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."
It comes from cheapo LED replacements that break down over time. All white LEDs start off as strictly blue LEDs, and then use a yellow phosphor to convert most of that blue into yellow light, which both combine to average out into the white we see.
Well, if the yellow phosphor degrades or otherwise gets destroyed, you only get the purplish-blue of the original LED chip, and no longer white.
Thanks for this info. Very interesting and logical.
