end of a communication system that has a light sensor, high speed data transmission, encoder-decoder electronics, and an LED...presumably pointed in the right direction. Satellite communication constellations are now implementing laser-communication systems, which are functionally identical. Other communication systems based on solar UV light have been proposed.
Li-Fi might replace Wi-Fi, but I have a hard time reconciling that with the superstitious fear of such things as 5G and 6G communication. Emission detectors should be easy to develop, since LI-Fi requires light modulation and are essentially anti-invisible. I wouldn't be too surprised if some bright inventor could develop a phosphor-coated glass cover that would pass the illumination through a phosphorescence delay that would defeat the high-speed modulation of the signal. But the "bulb" would only be an emitter, not a microphone, nor a camera. And who would it be emitting to? Fren, you have to realize that one must have a system concept that makes sense---not pick out one piece of technology and make it into an evil magic.
Gotcha. You have put me at ease as I've reluctantly purchased the bulbs myself due to not having an alternative
The bulbs are fine. They are very bright and very efficient. Best if you pick the high color temperature variety (color temperature near 6000 K). It's like broad daylight. The lower color temperatures look yellowish, like old incandescent light bulbs. Supposedly, some people like the lantern-colored light over daylight. Not me, but I live in a land where our sunlight is always muted by clouds. I'm not so sure the advertised lifetime is realized in practice, but the light is great. They make them as floodlight bulbs as well, in case you have outdoor lighting to deal with. Like my Dad used to say about lots of automobile horsepower: "When you need it, you gotta have it."
